POLYURETHANE LAMINATION RESIN, LAMINATE CONTAINING THE POLYURETHANE LAMINATION RESIN, AND SKIS OR SNOWBOARDS CONTAINING THE LAMINATE

摘要

The present invention relates to a method for producing a polyurethane lamination resin, wherein a) an isocyanate prepolymer based on diphenyl-methane diisocyanate is mixed with a difunctionally started polyether, b) polyphenylene polymethylcne polyisocyanate, c) trifunctionally started polyetherpolyol having a mean molecular weight of 350 to 600 g/mol, d) a thermoactivatable, blocked catalyst, e) optionally chain-lengthening agents and/or cross-linking agents, f) optionally water-absorbent materials, and g) optionally other additives to form said polyurethane lamination resin. Furthermore, the present invention relates to a polyurethane lamination resin, obtainable by such a method, and to the use of such a polyurethane lamination resin to produce laminates and skis or snowboards, containing said laminate.
