PROBLEM TO BE SOLVED: To provide a polyurethane foam for frame laminate, which can exhibit an excellent adhesive strength and can prevent discoloration. SOLUTION: This polyurethane foam for the frame laminate, produced by reacting, foaming and curing polyurethane foam raw materials comprising a polyol, a polyisocyanate, a foaming agent and a catalyst, is characterized by compounding at least one organic compound selected from benzothiazole-based compounds and dithiocarbamate-based compounds and an endothermic agent in the polyurethane foam raw materials. The organic compound has preferably a decomposition temperature of 170 to 220°C and is preferably compounded in an amount of 0.1 to 2.0 pts.mass per 100 pts.mass of the polyol. The endothermic agent is preferably a sulfate hydrate and is preferably compounded in an amount of 3.0 to 20.0 pts.mass per 100 pts.mass of the polyol. COPYRIGHT: (C)2008,JPO&INPIT |
