Description
Technical field
The present invention relates to method and a kind of paper that adopts this method to make that a kind of manufacturing is used for the paper of sheet material, the invention still further relates to a kind of sheet material that adopts paper to make, and corresponding method of manufacture.
Background technology
Sheet material of the present invention can continue to be processed into panelling.Normally a kind of elongated thin sheet material of a kind of panelling of putting down in writing in patent documentation EP 090 6994 A1 for example for example can be connected with other panelling with spring by groove with cross side in vertical side of this sheet material.The panelling that adopts this mode to interconnect is particularly useful for as floor or circummure.
A kind of sheet material is as follows according to the manufacture method of prior art.Prepare a kind of paper that also is known as " back tension paper " with resin impregnation.At this hone lamella is set above the back tension paper.An other paper with resin impregnation is arranged on the hone lamella.Is that mutual extrusion becomes sheet material under the situation about 200 ℃ with two pieces of paper and hone lamella in temperature.
The paper that is provided with on hone lamella has clocklike usually to be decorated, and this decorates the outward appearance of decision sheet material upside.Before extrusion process, to the upper side roll extrusion silicon-carbide particle or the corundum in granules of decorating, so that obtain the sheet material with special wearing face.To also adhering to a cellulose layer on the face with silicon-carbide particle or corundum.
The paper that has the impression decoration is known as facing paper.Cellulose layer is known as " coating ".
The facing paper that has coating is arranged on above the hone lamella.So facing paper is between hone lamella and coating.Then back tension paper, hone lamella, facing paper and coating mutual extrusion under the temperature about 200 ℃ is in the same place.When this layer system leaves forcing press, then formed sheet material, on a face of this sheet material, have a decoration that has a hard especially surface.
By saw or mill sheet material can be made have required specification, panelling that the side is provided with spring and groove.Described panelling is specially adapted to as the floor.
Hone lamella can provide the mechanical stability of panelling.Decoration on the facing paper is determining the later circummure surface or the outward appearance of floor surface.By corundum or SiC
2The layer that constitutes is used to realize performances such as high abrasion resistance strength.The back tension plate is used to overcome the buckling deformation of hone lamella.Coating is used for the forcing press surface is protected, otherwise will be subjected to the hard SiO of projection
2-or the wearing and tearing of corundum in granules.
The common gram number of the paper that adopts according to prior art greater than 70 grams/square metre.If be lower than above-mentioned value, then the tearing toughness of paper is not enough to overcome the mechanical load that produces when making sheet material.Paper must be very thin in addition, so that it is very transparent, is applied thereby can be used as facing paper.
Clearly, the shortcoming of high gram number paper is that material consumption is corresponding higher.Wherein not only to consider the intrinsic gram number of paper, but also will consider when making sheet material for used paper being carried out the weight of the resin of impregnation process.The gram number of paper is high more, and it is just many more then paper to be flooded the resin that needs use.Certainly will cause expensive paper manufacturing cost like this.
For the paper of the anti tear that obtains to approach, must be to applying one deck plastic hybrid on the paper of handling through pre-preg.This plastic hybrid does not immerse in the paper, but forms additional and layer paper adjacency.The another side of paper has the self-adhesive layer usually.The paper that adopts this mode to make is known as " glazing film " and can be bonded on the sheet material.
Summary of the invention
The objective of the invention is to make and propose a kind of paper, the tearing toughness of this kind paper improves greatly and its design is considered compared with the prior art can be coated with color from visual angle.The present invention also aims to make and propose a kind of cheap sheet material, in this sheet material, used paper of the present invention.
The method according to this invention adopts the dispersant or the mixture that contain acrylates to carry out impregnation process to paper.Compare with the paper that only adopts resin to flood, adopt the tearing toughness of the paper of the inventive method dipping to be significantly improved.The gram numerical example of paper as be 30 grams/square metre, however still can bear the mechanical load that when making sheet material, produces.The results showed that the mechanical strength of paper of the present invention is very high, so that the speed of the impregnating resin stipulated can be brought up to 120 meters/minute by so far 40 to 60 meters/minute when making sheet material.Compared with the prior art, also corresponding less to the consumption of paper and impregnated material.
The dispersant or the mixture that contain acrylates comprise water, and acrylates is disperseed in water.So suitable acrylates is those acrylates that can fully disperse.
