Description

Placa de material derivado de la madera, especialmente panel de suelo.Wood derived material plate, especially floor panel.

La invención se refiere a una placa de material derivado de la madera, especialmente un panel de suelo, con una lengüeta configurada en al menos un borde lateral, una ranura configurada en el borde lateral opuesto, una cara superior así como una cara inferior, y con una decoración impresa directamente sobre la cara superior.The invention relates to a material plate derived from wood, especially a floor panel, with a tab set in at least one side edge, one groove configured on the opposite side edge, an upper face as well as a lower face, and with a decoration printed directly on the upper face

Los paneles de suelo con una placa de soporte de material derivado de la madera se denominan habitualmente paneles laminados y desde hace muchos años se encuentran en el mercado para la sustitución del parqué. La decoración deseada (parqué, veteado de la madera, baldosas, etc.) se imprime sobre una banda de papel, que a continuación se recubre con resina y se enrolla en un rollo. El fabricante de suelos coloca la banda decorativa prefabricada de este modo sobre la placa de soporte y se comprime. Mediante la impresión de la decoración sobre la banda de papel, el sellado posterior de la banda de papel con resina sintética y la unión posterior de la capa decorativa con la placa de soporte mediante presión y temperatura se modifican las dimensiones de la banda de papel. El técnico habla de un crecimiento del papel. El papel crece tanto con respecto a su longitud (crecimiento a lo largo) como a su anchura (crecimiento a lo ancho). Cuando esta placa decorativa debe cortarse ahora para obtener paneles individuales, deben tenerse en cuenta el crecimiento a lo largo y a lo ancho, porque de lo contrario se produciría una distribución de la decoración irregular sobre los paneles individuales. Esto tendría como consecuencia, que el suelo compuesto por una capa decorativa de distribución irregular presentaría discontinuidades de la decoración en los bordes de unión de los paneles. Incluso cuando tales discontinuidades de la decoración sólo ascienden a pocos milímetros, llaman la atención al observarlas, lo que influye negativamente en la impresión estética y con ello, reduce la calidad del suelo entarimado.The floor panels with a support plate wood-derived material are usually called panels rolled and for many years are in the market for Parquet replacement. The desired decoration (parquet, veined of wood, tiles, etc.) is printed on a paper strip, which is then coated with resin and rolled into a roll. The floor manufacturer places the prefabricated decorative band of this mode on the support plate and is compressed. By means of the Decoration print on paper strip, sealing Back of the paper band with synthetic resin and the joint back of the decorative layer with the support plate by pressure and temperature the band dimensions of paper. The technician talks about a paper growth. Paper grows both with respect to its length (growth along) and its width (width growth). When this decorative plate should cut now to get individual panels, they must be kept in growth and length account, because of what on the contrary there would be an irregular decoration distribution on the individual panels. This would have as a consequence, that the floor composed of a decorative distribution layer irregular would present decoration discontinuities in the joining edges of the panels. Even when such decoration discontinuities only amount to a few millimeters, they attract attention by observing them, which negatively influences aesthetic impression and thereby reduce soil quality parquet.

Para poder producir con una buena calidad, debe registrarse el crecimiento del papel y ajustarse correspondientemente la sierra, que sierra a medida los paneles a partir de la placa de soporte. Un ajuste manual es muy complejo. El documento DE 100 19 054 describe un procedimiento para el corte a medida de paneles a partir de una placa de soporte, con el que la sierra puede adaptarse automáticamente al crecimiento del papel. Para ello se requieren cámaras, que determinan la posición real de puntos decorativos definidos. Con ello se compara la posición real con la posición nominal y se determina la desviación de la medida a lo ancho o a lo largo, de modo que la sierra puede ajustarse correspondientemente.To be able to produce with good quality, you must register paper growth and adjust correspondingly the saw, which saw the panels to measure from the support plate. A manual adjustment is very complex. He DE 100 19 054 describes a procedure for cutting a measurement of panels from a support plate, with which the saw can automatically adapt to paper growth. This requires cameras, which determine the actual position of defined decorative points. This compares the actual position with the nominal position and the deviation of the measurement is determined width or length, so that the saw can be adjusted correspondingly.

