METHOD FOR MANUFACTURING LAMINATE

WIPO Patent Application WO/2022/091750

A1

A method for manufacturing a laminate, wherein the laminate is formed by integrally laminating a foamed-particle molded body a that is composed of foamed particles A and that has interconnected gaps, and a foamed-particle molded body b that is composed of foamed particles B and that has interconnected gaps, the difference [Pb-Pa] between the porosity (Pa) of the foamed-particle molded body a and the porosity (Pb) of the foamed-particle molded body b is 5% or more, and the foamed particles A and the foamed particles B satisfy formulae (1) to (3). (1) The difference [dB-dA] between the average pore diameter dA of through pores of the foamed particles A and the average pore diameter dB of through pores of the foamed particles B is 0.3-2 mm. (2) The average outer diameter DB of the foamed particles B is 3.5-5 mm. (3) The difference [DB-DA] between the average outer diameter DA of the foamed particles A and the average outer diameter DB of the foamed particles B is -0.3 to 2 mm.
