Definitions

  • the present invention relates to methods for improving the metallic effects and further processing criteria as well as the flexibility of resin-coated Decorative papers.
  • Printed decorative papers are used in the coating industry Coating of laminates, or they are directly on wood substitute panels applied for surface improvement and -beautification.
  • the further processing is done by impregnation with melamine resins, phenolic resins, urea resins as well as other mixed resin systems and other resin solutions as well by painting with chemically or physically curing paint systems.
  • Highly absorbent resin-impregnable decorative papers having a weight per unit area of 45 g / m 2 to 200 g / m 2 , preferably 70 g / m 2 to 90 g / m 2 , are used as materials for the substrates for the printed image and for the resin.
  • Water-dispersible decorative printing inks used are paints without organic solvents or with limited solvent content with exclusively organic color pigments and casein-based binder systems, as well as overpressure blends for mother-of-pearl based on polyurethanes.
  • RWO decorative printing inks are known, for example, under the trade names Hartmann / 761 series or Arcolor 1010/1012/3008/3017/5000/7000 and others, metallic effect colors T1332 / 761, T2630 / 761, Arcolor Ardeco brilliant silver, Ardeco brilliant mother among others, iridescent or iriondin ink.
  • Coated wood materials are made by pulling the high-pressure laminate panels (HPL) by mechanically / thermally imageable edges, in pre-milled Wood material, achieved during the bending process. This procedure is called Postforming called.
  • Conventionally produced standard base papers can be in the high pressure laminate area (HPL) not or only insufficiently around these tight Deforming radii, for example in the manufacture of countertops or Furniture fronts with rounded edges.
  • Base papers so-called postforming papers used, this after the State of the art.
  • the sandwich panels themselves receive at the critical narrow radii on the opposite side of the coating differently shaped notches or milling, as described for example in DE19830778C1. The At the outer edge of the sheet applied paper layer is here, however, considerably stretched.
  • optical and physical properties as well as the achieved metallic effect of the Finished wood-based materials are further decisive quality criteria.
  • the maximum optical effects are achieved by applying the highest possible quantities of paint scored in decor printing. These are rear cylinder with the largest possible used theoretical ink transfer volume. The maximum possible Ink transfer is limited by the drying capacity of the printing presses.
  • Binder household reduces the fixation of the pigments on the decor paper and causes during the impregnation a bleeding of the decor pressure, which in Flooding of larger amounts of metallic effect pigments in the resin liquor shows.
  • the binder content is too low, the abrasion resistance of the non-resinated material is negligible printed decorative paper so down that a run of the printed paper web as Web through the steering rollers in the impregnating without damaging the Print image is hardly possible.
  • the possibilities, higher metal effects by increasing to achieve the color order are thus limited.
  • the problems are as follows: Unhomogeneous dark and blotchy surfaces, possibly "pearlescent". Through a Increased metallic paint application are not improved mother of pearl or Metallic effects achieved more.
  • the general solution according to the invention is to delay the curing Solutions of basic metal salts during gravure printing applied. This can improve the postforming properties of the inexpensive plain papers are used, and a costly chemical Pre-treatment of special papers is eliminated. Metallic salts in the basic range are used to improve postforming properties. Continue this method improves the gloss and the metallic effects as well the reduction of pressing errors, as described above achieved. Other features, Details and embodiments will become apparent from the dependent claims.
  • HPL high-pressure laminate sector
  • the fund of homogeneous color funds on decorative papers with basis weights of 70 g / m 2 to 90 g / m 2
  • planar coating methods such as flexographic printing, Haschurwalzen Lucas or similar methods should be possible.
  • the transfer of surface ink quantities should take place wet with high ink coverage on printed or unprinted decorative papers.
  • the ink transfer in rotogravure should be done with a rear cylinder.
  • a gravure printing unit of a Dekor briefly horrinskymaschine is with a pressure cylinder printed with a homogeneously engraved grid, which is always used here as a "rear cylinder” referred to as.
  • the color transfer to the rear cylinder takes place from storage containers by means of electric pumps or pneumatic diaphragm pumps.
  • the metal effect color is constantly stirred to prevent sedimentation and over the Pumps kept in circulation. From the storage containers, the color is in the color pans conveyed under the rear cylinder into the printing unit of Dekortiefdruckmaschine.
  • the application of the metallic effect color takes place by means of An Hugheswalzen, which with a lasered and slightly compressible rubber coating are coated. By means of this will be picked up the paint from the paint tray and applied to the printing cylinder.
  • the rear cylinder is dipped directly into the color stand of the paint tray and picks up a color film on the surface and in the wells.
  • the rear cylinder is further passed by a squeegee, which the excess Metal effect color from the cylinder surface scratches and only a defined Quantity of paint left in a so-called cup.
  • the cylinder comes into the pressure zone.
  • the paper web that over Drives and guide rollers of the pressure zone of the printing unit is supplied by means of a Pressed with mechanical pressure roller pressed on the cylinder.
  • the force with which this press called roller presses the paper is usually 18 N / cm, depending on the application also a higher force.
  • a sodium aluminate solution (Water or water / waste mixture) in the gravure printing method by means of a Rear cylinder applied to the surface of Metallic horre.
  • This is a significantly increased pearlescent or metallic effect with simultaneous improvement Surface homogeneity HPL / LPM achieved.
  • Nacreous pigments are compounds in the form of feldspar or silicic acid (silicon dioxide), which are coated with titanium dioxide.
