VEHICLE-INTERIOR MATERIAL AND PRODUCTION METHOD THEREFOR

摘要

There is provided a vehicle-interior material, and in particular an instrument panel, which is thin, and which imparts a pleasant tactile sensation. In this integrated-urethane foam molded vehicle-interior material, a urethane foam layer is integrally molded between a resin skin material and a base material. The thickness of the urethane foam layer is 2.5-6.0 mm. The urethane foam layer is a foam body formed from a mixed solution comprising: a polyol mixture (P) which includes a polyol (resin) (A), a water-containing foaming agent (C), and a catalyst (D); and a polyisocyanate component (B). The foaming agent (C) content is 1.5-2.5 wt % when the total weight of (A) is used as a reference. The thickness of the resin skin material is 0.6-1.0 mm. The surface of the skin material is displaced at least 0.40 mm by a load of 10N, and is displaced 1.5-2.5 mm by a load of 40N.
