DESCRIPTION

Laminate material to cover a material derived from wood in the form of a plate

The invention relates to a laminated material for covering a material derived from wood in the form of a plate.

There is a need for high-quality coated wood-based slab materials, for example slab wood-based materials with an extra-gloss, specular or super-matte surface or with a surface, which does not show any fingerprints. fingerprint, which is guaranteed with an anti-fingerprint surface.

In the case of surface coatings made of materials derived from wood, a distinction is made between laminate surfaces and coated surfaces. Laminate surfaces are generated in a press, which chemically hardens a layer of synthetic resin, often in the form of a paper impregnated with synthetic resin, on the surface of the wood-derived material under the action of pressure and temperature. The coating takes place by fixing a sheet, which is optionally coated, or an adhesive laminated material on the surface of a material derived from wood in the form of a plate.

In HOB Holzbearbeitung, edited by AGT Verlag Thum GmbH, Ludwigsburg, edition 9 of 2013, pages 42 to 46 “Von Supermatt bis Hochglanz”, Jens Fandrey, different procedures are described for generating qualitatively high-quality surfaces on wood-derived materials in plate shape, among others also the coating of the plate made of material derived from wood with a sheet, which is coated with varnish, the surface being able to be a super matt, extra-gloss varnish or also be provided with an anti-fingerprint coating. Document EP 2146805 B1 describes the machining of a surface of varnish, which is applied on a plate of material derived from wood.

A disadvantage of applying a sheet with a high quality surface to a wood-derived material surface in the form of a plate is that the sheet is extremely flexible and can only be applied with great effort without wrinkles on the surface of the derived material plate. From the wood. Therefore, there is a goal to provide an easier to process material with a high quality surface to hide a plate-shaped wood-derived material.

EP 0013267 A1, WO 03/008708 A1 and WO 2009/000769 A1 describe the production of papers or prepregs, which can be varnished. Document WO 2013/167 533 A1 describes the production of a decorative paper, which is pressed onto a plate of material derived from wood, a structure being able to be incorporated into the paper during the pressure. Document WO 2015/058 820 A1 describes a product composed of a plastic fabric or a plastic plate, on which a paper is applied. A covering layer of the composite product can be provided with a pattern. That is, the last two documents mentioned do not refer to a laminated material.

The products presented in these documents offer a simple surface, which is not adapted to special aesthetic or technical requirements. Therefore, there is an object to provide a surface or a method for producing a surface, which can be easily adapted to special aesthetic or technical requirements.

This disadvantage is solved with the laminated material according to claim 1.

The laminated material according to the invention is a paper web impregnated with synthetic resin, which has a layer of varnish. The varnish layer is applied to one side of the laminate, which is referred to below as the top side of the laminate. The opposite side of the laminate, the underside, is supported after application on a wood-based material plate on the surface of the wood-based material plate. The underside of the laminate is preferably glued onto the surface of the wood-based material board. The laminated material can be produced from one or more paper webs, often the laminated material is made up of multilayer paper webs, usually two to four layers.

As sheet material is used according to the invention a paper web of a layer or layers, impregnated with synthetic resin, which are also called laminates continuous pressure laminate (CPL, Continuous Pressed Laminate) or high pressure laminates (HPL, High Pressure Laminate). CPL and HPL can have a single web of paper, which was impregnated with synthetic resin, which was then cured. However, CPL and HPL usually consist of several layers of paper, in most cases of different quality and with different weights. Normally - from the bottom side to the top side of the laminated material - a firm kraft paper is used as the backing paper, on which a thin, dyed or often printed decorative paper is arranged. The decorative paper can be covered with a very thin paper, the overlay paper, which appears transparent and therefore allows the decoration paper to be seen. In particular when different synthetic resins or synthetic resin blends are used to impregnate the different papers, a so-called base paper can be inserted between the kraft paper and the decorative paper. Each of these papers is impregnated with synthetic resin. The papers are brought together after impregnation with synthetic resin to give a laminated material and compressed at temperatures of approximately 150 ° C to 180 ° C either continuously in a double belt press (CPL) or in individual sheets in a plate press to produce a laminated material (HPL), in which one or more paper webs are impregnated with hardened plastic.