Las propiedades de aislamiento acústico de paneles laminados son peores en comparación con el parqué. Para reducir la formación de ruidos al andar por el suelo, se extienden sobre el suelo o bien esteras antiacústicas de plástico, sobre las que a continuación se colocan los paneles, o bien el fabricante aplica ya sobre la cara inferior de la placa de soporte una capa antiacústica.The sound insulation properties of Laminated panels are worse compared to parquet. For reduce the formation of noise when walking on the ground, extend on the floor or plastic anti-acoustic mats, on the that the panels are then placed, or the manufacturer apply a layer on the underside of the support plate anti-acoustic

Por un lado la estructura del suelo se hace más gruesa por la capa antiacústica necesaria. Para el entarimado posterior de espacios con paneles laminados (por ejemplo como sustitución de suelos enmoquetados) se desea sin embargo, que los paneles sean delgados. La aplicación de la capa antiacústica sobre la cara inferior de la placa de soporte requiere por otro lado una operación adicional y material adicional, lo que aumenta los costes de producción. La extensión de una película antiacústica sobre el suelo debe realizarse con mucho cuidado, para llegar a un aislamiento eficaz del ruido de pasos.On the one hand the soil structure becomes more thick due to the necessary antiaacoustic layer. For the floorboard back of spaces with laminated panels (for example as replacement of carpeted floors), however, it is desired that panels are thin. The application of the anti-acoustic layer on the underside of the support plate requires on the other hand a additional operation and additional material, which increases costs of production. The extension of an anti-acoustic film about the soil must be done very carefully, to reach a effective isolation from step noise.

Por el documento WO 01/48333 A1 se conoce un procedimiento para la producción de paneles de suelo del tipo descrito al principio, en el que sobre la cara superior de una capa de núcleo de material derivado de la madera se aplica una decoración mediante impresión. A continuación se barniza sobre la cara superior de la capa de núcleo una capa de uso al menos parcialmente transparente, o se aplica mediante la colocación de capas impregnadas de resina y que contienen \alpha-celulosa. Cuando la capa de uso está compuesta por una laca, la laca se aplica en varias capas. En las capas de laca individuales de la capa de uso se introducen partículas de corindón según la necesidad, de modo que las capas de laca externas tienen una resistencia al desgaste superior a las capas de laca internas. Es cierto que con este procedimiento se soluciona el problema del crecimiento del papel. Sin embargo no se proporciona una solución para el aislamiento del ruido de pasos.From WO 01/48333 A1 a known procedure for the production of floor panels of the type described at the beginning, in which on the top face of a layer core of wood-derived material is applied a decoration by printing. It is then varnished on the upper face of the core layer a layer of use at least partially transparent, or applied by placing layers impregnated with resin and containing α-cellulose. When the usage layer is Composed of a lacquer, the lacquer is applied in several layers. In the individual lacquer layers of the use layer are introduced corundum particles as needed, so that the layers of External lacquers have a wear resistance greater than internal lacquer layers. It is true that with this procedure you solve the problem of paper growth. However I don't know It provides a solution for step noise isolation.

El documento WO 03/16655 A1 describe un panel de suelo con una capa de cubrición dura. Debajo de la capa de cubrición dura está prevista al menos una capa antisonora, que está integrada en el panel del suelo. Esta capa antisonora está compuesta por ejemplo de corcho o un material sintético.WO 03/16655 A1 describes a panel of floor with a hard covering layer. Under the layer of hard covering is provided at least one anti-sound layer, which is integrated into the floor panel. This soundproof layer is composed for example of cork or a synthetic material.

El documento EP 1 262 607 A1 da a conocer una placa de suelo de un material derivado de la madera, especialmente MDF o HDF, sobre la que hay aplicadas una capa decorativa y una capa de desgaste. Sobre la cara posterior dirigida hacia la placa de soporte de la capa decorativa hay aplicada una capa de poliuretano.EP 1 262 607 A1 discloses a floor plate of a wood-derived material, especially MDF or HDF, on which a decorative layer and a layer are applied of wear On the back face directed towards the plate decorative layer support there is applied a layer of polyurethane.

El documento EP 0 884 172 A2 da a conocer una placa de material derivado de la madera para su uso como recubrimiento de suelos o revestimiento de pared, en la que la capa de soporte central está compuesta por madera contrachapada. Sobre una de las caras de la capa de soporte se encuentra una capa superficial y sobre la cara opuesta, una capa antiacústica de corcho.EP 0 884 172 A2 discloses a wood-derived material plate for use as floor covering or wall covering, in which the layer Central support is composed of plywood. On one of the faces of the support layer is a layer superficial and on the opposite face, an antiacustic layer of cork.

El documento DE 203 15 676 U1 describe un panel, especialmente un panel de suelo, con un núcleo de MDF o HDF y una decoración aplicada sobre la cara vista. La cara vista está dotada por al menos un borde lateral de un bisel que discurre formando un ángulo con respecto al mismo, que también presenta una decoración.Document DE 203 15 676 U1 describes a panel, especially a floor panel, with an MDF or HDF core and a decoration applied to the face. The face is endowed by at least one side edge of a bevel that runs forming a angle with respect to it, which also presents a decor.

Partiendo de este planteamiento se mejorará la placa de material derivado de la madera descrita al principio.Starting from this approach, the wood-derived material plate described at the beginning.

