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 und einer an der gegenüberliegenden Seitenkante ausgebildeten Nut und einer Oberseite, einer Unterseite und einem auf die Oberseite aufgedruckten Dekor.The invention relates to a wood-based panel, in particular a floor panel, with a spring formed on at least one side edge and a groove formed on the opposite side edge and an upper side, a lower side and a decor printed on the upper 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). If this decorative panel is now to be tailored to individual panels, the length and width growth must be taken into account, 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.

Stand der TechnikState of the art

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.

Die DE 195 32 819 A1 offenbart ein Verfahren zur Herstellung einer Holzwerkstoffplatte, deren Kern mit einem Schichtaufbau verschiedener Lackschichten beschichtet wird.The DE 195 32 819 A1 discloses a method for producing a wood-based panel, the core of which is coated with a layer structure of different lacquer layers.

DE 296 02 329 U1 offenbart eine als Bodenbelag verwendbare Trägerplatte mit einer Zwischenschicht aus Holzfurnier und einer die Zwischenschicht schützenden Oberflächenschicht, die aus einer Lackierung besteht, welche hochfeste, abriebhemmende Partikel, z. B. Korund- oder Diamantpartikel, enthält. DE 296 02 329 U1 discloses a base plate usable as a floor covering with an intermediate layer of wood veneer and an intermediate layer protective surface layer consisting of a lacquer coating which high-strength, abrasion-resistant particles, for. As corundum or diamond particles containing.

Aus der EP 1 262 607 A1 ist eine Fußbodenplatte und ein Verfahren zu deren Herstellung bekannt, bei der auf einer Trägerplatte aus Holz oder einem Holzwerkstoff ein Sandwich aus einer Dekorschicht und einer der Rückseite der Dekorschicht zugewandten Polyurethanschicht, aufgebracht ist, die als Trittschalldämmschicht wirkt.From the EP 1 262 607 A1 is a floor plate and a method for their preparation is known in which on a support plate made of wood or a wood material, a sandwich of a decorative layer and the back of the decorative layer facing polyurethane layer is applied, which acts as a footfall sound insulation layer.

In der EP 1 308 577 A2 wird ein Fußbodensystem mit einer Mehrzahl von Paneelen beschrieben, bei dem jeweils an zwei gegenüberliegenden Seitenkanten zueinander korrespondierende Verbindungsmittel angeordnet sind, die eine mechanische Verriegelung der Fußbodenpaneele erlauben.In the EP 1 308 577 A2 a floor system is described with a plurality of panels, in each of which at two opposite side edges mutually corresponding connecting means are arranged, which allow a mechanical locking of the floor panels.

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 film on the subfloor must be done very carefully in order to lead to an effective insulation of the impact sound.

Aufgabenstellungtask

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 das Dekor unmittelbar auf die Oberseite aufgedruckt ist, und dass eine erste elastische Lackschicht auf das Dekor und auf die erste Lackschicht eine zweite Lackschicht aufgebracht ist, die gegenüber der ersten Lackschicht unelastisch und härter ist.The problem is solved in a generic wood-based panel characterized in that the decor is printed directly on top, and that a first elastic lacquer layer on the decor and on the first lacquer layer, a second lacquer layer is applied, which is inelastic and harder compared to the first lacquer layer.

Durch diese Ausgestaltung 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 härtere Lackschicht verhindert Verschleiß durch Abrieb oder Beschädigungen der Oberfläche.By this configuration, 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 harder lacquer layer prevents wear due to abrasion or damage to the surface.

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.

Wenn die zweite Lackschicht unelastisch ist, kann eine Oberflächenhärte eingestellt werden, die der herkömmlicher Laminat-Bodenpaneele entspricht.If the second lacquer layer is inelastic, a surface hardness corresponding to the conventional laminate floor panel can be set.

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.
