Description

Method for applying a decorative layer detachably adhering to a carrier film to profiles and film structure therefor

The present invention relates to a technique for applying a decorative layer releasably adhered to a carrier film to an object. More particularly, the present invention relates to a method, an apparatus and a system for applying a decorative layer releasably adhered to a carrier film to an object and a film structure for an object. The object may be, for example, a plastic profile.

Plastic profiles for outdoor use, such as window or door profiles, are subject to constant weather conditions. These are irradiated by the sun, which allows them to build up a temperature of more than 55 ° C. This increased temperature in the plastic profiles can change the shape of the plastic profiles. For example, the plastic profiles can deform or warp concave or convex. The plastic profiles deform the easier the bigger they are. For example, the shape of plastic profiles for large windows can change greatly in high sunlight. The problem of deformation or warping of plastic profiles is still increasing, if the

Plastic profiles are installed in the upper floors of a skyscraper, since there is generally an even higher solar radiation acts.

To increase the aesthetics of plastic profiles, these are often laminated with a polyvinyl chloride (PVC) film. The PVC film has a decor, such as a wood decor, and is glued to the plastic profiles. To reduce the heating of plastic profiles by solar radiation, it is known to integrate a protective layer for ultraviolet (UV) radiation in the PVC film. By such a UV protective layer but can not be achieved (especially at high solar radiation) often sufficient suppression of temperature increase in the plastic profiles.

In addition, built-in plastic profiles must meet a variety of standards in terms of fire and fire protection. So it is desired that plastic profiles for buildings have a flame retardant effect. The flame retardant effect should be such that people can still be evacuated from a building in fire. The well-known Plastic profiles with laminated PVC film, however, do not provide adequate flame retardancy in this respect.

It is also known to apply decors to 5 plastic profiles by means of a so-called "release technique." In the release technique, a decor that is releasably adhered to a carrier film is removed by means of a so-called "release agent" (ie, a release agent) applied a plastic profile.

Carrier films which have a release property and a use of a such carrier film for applying a decoration to a substrate are known, for example, from document EP 0 573 676 A1.

However, such applied by means of the release technique on plastic profiles decors have no Temperaturerhöhungsvermeidende and / or i5 flame retardant effect.

It is an object of the present invention to provide a technique for applying a decorative layer releasably adhered to a carrier film to an object, with the aid of which a temperature increase in the object can be reduced and the object receives a flame-retardant effect.

According to the invention, this object is achieved by a method for applying a decorative layer releasably adhering to a carrier film to an object, wherein the decorative layer has a decor and a metal layer, with detachment of the decorative layer from the carrier film, applying the decorative layer to the object, so that the Metal layer between the decor and the object is arranged and painting the decorative layer with a flame-retardant lacquer layer, so that the decor between the flame-retardant lacquer layer and the object is arranged. 0

The object may be any kind of object, in particular a plastic profile, for example a window, door or façade profile. The carrier film has a release property, so that the decorative layer releasably adheres to the carrier film. The release technique has the advantage that the decorative layer 5 can be applied to the object in a simple and cost-effective manner at high production speeds. The flame-retardant lacquer layer arranged on the outside of the object delays or prevents the spread of flames or fire. The metal layer arranged closer to the object than the flame-retardant lacquer layer reflects solar radiation, in particular UV radiation, and heat to the outside from outside. As a result, it counteracts a temperature increase, ie a heat accumulation, in the object. In addition, the flame-retardant effect of the flame-retardant lacquer layer is enhanced by the heat or radiation reflection of the metal layer. Consequently, with the aid of the metal layer and the flame-retardant lacquer layer, it is possible to provide a film structure for an object which, on the one hand, reduces a temperature increase in the object and, on the other hand, has a flame-retarding effect.

Furthermore, by the interaction of the decor. (For example, a wood decor) with the underlying metal layer, a three-dimensional decorative effect can be generated. It appears by light reflections on the

Metal layer the decor of the plastic profile for the viewer three-dimensional. This can be dispensed with a decor with a three-dimensional profile on which easily dirt particles can accumulate. As a result, the cleaning effort can be reduced. In addition, the production of a three-dimensional profile is associated with higher production costs, which is why avoiding a three-dimensional profile leads to cost savings.