La solución del problema se realiza con una placa de material derivado de la madera del tipo genérico porque sobre la decoración hay aplicada una primera capa elástica de laca y sobre la primera capa de laca hay aplicada una segunda capa de laca, que en comparación con la primera capa de laca es menos elástica y más dura.The solution of the problem is done with a wood-derived material plate of the generic type because on the decoration there is applied a first elastic lacquer layer and on the first layer of lacquer there is applied a second layer of lacquer, which compared to the first layer of lacquer is less Elastic and harder.

Mediante la configuración de la placa según la invención se elimina en primer lugar la capa de papel. En consecuencia la decoración no puede modificarse ni a lo largo ni a lo ancho. La sierra, con la que posteriormente se cortan paneles a medida, puede estar ajustada previamente. Mediante la capa elástica de laca, que está aplicada directamente sobre la decoración, se atenúa el ruido de pasos, de modo que se mejoran las propiedades del ruido de pasos. La capa de laca menos elástica y más dura, preferiblemente inelástica aplicada sobre la capa elástica de laca evita el desgaste por abrasión o daños de la superficie. Mediante la segunda capa de laca inelástica puede ajustarse una dureza de la superficie, que corresponde a los panales de suelo laminados convencionales.By configuring the board according to the invention is first removed the paper layer. In consequently the decoration cannot be modified either along or wide The saw, with which panels are subsequently cut to measure, can be adjusted previously. By elastic layer of lacquer, which is applied directly to the decoration, is attenuates step noise, so that the properties of the step noise The less elastic and harder lacquer layer, preferably inelastic applied on the elastic lacquer layer Prevents abrasion or surface damage. By means of the second layer of inelastic lacquer can adjust a hardness of the surface, which corresponds to laminated floor panels conventional.

En la segunda capa de laca pueden estar diseminadas partículas de corindón, para aumentar la resistencia a la abrasión del panel de suelo.In the second layer of lacquer can be disseminated corundum particles, to increase resistance to the abrasion of the floor panel.

Las lacas de las capas de laca pueden endurecerse preferiblemente por UV, con lo que se acortan los tiempos de fabricación.Lacquers of lacquer layers can preferably harden by UV, thereby shortening the manufacturing times

Para permitir que la decoración impresa tenga un efecto brillante, las capas de laca son preferiblemente transparentes.To allow the printed decoration to have a bright effect, lacquer layers are preferably transparent.

De manera preferible en otro borde lateral también está configurada una lengüeta y en el borde lateral opuesto a éste, una ranura.Preferably on another side edge a tongue is also configured and on the opposite side edge to this one, a slot.

Cuando la lengüeta y la ranura están dotadas de medios de bloqueo, que en el caso de dos paneles unidos entre sí evitan un deslizamiento transversal a la dirección de unión, puede colocarse el suelo sin cola de manera flotante.When the tongue and groove are equipped with locking means, which in the case of two panels joined together prevent a transverse sliding to the direction of union, can place the floor without a tail in a floating way.

Con la ayuda de un dibujo se describirá a continuación un ejemplo de realización de la invención con más detalle. Muestra:With the help of a drawing, we will describe below an example of embodiment of the invention with more detail. Sample:

Sobre la cara 10 superior está impresa directamente una decoración, por ejemplo un veteado de madera. Sobre la decoración hay aplicada una capa 3 elástica de laca, que a su vez se recubre por una capa 4 inelástica de laca, en la que pueden estar diseminadas partículas de corindón. Las lacas de las capas 3, 4 de laca pueden endurecerse por UV. En la cara 9 inferior está prevista dado el caso una estabilización (no mostrada) que evita una deformación del panel 7 a consecuencia de las fuerzas de tracción que aparecen a través de las capas 3, 4 de laca. Las lengüetas 1, 11 están dotadas de medios 5 de bloqueo, que corresponden con medios 6 de bloqueo previstos en la ranura 2 y que bloquean los paneles contra un deslizamiento en la dirección transversal.The floor panel 7 has a core of one wood-derived material, preferably HDF or MDF. For longitudinal edge I and a transverse edge III panel 7 is equipped with a tongue 1, 11 and opposite edge II, IV It is provided with a slot 2, 12 corresponding thereto. On Top face 10 is directly printed a decoration, by example a wood grain. On the decoration there is a elastic lacquer layer 3, which in turn is coated by a layer 4 inelastic lacquer, in which particles may be disseminated Corundum Lacquers of lacquer layers 3, 4 can harden by UV. In the lower face 9, if necessary, a stabilization (not shown) that prevents deformation of panel 7 as a result of the tensile forces that appear through 3, 4 layers of lacquer. The tabs 1, 11 are provided with means 5 blocking, corresponding to blocking means 6 provided in slot 2 and that lock the panels against a slip in the cross direction.
