Definitions

  • the invention relates to a method for producing a matt embossing surface of an embossing tool which serves to form the surface of press laminates or the like by matting, which is carried out in one stage by matt chrome plating or in two stages by sandblasting and subsequent matt chromium plating.
  • Furniture surfaces are now largely produced in a melamine-coated version.
  • Such surfaces whether as coated wood-based panels or as high-pressure laminate panels, are produced in hydraulic presses under heat and pressure, special embossing tools, so-called press plates, which are pressed together with the material to be pressed, being used to form the surfaces.
  • press plates which are pressed together with the material to be pressed, being used to form the surfaces.
  • the surface is produced on the material to be pressed, the surface of the finished product being a true reflection of the surface of the press plate.
  • 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 pressing plates must be made available for their manufacture.
  • the matted press plates of this type also have the disadvantage that the embossed surface is very sensitive to scratches and fingerprints are clearly visible on the finished plates that can be produced with them, and are difficult to remove.
  • 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 certain patterns by means of cliché rollers and being etched after each coating. As a rule, the surface is then polished and matted by sandblasting or by an etching process.
  • the structure pattern can be arbitrary, e.g. B. fine structures, corrugations, knobs, wood grain. Also known from EP 25 68 803 A3, a with an embossing, for. B.
  • embossing tool in the form of a wood grain, formed embossing tool by thermal spraying with a matt metal coating, u. a. made of chrome, but the embossing is retained; this matting method is also unsuitable for matting a smooth embossing surface with aesthetically and haptically satisfactory properties.
  • the invention has for its object a method for producing a significantly improved to develop matte embossing surface of such an embossing tool, so that the matte finished plates made with it satisfy aesthetically and haptically, do not appear artificial and cold and are insensitive to fingerprints.
  • embossing surface before matting is provided with a fine, directionless, 10 »m to 25» m deep substructure and then matted so that the degree of gloss measured with the Lange reflectometer 60 ° is 6 to 16 points is.
  • the depth of the substructure and the matting are selected and coordinated so that the substructure is no longer recognizable as such after matting.
  • a lower 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 an appropriate matting can be carried out, the choice depending on how strong the haptic property of the surface should be 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 has been 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 either one-time or multi-stage 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 done in one step by matt chrome plating or in two stages by sandblasting and subsequent 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.
