Description

WALL FINISH MATERIAL AND METHOD FOR MANUFACTURING THEREOF

Technical Field

[1] The present invention is directed to a finish material and a method for manufacturing the same, and more particularly, to a finish material manufactured by processing a semi-jewelry material such as quartz, marble, crystal, a fossil tree, and ore into a thin plate, and a method for manufacturing the same. Background Art

[2] A finish material generally refers interior and exterior materials of architecture executed on internal and external walls or a floor of a building. In a broad sense, all materials used for finish-processing on surfaces of all articles used for daily life may be referred as a finish material.

[3] The finish material is required to have not only mechanical properties such as corrosion resistance and durability basically, but also excellent esthetic characteristics that provide visual beauty. External design is more important to all articles that are visually seen and touched in daily life.

[4] In recent years, semi-jewelry including quartz, marble, crystal, a fossil tree, and ore is preferred as the finish material. Such a natural or an artificial mineral material has good solidity to provide excellent characteristics in an aspect of the durability as well as beautiful and refined images in an aspect of esthetics because of changeable color according to a radiating angle of light. Therefore, a demand of the finish material using the semi-jewelry material is being increased. However, there are several problems when using the semi-jewelry material as the finish material of general architecture. First, it is difficult to process the semi-jewelry material into a sheet (thin plate) using a conventional technique and, thus, the semi-jewelry material used as the finish material is slightly thick. Moreover, the semi-jewelry material itself is so expensive that the cost is necessarily high if the semi-jewelry material itself is used as the finish material. Thus, the finish material using the semi-jewelry has necessarily degraded price competitiveness, which accordingly is difficult to be commonly used.

[5] As one method of using the semi-jewelry, the semi-jewelry material is processed in a sheet form. For this purpose, the semi-jewelry material should be primarily processed as the sheet. Then, the semi-jewelry material in the sheet form may be used as the finish material unchanged to lower he cost, but a mechanical strength of the finish material itself is deteriorated to liably incur warping phenomenon such as drooping. In a serious case, it is apt to be easily broken by external stimuli such as an external force and a shock. Therefore, it should have a sufficient mechanical strength. In considering the finish material of the general architecture using the semi-jewelry material, it is required to develop a finish material with a sufficient mechanical strength while decreasing manufacturing cost, and a method for manufacturing the same.

Mode for the Invention

[35] Embodiments of the present invention are described in detail in the detailed description and the accompanying drawings. The advantages and features of the present invention and a method of realizing the present invention will be clarified with reference to embodiments which will now be described more fully with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

[36] FIG. 1 is a plan view illustrating a finish material according to a first embodiment of the present invention, and FIG. 2 is a sectional view taken along a line II-II of FIG. 1. FIG. 3 is a perspective view schematically illustrating a sheet processing machine for processing a semi-jewelry material sheet applied to the finish material of FIG. 1, and FIG. 4 is a flow chart of a method for manufacturing the finish material illustrated in FIG. 1. FIG. 5 is a schematic sectional view illustrating a finish material according to a second embodiment of the present invention.

[37] When referring to the drawings but chiefly referring to FIG. 2, a finish material 100 according to an embodiment of the present invention includes four-story layer. That is, the finish material 100 includes a reinforcing plate layer 110 for preventing warping, and a semi-jewelry sheet layer 120 obtained by processing at least one of quartz, crystal, a fossil tree, and ore in a sheet form having a predetermined thickness, and disposed to one surface of the reinforcing plate layer 110 for preventing warping. Also, an adhesive resin layer 130 coated between the semi-jewelry sheet layer 120 and the reinforcing plate layer 110 for preventing warping to adhere the semi-jewelry sheet layer 120 onto the reinforcing plate layer 110 for preventing warping. An additive coating layer 140 is additively coated on the other surface of the reinforcing plate layer 110 for preventing warping oppositely disposed to the semi-jewelry sheet layer 120.

