Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Holzwerkstoffplatte, insbesondere für Fußbodenpaneele, bestehend aus einer Trägerplatte aus einem Holzwerkstoff, wie Span, Sperrholz, OSB, HDF oder MDF, mit einer Oberseite und einer Unterseite.The invention relates to a method for producing a wood-based panel, in particular for floor panels, consisting of a support plate of a wood material, such as chip, plywood, OSB, HDF or MDF, with a top and a bottom.

Fußbodenpaneele als Fußbodenbeläge weisen auf der im verlegten Zustand oberen Fläche ein Dekor und gegebenenfalls eine auf das Dekor angepasste Strukturprägung auf, die einen natürlichen Werkstoff, wie beispielsweise Holz oder Stein imitieren.Floor panels as floor coverings have on the top surface in the laid state a decor and optionally a pattern embossed on the structure imprinting a natural material such as wood or stone imitate.

Als Basisplattenmaterial dienen HDF-, MDF- oder OSB-Platten, deren Dicken in einem Bereich von 2 bis 20 mm, vorzugsweise 5 bis 12 mm liegen und Rohdichten von etwa 880 kg/m3 +/- 10% aufweisen. Auch Platten mit davon abweichenden Parametern, insbesondere niederen Dichten sind für den Einsatz geeignet.The base plate material used are HDF, MDF or OSB plates whose thicknesses are in a range of 2 to 20 mm, preferably 5 to 12 mm and have densities of about 880 kg / m 3 +/- 10%. Even plates with different parameters, in particular lower densities are suitable for use.

Die Dekore für die oberen Flächen der Trägerplatten können dabei auf einer Papierlage oder direkt auf die plattenförmige Basis gedruckt vorliegen. Solche Dekore sind beispielsweise Holz- oder Steinimitationen. Auch Fantasiedekore sind möglich. Diese können sich beispielsweise aus Abwandlungen von natürlichen Werkstoffen ergeben.The decors for the upper surfaces of the carrier plates can be printed on a paper layer or directly on the plate-shaped base. Such decors are for example wood or stone imitations. Fantasy decors are also possible. These can result, for example, from modifications of natural materials.

Bei der Herstellung von Laminatfußböden werden zur Erhöhung der Authentizität neben optisch ansprechenden Dekoren zunehmend Strukturen in die Oberfläche eingeprägt. Dies können einfache Poren bei Holzdekoren sein, aber auch aufwendigere Scraped-Strukturen, die zudem dekorsynchron verlaufen. Zunehmend werden auch Stein- oder Marmorfliesen simuliert, bei denen neben der eigentlichen Oberflächenstruktur auch die dekorsynchrone Prägung der Fugenfüllungslinien von Bedeutung ist.In the production of laminate flooring structures are increasingly embossed into the surface to increase the authenticity in addition to visually appealing decors. These can be simple pores in wood decors, but also more elaborate scraped structures, which also run decorsynchronously. Increasingly, stone or marble tiles are being simulated, in which not only the actual surface structure but also the decor-synchronous embossing of the joint filling lines is of importance.

Fußbodenbeläge werden üblicherweise schwimmend verlegt, wobei eine Verbindung der Paneele untereinander in der Verlegeebene, jedoch nicht mit der darunter befindlichen Bodenlage besteht. Durch Begehen erfolgt eine Anregung des Fußbodens. Es werden hörbare Schallwellen erzeugt. Die Schallwellen sind zum einen in dem Raum hörbar, in dem sich der Fußboden befindet, der so genannte Raum- oder Begehschall. Andererseits wird der Schall in angrenzenden, beispielsweise darunter liegenden Räumen als so genannter Trittschall hörbar.Floor coverings are usually laid floating, with a connection of the panels with each other in the laying level, but not with the underlying bottom layer. By walking a stimulation of the floor takes place. Audible sound waves are generated. The sound waves are audible in the room in which the floor is located, the so-called room or beech sound. On the other hand, the sound in adjacent, for example, underlying rooms as a so-called impact sound audible.

Zur Verringerung der Schallbelastung sind zwischen der Trägerplatte und der Bodenlage schalldämmende und/oder schalldämpfende Schichten vorgesehen. Als solche Schichten kommen vernetzte PE-Matten mit Dicken von 1,0 mm oder 0,3 bis 3 mm dicke gefüllte Schwerfolien, aber auch geschäumte PE- oder PU-Folien zum Einsatz.In order to reduce the sound load, sound-insulating and / or sound-damping layers are provided between the carrier plate and the bottom layer. As such layers crosslinked PE mats with thicknesses of 1.0 mm or 0.3 to 3 mm thick filled heavy foils, but also foamed PE or PU films are used.

