Definitions

  • the resin-impregnated paper layers are impregnated with formaldehyde resin.
  • the resin used can preferably be a phenol-formaldehyde resin, melamine-formaldehyde resin or melamine-urea-formaldehyde resin.
  • the person skilled in the art knows how to use suitable previously known resin formulations to impregnate the paper layers.
  • the resin-impregnated paper layers contain a resin content of 40 to 60% by weight.
  • the resin-impregnated paper layers contain volatile components of 5 to 7% by weight. With such an impregnate, advantageous mechanical properties can be achieved while the risk of composite reinforcements in the form of bubbles is reduced.
  • the laminate can also comprise several splinter protection layers, whereby, for example, further resin-impregnated paper layers can be arranged between the individual splinter protection layers.
  • the several splinter protection layers can be identical to one another or can also be designed differently.
  • a further aspect of the invention relates to a method for producing a laminate which, as described, is particularly suitable for use in interior trim elements of vehicles.
  • the method comprises providing a first number of resin-impregnated paper layers, providing a second number of resin-impregnated paper layers, arranging a splinter protection layer between the first number of resin-impregnated paper layers and the second number of resin-impregnated paper layers, and treating the layers under the influence of pressure and temperature.
  • treating the layers comprises pressing at a pressure of 70 to 100 bar at a temperature of 140 to 160 °C.
  • the production method can comprise a coating step in order to provide the splinter protection layer with a coating as described herein.
  • Fig. 3 shows schematically the structure of a laminate according to a further embodiment
  • splinter protection layers 4 are provided, each arranged between paper layer arrangements 3a, 3b, 3c, which in this example also consist of 5 phenol-impregnated paper layers.
  • a splinter protection layer 4 is arranged between the paper layer arrangements 3a and 3b, and a second splinter protection layer 4 between the paper layer arrangements 3b and 3c.
  • the splinter protection layers 4 are identical to one another in this example, and are each formed by a 0.8 mm thick aluminum foil.
  • Fig. 4 shows schematically the structure of a splinter protection layer 4 according to a further embodiment.
  • the splinter protection layer 4 is formed by a three-layer aluminum foil, with individual phenol resin-impregnated paper layers 4b arranged between the individual aluminum layers 4a.

Abstract

La présente invention concerne un stratifié, plus particulièrement destiné à être utilisé dans des éléments de garniture intérieure de véhicules. Le stratifié comprend un premier nombre de couches de papier imprégnées de résine (3a, 3b, 3c) et un second nombre de couches de papier imprégnées de résine (3a, 3b, 3c). Une couche anti-éclats (4) est disposée entre le premier nombre de couches de papier imprégnées de résine (3a, 3b, 3c) et le second nombre de couches de papier imprégnées de résine (3a, 3b, 3c).