To promote the three-dimensional decorative effect, the decor for the human eye imperceptible or have the optical impression of the decor not affecting gaps by which incident electromagnetic radiation, in particular light radiation, is reflected directly on the bare surface of the metal layer. The flame-retardant lacquer layer can be designed to be transparent and / or likewise have gaps that are imperceptible to the human eye or that do not influence the visual impression of the decoration. In particular, the decor may be porous.

The object stated in the introduction is also achieved by a method for applying a film structure releasably adhering to a carrier film to an object, wherein the film structure has a decorative layer with a decor and a metal layer and a flame-retardant lacquer layer and the decoration between the metal layer and the flame-retardant Paint layer is arranged, with detachment of the film structure of the carrier film and applying the film structure to the object, so the decoration is arranged between the flame-retardant lacquer layer and the object. In this case, the film structure, comprising the decorative layer with the decor and the metal layer and the flame-retardant lacquer layer, at once detached from the carrier film and applied to the object. The flame-retardant lacquer layer is preferably designed to be flexible.

In order to reflect incident radiation and acting heat well, the metal layer may have a thickness of 1 μm to 5 μm, in particular from 2 μm to 3 μm. The metal layer may have been vapor-deposited onto the decor by means of a vacuum metallization process.

The metal layer may further comprise steel pigments. The steel pigments reflect incident radiation, in particular UV radiation, and acting heat. A metal layer with steel pigments can in particular be produced more cost-effectively than for example a silver or aluminum layer.

According to one embodiment, the flame-retardant lacquer layer may have a smooth surface on the side facing away from the decor. This smooth surface prevents dirt particles from settling on the lacquer layer. In known wood decors, a three-dimensional profile is used to make the decor look more natural. The three-dimensional profile is applied with at least one separate embossing process, which leads to increased production costs. The avoidance of such a three-dimensional profile, i. the provision of the smooth surface of the flame-retardant lacquer layer is made possible in particular by the interaction of the decoration and the underlying metal layer.

To improve the three-dimensional effect, the flame-retardant lacquer layer may be formed at least partially transparent. The flame-retardant lacquer layer may also be formed scratch and ritzfest, so that damage to the object difficult or avoided.

In order to enable a good flame retardance, the flame-retardant lacquer layer can have a thickness of 35 μm to 65 μm, in particular from 45 μm to 55 μm. The flame-retardant lacquer layer is preferably solvent-free and anhydrous. The flame-retardant lacquer layer may also have a solids content of greater than or equal to 95%. The flame-retardant lacquer layer preferably consists of resins and / or inorganic pigments, the inorganic pigments forming a flame-retardant upper layer in the lacquer layer.

The decor can have a thickness of 2μm to 3μm. The decor may have been printed in one or more printing operations on the Trägerfllm. In particular, several decorative colors may have been printed on the carrier film.

In order to enable high production speeds, the carrier film may have a thickness of 15 μm to 100 μm, in particular of 30 μm to 60 μm. As a result, a carrier film can be provided which can also be used at high throughput speeds without bubbles forming or the carrier film folding.

The carrier film may be a film of polypropylene (PP) or polyester. The carrier film may also be a sandwich structure of at least three layers in which the middle layer has a lower stiffness than the outer layers. The outer layers may consist of polypropylene and the middle layer of polypropylene foam. Alternatively, the outer layers may be polyethylene and the middle layer may be polyethylene foam. The two outer layers of the sandwich structure can in particular have the same rigidity. The sandwich structure of the carrier film can further improve the prevention of wrinkling at high processing speeds.

Preferably, a release agent, that is a release agent, arranged to detach the decorative layer of the carrier film between the decor and the Trägerfllm. In this case, the release agent can provide the release property.

The release agent may have a thickness of 1 μm to 2 μm. The release agent may in particular comprise alcohol wax and / or water. As a result, the decorative layer adheres to the carrier film, but can still be easily detached (for example, by heating and printing) of the carrier film. For applying or attaching the decorative layer to the object, the metal layer may have a thin adhesive layer on the side facing away from the decor. Through this thin adhesive layer, the decorative layer can be attached to the object. The adhesive layer may have a thickness of approximately 1 μm.