Nachteilig bei diesen Schichten ist, dass derartige Matten nur geringe Veränderungen bei der Wahrnehmung des Schalls besitzen. PE-Matten mit Dicken von 1 mm wie auch geschäumte PE- oder PU-Folien auf harten Bodenbelägen reduzieren die Raumschall-Lautstärke kaum, vielmehr verändern sie nur den Klang. Dabei verschiebt sich der dominierende Frequenzbereich solcher Matten und Folien in höhere Frequenzen und lässt den Boden heller klingen. Harte Bodenbeläge mit Schwerfolien im Dickenbereich von 0,3 bis 3 mm werden ebenfalls nicht leiser. Der dominierende Frequenzbereich liegt jedoch eher im tieferen Frequenzbereich.A disadvantage of these layers is that such mats have little change in the perception of sound. PE mats with thicknesses of 1 mm as well as foamed PE or PU films on hard floor coverings hardly reduce the room sound volume, but rather only change the sound. The dominant frequency range of such mats and foils shifts to higher frequencies and makes the ground sound brighter. Hard floor coverings with heavy foils in the Thickness range of 0.3 to 3 mm are also not quieter. However, the dominant frequency range is more in the lower frequency range.

EP-A-1262607 offenbart ein gattungsgemäßer Herstellungsverfahren. EP-A-1262607 discloses a generic manufacturing process.

Der Erfindung liegt die Aufgabe zugrunde, ein vereinfachtes und damit kostengünstiger Verfahren zur Herstellung von Strukturgeprägten Holzwerkstoffplatten bereitzustellen.The invention has for its object to provide a simplified and therefore cost-effective method for the production of structured wood-based panels.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Der mittels dem Verfahren hergestellte Fußbodenbelag weist von unten nach oben gesehen, den folgenden Schichtaufbau auf. Als unterste Schicht wird eine schalldämmende Schicht, in besonderer Ausgestaltung der Erfindung als balance layer wirkend, auf die Trägerplatte aufgetragen, die ein Verziehen der Paneele, das so genannte Schüsseln, verhindert und in besonderer Ausgestaltung gleichzeitig die Verminderung der Tritt- und/oder Raumschallwirkung ermöglicht. Es werden dafür solche Materialien eingesetzt, die für Schalldämpfungen bekannt sind.The floor covering produced by means of the method has the following layer structure from bottom to top. As a lowermost layer, a sound-absorbing layer, acting in a particular embodiment of the invention as a balance layer, applied to the support plate, which prevents warping of the panels, the so-called bowls and at the same time allows the reduction of the impact and / or room sound effect , There are used for such materials, which are known for soundproofing.

Die folgende Trägerplatte aus einem Holzwerkstoff, wie Span, Sperrholz, OSB, HDF oder MDF, trägt auf der Oberseite ein Dekor bestehend aus mindestens einer Kunststoffschicht und einem Dekorpapier. Das Dekorpapier weist eine Strukturprägung auf. Auf das Dekor wird eine versiegelnde Lackschicht, die oberflächennah abriebfeste Partikel, wie Korund enthalten kann, und wiederum in einer anderen besonderen Ausgestaltung eine weitere Strukturprägung besitzt, aufgetragen.The following carrier plate made of a wood material, such as chip, plywood, OSB, HDF or MDF, carries on the top of a decor consisting of at least one plastic layer and a decorative paper. The decorative paper has a textured embossing. On the decor is a sealing lacquer layer, which may contain surface near abrasion resistant particles, such as corundum, and in turn has another structure embossing in another particular embodiment applied.

