Abstract

A tongue (1) and a groove (2) are individually formed on opposite side edges (I,II). An elastic varnish layer (3) is applied to a pattern e.g. wood grain printed onto a top side. An inelastic varnish layer (4), which is harder than the elastic varnish layer, is applied to the elastic varnish layer.

Description

Die Erfindung betrifft eine Holzwerkstoffplatte, insbesondere ein Fußbodenpaneel, mit einer an mindestens einer Seitenkante ausgebildeten Feder, einer an der gegenüberliegenden Seitenkante ausgebildeten Nut, einer Oberseite sowie einer Unterseite, und mit einem direkt auf die Oberseite aufgedruckten Dekor.The invention relates to a wood-based panel, in particular a floor panel, with a tongue formed on at least one side edge, a groove formed on the opposite side edge, a top side and a bottom side, and with a decor printed directly on the top side.

Fußbodenpaneele mit einer Holzwerkstoff-Trägerplatte werden üblicherweise als Laminatpaneele bezeichnet und sind seit vielen Jahren zur Substitution von Parkett im Handel. Das gewünschte Dekor (Parkett, Holzmaserung, Fliesen usw.) wird auf eine Papierbahn aufgedruckt, die anschließend mit Harz beschichtet und auf eine Rolle aufgerollt wird. Die so vorgefertigte Dekorbahn wird bei dem Fußbodenhersteller auf die Trägerplatte aufgelegt und verpresst. Durch das Aufdrucken des Dekors auf die Papierbahn, das spätere Versiegeln der Papierbahn mit Kunstharz und das anschließende Verbinden der Dekorschicht mit der Trägerplatte durch Druck und Temperatur verändert sich die Papierbahn in ihren Abmessungen. Der Fachmann spricht davon, dass das Papier wächst. Das Papier wächst sowohl in der Länge (Längenwachstum) als auch in der Breite (Breitenwachstum). Wenn diese Dekorplatte nun zu einzelnen Paneelen zugeschnitten werden soll, müssen das Längen- und Breitenwachstum berücksichtigt werden, weil anderenfalls eine ungleiche Dekorverteilung auf den einzelnen Paneelen vorhanden wäre. Dies hätte zur Folge, dass der aus einer ungleich verteilten Dekorschicht zusammengesetzte Fußboden an den Verbindungskanten der Paneele Dekorsprünge aufweist. Selbst wenn solche Dekorsprünge nur wenige Millimeter betragen, fallen sie bei der Betrachtung auf, was den ästhetischen Eindruck negativ beeinflusst und damit die Qualität des ausgelegten Fußbodens mindert.Floor panels with a wooden base plate are commonly referred to as laminate panels and have been for many years for the substitution of parquet in the trade. The desired decor (parquet, wood grain, tiles, etc.) is printed on a paper web, which is then coated with resin and rolled up on a roll. The thus prepared decorative sheet is placed on the carrier plate and pressed at the floor manufacturer. By printing the decoration on the paper web, the subsequent sealing of the paper web with synthetic resin and the subsequent bonding of the decorative layer to the carrier plate by pressure and temperature, the paper web changes in dimensions. The expert speaks of the paper growing. The paper grows both in length (length growth) and in width (width growth). When this decorative panel is now cut to individual panels should be considered, the length and width growth, because otherwise an uneven decor distribution on the individual panels would be present. This would mean that the floor composed of an unequally distributed decorative layer has decorative jumps on the connecting edges of the panels. Even if such decorative jumps are only a few millimeters, they are noticeable when viewed, which adversely affects the aesthetic impression and thus reduces the quality of the floor designed.

Um qualitätsgerecht produzieren zu können, muss das Papierwachstum erfasst und die Säge, die die Paneele aus der Trägerplatte zurechtsägt, entsprechend eingestellt werden. Eine manuelle Einstellung ist sehr aufwendig. Die DE 100 19 054 beschreibt ein Verfahren zum Zuschneiden von Paneelen aus einer Trägerplatte, mit dem die Säge automatisch an das Papierwachstum angepasst werden kann. Hierzu sind Kameras notwendig, die die Ist-Lage definierter Dekorpunkte ermitteln. Die Ist-Lage wird damit der Soll-Lage verglichen und die Abweichung des Breiten- oder Längenmaßes ermittelt, so dass die Säge entsprechend eingestellt werden kann.In order to be able to produce in a quality-appropriate manner, the paper growth must be recorded and the saw, which saws the panels from the carrier plate, adjusted accordingly. A manual adjustment is very expensive. The DE 100 19 054 describes a method for cutting panels from a carrier plate, with which the saw can be automatically adapted to the paper growth. This requires cameras that determine the actual position of defined decorative points. The actual position is thus compared to the desired position and the deviation of the latitude or longitude is determined, so that the saw can be adjusted accordingly.