[38] The reinforcing plate layer 110 for preventing warping forms a basic frame in the finish material 100 according to this embodiment of the present invention. As will be described in detail later, the semi-jewelry sheet layer 120 has a thickness of several millimeters for enhancing price competitiveness of the finish material using the semi- jewelry. For this reason, if the semi-jewelry sheet layer 120 is used as the finish material untouched, warping or drooping phenomenon is apt to occur in the vertical direction of the plate surface due to a self weight or an external force. In turn, this phenomenon degrades an inherent mechanical strength of a thin semi-jewelry sheet 121 that is easily broken or destructed. Therefore, the reinforcing plate layer 110 for preventing warping is provided to reinforce the mechanical strength with respect to the semi-jewelry sheet layer 120.

[39] The reinforcing plate layer 110 for preventing warping may be selectively formed of glass, both-sided etching glass or stone, according to a place or an application of the finish material 100. When a glass plate 111 is selected as the reinforcing plate layer 110 for preventing warping, it may be applied where light is transmitted such as a window and a partition or illumination of other illuminating units (not shown) furnished within the finish material 100. Whereas, when a stone is applied as the reinforcing plate layer 110 for preventing warping, strength of the finish material 100 can be increased. This finish material 100 may be installed where an external force is frequently applied or on a portion easily exposed to an external environment. In this embodiment of the present invention, a glass plate 111 is used as a material constituting the reinforcing plate layer 110 for preventing warping. [40] The glass plate 111 may have excellent light transmission, which allows for utilizing optical characteristics of light such as scattering, polarization, and diffraction inherent in the semi-jewelry sheet 121. That is, the light is radiated to the finish material 100 bonded with the semi-jewelry sheet 121 using a light source radiating the light from the lighting unit within the finish material 100, so that the finish material 100 can be utilized as an interior item. In other words, when the glass plate 111 of the transparent material is used, the inherent color and optical characteristics of the semi-jewelry sheet 121 can be doubled using the transmission of the light. Furthermore, if an etched glass plate obtained by performing pretreatment upon the glass plate 111 is used, optical characteristics transformed due to the light compositely acting upon the semi-jewelry sheet 121 and the glass plate 111 may be used. The function as an interior item using the light transmission of the finish material 100 will be described in detail later.

[41] As described above, the semi-jewelry 55 (refer to FIG. 3) may include quartz, crystal, a tree fossil, and natural ore. Such the semi-jewelry 55 may be more elegant, refined and beautiful in an external appearance as compared with a material of general other internal and external finish material. However, most semi-jewelry 55 is a natural mineral picked under the natural state or an artificial mineral obtained by providing high cost for artificial fabrication. Therefore, supply quantity is not enough, and thus cost for re-processing is relatively high. Consequently, the semi-jewelry 55 is high in price to thus be restricted in an aspect of common use because of the disadvantageous manufacturing cost of articles using the semi-jewelry 55.

[42] As one method of solving the above- stated problem, the finish material 100 according to the present invention is contrived to equip the semi-jewelry sheet layer 120 that is obtained by slicing the semi-jewelry 55 to be processed as the semi-jewelry sheet 121 in a sheet form. The semi-jewelry sheet layer 120 is disposed to only one side of the reinforcing plate layer 110 for preventing warping. Therefore, when the finish material 100 is used as interior and exterior materials of architecture, the semi- jewelry sheet layer 120 becomes an exposed surface. The semi-jewelry sheet layer 120 may be provided by one kind of the semi-jewelry sheet 121 or a plurality of the semi- jewelry sheets 121. The plurality of the semi-jewelry sheets 121 may be provided by slicing the semi-jewelry 55 (refer to FIG. 3) that is a gemstone into the sheets having the substantially consistent thickness, and then being adhered to one another using an adhesive resin which will be described in detail layer. As a reference, the plurality of semi-jewelry sheets 121 having kinds and dimensions different from one another are illustrated in FIG. 1, but all semi-jewelry sheets 121 are designated by an identical reference numeral for a convenience of description.

[43] Cutting of the semi-jewelry material in the sheet form is conventionally difficult owing to using a saw as described above, so that the sheet processing machine as il- lustrated in FIG. 3 is used for processing the semi-jewelry sheets 121 in the sheet form from the semi-jewelry 55.

[44] First, a method for processing the sheet 20 will be briefly described. As illustrated in

FIG. 3, a plurality of wires 53 which are referred to as a saw are rotated, and the semi- jewelry 55 is cut by passing in the roughly vertical direction with respect to the advancing direction of the rotating wires 53. When performing the slicing, solid-state slurry (not shown) including abrasives (not shown) is supplied so that the abrasives and the wires 53 compositely act to each other, thereby slicing the semi-jewelry 55 that is the processed object.

