Method for producing thermoplastic resin composite material containing FRP recycle

摘要

PPROBLEM TO BE SOLVED: To obtain a recycled material having excellent impact resistance by combining the ground material (the same as FRP recyclate) of a fiber-reinforced composite material (FRP) occurring as wastes with a polyolefin resin and a surface treating agent. PSOLUTION: The thermoplastic resin composite material is obtained by kneading and combining the FRP recyclate with a polyethylene or a polypropylene and the surface treating agent (a resin obtained by subjecting an ethylene-propylene copolymer or an ethylene-propylene-diene copolymer to graft polymerization with styrene or methacrylic acid) by a kneading extruder or a hot roll. A master batch of the FRP recyclate and the surface treating agent may be produced as an intermediate product and then kneaded and combined with the polyethylene or the polypropylene.