Die Schalldämmeigenschaften von Laminatpaneelen sind im Vergleich zu Parkett schlechter. Um die Geräuschentwicklung beim Begehen des Fußbodens zu reduzieren, werden auf dem Unterboden entweder Dämmmatten aus Kunststoff ausgelegt, auf die dann die Paneele aufgelegt werden, oder es wird werksseitig bereits auf die Unterseite der Trägerplatte eine Dämmschicht aufgebracht.The sound insulation properties of laminate panels are inferior compared to parquet. In order to reduce the noise when walking on the floor, either insulating mats are made of plastic on the subfloor on which then the panels are placed, or it is factory already applied to the underside of the support plate an insulating layer.

Durch die notwendige Dämmschicht wird einerseits der Fußbodenaufbau dicker. Zum nachträglichen Auslegen von Räumen mit Laminatpaneelen (beispielsweise als Ersatz von Teppichboden) ist es jedoch wünschenswert, wenn die Paneele dünn sind. Andererseits erfordert das Aufbringen der Dämmschicht auf die Unterseite der Trägerplatte einen weiteren Arbeitsgang und zusätzliches Material, was die Herstellkosten erhöht. Das Auslegen einer Dämmfolie auf dem Unterboden muss sehr sorgfältig erfolgen, um zu einer wirkungsvollen Dämmung des Trittschalls zu führen.Due to the necessary insulating layer on the one hand, the floor construction thicker. For retrofitting rooms with laminate panels (for example, as a replacement for carpeting), it is desirable if the panels are thin. On the other hand, the application of the insulating layer on the underside of the carrier plate requires a further operation and additional material, which increases the production costs. The laying out of an insulating foil on the subfloor must be done very carefully in order to lead to an effective insulation of the impact sound.

Aus der WO 01/48333 A1 ist ein Verfahren zur Herstellung von Bodenpaneelen der eingangs beschriebenen Art bekannt, bei dem auf die Oberseite einer Kernlage aus Holzwerkstoff ein Dekor durch Drucken aufgebracht wird. Anschließend wird auf die Oberseite der Kernlage eine mindestens teilweise durchsichtige Nutzschicht auflackiert, oder durch Auflegen von harzimprägnierten und α-zellulosehaltigen Lagen aufgetragen. Wenn die Nutzschicht aus einem Lack besteht, wird der Lack in mehreren Schichten aufgetragen. In die einzelnen Lackschichten der Nutzschicht werden je nach Bedarf Korundpartikel eingebracht, so dass die äußeren Lackschichten eine höhere Verschleißfestigkeit haben als die inneren Lackschichten. Mit diesem Verfahren wird zwar das Problem des Papierwachstums gelöst. Eine lösung für die Trittschalldämmung wird aber nicht gegeben.From the WO 01/48333 A1 a method for the production of floor panels of the type described above is known in which a decor is applied by printing on the top of a core layer of wood material. Subsequently, an at least partially transparent wear layer is applied to the upper side of the core layer, or applied by applying resin-impregnated and α-cellulose-containing layers. If the wear layer consists of a paint, the paint is applied in several layers. Depending on requirements, corundum particles are introduced into the individual paint layers of the wear layer so that the outer paint layers have a higher wear resistance than the inner paint layers. Although this method solves the problem of paper growth. A solution for the impact sound insulation is not given.

Die WO 03/16655 A1 beschreibt ein Fußbodenpaneel mit einer harten Deckschicht. Unterhalb der harten Deckschicht ist mindestens eine schallabsorbierende Lage vorgesehen, die in das Bodenpaneel integriert ist. Diese schallabsorbierende Lage besteht beispielsweise auf Kork oder einem synthetischen Material.The WO 03/16655 A1 describes a floor panel with a hard topcoat. Below the hard cover layer at least one sound-absorbing layer is provided, which is integrated in the floor panel. This sound-absorbing layer consists for example of cork or a synthetic material.

Die EP 1 262 607 A1 offenbart eine Fußbodenplatte aus einem Holzwerkstoff, insbesondere MDF oder HDF, auf die eine Dekorschicht und eine Verschleißschicht aufgebracht sind. Auf der der Trägerplatte zugewandten Rückseite der Dekorschicht ist eine Polyurethan-Schicht aufgebracht.The EP 1 262 607 A1 discloses a floorboard of a wood material, in particular MDF or HDF, to which a decorative layer and a wear layer are applied. On the back of the decorative layer facing the carrier plate, a polyurethane layer is applied.