Das auf die Oberfläche der Trägerplatte aufzutragende Dekor besteht aus einem Folienpaket aus wenigstens einer elastischen und thermoplastisch verformbaren Kunststoffschicht und einem Dekorpapier. Das Folienpaket wird durch oberflächiges Ausbringen eines flüssigen Kunststoffes zu einer Schicht mit einer Dicke von 0,2 bis 2,5 mm bei einer Oberflächentemperatur von 130 bis 200 °C und gleichzeitigem Auflegen eines Dekorpapiers auf die Kunststoffschicht und Verbinden beider unter Ausnutzung der in der Kunststoffschicht vorhandenen Wärmeenergie erhalten. Als Kunststoffe kommen EVA, PP, PE, PET, PVC, Acrylate Polyolefine, Polyester und Wachse in Frage. Thermoplastische Polyurethane (TPU) werden jedoch nicht verwendet. Aber auch andere Kunststoffe mit vergleichbaren Eigenschaften sind einsetzbar. Ebenso sind Kombinationen der vorgenannten Kunststoffe einsetzbar. Der zum Einsatz gelangende Kunststoff richtet sich nach den gewünschten Eigenschaften des fertigen Paneels. So sind PVC-Kunststoffe preiswert. EVA-Kunststoffe sind preiswert, elastisch und plastisch, während PP-Kunststoffe elastisch, hart und zäh sind. Acrylat-Kunststoffe sind UV-Licht aushärtend und PET-Kunststoffe sind kostengünstig herstellbar. Wachse weisen plastische Eigenschaften auf.The decor to be applied to the surface of the carrier plate consists of a foil packet of at least one elastic and thermoplastically deformable plastic layer and a decorative paper. The film package is made by surface application of a liquid plastic to a layer having a thickness of 0.2 to 2.5 mm at a surface temperature of 130 to 200 ° C and simultaneously applying a decor paper on the plastic layer and connecting both taking advantage of in the plastic layer obtained existing thermal energy. Suitable plastics are EVA, PP, PE, PET, PVC, acrylates, polyolefins, polyesters and waxes. However, thermoplastic polyurethanes (TPU) are not used. But other plastics with comparable properties can be used. Likewise, combinations of the aforementioned plastics can be used. The plastic used depends on the desired properties of the finished panel. So PVC plastics are cheap. EVA plastics are inexpensive, elastic and plastic, while PP plastics are elastic, hard and tough. Acrylic plastics are UV curing and PET plastics are inexpensive to produce. Waxes have plastic properties.

Die Kunststoffschicht kann auch aus mehreren Schichten aufgebaut sein, wobei nur ein Kunststoff aber auch unterschiedliche Kunststoffe nacheinander übereinander großflächig ausgebracht werden können.The plastic layer may also be composed of several layers, wherein only one plastic but also different plastics can be sequentially superimposed over a large area.

Gemäß der Erfindung wird das Folienpaket mit einer Strukturprägung, vor dem Aufbringen auf die Holzfaserplatte, versehen. Das wird durch eine strukturierte Prägewalze erreicht. Alternativ ist die Verwendung eines Strukturpapiers, das zwischen dem Folienpaket und einer glatten Prägewalze mitgeführt wird und wieder verwendbar ist, möglich. Auch hier werden die plastischen Eigenschaften des noch unter Wärme befindlichen Kunststoffs ausgenutzt und die Strukturierung in den kontinuierlichen Verfahrensablauf eingefügt. Die Strukturprägung weist eine Tiefe größer als 100, vorzugsweise 200 bis 400 ym auf. In einer besonderen Ausgestaltung kann die Strukturprägung synchron zum Dekor verlaufend ausgeführt sein.According to the invention, the film package is provided with a pattern embossing, before application to the wood fiber board. This is achieved by a structured embossing roller. Alternatively, it is possible to use a textured paper which is carried between the film pack and a smooth embossing roll and is reusable. Again, the plastic ones Properties of the still under heat plastic used and added the structuring in the continuous process flow. The structure embossing has a depth greater than 100, preferably 200 to 400 ym. In a particular embodiment, the structure embossing can be executed running synchronously to the decor.

Als Trägerplatte für das Folienpaket sind Platten mit einer Länge von 2.800 bis 5.600 mm und einer Breite von 1000 bis 2200 mm bestens geeignet.As a carrier plate for the foil package plates with a length of 2,800 to 5,600 mm and a width of 1000 to 2200 mm are ideally suited.

Das Folienpaket wird auf die Trägerplatte, beispielsweise unter Verwendung eines wasserlöslichen PU-Klebstoffes aufgebracht. Nach dem Aufbringen des Folienpaketes wird eine das Dekor versiegelnde Lackschicht aufgetragen, wofür beispielsweise strahlenhärtbare Acrylatlacke verwendbar sind. Die Acrylatlacke können durch andere Lacke mit vergleichbaren Eigenschaften ausgetauscht werden.The film package is applied to the carrier plate, for example using a water-soluble PU adhesive. After application of the film package, a decor-sealing lacquer layer is applied, for which, for example, radiation-curable acrylate lacquers can be used. The acrylate coatings can be replaced by other coatings with comparable properties.