The varnish is applied in liquid form on the upper side of the laminate, preferably in an amount of between 5 g / m2 and 300 g / m2, usually in an amount of from 25 g / m2 to 70 g / m2, especially preferably between 30 g / m2 and 60 g / m2 when the surface must be extra glossy or with specular gloss. A varnish application that is as minimal as possible is pursued, to save material. On the other hand, sufficient varnish must be applied to obtain a smooth surface and to allow structures to be inserted into the varnish if necessary. If flat structures, i.e. depressions, are to be stamped on the surface only or with a depth of no more than 20 µm in the varnish layer, or else to generate super matte or anti-fingerprint structures, then a varnish layer may also suffice thin. However, deeper structures or depressions of up to 150 µm must be stamped into the surface, then it may be necessary to apply a thicker layer of varnish or several thinner varnish layers with a total thickness of up to 300 µm. In this connection, the varnish layers can be cured wet-on-wet or individually, however, the structures can preferably be stamped into the uncured or not yet fully cured varnish. It is also possible to superimpose flat structures with depressions of up to 20 µm on the surface with deeper structures, so that, for example, a super-mat surface is additionally provided with depressions of up to 150 µm, to generate profiled fantasy decorations or natural decorations with a super matt surface or an anti-fingerprint surface, which have both a color decoration in most cases and a three-dimensional structure on the surface in most cases. A special advantage is that neither the surface of the laminated material nor the varnish layer has to be polished before the varnish layer is machined. That is, the laminated material according to the invention with a varnish layer can be produced with extremely low effort with an extremely high-quality surface of the varnish layer at the same time.

Varnishes that cure with light and UV radiation are preferably used, in most cases based on acrylate. These can usually be pure acrylates or modified acrylates, for example acrylates modified with urethanes, epoxides, polyesters or silicon compounds. The varnish is applied in liquid form. The varnishes can be applied in any way, preferably by lamination, but also by pouring or applying with scrapers. Preferably, the surface of the varnish layer after the liquid varnish has hardened is designed as a high-gloss surface, in particular with a specular or mirror luster (with a gloss degree of 90 GE or more) or as a super-matt surface (with a degree of 15 GE maximum brightness) or also as an anti-fingerprint surface. The gloss degrees are determined according to DIN EN ISO 2813, measured according to the degree of gloss of the surface with a measuring angle of 20 ° (extra-gloss), 60 ° (from glossy to silk-matte) or 85 ° ( mate).

By applying the varnish, an improved laminate material with a high-quality surface is generated. The material thickness of the improved laminate is 0.2mm to 2mm, typically 0.5mm to 1.5mm. This laminated material can still be rolled up despite the varnish layer applied. Thus, the varnished laminate according to the invention is also suitable for endless processing.

The varnish, which is applied according to the invention on the upper side of the laminate, adheres well to the cured synthetic resin, in particular to an aminoplast surface. In spite of this, it is not ruled out that a layer of adhesion agent is applied on the synthetic resin, in order to bond the varnish layer particularly firmly to the synthetic resin.

As adhesion agent, for example silane compounds can be used.

The role of the laminate, which is impregnated with synthetic resin, generally consists of cellulose fibers. In general, it can be made up of natural and synthetic fibers. Typical suitable fibers are, in addition to cellulose fibers, also mineral fibers, glass fibers, viscose fibers, carbon fibers, metal fibers, but also plastic fibers, in particular aramid fibers. A paper can also consist of a mixture of fibers, in particular a mixture of natural and synthetic fibers. The fibers are selected based on technical but also economic points of view. Thus, cellulose fibers are inexpensive and generally of sufficient strength. Other fibers are more robust, for example aramid fibers, are more conductive (carbon and metallic fibers) or are even more transparent than cellulose fibers (plastic fibers, glass fibers, mineral fibers), so that even when larger amounts of fiber are used, a transparent appearance remains. The paper preferably has a sheet weight of from 10 g / m2 to 360 g / m2, aiming to select a paper that is as light as possible, for example from 20 g / m2 to 40 g / m2, to save material.

The laminated material can have a single paper web, which is impregnated with synthetic resin. However, in most cases the laminate will have two or more webs of paper. In general, a support paper is used in most cases, which must have the highest possible strength. A decorative paper must be able to either be dyed and / or printed but with as little material usage as possible. An overlay paper should be as transparent as possible, a base paper used in some cases that saves as much material as possible. According to a further preferred embodiment, the decorative paper has a decoration on its upper side, which in most cases is produced as a color print. The decoration can be a fantasy decoration or imitate a wooden or stone surface. The decoration can consist for example of a primer and one or more color applications, which are applied in sections on the primer and whose color differs from the color of the primer.