The object stated at the outset is also achieved by a system for applying a decorative layer detachably adhering to a carrier film to an object, wherein the decorative layer has a decor and a metal layer, with means for detaching the decorative layer from the carrier film, means for applying the decorative layer to the object An object, wherein the means for applying are adapted to apply the decorative layer to the object in such a way that the metal layer is arranged between the decoration and the object and with a painting device for coating the decorative layer with a flame-retardant lacquer layer, wherein the painting device is adapted to to paint the flame-retardant lacquer layer so that the decoration between the flame-retardant lacquer layer and the object is arranged.

The means for detaching the decorative layer from the carrier film may be, for example, a heating device designed as an ultrasonic roller, which heats the carrier film and / or the decorative layer, so that the decorative layer can be detached from the carrier film. The means for applying the decorative layer to the object may be a heatable detaching roller and the painting device may be a vacuum painting device which sprays the flame-retardant paint layer onto the decor under vacuum.

The object stated in the introduction is further achieved by an apparatus for applying a film structure releasably adhering to a carrier film to an object, wherein the film structure has a decorative layer with a decor and a metal layer, and a flame-retardant lacquer layer and the decoration between the metal layer and the flame-retardant lacquer layer, with means for detaching the film structure from the carrier film and means for applying the film structure to the object, wherein the means for applying are adapted to apply the film structure to the object such that the decoration between the flame-retardant lacquer layer and the Object is arranged. The invention also relates to a film structure for an object with a decorative layer, comprising a decor and a metal layer, and a flame-retardant lacquer layer, the decoration being arranged between the metal layer and the flame-retardant lacquer layer. The object may be, for example, a PVC or plastic profile of a window, a door or a facade.

Preferably, the decorative layer is adapted to be releasably connected to a carrier film.

In one embodiment, the decorative layer furthermore has a thin adhesive layer, which is arranged on the metal layer and configured to firmly connect the film structure to the object.

The decor may be arranged on the metal layer. Furthermore, the flame-retardant lacquer layer can be arranged on the decor.

The invention will be further elucidated below with reference to the accompanying drawings by means of exemplary embodiments. Show it:

Figure 4 is a schematic representation of the structure of a plastic profile with a decorative layer and a flame retardant lacquer layer

Figure 1 shows schematically an embodiment of a system for applying a releasably adhered to a carrier film decorative layer on an object.

The system 100 comprises a device 105 for detaching a decorative layer from a carrier film and for applying the decorative layer to an object, a vacuum Painting device 110 and a paint drying device 115. Plastic profiles 120, 122, 124 successively pass through the device 105, the vacuum painting device 110 and the paint drying device 115 at a certain adjustable speed.

The device 105 is configured to apply a decorative layer to the plastic profiles 120, 122, 124. In the device 105, the decorative layer is detached from the carrier film and applied to the plastic profile 122 by a carrier film with a decoratively adhering decorative layer, which is referred to below as film 126.

An exemplary schematic structure of the film 126 is shown in FIG. The film 126 comprises a carrier film 128, a release agent 130, a wood decor 132, a metal layer with steel pigments 134 and a thin adhesive layer 136. The individual layers are arranged directly on one another, the wood decor 132 lying between the carrier film 128 and the metal layer 134 , The decor 132 and the metal layer 134 is a decorative layer 138. As a result, the decorative layer 138 releasably adheres to the carrier film 128 with the aid of the release agent 130. Another release agent 137 may be disposed on the adhesive layer 136 to allow the release layer 136 to adhere Film 126 rolls in rolled up state, ie the carrier film 128 does not stick to the adhesive layer 136.

In the embodiment of Figure 2, the support film 128 have a thickness of 50 microns, the release agent 130 has a thickness of lμm, the wood decor 132 has a thickness of 2 microns, the metal layer 134 has a thickness of 2 microns, the adhesive layer 136 has a thickness of lμm and the Release Agent 137 has a thickness of lμm. The carrier film 128 is made of a sandwich structure (not shown) having two outer layers of polypropylene and an inner layer of polypropylene foam. Due to the sandwich structure, the carrier film 128 on the one hand has such a flexibility that it can pass through the device 105 at high speeds. On the other hand, it is so stiff that it does not wrinkle even at high speeds.