Zur Erreichung einer hohen Abriebfestigkeit mit Werten von AC1 bis AC5 in Anlehnung an die Normen EN 13329, EN 15468, EN 14978 und einem übermäßigen Verschleiß vorzubeugen, werden wenigstens in oberflächennahen Bereichen der Lackschicht abriebfeste Partikel, beispielsweise Korundkörner eingebettet.In order to achieve a high abrasion resistance with values of AC1 to AC5 based on the standards EN 13329, EN 15468, EN 14978 and to prevent excessive wear, abrasion-resistant particles, for example corundum grains are embedded at least in near-surface areas of the paint layer.

Das Verfahren gemäß der Erfindung weist die Merkmale des Anspruche 1 auf.The method according to the invention comprises the features of claim 1.

Das Auftragen einer Lackschicht kann nach dem Aufkleben des Folienpaketes auf die Holzfaserplatte erfolgen, bevorzugt aber beim Herstellen des Folienpaketes.The application of a lacquer layer can be carried out after the gluing of the film package on the wood fiber board, but preferably during the production of the film package.

Zur Verbesserung der Abriebfestigkeit können vorzugsweise oberflächennah Korundpartikel oder Partikel mit vergleichbaren Eigenschaften in diese Verschleißschutzschicht eingefügt werden.To improve the abrasion resistance, corundum particles or particles with comparable properties can preferably be incorporated into this wear protection layer near the surface.

Werden derart hergestellte Platten zu Fußbodenpaneelen in dem zum Dekor passenden Format zersägt, werden sie mit Profilausfräsungen für Klickverbindungen versehen. Durch das aufgebrachte Folienpaket auf die Trägerplatte lassen sich tief strukturierte Dekore ausbilden. Gleichzeitig wird durch den verwendeten Kunststoff ein wärmeres, weicheres Begehgefühl erzeugt. Im Zusammenhang mit dem Material für die balance layer wird eine geringere Neigung für die Erzeugung eines Raum- und/oder Trittschalls erreicht.If boards produced in this way are sawed into floor panels in the format suitable for the decoration, they are provided with profile cutouts for click connections. The applied film package on the carrier plate makes it possible to form deeply textured decors. At the same time a warmer, softer Begehgefühl is generated by the plastic used. In connection with the material for the balance layer, a lower tendency for the generation of a room and / or impact sound is achieved.

Beim Herstellen des Folienpaketes, also dem direkten Bedrucken der Kunststoffschicht mit einem Dekor oder dem Auflegen eines bedruckten Papiers und Beschichten mit einem Lack werden die sonst beim Aufbringen der einzelnen Schichten auf die Holzfaserplatte sich aufbauenden Spannungen weitgehend abgebaut.When producing the film package, ie the direct printing of the plastic layer with a decor or the laying of a printed paper and coating with a lacquer which otherwise build up when applying the individual layers on the wood fiber board tensions are largely degraded.

Durch das Folienpaket werden also kaum größere Spannungen in die Trägerplatte eingebracht und damit ein Schüsseln weitgehend vermieden. Eine balance layer ist nicht notwendig. Ebenso lassen sich die Dicken der zum Einsatz gelangenden Trägerplatten minimieren.The film package thus hardly larger voltages are introduced into the carrier plate and thus a bowl largely avoided. A balance layer is not necessary. Likewise, the thicknesses of the carrier plates used can be minimized.

Bei der Auftrennung in Paneele wird eine gute Kantendichtheit gegenüber Wasser erreicht, da sich durch das zum Einsatz gelangende Folienpaket elastische Fügekanten ergeben.When separating into panels, a good edge sealing against water is achieved, since elastic joining edges result from the film package used.

Ein weiterer Vorteil ergibt sich beim Einsatz des Folienpaketes dadurch, dass man den verwendeten Kunststoff mit Zusatzstoffen versehen kann, die der Dekorbeschichtung besondere Eigenschaften, z. B. den Strom ableitend verleihen.Another advantage arises when using the film package in that you can provide the plastic used with additives that the decor coating special properties, eg. B. lend the current.
