FOAMED RESIN LAMINATE SOUND INSULATION BOARD AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: Provided is a foamed resin laminate sound insulation board capable of exhibiting sound proofing performance, which is free from restrictions of shape, applicable place and weight, thinned as the whole laminated plate to enhance plastic workability such as press work. CONSTITUTION: The foamed resin laminate sound insulation board(1) is a laminated plate comprising an unfoamed foamable resin(3a) to be foamed at a foaming temperature by heating and a hard plate(2). The foaming temperature of the first foamable resin is differed from that of the second foamable resin. The laminated plate is formed by laminating a non-foamable material not foamable by heating, the foamable resin, and the hard plate in this order.