To produce the film 126, the wood decor 132 was printed by means of a printing process on the release agent 130 and the carrier film 128, respectively. The printing process was performed by a printing machine (not shown), which the wood decor 132 in several printing steps on the release agent 130 and the Carrier film 128 has printed. The printing press comprises a gravure cylinder (not shown) for each printing step. In the present embodiment, the wood trim 132 was printed in four printing steps on the release agent 130 and the carrier film 128, respectively. To create a good visual effect, four wood colors were printed on Release Agent 130.

Furthermore, to produce the film 126, the metal layer 134 was vapor-deposited by means of a vacuum metallization apparatus (not shown) on the side of the wood decor 132 facing away from the carrier film 128, and then the adhesive layer 136 on the side facing away from the wood decor 132

Metal layer 134 applied. It is also conceivable that first the metal layer 134 and then the wood trim 132 are applied.

As can be seen in FIG. 1, the film 126 in the device 105 is rolled up on an unwinding roller 140. The film 126 is rolled up on the unwinding roll 140 such that the carrier film 128 faces inwardly toward the center of the unwinding roll 140 and the adhesive layer 136 in the opposite direction, i. to the outside, is directed. The unwind roll 140 is rotatably mounted and configured to allow the film 126 to be unwound from it in a clockwise direction. Due to the release agent 137, the carrier film 128 can be detached from the adhesive layer 136 in the rolled-up state.

The film 126 travels from the unwinding roll 140 via a deflection roll 145 to an ultrasonic roll 150. Further deflection rolls (not shown) may be provided. Further, a preforming roller (not shown) for preforming the film 126 may be provided between the unwinding roller 140 and the ultrasonic roller 150. The preforming roller may be designed to be movable in at least two directions which are perpendicular to the surface of the carrier film 128 and have a profile on its peripheral surface in order to prepare the film 126 for the release process.

The ultrasonic roller 150 is an ultrasonic sonotrode formed as a rotatably mounted roller, which emits ultrasonic waves to the film 126 and generates oscillations therein. The high-frequency vibrations heat the film 126. The ultrasonic roller 150 rotates with the same

Speed as the film 126. With the aid of the ultrasonic roller 150, the film 126, even at high throughput speeds, ie up to 30m / min, sufficient to be heated. In addition, the film 126 can be heated over its entire thickness. Alternatively, the film 126 may also be heated by other heating elements (such as infrared heaters or oil heaters).

At the ultrasonic roller 150, the film 126, i. the adhesive layer 136, the first time in contact with the plastic profile 122. At this time, the ultrasonic roller 150 presses on the film 126 at a first pressing point 152, i. the carrier film 126, and provides a connection between the film 126 and plastic profile 122 ago.

Alternatively, the ultrasonic roller 150 may also deliver the ultrasonic energy to the film 126 without contact. In this case, the ultrasonic roller 150 may be disposed at a distance of about 1 mm from the film 126. In this case, a further roller (not shown) may be provided, which supports the film 126, i. the adhesive layer 136, with the plastic profile 122 brings into contact.

A counter roller 155 arranged with respect to the film 126 and the plastic profile 122 with respect to the ultrasonic roller 150 allows the film 126 to come into contact with the plastic profile 122. Counter roll 155 may be an anvil roll. The ultrasonic roller 150 and the rotatably mounted counter roller 155 press the plastic profile 122 and the film 126 together and guide it through the device. In order to avoid tilting between film 126, plastic profile 122, ultrasonic heating 150 and counter roller 155, the ultrasonic roller 150 and / or the counter roller 155 may be movably mounted in a direction substantially perpendicular to the film 126 and the plastic profile 122.

Alternatively, the ultrasonic roller 150 and / or the backing roll 155 may also be located further upstream in the apparatus 105, with the ultrasonic roll 150 heating the film 126 before first contacting the plastic profile 122. In this case, the counter-roller 155 can be dispensed with.

For machine transport of the film 126 and the plastic profiles 120, 122, 124 by the device 105, this further comprises a rotatably mounted drive roller 160 which is driven by means of an electric motor (not shown) in the counterclockwise direction. The rotational speed of the electric motor or drive roller 160 is variably adjustable. Furthermore, at least one rotatably mounted Feed roller 165 provided by means of which the plastic profiles 120, 122, 124 can be conveyed in the device 105.