Synthetic resin or synthetic resin blends may contain urea particles, for example to improve the scratch resistance of the surface. The paper or synthetic resin can also contain conductive elements, for example fibers or particles, which improve the conductivity of the coating. If an overlay is used, then urea particles are added, in most cases corundum, but also salts to the synthetic resin, thereby impregnating the overlay. Conductive fibers or particles can also be added to the synthetic resin, with which the backing paper or the decorative paper or the base layer is impregnated.

The paper according to the invention is impregnated with a synthetic resin. Typical suitable synthetic resins are melamine resin, urea-formaldehyde resin, and phenol-formaldehyde resin. However, it is also possible to use dispersions of polyurethane, water glass or silane compounds, which in connection with this invention are also called synthetic resins. Mixtures of these resins can also be used. It is also possible to impregnate the paper web to be impregnated first with, for example, urea-formaldehyde resin and then to apply another synthetic resin, for example melamine resin, on one or both sides. The synthetic resin or the mixture of synthetic resins can be used in an amount, which has the paper surface fibers and synthetic resin. However, it is also possible that the paper or the paper fibers are completely embedded in the paper, so that the surface of the paper impregnated with synthetic resin consists entirely of synthetic resin. Typically, the use of synthetic resin is from about 80% by weight to 100% by weight of the sheet weight of the paper used.

The laminated material according to the invention can be produced as a continuous web by means of a double belt press (CPL) or in an arcuate shape in a plate press (HPL). Both procedures are known and common in the industry. The laminate material, both CPL and HPL, is impregnated with a synthetic resin, which is hardened. Thus, the paper according to the invention differs from paper, which is used to laminate surfaces of materials derived from wood, and in which the synthetic resin is only dry, but not hardened. The finished laminate material has a flat, dense and hard surface, which can be applied over wood-based materials without additional coating. The surface of the laminated material is simply comparable to a polished varnished surface, which is prepared for high-gloss varnishing, without however complex polishing operations having to be carried out. The invention relates to a further treatment of such a laminate, in particular a refining, which creates a surface with a high quality appearance.

The laminate material is fixed according to an advantageous development on the surface of a material derived from wood in the form of a plate. Materials derived in the typical way are chipboards, fibreboards, plywood boards, joinery boards, but also solid wood boards. In particular, plate-shaped wood-derived materials, which are used in the construction of furniture or in high-quality internal lining, can be covered with the laminate material according to the invention. Since the synthetic resin is already hardened, the laminate material is secured by gluing onto the wood-based material surface. As the adhesive, a hot melt adhesive, for example a polyurethane adhesive or a polyvinyl acetate adhesive, can be used. The adhesive can either be applied to the surface of wood-derived material or the adhesive can be applied to the underside of the synthetic resin impregnated paper. The gluing or coating of wood-based materials on the surface of wood-based materials in the form of plates is state of the art.

The laminated material according to the invention offers numerous advantages. On the one hand, an existing and technically cured product can be easily fine-tuned. On the other hand, the entire bandwidth of the decorations can be offered with additionally improved surfaces, in particular extra-gloss, with specular or super-matt gloss, alternatively also with anti-fingerprint surfaces. Furthermore, an improved product is made available compared to polymer films, because the laminated material according to the invention has improved flexural strength and toughness. In this way, the laminated material according to the invention can be processed, on the one hand, more easily, because both individual sheets of the laminated material and a rolled laminated material can be laid and positioned better than a soft, flexible sheet. The stiffer, harder laminate material according to the invention can also better compensate for irregularities in the surface of the wood-derived material, without this leading to a deformation of the upper side of the laminate, so that in particular on quality surfaces very high gloss, in particular extra-gloss and specular gloss, irregularities on the surface of the work material to be coated do not impair the high-quality optical impression of the laminate surface and do not lead to waste. Finally, the surface of the varnished laminate is also stronger than the surface of a varnished polymeric sheet. With the varnished laminate according to the invention it is possible in particular in a very simple way to generate not only extra-glossy surfaces but also surfaces with a mirror gloss. Specular gloss surfaces reflect an object in front of the surface particularly precisely and with sharp edges. To generate surfaces with a specular gloss, it is presumably necessary to apply the varnish layer on a particularly flat substrate, which can be produced with a laminated material, in particular with a laminated material with a glossy or extra-glossy surface, in a simple way depending on the production.

