Abstract
Provided is a method for producing a resin molded article including an introducing step of introducing a plurality of resin foam particles and a heat medium substance into a forming mold, and a molding step of, after the introducing step, heating the forming mold to a temperature at which the heat medium substance can be vaporized, thereby obtaining a resin molded article including the plurality of resin foam particles.
Claims16
A method for producing a resin molded article, comprising:
- introducing a plurality of resin foam particles, a thermoplastic resin composition, and a heat medium substance into a forming mold;
- and
- after the introducing, a molding process of heating the plurality of resin foam particles and the thermoplastic resin composition by heating the forming mold to a temperature at which the heat medium substance can be vaporized to allow the heat medium substance to vaporize in the forming mold, thereby obtaining a resin molded article that is a resin composite in which the plurality of resin foam particles are dispersed in a matrix composed of the thermoplastic resin composition,
- wherein
- the thermoplastic resin composition comprises a polyolefin-based resin or a polystyrene-based resin, and
- the plurality of resin foam particles are composed of a resin composition comprising a polyolefin-based resin.
