Definitions

  • the invention relates to a method for impregnating for manufacturing highly abrasion-resistant laminate flooring materials used decorative paper, in which the decorative paper is first moistened with an amino resin and thereby impregnated as well as regulating the resin content.
  • the mass is applied by spreading rollers in the wet phase directly after Impregnate or applied in an intermediate drying stage.
  • the invention has for its object the disadvantages described above to avoid known manufacture of highly abrasion-resistant laminate flooring materials and to be able to produce highly abrasion-resistant decorative laminate flooring materials, whereby the decorative paper showing the surface structure evenly with particulate Corundum or aluminum oxide is coated without the surface of the so Floor materials produced has a graying.
  • One of the main differences of the method according to the invention is that that for impregnating the decorative paper and for applying the abrasion bodies such as Corundum or alumina particles used mass or dispersion is sprayed or applied in the nozzle principle.
  • the nozzle principle has the advantage over the roller application that the Abrasive bodies such as dispersion containing corundum particles constantly and before application completely circulated and thus moved more or less uniformly. Consequently There are no signs of sedimentation leading to irregularities. Therefore, the addition of viscosity-increasing substances or Substances are dispensed with. In fact, flow aids can even be used that cause a better distribution of the abrasion material like corundum, which in the press used to compress the material is advantageous.
  • Corundum or aluminum oxide there is no particular fine grain of the Corundum or aluminum oxide must be respected, but that corundum or other particulate abrasion material with significantly larger or coarser grain size can be used. This in turn means that relatively small amounts Corundum or other particulate abrasion material is needed to make higher To achieve abrasion values.
  • Another advantage of the invention is that you do not, as in the known Apply the mass or dispersion used for impregnation using Spreading rollers with relatively slow impregnation speeds of For example, 18 to 25 m / min must drive to a reasonably constant To ensure order, but that one with the inventive method, at to which the mass or dispersion is applied by means of nozzles, impregnation speeds can reach or realize between 40 to 50 m / min.
  • a special dispersion is first placed in a storage container with an agitator premixed. 200 kg melamine resin (Kauramin impregnating resin 786 from the company BASF), 10 kg of water, 1.5 kg of a wetting agent, 0.4 kg of a release agent and 1.5 kg Hardener (H 527 from BASF) stirred. Then add 80 kg Corundum with an average grain size of 135 ⁇ m. After stirring for 10 min 25 kg of 6-caprolactam and 0.9 kg of a commercially available silane coupling agent were added.
  • melamine resin Karl impregnating resin 786 from the company BASF
  • a standard impregnation channel from VITS is provided after the impregnation plant, with a push-in unit consisting of a spreader roller, a deflection roller, a nozzle gap with a collecting trough, a pair of metering rollers and wire doctor rollers, is arranged.
  • a decorative paper web with a basis weight of 70 g / m 2 is passed through the impregnation unit and the additional construction.
  • a resin application of 75 g / m 2 (determined after drying) is first set. When this value is reached, the nozzle is started and the special dispersion is applied.
  • a final mass of 155 g / m 2 is set via the second pair of metering rollers.
  • the paper treated in this way is passed through a dryer at a speed of 45 m / min. The residual moisture is 6.1%.
  • the decor paper is then placed on a HDF carrier board in a short-cycle press pressed (pressing temperature 180 ° C, pressing time 20 s). You get a brilliant surface, which meets the requirements of pr-EN 13329 and an abrasion value of IP Has 12,000.
  • particulate silicon carbide is used with a average grain size of 125 microns used. It will be a dark colored decorative paper used.