A process for producing a laminated material to cover a wood-derived material in the form of a plate may have the steps of: applying synthetic resin on a paper web, hardening the synthetic resin, applying a varnish, machining the varnish surface and hardening the varnish.

The application of synthetic resin onto a paper web (resin impregnation) leads to impregnation of the paper web, because the usually liquid synthetic resin passes through the paper web. The synthetic resin, which impregnates the paper web, then hardens, i.e. it is triggered, for example under the influence of temperature and / or pressure, for example in a double web press or in a plate press, a reaction chemistry, whereby the synthetic resin reacts completely to give an inert mass, which is no longer reactive. Upstream of the hardening there may be drying of the synthetic resin. The hardened paper, impregnated with synthetic resin, exhibits a significantly higher stiffness than the non-impregnated paper web and also a higher stiffness than a sheet, which is used for coating materials derived from wood in the form of a plate. Despite this, the laminate web can be rolled up without problems. It is also very suitable for refining and endless manufacturing processes.

A liquid varnish is then applied to the laminated material. The varnish is advantageously applied over the entire surface of the paper web. The side of the paper web coated with varnish is called the top side. The varnish layer is applied from liquid varnish with a layer thickness that is as uniform as possible on laminated material. Optionally, a leveling of the varnish layer can take place in an intermediate stage.

The varnish surface is machined, preferably before it is cured. Machining takes place in the simplest case by means of a structure former, a structured material web. In contrast to the previously described equalization of the varnish layer, by machining the varnish surface in a targeted manner, the surface, ie the boundary surface of the varnish layer, is configured with respect to the environment. It is provided, for example, with a strip of structured material with a matt surface, if necessary super matt or with an anti-fingerprint surface. The strip of material closes the surface of the varnish layer from the surroundings; that is, it also keeps oxygen away. The machining of the surface of the varnish layer can be called in this embodiment inert process, because it takes place with exclusion of oxygen. The varnish hardens after application, in particular during or directly after machining, preferably by UV radiation per se known or by electron beam curing.

Preferably, curing of the varnish layer takes place during machining of the varnish surface. Thus, the curing of the varnish layer can preferably take place during the action of the material web, for example according to a first alternative a curing device can be arranged, usually an electron beam or UV unit known per se , opposite or directly after the material web. When the machining of the varnish surface takes place with a transparent laminate, the curing device can then be arranged on the same side as the laminate. Otherwise, the curing device according to a second alternative is arranged on the opposite side of the laminate. In this case, the band of material is conveniently transparent. A material web of a polymer, optionally as a fiber-reinforced polymer web for machining varnish surfaces, is disclosed, for example, in EP 2 146805 B1.

The material band is structured. It is preferably transparent. It consists according to the invention of a polymeric foil, optionally fiber-reinforced. A band of material can be intended for a single use, but it can also be used multiple times. The web of material will be available for example from a roller, as a rule as an endless web of material, but it is also possible to make the web of sheet material available. By placing and possibly pressing the material web on the surface of the liquid varnish layer, this surface is machined. It provides a structure applied to the surface of the material strip as a negative structure on the surface of the firstly still liquid varnish layer, this structure of the material strip then being shown by hardening the liquid varnish to give a solid varnish layer as a shaped and fixed surface. That is to say, the hardened, machined surface of the varnish shows, according to the invention, a negative of the surface of the strip of material. Within the framework of the invention, the material strip can advantageously remain as a single-use material strip on the varnish layer and thus serve as protection against damage to the varnish layer during storage and transport. Especially in the case of extra-glossy or specular gloss surfaces this measure proves to be particularly valuable. Since the material strip is nevertheless applied for surface machining on the varnish layer, this measure opens up additional use without additional costs or technical means.

