Definitions

  • the invention relates to a method for producing a matt embossing surface of an embossing tool used for the surface shaping of press laminates or the like by matt chromium plating or by sandblasting and subsequent matt chromium plating.
  • Coated wood-based panels or laminate panels are required on the market in many surface designs. This includes - patterned or smooth surfaces with different degrees of gloss from matt to high-gloss, for which appropriate embossing tools or press plates have to be provided for their production.
  • the invention is based on the fact that it is used for the production of structures on press plates.
  • B. from DE-AS 27 06 947 or DE-PS 31 20 351 is known to use embossing rollers and the etching process.
  • the etching process can be used to form single-stage or multi-stage structures, etching reserves being applied to the press plate in specific patterns by means of cliché rollers and being etched after each coating. As a rule, the surface is then polished and matted by sandblasting.
  • the structure pattern can be arbitrary, e.g. B. fine structures, corrugations, knobs, wood grain.
  • the invention has for its object to develop a method for producing a substantially improved matte embossing surface of such an embossing tool, so that the matte finished plates made with it aesthetically and haptically satisfy, do not appear artificial and cold and are insensitive to fingerprints.
  • the embossing surface is provided with a fine, directionless, 10 ⁇ m to 25 ⁇ m deep substructure before matting and is then matted so that the degree of gloss 6 to 16 measured with the Lange Re lectometer 60 ° Points. It has surprisingly been found that with such an embossed surface it is possible to create furniture surfaces which, although they give the impression of smooth surfaces optically and haptically, have the desired favorable properties, that is to say they no longer act as artificially a warmer impression, indeed feel warmer due to the air in the recesses of the structure, which has an insulating effect on the surface of the skin, and are relatively insensitive to fingerprints.
  • the depth of the substructure and the matting are selected and matched to one another such that the substructure can no longer be recognized as such after the matting.
  • a smaller depth of the substructure is unsuitable because it would lead to a practically completely smooth surface, and at a depth of more than 25 ⁇ m the structure would remain undesirably recognizable after matting. Matting with gloss levels above 16 points is also unsuitable because it makes the substructure visible.
  • the depth of the substructure can be varied within the boundary areas and a matting adapted to it can be made, the choice depending on how strongly the haptic property of the surface should be pronounced and what aesthetic effect the surface should have.
  • the substructure can be produced using one of the known structuring methods. Particularly suitable is the etching process, which was previously used to represent structures that are supposed to give the surface of the finished plate the aesthetic effect.
  • the representation of the ultra-fine substructure according to the invention forms only an intermediate stage, which is followed by further surface treatments.
  • the etching process can be carried out either once or in several stages with different structures, e.g. B. coarse and fine structured cliché rollers can be used.
  • the press plate is polished electrolytically or mechanically and then matted.
  • the matting can be carried out in one stage by matt chrome plating or in two stages by sandblasting and then matt chrome plating. Then hard chrome plating is carried out to protect the surface.
  • the haptic effect and the appearance can be adapted to the wishes and requirements by using the etching process once or several times and the one- or two-stage matting.

Abstract

Pour améliorer la qualité et les propriétés d'utilisation de la surface d'estampage d'un outil d'estampage servant au formage des surfaces de stratifiés emboutis ou autres, la surface d'estampage est revêtue, avant le matage, d'une structure de fond fine et non orientée, de préférence si fine qu'elle n'est plus reconnaissable comme telle après le matage. Le matage sera obtenu soit par chromage mat soit par sablage et suivi d'un chromage mat. La structure de fond est réalisée par un procédé d'attaque chimique pouvant être réalisé en une seule ou en plusieurs étapes.
