Definitions

  • the invention relates to a component, in particular a panel, of wood-based material, in particular for use as a furniture component or wall, ceiling or floor panel, with a surface layer and a surface layer partially covering the material order. Furthermore, the invention relates to a method for producing such a device in which a surface layer is applied to a carrier plate of wood material or a carrier profile of wood material, and in which a paint-like material order is printed on the surface layer.
  • Wood-based panels with decorative coating are often used as floor panels and for the cladding of walls and ceilings or as furniture components. Such panels usually have a rectangular shape and are usually provided at least at their longitudinal edges with profiles that allow a coupling of adjacent panels to create a large-scale surface can. Wood fiber boards, preferably so-called dry-process MDF (Medium Density Fiberboard) or HDF (High Density Fiberboard) boards, are widely used for this purpose.
  • dry-process MDF Medium Density Fiberboard
  • HDF High Density Fiberboard
  • papers impregnated with a synthetic resin and predried can also be pressed directly onto the surfaces of the plates under high heat and pressure in order to produce the same to apply desired decor. Since these impregnates tend to shrink during compression, they create a tension, which is why these plates must always be provided on both sides with an impregnated paper in order to prevent a voltage-induced bending of the plates.
  • the laminate-coated wood fiber boards also directly coated panels are used for panels of the type mentioned recently.
  • panels are, for example, from the EP 1 645 339 A1 known.
  • the fiberboards are provided with liquid coating compositions, wherein a decor, for example a wood decor is printed on a colored base layer and finally one or more transparent sealing layers are applied.
