Japanese Patent JP5972481

B2

Provided is a method for producing a foam-molded article that has excellent rigidity, impact resistance, and external appearance, and is capable of ductile fracture. The method for producing a foam-molded article of the present invention includes a kneading step of melt-kneading a resin composition in the presence of a foaming agent, the resin composition containing 100 parts by weight of a propylene-based resin, 1 to 30 parts by weight of an aromatic vinyl-based thermoplastic elastomer, and 1 to 30 parts by weight of an inorganic filler, and a foaming step of injecting the resin composition in a molten state into a mold, to foam and mold the resin composition. The method can produce a foam-molded article that has excellent rigidity, impact resistance, and external appearance, and is capable of ductile fracture.