The application of a layer of varnish on a laminated material causes a special depth action of the varnished surface to be achieved. The synthetic resin, in particular when it is smoothed after impregnation of the paper, for example by means of the presses and thus also compacts as a rule, offers the varnish layer a substrate, which is optically present as a continuation of the varnish layer and thus provides a special depth action of the varnish layer. This gives high-gloss varnish surfaces in particular a high-quality appearance. Furthermore, the flat surface of the laminated material, which takes place by pressing the laminated material during hardening, enables the production of specular surfaces, which roughly comparable to the precision of a mirror reflect sharply outlined objects in front of the surface, ie they guarantee a mostly parallel beam path even after reflection.

Compared to known varnish surfaces for materials derived from wood, the solution according to the invention requires fewer materials and is thus environmentally friendly. You can prepare with known production facilities and cheap, although the surface has a very high quality appearance.

The details of the invention will be explained by means of figures. They show:

Figure 1, a schematic representation of a CPL production facility with a device for varnishing and machining the varnish layer.

Figure 2, a laminated material with a varnish layer.

Figure 1 shows a continuous installation 1, in which the laminated material 2 in immediately successive work operations is not produced until impregnation with liquid synthetic resin 3 and subsequent hardening and is then provided on one side with a layer of varnish 4. The same process steps can also take place in separate plants, firstly impregnation with synthetic resin 3 and curing of the synthetic resin, that is to say the production of the laminate material known per se, in this case a CPL, but alternatively also a high pressure laminate (HPL) and then, separately therefrom, the essential application, machining and curing according to the invention of the varnish layer 4.

The installation, shown in Figure 1, shows from left to right in the production direction a roll 5 with backing paper 6 with a sheet weight of 80 g / m2, which is unrolled and guided through a roll 7 by a bath 8, in which liquid melamine resin 3 is present as a synthetic resin. The support paper 6 captures 100% of 80 g / m2 of melamine resin. The backing paper 6 is optionally printed with a decoration, for example with a wooden decoration or with a fancy decoration. The melamine resin 3 penetrates the backing paper 6, so that a laminate 2 is generated. This operation is also called resin impregnation. Not all the melamine resin can be absorbed into the backing paper 6, so on both sides the surface of the synthetic resin-coated paper 2 consists exclusively of melamine resin 3. If a lesser amount of synthetic resin is used, the surface of the Paper impregnated with synthetic resin can also consist of a mixture of fibers and synthetic resin. The laminated material is compressed in the double belt press 9, which is schematically represented with the upper branch 10 and the lower branch 11, at 160 ° C in about 20 seconds to give a laminated material. Optionally, the double band press may contain means for cooling the laminate 2, which more rapidly cool the hardened laminate. Also optionally, a drying device can be arranged between the bath 8 and the double-band press 9, which removes the excess liquid from the synthetic resin. The laminated material 2 according to Figure 1 is transparent.

Alternatively (not shown in this case) a multilayer laminated material can be produced, in which a 90 g / m2 kraft paper (produced from especially strong kraft pulp) is impregnated with phenolformaldehyde resin (80% resin based on a sheet weight of 90 g / m2 kraft paper) and with a base paper of 50 g / m2 impregnated with melamine-formaldehyde resin (80% synthetic resin based on a sheet weight of base paper of 50 g / m2), with a decorative paper of 65 g / m2 provided with a primer and a printed color decoration, which is impregnated with melamine resin (90% of synthetic resin with respect to a weight of 65 g / m2 decorative paper sheet) and with a 15 g / m2 overlay paper, which is impregnated with melamine resin (100% synthetic resin based on a 15 g overlay paper sheet weight / m2), are assembled into a cylinder arrangement and either compressed as an endless belt in a double belt press to give a multilayer CPL laminate or compress as lies in a plate press to give an HPL laminate. These procedures are per se known from the state of the art.

The rolled stock is not only extremely smooth and hard after leaving the double belt or plate press, but also especially flat. It can also be configured extra-bright. It is therefore exceptionally suitable for coating with a uniform layer of varnish.

The impregnation with synthetic resin is followed, either directly or as a separate machining unit, by the application of a layer of varnish 4 on an upper side of the laminate 2. In the case of a multilayer laminate, the layer of varnish is applied on the upper side, showing a decorative paper or an overlay paper. The laminated material 2 is passed through a roll arrangement 12, which applies a 40 g / m2 layer of liquid varnish. Since the laminate 2 is very smooth and flat, the liquid varnish layer 4 can also be applied very evenly and flat on its upper side. An acrylic-based varnish is applied, which is cured by means of UV light. Modified acrylic varnishes are also often used, for example acrylic varnishes modified with urethane, epoxy or silicon compounds. The person skilled in the art is familiar with which acrylic varnishes are available, and with few indicative trials finds the suitable varnishes.