Die EP 0 884 172 A2 offenbart eine Holzwerkstoffplatte zur Verwendung als Bodenbelag oder Wandverkleidung, bei der die zentrale Trägerschicht aus Sperrholz besteht. Auf der einen Seite der Trägerschicht ist eine Oberflächenschicht angebracht und auf der gegenüberliegenden Seite eine Dämmschicht aus Kork.The EP 0 884 172 A2 discloses a wood-based panel for use as a floor covering or wall covering in which the central backing layer is made of plywood. On one side of the carrier layer, a surface layer is attached and on the opposite side of an insulating layer of cork.

Die DE 203 15 676 U1 beschreibt ein Paneel, insbesondere Bodenpaneel, mit einem Kern aus MDF oder HDF und einem auf die Sichtseite aufgebrachten Dekor. Die Sichtseite ist an mindestens einer Seitenkante mit einer im Winkel hierzu verlaufenden Fase versehen, die ebenfalls ein Dekor aufweist.The DE 203 15 676 U1 describes a panel, in particular floor panel, with a core of MDF or HDF and a decor applied to the visible side. The visible side is provided on at least one side edge with a bevel running at an angle thereto, which also has a decor.

Von dieser Problemstellung ausgehend, soll die eingangs beschriebene Holzwerkstoffplatte verbessert werden.Starting from this problem, the wood-based panel initially described is to be improved.

Die Problemlösung erfolgt bei einer gattungsgemäßen Holzwerkstoffplatte dadurch, dass auf das Dekor eine erste elastische Lackschicht aufgebracht und auf die erste Lackschicht eine zweite Lackschicht aufgebracht ist, die gegenüber der ersten Lackschicht weniger elastisch und härter ist.The problem is solved in a generic wood-based panel characterized in that applied to the decor a first elastic lacquer layer and on the first lacquer layer, a second lacquer layer is applied, which is less elastic and harder compared to the first lacquer layer.

Durch die Ausgestaltung der erfindungsgemäßen Platte wird zunächst die Papierschicht eliminiert. Das Dekor kann sich folglich weder in der Länge noch in der Breite verändern. Die Säge, mit der später Paneele zugeschnitten werden, kann voreingestellt sein. Durch die elastische Lackschicht, die direkt auf das Dekor aufgebracht ist, wird der Trittschall gedämpft, so dass die Trittschalleigenschaften verbessert werden. Die auf die elastische Lackschicht aufgebrachte, weniger elastische und härtere, vorzugsweise unelastische Lackschicht verhindert Verschleiß durch Abrieb oder Beschädigungen der Oberfläche. Durch die unelastische zweite Lackschicht kann eine Oberflächenhärte eingestellt werden, die der herkömmlicher Laminat-Bodenpaneele entspricht.Due to the design of the plate according to the invention, the paper layer is first eliminated. The decor can therefore change neither in length nor in width. The saw, with which later panels are cut, can be pre-set. The elastic paint layer, which is applied directly to the decor, dampens the impact sound, so that the impact sound properties are improved. The applied to the elastic lacquer layer, less elastic and harder, preferably inelastic lacquer layer prevents wear due to abrasion or damage to the surface. The inelastic second lacquer layer can be used to set a surface hardness that corresponds to that of conventional laminate floor panels.

In die zweite Lackschicht können Korundpartikel eingestreut sein, um die Abriebfestigkeit des Fußbodenpaneels zu erhöhen.In the second coat layer corundum particles may be interspersed to increase the abrasion resistance of the floor panel.

Die Lacke der Lackschichten sind vorzugsweise UV-aushärtbar, wodurch die Fertigungszeiten verkürzt sind.The lacquers of the lacquer layers are preferably UV-curable, whereby the production times are shortened.

Um das aufgedruckte Dekor brillant wirken zu lassen, sind die Lackschichten vorzugsweise transparent.In order to make the printed decor look brilliant, the paint layers are preferably transparent.

Vorzugsweise ist auch an einer weiteren Seitenkante eine Feder und an der dieser gegenüberliegenden Seitenkante eine Nut ausgebildet.Preferably, a tongue is also formed on a further side edge and a groove is formed on the side edge opposite thereto.

Wenn die Feder und die Nut mit Verriegelungsmitteln versehen sind, die bei zwei miteinander verbundenen Paneelen ein Verschieben quer zur Verbindungsrichtung verhindern, kann der Fußboden leimlos schwimmend verlegt werden.If the spring and the groove are provided with locking means which prevent displacement of two interconnected panels transversely to the direction of connection, the floor can be installed floating glueless.

Mit Hilfe einer Zeichnung soll ein Ausführungsbeispiel der Erfindung nachfolgend näher beschrieben werden. Es zeigt:
