Beläge aus Kork, insbesondere Korkböden, erfreuen sich immer größerer Beliebtheit, vorwiegend im privaten Wohnbereich. Korkboden ist pflegeleicht, elastisch sowie gelenkschonend und erzeugt ein gesundes Raumklima mit wohltuender Fußwärme. Zudem sind Korkböden angenehm leise.Cork flooring, especially cork flooring, is enjoying increasing popularity, predominantly in private homes. Cork flooring is easy to care for, elastic and gentle on the joints and creates a healthy indoor climate with soothing foot warmth. In addition, cork floors are pleasantly quiet.

Ein mehrschichtiger Korkboden geht beispielsweise aus der EP 0 611 408 B1 hervor. Auch die DE 10 2005 006 532 A1 beschreibt ein Paneel bestehend aus mehreren Schichten, wobei die obere sichtbare Nutzschicht auch aus Kork bestehen kann. Durch die DE 102 01 087 A1 zählt ein elastischer Bodenbelag zum Stand der Technik, bestehend aus miteinander verbindbaren mehrschichtigen Bodenplatten mit wenigstens einer oberen Schicht aus Linoleum, Kunststoff oder Kork.A multilayer cork floor, for example, goes from the EP 0 611 408 B1 out. Also the DE 10 2005 006 532 A1 describes a panel consisting of several layers, wherein the upper visible wear layer may also consist of cork. By the DE 102 01 087 A1 includes an elastic flooring to the prior art, consisting of interconnectable multilayer floor panels with at least one upper layer of linoleum, plastic or cork.

Aus der DE 10 2006 008 147 A1 geht ein Paneelelement für einen Fußboden-, Wand- oder Deckenbelag hervor, wobei das Paneelelement ein Spritzteil ist, welches aus einem Gemisch ausgebildet ist, der einen nachwachsenden Rohstoff enthält sowie ein den nachwachsenden Rohstoff verbindendes Material und gegebenenfalls Hilfs- und Zusatzstoffe. Als nachwachsender Rohstoff zur Ausbildung des Spritzteils wird unter anderem Kork vorgeschlagen.From the DE 10 2006 008 147 A1 goes out a panel element for a floor, wall or ceiling covering, wherein the panel member is a molded part, which is formed from a mixture containing a renewable raw material and a material combining the renewable raw material and optionally auxiliaries and additives.

Die EP 0 442 863 A2 beschreibt eine Paneele aus einem wärme- und schallisolierenden Material, beispielsweise agglomeriertem Kork. Die Oberfläche der Paneele ist graviert, beispielsweise um der Paneele eine Maueroptik zu verleihen, und mit einer Wasserschutzfarbe angestrichen.The EP 0 442 863 A2 describes a panel made of a heat and sound insulating material, such as agglomerated cork. The surface of the panels is engraved, for example, to give the panels a wall look, and painted with a water-resistant paint.

Zum technologischen Hintergrund zählt durch die EP 0 094 524 A2 eine Korknoppenplatte, wobei zwischen zwei Schichten aus einer vulkanisierbaren Mischung aus einem Elastomer und Korkmehl ein Gittergewebe eingebettet ist.The technological background counts through the EP 0 094 524 A2 a Korknoppenplatte, wherein between two layers of a vulcanizable mixture of an elastomer and cork powder, a mesh fabric is embedded.

Aus der EP 1 533 043 A1 geht ein Verfahren und eine Vorrichtung zum Beschichten von Holz oder Holzwerkstoffen hervor. Hierbei wird die Versiegelungsschicht erwärmt und ein Metallband auf die Versiegelungsschicht gedrückt. Die Versiegelungsschicht wird dann abgekühlt, wobei die Metallbahn die Oberfläche der Versiegelungsschicht so lange kontaktiert, bis diese erstarrt ist. Das Metallband kann eine matte, glatte, geätzte, geprägte oder strukturierte Oberfläche aufweisen.From the EP 1 533 043 A1 is a method and an apparatus for coating wood or wood-based materials out. In this case, the sealing layer is heated and a metal strip is pressed onto the sealing layer. The sealant layer is then cooled, with the metal web contacting the surface of the sealant layer until it solidifies. The metal strip may have a matte, smooth, etched, embossed or textured surface.

Gängig sind Kork-Fußbodendielen mit einem Dreischichtaufbau und profilierten Fügeflächen, dem sogenannten Klicksystem, welches eine mechanische Verriegelung entlang der Stoßkanten der Fußbodendielen ermöglicht. Die Trägerplatte oder Mittellage besteht aus einer hochverdichteten Faserplatte (HDF). In die Trägerplatte wird die Klickverbindung eingefräst. Als Deck- bzw. Nutzschicht wird auf die Trägerplatte eine Korkschicht aufkaschiert. Üblich ist weiterhin ein Gegenzug, der ebenfalls aus einer Korkschicht besteht. Dieser dient gleichzeitig als Trittschallkaschierung.Common are cork floorboards with a three-layer structure and profiled joining surfaces, the so-called click system, which enables a mechanical locking along the abutting edges of the floorboards. The carrier plate or middle layer consists of a high-density fibreboard (HDF). The click connection is milled into the carrier plate. As a cover or wear layer, a cork layer is laminated onto the carrier plate. Also usual is a return, which also consists of a cork layer. This also serves as impact sound lamination.

Die bekannten Korkpaneelen gibt es in unterschiedlichen Farben und Optiken. Dennoch besteht ein Bedarf, die Optik und Variationsmöglichkeiten dieses Naturmaterials zu erweitern.The well-known cork panels are available in different colors and looks. Nevertheless, there is a need to broaden the look and variation of this natural material.

Der Erfindung liegt daher ausgehend vom Stand der Technik die Aufgabe zu Grunde, eine Fußboden-, Wand- oder Deckenpaneele zu schaffen, die eine Nutzschicht aus Kork aufweist mit einer markanten Optik und ein Verfahren zur Herstellung einer solchen Fußboden-, Wand- oder Deckenpaneele aufzuzeigen.The invention is therefore based on the prior art based on the object to provide a floor, wall or ceiling panels, which has a wear layer of cork with a striking appearance and a method for producing such a floor, wall or ceiling panels show ,

Der gegenständliche Teil der Aufgabe wird durch eine Fußboden-, Wand- oder Deckenpaneele gemäß Anspruch 1 gelöst.The objective part of the object is achieved by a floor, wall or ceiling panels according to claim 1.

Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Paneele ist Gegenstand des abhängigen Anspruchs 2.An advantageous embodiment of the panels according to the invention is the subject of the dependent claim. 2

Nach der Erfindung weist die oberseitige Korkschicht eine geprägte Oberflächenstruktur auf. Vorzugsweise besitzt die Korkschicht eine Dicke von mindestens 2 mm. Die Korkschicht selbst kann mehrschichtig aufgebaut sein und beispielsweise aus einem Korkfurnier auf einem Granulatkork bestehen. Möglich ist selbstverständlich auch die Verwendung einer kompakten Korkschicht. Die Oberfläche der Korkschicht ist mit einem Dekor bedruckt, vorzugsweise mit einem zweischichtigen Druckbild. Zur Erhöhung der Widerstandsfähigkeit der Korkschicht ist diese mit einer Versiegelung versehen. Dies ist in Form des Auftrags einer Lack-, Öl- oder Wachsschicht möglich.According to the invention, the top-side cork layer has an embossed surface structure. Preferably, the cork layer has a thickness of at least 2 mm. The cork layer itself can have a multilayer structure and, for example, consist of a cork veneer on a granulated cork. Of course, it is also possible to use a compact cork layer. The surface of the cork layer is printed with a decor, preferably with a two-layer printed image. To increase the resistance of the cork layer this is provided with a seal. This is possible in the form of the application of a paint, oil or wax layer.

Die Lösung des verfahrensmäßigen Teils der Aufgabe zeigt Anspruch 3 auf.The solution of the procedural part of the task shows claim 3.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind Gegenstand der abhängigen Ansprüche 4 bis 10.Advantageous developments of the method according to the invention are the subject matter of the dependent claims 4 to 10.

Kernpunkt des erfindungsgemäßen Verfahrens bildet das Prägen einer Oberflächenstruktur in die Korkschicht. Hierdurch lassen sich dekorative und dauerhafte Oberflächenstrukturen in der Korkschicht erzeugen, welche die natürliche Zeichnung der Korkschicht unterstützen und oder zusätzliche Akzente setzen.The core of the process according to the invention is the embossing of a surface structure into the cork layer. As a result, decorative and permanent surface structures in the cork layer can be produced, which the support natural drawing of the cork layer and or add extra accents.

Die Korkschicht ist mit einem Dekor bedruckt. Die Korkschicht wird vor dem Prägen der Oberflächenstruktur bedruckt. Dies kann in einer oder mehreren Druckschichten erfolgen. Besonders ansprechende Dekore, z.B. mit floralen Elementen, lassen sich über Druckwalzen erzeugen. Hierdurch kann die ästhetische Wirkung der geprägten Oberflächenstruktur unterstützt werden.The cork layer is printed with a decor. The cork layer is printed before embossing the surface structure. This can be done in one or more print layers. Particularly attractive decors, e.g. with floral elements, can be generated by pressure rollers. As a result, the aesthetic effect of the embossed surface structure can be supported.

Die optischen Eigenschaften ebenso wie die Gebrauchseigenschaften und Abriebfestigkeit einer erfindungsgemäßen Fußboden-, Wand- oder Deckenpaneele lassen sich weiter steigern, wenn die Korkschicht versiegelt wird. Hierzu kann die Korkschicht lackiert, geölt und/oder gewachst werden.The optical properties as well as the performance and abrasion resistance of a floor, wall or ceiling panels according to the invention can be further increased when the cork layer is sealed. For this purpose, the cork layer can be painted, oiled and / or waxed.

Vorzugsweise wird die Korkschicht vor oder beim Prägen auf eine Temperatur zwischen 40 °C und 60 °C erwärmt.Preferably, the cork layer is heated to a temperature between 40 ° C and 60 ° C before or during embossing.

Kork ist elastisch und hat ein hohes Rückverformungsverhalten. Bei Normaltemperaturen lässt sich eine Prägestruktur daher nur bedingt in der Korkschicht erzeugen bzw. die Ergebnisse sind weniger zufriedenstellend. Wird die Korkschicht aber auf einem Temperaturbereich von 40 °C bis 60 °C erwärmt, lässt sich der Kork sehr gut verformen und die Oberflächenstruktur aufbringen. Die Oberflächenstruktur bleibt dauerhaft erhalten. Dies gilt insbesondere im Zusammenhang mit einer Trägerplatte auf Basis von HDF oder MDF. Eine druckstabile Trägerplatte gewährleistet, dass die zwischen der Korkschicht und der Trägerplatte befindliche Kleberschicht beim Präger und der dabei einwirkenden Kräfte nicht zerstört wird. Vorzugsweise kommt eine Trägerplatte aus einem Werkstoff mit einer Dichte größer 820 kg/m3 zum Einsatz.Cork is elastic and has a high rebound behavior. At normal temperatures, therefore, an embossed structure can only be produced to a limited extent in the cork layer or the results are less satisfactory. However, if the cork layer is heated to a temperature range of 40 ° C to 60 ° C, the cork can be deformed very well and the surface structure applied. The surface structure is permanently retained. This applies in particular in connection with a carrier plate based on HDF or MDF. A pressure-stable carrier plate ensures that the adhesive layer between the cork layer and the carrier plate is not destroyed by the embossing machine and the forces acting on it. Preferably, a carrier plate made of a material having a density greater than 820 kg / m 3 is used.

Die Korkschicht ist auf die Trägerplatte mittels eines Kaschiermittels aufgeklebt. Als Kaschiermittel können Dispersionskleber, Harnstoffharze, Polyurethansysteme und ähnliche Klebstoffe verwendet werden.The cork layer is glued to the carrier plate by means of a laminating agent. The laminating agents used may be dispersion adhesives, urea resins, polyurethane systems and similar adhesives.

Vorzugsweise erfolgt die Erwärmung der Korkschicht indirekt über die Prägewalze. Hierbei wird die Oberflächenstruktur in die Korkschicht mittels einer beheizten Prägewalze erzeugt. Die Prägewalze wird vorzugsweise elektrisch oder mittels Thermoöl beheizt. Die Temperatur der Prägewalze und die Kontaktzeit zwischen Prägewalze und Korkschicht werden so eingestellt, dass die gewünschte Prägetemperatur zwischen 40 °C und 60 °C der Korkschicht zuverlässig erreicht wird.The heating of the cork layer preferably takes place indirectly via the embossing roller. Here, the surface structure is produced in the cork layer by means of a heated embossing roller. The embossing roller is preferably heated electrically or by means of thermal oil. The temperature of the embossing roller and the contact time between embossing roller and cork layer are adjusted so that the desired embossing temperature between 40 ° C and 60 ° C of the cork layer is reliably achieved.

Der Auftrag des Druckdekors wird auf die geprägte Oberflächenstruktur abgestimmt, so dass die Prägung synchron zu dem aufgedruckten Deokor erscheint. Zweckmäßiger Weise wird das Dekor deckungsgleich mit der Prägung aufgebracht, wobei eine Überlappung von Dekor und Prägung von +/- 2 mm möglich ist.The print decor's job is matched to the embossed surface texture so that the embossing appears in sync with the printed deodorant. Appropriately, the decor is applied congruent with the embossing, with an overlap of decor and embossing of +/- 2 mm is possible.

Zur Erzielung einer optisch ansprechenden Oberflächenstruktur sollte die Korkschicht eine Dicke von mindestens 2 mm aufweisen. Eine solche Korkschicht lässt sich sehr gut prägetechnisch bearbeiten, so dass stabile Strukturen erzeugt werden können.To achieve a visually appealing surface structure, the cork layer should have a thickness of at least 2 mm. Such a cork layer can be very well embossed technically, so that stable structures can be produced.

Als Trägerplatte bewährt haben sich solche aus Faserwerkstoffen, wie hochverdichtete oder mittelverdichtete Faserplatten. Grundsätzlich können auch Trägerplatten aus Schichtwerkstoffen, wie Sperrholzplatten, zur Anwendung gelangen.Have proven useful as a support plate are those made of fiber materials, such as high-density or medium-density fiberboard. In principle, carrier plates made of layer materials, such as plywood boards, can also be used.

Zum Einsatz einer erfindungsgemäßen Paneele im Fußbodenbereich, also als Fußbodendiele, kann diese mit einer unterseitigen Trittschalldämmung versehen werden.To use a panel according to the invention in the floor area, ie as a floorboard, this can be provided with an underside impact sound insulation.