[45] In view of the construction of the sheet processing machine 50 used in this embodiment, the sheet processing machine 50 includes a movement support frame 51, a plurality of rollers 52 wound with the wires 53, the wires 53 integrally turning around the rollers 52, and a slurry supply unit 54 disposed adjacently to the wires 53 to supply the abrasives to the rotating wires 53.

[46] The wires 53 used for the slicing is formed of a metal or fiber material, and a diameter of the wire 53 may be 0.16~0.2mm. The plurality of rollers 52 wound with the wires 53 number three in this embodiment of the present invention. The roller 52 has a guide groove (not shown) for being wound with the wires 53 by maintaining each strand of the wires 53 at a constant interval. Also, the roller 52 is connected to an AC servo motor (not shown) for being rotated at a speed of 500~2000meter per minute. When the wires 53 perform the slicing, the slurry is supplied as a support agent of the slicing. The slurry flown through the slurry supply unit 50 includes the abrasives that are GC cutting abrasives. The slurry according to this embodiment of the present invention has a solid-state granular form, but may have a liquid state form.

[47] Manufacturing of the semi-jewelry sheet 121 may be performed using the foregoing construction.

[48] To begin with, the semi-jewelry 55 is fixed to the movement support frame 51. Then, the motor is driven to rotate the rollers 52, so that the wires 53 turning around the rollers 52 are rotated in one direction. Here, the slurry including the abrasives is supplied from the slurry supply unit 50 disposed adjacently to the reciprocating wires 53 onto the wires 53. The semi-jewelry 55 provided in an Ingot form is vertically moved, grains (not shown) for abrasion within the slurry reciprocate with the wires 53, thereby being sliced. The slicing is similar to cutting mechanism of general machining.

[49] Such a single slicing using the plurality of wires 53 allows for mass production of the semi-jewelry sheets 121. A thickness of the semi-jewelry sheet 121 produced may be 3mm or so. The thickness of the semi-jewelry sheet 121 depends on the diameter and the arranging interval of the wires 53, which thus can be adjusted by changing the diameter and the arranging interval. Furthermore, since the dimensions of the semi- jewelry 55 that is the gems tone are different from one another, plate surface areas of the processed semi-jewelry sheets 121 are formed differently from one another.

[50] Meanwhile, as illustrated in FIG. 2, the adhesive resin layer 130 is formed to a chiefly a bottom adjacent to the semi-jewelry sheet 121. The adhesive resin layer 130 may include a ultraviolet (UV) hardening resin and a natural reaction hardening resin. The UV hardening resin is in a liquid form and then hardened upon radiating the ultraviolet rays. Accordingly, using a UV radiating apparatus (not shown), it can be rapidly hardened to allow for the mass production of the articles. Dissimilar to the UV hardening resin, the natural reaction hardening resin is hardened in a normal state, which requires roughly 24 hours and more but forms a thick resin layer. Both adhesive resins are excellently transparent to have good light transmission, and facilitate coating by the liquid form, which thus can be selectively used, as required. The coating for forming the adhesive resin layer 130 is largely classified into two.

[51] As a basic method, referring to FIG. 2, the semi-jewelry sheet 121 is disposed on the transparent plate 111, and then the adhesive resin may be coated. The adhesive resin in the liquid state flows through a gap between the semi-jewelry sheets 121, and perm eates through a space between the semi-jewelry sheet 121 and the glass plate 111 to form the adhesive resin layer 130. Further to this, the adhesive resin is sufficiently applied in the gap between the semi-jewelry sheets 121, thereby being filling in the gap. Consequently, the semi-jewelry sheet layer 120 may be bonded using the adhesive resin layer 130.

[52] On the other hand, after preparing the glass plate 111, the adhesive resin is coated on the entire surface of the glass plate 111 to form the adhesive resin layer 130 parallel with the plate surface of the semi-jewelry sheet 121 may be primarily formed. Then, the semi-jewelry sheet layer 120 is formed while disposing the semi-jewelry sheet 121 on the glass plate 111.