After the film 126 has been heated by the ultrasonic roller 150, it is fed to a detaching roller 170 together with the plastic profile 122. The release roller 170 is rotatably mounted and presses with a predetermined contact pressure at a second pressure point 171 on the film 126, i. the carrier film 128. The plastic profile 122 and the film 126 are guided between the detaching roller 170 and the drive roller 160. If the drive roller 160 is not arranged opposite the detaching roller 171 as shown in FIG. 1, then instead of the drive roller 160, a further counter roller (not shown) may also be provided.

The distance between the first pressing point 152 and the second pressing point 171 may be 3cm to 8cm. In the present embodiment, the distance is 5cm. In particular, the distance between the first pressure point 152 and the second pressure point 171 can be selected such that no significant temperature drop occurs on the film 126 between the pressure points 152 and 171.

The detaching roller 170 is made of silicone or a silicone foam on its circumferential surface 172 and has a profile. The peripheral surface 172 is heated by means of three infrared radiators 175. The number of infrared heaters 175 is not limited to the number of three. In principle, it is advantageous to heat the largest possible area of the circumferential surface 172. Other means of heating the peripheral surface 172 may be used.

With the help of the heated peripheral surface 172 of the detaching roller 170, the heated by means of the ultrasonic roller 150 film 126 and the pressure exerted by the peel roller 170 on the film 126 and the plastic profile 122 pressure can

Decorative layer 138 detached from the carrier film 128 and applied to the plastic profile 122, i. glued on. After the detaching roller 170, the carrier film 128 rests only on the decorative layer 138, and the decorative layer 138 is firmly connected to the plastic profile 122 with the aid of the adhesive layer 136.

The carrier film 128 and the plastic profile 122 with the decorative layer 138 adhered thereto are subsequently fed to a deflecting roller 180. there For example, the carrier film 128 and the plastic profile 122 with the decorative layer 138 adhered thereto are fed to the deflection roller 180 at the same speed.

At the deflection roller 180, the carrier film 128 is finally separated from the decorative layer 138. For this purpose, the carrier film 128 is fed to the deflecting roller 180 of a rotatably mounted winding roller 185. The take-up roll 185 is rotated clockwise by an electric motor (not shown) and rolls the carrier film 128 thereon. The rotational speed of the winding roller 185 and the electric motor is adjustable. In particular, a control (not shown) is provided, which controls all drive elements of the device 105, in particular the drive roller 160 and the winding roller 185, that the plastic profiles 120, 122, 124 and the film 126 or the carrier film 126 and the decorative layer 138th go through the device 105 synchronously.

Furthermore, after the deflection roller 180, a cutting device (not shown) may be provided, which cuts through the decorative layer 138 before and after each plastic profile 122 or cuts off any excess decorative residues. After the deflection roller 180, the plastic profile 122 is transported with the decorative layer 138 from the device 105.

The plastic profiles 122 and the film 126 or the carrier film 126 and the decorative layer 138 pass through the device 105 at the same speed. Preferably, they pass through the device 105 at a speed of 20m / min to 30m / min. Due to the structure of the film 126 and the structure of the device 105, a high throughput speed is possible without the film 126 forming wrinkles.

FIG. 3 shows a schematic representation of the structure 190 of the plastic profile 122 with the decorative layer 138 after passing through the deflection roller 180.

As can be seen from FIG. 3, the decorative layer 138 was glued to the plastic profile 122 with the aid of the adhesive layer 136, the metal layer 134 being located on the adhesive layer 136 and the wooden decoration 132 being on the metal layer 134.

In the system 100 of FIG. 1, the plastic profile 122, 124 with the decorative layer 138 is fed to the vacuum coating device 110 after passing through the deflection roller 180. In the vacuum painting device 110 is with Using a vacuum painting process a flame retardant coating layer 200 on the decorative layer 138, that is, on the wood decor 132, applied or sprayed. The flame-retardant lacquer layer 200, the wood decor 132, the metal layer 134 and the adhesive layer 136 form a film structure 210. After painting, the plastic profile 122, 124 with the film structure 210 are transported out of the vacuum painting device 110. In the vacuum painting device 110, the flame-retardant paint layer 200 is sprayed at least on the wood decor 132. However, it is also conceivable that the plastic profile 124 is partially or completely covered with the flame-retardant lacquer layer 200.

