发明名称 Reaction injection moulding process for the production of a polyurethane skin layer
摘要 The present invention is directed to skin-integrated laminates and their use as vehicle interior articles, in which the laminates feel comfortable to the touch and have a high quality of external appearances. The invention also relates to a method for manufacturing these non-foaming polyurethane resins for use as design skins in vehicle interior articles and to a method for manufacturing a skin-integrated laminate from these non-foaming polyurethane resins, with both methods having increased productivity and lower cost, and without any adverse influence on the work environment. The non-foaming polyurethane resin forms a design skin surface by a reaction injection molding process, in which (I) a polyol mixture of (1) a polyol, (2) a chain extender which is 1-methyl-3,5-diethyl-2,4-diaminobenzene and/or 1-methyl-3,5-diethyl-2,6-dlwninobenzene, (3) a catalyst, and (4) optionally, an auxiliary agent, and (II) a polyisocyanate compound, are reacted. The surface hardness of the non-foaming polyurethane resin, as measured by an Asker A hardness meter, is from 30 to 70.