[53] The coating of the resin layer may be performed by separately using the above two methods or mixing them. This is determined by manufacturing circumstances, times, etc. of the finish material 100. For example, after coating the UV hardening resin on one side of the glass plate 111, the semi-jewelry sheet 121 is disposed and fixed, which is then exposed to a UV radiator (not shown), thereby rapidly forming the adhesive resin layer 130. Thereafter, the natural reaction hardening resin is applied thoroughly in the gap between the semi-jewelry sheets 121, and then the adhesive resin layer 130 is completed after elapsing 24 hours of hardening.

[54] The adhesive resin layer 130 becomes an exposed surface of the finish material 100 together with the semi-jewelry sheet layer 120, which therefore controls the quality of the articles. Accordingly, in order to remove the adhesive resin remaining on the exposed surface of the semi-jewelry sheet 121, and planarizing the adhesive resin layer, polishing of the exposed surface of the finish material 100 is required, which will be described in detail in a method for manufacturing the finish material 100. Also, quality inspection is performed after forming the adhesive resin layer 130 so that the adhesive resin may be repeatedly applied and hardened if the finish coating is imperfect, thereby additively forming the adhesive resin layer 130.

[55] By forming the adhesive resin layer 130, the semi-jewelry sheet 121 is adhered and fixed on the glass plate 111, and the plate thickness of the finish material 100 uneven due to disposing the semi-jewelry sheets 121 becomes consistent to enhance the quality of the finish material 100.

[56] The additive coating layer 140 is formed on the other surface of the reinforcing plate layer 110 for preventing warping oppositely disposed to the semi-jewelry sheet layer 120, which acts for blocking separation of particles of the glass plate 111 when an external force is exerted upon the finish material 100 to damage or break the glass plate that is the reinforcing plate layer 110 for preventing warping. At this time, the additive coating layer 140 may be formed by coating the adhesive resin identical to that of the adhesive resin layer 130.

[57] Further to the resistance against the external shock, the external force, etc., the additive coating layer 140 facilitates the cutting of the finish material 100 manufacturing using the method according to this embodiment of the present invention. Because it is manufactured to have a large-sized area owing to manufacturing cost, cutting is required so as to use the finish material 100 is used for the general architecture or articles for daily life. When performing the cutting, breaking of the glass is blocked to make the cutting be smoothly performed. Also, various material properties such as a thermal deformation rate and a thermal expansion coefficient of the adhesive resin layer 130 formed on one side of the glass plate 111 and the additive coating layer 140 on the other side thereof are made to be approximately similar, thereby minimizing the thermal deformation of the reinforcing plate layer 110 for preventing warping. That is, the identical adhesive resin is coated on one surface and the other surface of the glass plate 111, so that the warping in the thickness direction of the glass plate 111 caused during the hardening of the adhesive resin or a temperature variation condition.

[58] In this embodiment as described above, a predetermined sheet processing machine 50 is used for processing the semi-jewelry 55 into the semi-jewelry sheets 121 disposed on and adhered to the glass plate 111 that is the reinforcing plate 110 for preventing warping. Thus, the finish material 100 using the semi-jewelry 55 that is cheaper and retains a sufficient mechanical strength, thereby enhancing the durability can be manufactured.

[59] Additionally, the finish material 100 is valuable as a refined interior item due to the semi-jewelry 55. Particularly, during the daytime when natural light can be illuminated, a special value in terms of design from the inherent characteristics (e.g., the color and impression of the color) of the semi-jewelry 55 can be provided. In the nighttime, an illumination radiated from a light unit probably furnished within the finish material 100 penetrates through the finish material 100 to provide a mixed impression of the color by the illumination and the semi-jewelry 55. Furthermore, the finish material 100 may be used as a finish material of diverse daily articles as well as the interior and exterior materials of the general architecture. If it is used as an external finish material of a table, a closet, kitchen furniture, the enhanced design can be directed.

[60] A method for manufacturing the finish material 100 having the above structure will be described with reference to FIG. 4.

[61] First, a reinforcing plate layer 110 for preventing warping that forms a basic frame of the finish material 100 is prepared (Sl 1). Since a glass plate 111 is selected, the glass plate 111 is cut out to be fitted to the lateral and vertical widths of the finish material 100, thereby preparing the reinforcing plate layer 110 for preventing warping.