According to a kind of useful design of the present invention, for realizing that flooding the dispersant or the mixture that will contain acrylates is squeezed in the paper.For this reason, the roll shop building of two mutual roof pressures of paper is passed through.On a roll, apply dispersant or the mixture that contains acrylates continuously.When paper left roll, dispersant or mixture were squeezed in the paper.
Importantly, dispersed acrylates or mixture not only are applied on the paper simply, otherwise dispersed acrylates or mixture can not or can not enter in the paper fully.Guaranteed that by extruding dispersant or mixture immerse the improvement that also therefore makes the required intensity of paper realization in the paper.In addition, the dispersant that has of paper or mixture are enough to make that the additional resin that adopts can not immerse or can only immerse in the paper at least micro-ly when continuing to be processed into sheet material.
According to a kind of useful design of the inventive method, before the dispersant that will contain acrylates or mixture are squeezed into paper, to the paper processing of ventilating.Adopt the dispersant or the mixture that contain acrylates particularly the one side of paper to be flooded for this reason.The air that exists in paper is replaced by dispersant or mixture.
According to one embodiment of the present invention, adopt resin-propylene hydrochlorate-mixture or-dispersant, especially amino resins-acrylates-mixture carries out impregnation process.Adopt this mixture or dispersant can realize approximately reaching 15 grams/square metre the lower limit of paper gram number.When mixing match is suitable, adopt the paper of this method manufacturing for example can realize being enough to when making sheet material tearing toughness as withstand voltage body paper.The professional can find out suitable mixing match by a little test.
The gram number of paper must not surpass the upper limit 60 grams/square metre, preferably must not surpass 40 grams/square metre, thereby can realize fully high cost advantage.At present the optimum value of gram number 25 to 35 grams/square metre between.
According to a kind of useful design of the present invention, can be with such as alumina silicate, calcium carbonate, TiO
2, Al
2O
3Or pigment such as magnesium silicate is added in the mixture.Reduce its light transmission greatly with this.
Adopting under the situation of pigment, because its opaqueness that has and high covering power, thereby be highly suitable for as facing paper through the paper of impregnation process.
According to of the present invention preferred embodiment a kind of, the dispersant or the mixture that contain acrylates are squeezed into through the paper of handling that ventilates from the two sides.Verified, paper begins to be full of dispersant or the mixture that contains acrylates from the centre.This paper through impregnation process is specially adapted to described sheet material processing.
The paper made according to the method for the present invention and the difference of glazing film are that especially acrylates is present in the paper, and not only fully or the overwhelming majority float over paper surface.Show described glazing film when the anti-decomposition intensity of this paper is better than this specification significantly and begins through steam test.When carrying out steam test, paper will be accepted the processing of two hours steam.Compare with paper of the present invention, will occur on the common paper decomposing.
Paper of the present invention is applicable to the processing of described sheet material as back tension paper or facing paper.
According to a kind of design of the inventive method, on a face of facing paper, not only have wear-resistingly such as silicon-carbide particle or corundum in granules, but also additionally have fiber and/or a spheroid.Compare with wear-resisting particle, fiber or spheroid are by constituting such as soft materials such as polyester, polyamide or glass.Fiber and/or spheroid are used for can not sustaining damage carrying out the compressive zone that layer system when extruding protection ring encloses facing paper.Therefore, on have the layer of abrasion resistant particles, coating can be set.Can save about 1/3 cost like this, this cost system comprise when adopting prior art to the impregnation process cost of facing paper together with the cost that is covering of the layer that has coating.
The facing paper impregnation process is especially comprised the steps.Adopt resin, particularly amino resins that facing paper is carried out impregnation process, and the one side that has decoration is being covered abrasion resistant particles.Then covering fiber and/or spheroid thereon.So promptly can realize the cover layer that on abrasion resistant particles, forms to the pressure apparatus protection.
The processing method of being carried out before fiber or spheroid are being covered is as follows.
The layer that on facing paper, constitutes by amino resins and abrasion resistant particles with specific decentralization additional spraying one deck, wherein the weight with dry body paper is 100%, final weight per unit area is 250%.Learn by document WO 00/44984, verified, be useful to the spraying of dispersant.Then should adopt roll to guarantee the fineness of the dispersant sprayed and evenly distribute.
Above-mentioned dispersant is preferably by 100 parts of amino resins, 20 to 95 parts of attrition resistant materials, 0.5 to 2.5 part of silane bonding agent, 5 to 25 parts of mobile assistants, 0.1 to 0.4 part of wetting agent, 0.05 to 0.4 portion of release agent and amino resins curing agent.
