Definitions

  • the invention relates to wood-based materials with coating and method for their preparation.
  • Wood-based materials with coating representing a base layer or primer layer for subsequent printing by means of digital printing, are known in principle.
  • Such base layers or primer layers are often present as monochrome or light layers.
  • An embodiment is preferably in white.
  • transparent primer layers are also known.
  • wood materials with a rolled base layer of the prior art are known.
  • this priming process is always a process step which is completely independent of a subsequent digital printing process and entails renewed set-up times for a subsequent or subsequent process step. Due to the process, it is also to be regarded as disadvantageous that when applying a base layer by means of applicator rollers, the materials are usually only coated over the entire surface. On the other hand, subregions of the materials can not be designed to be precisely limited. Free, not linear limited areas are difficult to represent by rolling.
  • the base layer produced by means of roller application has a cloudy, non-homogeneous appearance in the case of a subsequent compression of a so-called overlay by the action of force.
  • Printing process is completely independent process step.
  • Base layers can be generated only very slowly. The problem here is also to consider the generation of constant layer thickness of a so-called base layer.
  • base coats were produced by means of piezoprinting, wherein it has proven to be disadvantageous that only small layer thicknesses can be produced. Repeated overprinting as a remedy for this is too costly. It is also considered problematic when primers with large and / or coarse pigments are to be printed. By way of example, mention may be made of primers / inks containing titanium dioxide as the colorant. Clogged or even defective printheads are often the consequences.
  • the object of the invention is therefore to provide a wood material with a coating in the form of a primer layer which does not have the disadvantages mentioned.
  • the wood-based material should have a primer layer, which in particular has a constant layer thickness, in which the edges of the coating regions are defined and can be freely selected in terms of design.

  • wood materials are understood to mean wood and / or wood substitute materials.
  • wood substitute materials are "Wood Plastic Compounds" (WPC).
  • Wood material with a base coating is achieved by a coating is formed in the pressure-valve method.
  • the wood material according to the invention with at least one coating is formed as a base or primer coating, wherein the wood material is formed as wood and / or WPC, is the at least one base or primer coating applied in a digital printing process, wherein the digital printing method is a pressure-valve method.

Abstract

L'invention concerne principalement un matériau dérivé du bois comportant au moins un revêtement, ce ou ces revêtement(s) se présentant sous la forme d'un revêtement de type couche de base ou d'apprêt et le matériau dérivé du bois se présentant sous la forme de bois et/ou de composite bois-plastique (WPC). Cette invention est caractérisée en ce que le revêtement de type couche de base ou d'apprêt est appliqué au cours d'un procédé d'impression numérique, et en ce que ce procédé d'impression numérique est un procédé faisant intervenir des soupapes de compression.