[62] Then, the plurality of a semi-jewelry sheets 121 processed in a sheet processing machine 50 are disposed to be parallel with the reinforcing plate layer 110 for preventing warping on one side thereof, thereby preparing a semi-jewelry sheet layer 120 (S12).

[63] Disposing of the semi-jewelry sheet layer 121 on the glass plate 111 is performed in a manner that the semi-jewelry sheet 121 of one kind is disposed on one side of the glass plate 111, or several kinds of the semi-jewelry sheet layers 121 are disposed on one side of the glass plate 111. This may be selected by considering the externally beautiful feature.

[64] When placing the plurality of semi-jewelry sheets 121 on the glass plate 111, it is required that the semi-jewelry sheets 121 secure an interval from each other not to overlap with one another. This is for securing a space where the adhesive resin permeates. If the semi-jewelry sheet 121 is overlapped, the bonding of the semi- jewelry sheets 121 using the adhesive resin may be degraded, and the external appearance may involve a problem. Moreover, the thickness of the finish material 100 may be inconsistent, and therefore, the semi-jewelry sheets 121 should not overlap with each other.

[65] Then, an adhesive resin is coated to make the semi-jewelry sheets 121 adhere onto the reinforcing plate 110 for preventing warping (S13). The applied adhesive resin and the method of coating equal to those as described above.

[66] Thereafter, in order to remove the adhesive resin remaining on the exposed surface of the semi-jewelry sheet 121, polishing of the exposed surface of the semi-jewelry sheet 121 is performed (S 14). When forming the adhesive resin layer 130, the adhesive resin is evenly coated on the entire surface of the finish material 100 without excluding the semi-jewelry sheet 121. Therefore, after the adhesive resin is hardened, it is required to remove residues of the adhesive resin coated on the entire surface of the plate. For this purpose, the plate surface of the finish material 100 is polished.

[67] Finally, in order to form an additive coating layer 140, the adhesive resin is coated on the other side of the reinforcing plate layer 110 for preventing warping where the semi- jewelry sheet layer 120 is formed (S 15). The additive coating layer 140 is formed by coating the adhesive resin having a component and a characteristic identical to those of the adhesive resin used for the adhesive resin layer 130, so that the additive coating layer 140 performs its own function.

[68] According to this embodiment of the present invention, the semi-jewelry 55 is processed to be the semi-jewelry sheets 121 using the predetermined sheet processing machine 50, which is used for the finish material 100. By doing so, the cost of the semi-jewelry 55 can be significantly decreased to heighten a possibility of commonly using the finish material 100 using the semi-jewelry 55.

[69] Also, the reinforcing plate layer 110 for preventing warping is prepared, and the semi-jewelry sheet 121 is bonded thereon to be formed as the semi-jewelry sheet 121. Therefore, the problems of weakening the mechanical strength of the finish material 100 itself and breakage of the finish material 100 resulting from the forming by the semi-jewelry sheets 121 can be solved.

[70] Furthermore, the finish material 100 has a value as a beautiful interior item due to the semi-jewelry 55. Particularly, during the daytime when natural light can be illuminated, a special value in terms of design from the inherent characteristics (e.g., the color and impression of the color) of the semi-jewelry 55 can be provided. In the nighttime, an illumination radiated from a light unit probably furnished within the finish material 100 penetrates through the finish material 100 to provide a mixed impression of the color by the illumination and the semi-jewelry 55. Furthermore, the finish material 100 may be used as a finish material of diverse daily articles as well as the interior and exterior materials of the general architecture. If it is used as an external finish material of a table, a closet, kitchen furniture, the enhanced design can be directed.

[71] Hereinafter, a finish material and a method for manufacturing the same according to another embodiments of the present invention will be described with reference to accompanying drawings in detail.

[72] FIGS. 5 through 7 are schematic sectional views of finish materials 200-400 according to second to fourth embodiments of the present invention. At this time, portions distinctive from those of the first embodiment will be described, and de- scription on equal construction will not be provided.

[73] FIG. 5 is a schematic sectional view illustrating a finish material according to a second embodiment of the present invention.

[74] The finish material 200 according to the second embodiment of the present invention is provided with a four-story layer as the first embodiment. That is, the finish material 200 according to the second embodiment includes a reinforcing plate layer 210 for preventing warping, a semi-jewelry sheet layer 220, an adhesive resin layer 230, and an additive coating layer 240.