Particularly adopt melmac as amino resins, as the auxiliary substance that flows for example adopt polyglycol ether, 'epsilon '-hexanolactam or butanediol and as attrition resistant materials for example adopt particle mean size be the carborundum of 60 to 160 μ m occur with the corundum form or be the aluminium oxide that 60 to 160 μ m fused mass constitute by granularity.Also can adopt the mixture arbitrarily that constitutes by carborundum and aluminium oxide.
Then should cover fiber and/or spheroid in the following way.At first make a kind of mixture that constitutes by resin, fiber or spheroid and mixture is coated on the facing paper through handling in the above described manner.Mixture is arranged on the surface can further improves protection to pressure apparatus, this is because additional resin also will play protective effect.
The thickness of preferred selected fiber or the diameter of spheroid should make in sheet material process, make corresponding layer system extruding corundum-or silicon-carbide particle away from the corresponding surface of forcing press.Thereby will avoid being subjected to hard carborundum-or the damage of corundum in granules.
When both adopting fiber, when adopting spheroid again, the average diameter of spheroid is preferably greater than the average diameter of fiber.Spheroid will guarantee abrasion resistant particles and for example required protection interval between the press belt this moment.Fiber is particularly useful for the fixing of resin and prevents crackle.
Adopt the present invention with improve and can realize the relevant surface of forcing press is protected in the cheap especially mode of cost, avoid being subjected to abrasion resistant particles, for example hard corundum in granules or the damage of silicon-carbide particle.Because the corresponding relevant surface that has increased a forcing press, for example the press belt to a so-called biobelt-laminating apparatus carries out the time interval that finishing is handled, thereby certainly will reduce the expense that finishing handles and the number of times and the time of stopping production followed.So provide cost savings significantly.
Typical fibre length is at least 0.5mm, but preferably is at least several millimeters, for example 2mm, 4mm or 5mm.Fiber is long more, can prevent better more that then crackle from appearring in plate surface.Especially decide the upper limit of fibre length by the increase of the viscosity that interrelates therewith.When the viscosity of resin-fiber-mixture is too high, then no longer can processed to it.The diameter of fiber for example is tens microns or even equals 100 μ m or greater than 100 μ m.
The typical diameter of spheroid is in 30 to 200 mu m ranges.Therefore, can guarantee on the one hand the required interval between the corresponding surface of corundum in granules or silicon-carbide particle and forcing press, spheroid is fully little on the other hand, makes naked eyes invisible.
When fiber or spheroid had in above-mentioned specification and the embedded resin, then fiber and spheroid can not cause adverse influence to visual effect.
Fiber or spheroid preferably are made of polyester, polyamide or glass.Required performance requirement after these materials satisfy when producing and manufacturing finishes.In process of production, these materials keep stable fully.Polyester, polyamide or glass are the abundant soft materials that can avoid pressure apparatus to sustain damage that the present invention defines.On the sheet material of a finished product, realize sufficient transparency, thereby can not cause adverse influence the visual effect of decorating by above-mentioned material.These materials can be realized bigger machinable fibre length valuably, and this fibre length can increase the length of the fiber of the present invention's employing that is made of cellulose significantly.Promptly compare, along with such as the increase of man-made polymers' such as polyester fiber, polyamide fiber or glass fibre fibre length and the raising of viscosity is very little with the length of the cellulose fibre that increases.
So can add fully many fibers, can protect forcing press to avoid damage better thereby compare with short cellulose-fiber.When fiber exists with the nonwoven fabric form that below will be explained, be exactly this situation particularly.
Fiber and/or spheroid can be made of different materials.For example can adopt polyester fiber, polyamide fiber and glass fibre simultaneously.
Compare with spheroid, preferably use fiber, because can avoid at surface formation crackle.Preferred addition adopts spheroid.So be added into the hollow ball that preferably constitutes by glass as spheroid so that improve the protection effect, for to the diameter of the consideration spheroid of above-mentioned reason especially in 30 to 200 mu m ranges.
The solid weight that facing paper of the present invention preferably has be 25 to 35 the gram/square metre.The fiber component is especially in 5 to 100 gram/square metre scopes.In addition in order to strengthen, should adopt reach 80 grams/square metre spheroid, especially little glass hollow ball.
