Definitions

  • the present invention relates to a method of making a panel having a decorative surface, the panel being made of a lignocellulosic material-based support material, such as a sheet metal. Chipboard, OSB board or fiber board is made. Likewise, the invention relates to a plate having a decor having a surface and a use of the plate as a floor panel or as a furniture board.
  • decorative surfaces are achieved on said substrates by coating with printed papers.
  • These processes typically use a plurality of papers impregnated with synthetic resin, preferably melamine, melamine / urea or phenolic resins. At elevated pressure and temperature, these are then pressed either directly (Direct Pressure Laminate (DPL)) or only after their processing into a laminate with the substrate (High Pressure Laminate (HPL) or Continuous Pressure Laminate (CPL)).
  • DPL Direct Pressure Laminate
  • HPL High Pressure Laminate
  • CPL Continuous Pressure Laminate
  • the papers containing the décor can be freely designed in their color, printed with any desired decors such as wood decors, tile or stone decors, fantasy decors and all other conceivable motifs and patterns.

  • particles of quartz, nitrides and carbides SiO 2 and corundum (OC-Al 2 O 3 ) are known. Recently, however, the use of very small particles of glass or diamond has become known here.
  • the following layers are applied to achieve a decorative surface on a lignocellulose-based carrier material depending on the intended use of the workpieces and the demands placed on their resistance, wherein a pre-treatment may precede by grinding:
  • Primer As a first treatment step, the surface to be treated is usually prepared with a primer (adhesion promoter) for a subsequent coating.
  • the primer preferably consists of the same basic components as the subsequently applied layer.
  • Filler These have the task on the one hand to reduce the absorption of the substrate and also to provide adhesion to the subsequent layers. Depending on the requirements arising from the later field of use of the workpieces and thus from the subsequently applied layers, it may be useful to apply the filler in two or more operations which may be an intermediate or at least partially hardened. In addition, the filler also serves to fill in irregularities in the surface in order to compensate for them.
  • Primer This is applied after at least partial hardening of the filler.
  • the purpose of the primer which can also be built up again from different individual layers with intermediate or subsequent, at least partial curing, is to achieve the prevailing in the decor basic shade. For most wood finishes, coatings with beige to brown shades or even red shades are predominantly applied in this work step.
  • Printing ink Depending on the color variety of the decoration to be applied and the desired lot sizes, the printing process known from the prior art, such as, for example, the stencil printing process or the offset printing process, is used in this step desired printed image applied. The use of digital printing methods is also already known for this field of application.
  • Sealing Just as with the sealing of solid wood surfaces, with comparable methods a protection of the surface and also an improved visual appearance is achieved. The only difference is that it is a previously applied decor is coated and not a predetermined from the use of solid wood image. In addition to the upgrading of the decoration applied by the preceding step, protection against external influences should thus also be achieved in order to obtain the desired optical quality over the intended period of application. For example, by selecting the appropriate seal, the desired degree of gloss of the surface, a given scratch resistance or a specific abrasion resistance can be achieved. Depending on the various optical properties and the loads to be expected, the number of layers applied here is selected, which are optionally hardened in order to bring about a partial crosslinking coordinated with the subsequent steps.
  • the predominantly used radiation-curable systems here can also contain hard particles to achieve high abrasion resistance. It is also possible to scatter the particles on a not yet or already partially cured layer in order to achieve the desired abrasionsresistenten properties.
  • By selecting different particle sizes in or on the different layers their use can be optimized, for example, the choice of small particle sizes in or on one of the upper layers has as proved to be favorable for achieving high abrasion resistance.
  • Other additives such as so-called UV absorbers, which form an increased protection against UV radiation and so prevent unwanted premature yellowing, may be included in the seal to achieve desired optical properties or to obtain these over the intended period of application.
  • An opening provided for a subsequent grinding layer may be applied to the desired smoothness of the end product to achieve 'between the sealing layers.
  • the systems used can be based on organic solvents or else be water-based. To harden the various layers, it is possible to adjust the temperature, UV radiation, ionizing radiation such as electron beams, or other methods and devices known for said purposes, may be used alone or in combination.
  • An advantage of printing on the panels, rather than laminating the panels with a laminate, is that a backing layer on the back of the panel can be avoided. As a result, the production costs can be further reduced.
  • the image in particular is also impaired by the fact that the roughness of the surface leads to a running of the individual pixels with each other. Even if, for example, it has been printed with a resolution of 54 dots per cm or 2,916 dots per cm 2 , the picture shows a lower resolution, since the pixels are no longer clearly separated from each other.

Likewise, the roller can be moved so that no relative movement between the roller surface and the surface of the plate is formed.

Abstract

L'invention concerne un procédé pour fabriquer un panneau doté d'une surface présentant un décor, lequel panneau est constitué d'un matériau support à base de matière lignocellulosique. La couche de fond appliquée est polie au moyen d'un dispositif de polissage, ce qui permet d'obtenir une image imprimée de meilleure qualité. Cette invention concerne également un procédé selon lequel un système de résine synthétique est appliqué comme couche de fond et/ou couche de scellement sur la surface du panneau. Ladite invention concerne en outre des panneaux ainsi fabriqués et leur utilisation comme panneaux de plancher ou de meuble.