[75] In case of this embodiment, the additive coating layer 240 is differentiated from that of the first embodiment. In the first embodiment, the additive coating layer 140 shown in FIG. 2 is formed by coating the adhesive resin, and a fiber glass 241 is added to the additive coating layer 240. In this case, the fiber glass 241 included in the adhesive resin acts as a frame of the additive coating layer 240 to fundamentally increase the strength of the additive coating layer 240. By doing so, the finish material 200 used for an actual architecture is stronger to external stimuli such as an outer force and shock according to usage of the finish material 200, and blocks scattering of glass pieces when broken to be relatively safer against an accident liably occurring due to separation of a glass plate 211. Furthermore, deformation such as warping of the finish material 200 apt to incurring caused by different thermal expansions of one surface and the other surface of the glass plate 211 can be prevented.

[76] As another characteristic, light polarization may be induced by the fiber glass 241 when the light transmits through the finish material 200. The fiber glass 241 may have the light transmission relatively different from that of the adhesive resin of the transparent substance. Thus, the light passing through the finish material 200 is affected by a weaving structure of the fiber glass 241 to obtain an effect similar to the polarization of the light.

[77] Also, the other surface of the finish material 200 may be embossed to widen an adhering area induced by the uneven surface of the other surface of the finish material 200, thereby facilitating the adhesion of the finish material 200.

[78] FIG. 6 is a schematic sectional view illustrating a finish material according to a third embodiment of the present invention. The finish material 300 according to the third embodiment is formed in a manner that semi-jewelry sheets 321 and 351 are formed on both sides of a glass plate 311 to be symmetric to each other, interposing the glass plate 311. Therefore, the semi-jewelry sheet layers 320 and 350 and adhesive resin layers 330 and 340 are respectively formed on both sides of the glass plate 311, and the layers 320, 330, 340 and 350 are similar to those described above.

[79] By doing so, the third embodiment has advantages of being beautiful in the esthetic appreciation, and relatively increasing the light transmission. Since the light is doubly transmitted through the semi-jewelry sheets 321 and 351, the finish material 300 has better optical characteristics than those of the above-described finish materials 100 and 200. The finish material 300 according to this embodiment may be employed where a semi-transparent substance such as a window and a partition member for sectioning spaces is required.

[80] FIG. 7 is a schematic sectional view illustrating a finish material according to a fourth embodiment of the present invention.

[81] The finish material 400 according to the fourth embodiment of the present invention does not employ the reinforcing plate layers 110, 210 and 310 different from the foregoing finish materials 100, 200 and 300. Instead, in the finish material 400 of the present invention, the semi-jewelry sheet layers 420 and 450 form two stories, and are adhered to each other. The finish material 400 includes the two-story semi-jewelry sheet layers 420 and 450, and an adhesive resin layer 430 for bonding them to each other.

[82] In this embodiment, a glass plate that is a reinforcing plate is omitted, so that a first sheet layer 450 of the semi-jewelry is disposed using a semi-jewelry sheet 451 as a method of reinforcing and supporting the semi-jewelry sheet layers 420 and 450. Then, a second sheet layer 420 of the semi-jewelry is formed using a semi-jewelry sheet 421. At this time, the second sheet layer 420 is obtained by placing the semi-jewelry sheet 421 to shield a spaced interval of the first layer 420. That is, the semi-jewelry sheets 421 and 451 are alternately disposed to inhibit coinciding of the spaced intervals between the semi-jewelry sheet layers 420 and 450 in a thickness direction.

[83] When manufacturing, the semi-jewelry sheet 451 is placed, and an adhesive resin is coated to complete the single semi-jewelry sheet layer 450 is completed. Then, a new semi-jewelry sheet layer 420 is disposed on an intersecting region, and bonded thereon. By doing so, the warping liably occurring due to the lack of the reinforcing plate can be slightly alleviated. Accordingly, the warping and drooping of the finish material 400 can be prevented while providing relatively better esthetic appreciation. Moreover, since the glass plate is omitted, the light transmission can be further increased. Therefore, the finish material 400 can be used where the light transmission is more important than the mechanical properties of the finish material 400.

[84] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