As shown in FIG. 1, the vacuum painting device 110 can be arranged directly after the device 105 in the immediate vicinity. However, it is also conceivable that the vacuum painting device 110 is arranged separately.

FIG. 4 shows the plastic profile 124 with the film structure 210 mounted thereon in the process state 205 after the vacuum painting device 110.

The flame-retardant paint layer 200 has a smooth outer surface so that dirt particles are difficult to adhere to. The surface 207 of the flame-retardant lacquer layer 200 also has a high scratch and scratch resistance.

The flame-retardant lacquer layer 200 is colorless and at least partially transparent. The flame-retardant lacquer layer 200 may in particular have different degrees of gloss. With the aid of the metal layer 134, the wood decor 132 appears with a good depth effect three-dimensionally through the flame-retardant lacquer layer 200, without a three-dimensional profile (for example by a tread pressure method) is necessary, at which dirt particles can easily fix.

The flame retardant lacquer layer 200 may be a flame retardant lacquer from Rohm & Haas, Philadelphia, USA. In particular, the flame-retardant lacquer layer 200 may be a Cycon UV topcoat that is colorless and semi-glossy. The flame-retardant lacquer layer 200 may be an acrylic ester having the composition 25 to 50% by weight of 1,6-hexanediol diacrylate, 10 to 25% by weight of pentaerythritol triacrylate, 1 to 3% by weight of 2-hydroxy-2-methyl-1-phenylpropan-1 -on, 10 to 25% by weight of acrylate, less than 1% by weight of alkylphenol alkoxylate and 1 to 3% by weight of hydrocarbon. Preferably, the flame retardant lacquer layer 200 has a flash point greater than 100 ⁰ C and an ignition temperature of 205 ⁰ C.

As can also be seen from FIG. 1, the plastic profile 124 with the film structure 210, after passing through the vacuum painting device 110, is fed to the paint drying device 115, in which the flame-retardant paint layer 200 is dried or cured. As shown in FIG. 1, the paint drying device 115 can be arranged in the immediate vicinity directly after the vacuum coating device 110. However, it is also conceivable that the paint drying device 115 is arranged separately.

According to an alternative embodiment, the plastic profile 120, 122, 124 can also be coated exclusively with the film structure 210 in the device 105 of FIG. In this embodiment, the film 126 rolled up on the unwind roll 140 additionally has the flame-retardant lacquer layer 200 directed inward on the wood decor 132. Accordingly, the peel-off roller 170 removes the film structure 210 containing the flame-retardant lacquer layer 200 from the carrier film 128 and applies it to the plastic profile 124. All

2o other process steps are as described above with respect to FIG.

The flame-retardant lacquer layer 200 is preferably flexible in this embodiment, so that the carrier film 128 with the film structure 210 can pass through the device 105 without breaking at a speed of up to 30 m / min 5. In this case, it is possible to dispense with the vacuum painting device 110 and the paint drying device 115, since the painting and curing of the flame-retardant paint layer 200 on the decorative layer 138 take place even before passing through the device 105. In order to test the properties of the film structure 210 according to the invention, a plurality of plastic profiles 122 having different film structures 210 were coated on an object using the technique according to the invention for applying a decorative layer detachably adhering to a carrier film. The film structures 210 differed in respect of the type of decoration 132. For comparison, 5 plastic profiles 122 were also laminated with a PVC film known from the prior art. The plastic profiles were irradiated with a spotlight in accordance with the American Society for Testing and Materials (ASCM) test standard ASCM D 4803, and the outside temperatures were measured on the exposed side of the plastic profiles and inside the plastic profiles.

The measurement results are shown in the table below. Lines 1 and 3 to 7 show the measurement results (DeMaxZ) of the plastic profiles 122 with the film structures 210 and in lines 2 and 8 the plastic profiles 122 with the laminated PVC film (from other manufacturers).

As can be seen from the table, the plastic profiles 122 with the film structures 210 have a higher temperature difference between outside temperature and inside temperature than the plastic profiles 122 with the laminated PVC film. Consequently, the plastic profiles 122 are more resistant to heat with the film structures 210, whereby the plastic profiles 122 are better protected against deformation even at high solar radiation.