Following the roll arrangement 12, the surface 13 of the varnish layer 4 is machined, more precisely the still liquid varnish layer 4. In the embodiment according to FIG. 1 this takes place by applying a strip of material without end 16, which is applied in the width of the laminated material on the surface 13 of the still liquid varnish layer by unwinding from a reserve roll 14. The web of material 16 is after passing through a pressure roller 15 without bubbles on the surface 13 of the varnish layer 4, so that the surface 13 of the varnish layer is completely flat and smooth, in particular it is free from unwanted marks. In addition, the surface 13 of the varnish layer 4 is not exposed to oxygen in the air in this way, so this process step can also be called inert process.

While the material web 16 rests on the surface 13 of the varnish layer 4, UV lamps 17 act on the varnish layer 4 through the transparent laminate 2 and harden it. In this regard, the varnish layer 4 is cured from the laminate 2 to the surface 13 of the varnish layer and is closed during curing by the material strip 16, with the consequence that it takes place up to the surface 13, that is, up to the boundary surface of the varnish layer 4 for the material web, a uniform crosslinking or curing. This produces a surface 13 with a gloss degree of 90 GE or more. Alternatively, the UV lamps 17 can also be arranged on the same side as the pressure roller 15.

After the varnish layer 4 has cured, the laminate 2 provided with the varnish layer 4 is smooth and is provided with a mirror-gloss surface 13.

The endless material web 16 after the varnish layer 4 has hardened can optionally or be removed immediately and for example used again. Alternatively, the material strip 16 can remain on the hardened varnish layer 4 and protect the surface 13 of the varnish layer 4, if necessary through coating beyond a plate of wood-derived material until the use of the plate made of material derived from wood covered with the varnished laminate material.

Figure 2 shows a laminated material 2 according to Figure 1 with a fiber paper web 19, which is impregnated with synthetic resin, in this case with melamine resin 3. The melamine resin 3 completely passes through the paper web with the fibers 19, so that the surface of the paper web is formed on both sides completely by melamine resin 3. In other words, the melamine resin 3 protrudes on both sides of the paper web. On the one hand, on the upper side 20 of the laminate 2 is applied a varnish layer 4, which has an extremely smooth surface 13 and a specular gloss surface with a gloss degree of 90 GE or more. The underside 21 of the laminate 2 can optionally be provided with an adhesive layer (not shown in this case). When the laminate 2 is not immediately applied to a wood-based material surface, then it is recommended to cover such an adhesive layer with a release paper. The varnished laminate, optionally provided with an adhesive layer and release paper, can be rolled up for later use. As an alternative to rolling, the varnished laminate material impregnated with synthetic resin can also be cut into sheets, stacked and further processed.

The application of the varnished laminate 2 according to the invention on the surface of a material derived from wood in the form of a plate takes place in the same way as with the unvarnished laminate, preferably by adhesion. Due to the hardness of the laminated material, the surface irregularities of the wood-derived material or also polishing residues (dust grains) are not transferred as in the case of a coating with a soft sheet, but the coating allows them to be produce a flawless surface with much lower rejection than a sheet coating. Alternatively, the surface of wood-derived material to be coated with the laminate according to the invention requires simpler preparation, because the laminate material according to the invention compensates for small irregularities essentially better.

A surface of material derived from wood covered with the laminate material 2 described above has a surface with a specular gloss, alternatively extra-glossy, super matt or equipped with an anti-fingerprint structure with a special depth action, because the varnish and the synthetic resin are joined together such that the generally particularly transparent coating is generated on a very flat substrate, which has an extremely high value appearance.

If a transparent laminate is used, for example of a single, thin paper layer, which is impregnated with melamine resin, with a varnish layer according to the invention applied thereon, then such a laminate can be coated on a surface of material derived from wood, provided with a decoration, for example printed. Due to the high transparency of the varnished laminate material, the decoration acts on the surface of material derived from wood with practically no optical limitation.
