Patent ID: 8143323

Claim:
A method for producing a laminate for a hood silencer of a vehicle, the method comprising: applying an adhesive to a surface of a substrate composed of a foam, the foam being a polyurethane foam having been obtained by reacting, foaming, and curing a raw material which comprises a polyol, a polyisocyanate, a blowing agent, and a catalyst wherein the polyol comprises, (i) a polymeric polyol in which a polyether polyol is graft-polymerized with vinyl monomer, (ii) a low molecular weight polyether polyol having a mass average molecular weight of from 400 to 1,000, in which a polyhydric alcohol is addition-polymerized with an alkylene oxide, and (iii) a high molecular weight polyether polyol having a mass average molecular weight of from 2,000 to 4,000 in which a polyhydric alcohol is addition-polymerized with an alkylene oxide; laminating a cover material on the adhesive; heating and pressurizing the laminate with a hot press molding machine for a predetermined period of time; compressing and shaping the laminate into a predetermined shape; and demolding the laminate from the hot press molding machine.
