RECLAIMED FRP-BASED THERMOPLASTIC COMPOSITE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a reclaimed FRP-based thermoplastic composite composition obtained by utilizing a waste FRP, having heat flow characteristics moldable by a general-purpose molding method of a resin material such as an injection molding method and an extrusion molding method, providing an FRP-reclaimed product keeping the sufficient mechanical properties even when the mixed proportion of the waste FRP is≥50 pts. wt. and effective for practical application of the material recycle of the waste FRP.

SOLUTION: The reclaimed FRP-based thermoplastic composite composition is obtained by mixing a pulverized waste FRP with a polyolefin-based resin and a functional binder comprising a copolymer or terpolymer having an epoxy group in the main chain of the polymer to form a chemical bond at the interface of the waste FRP and the polyolefin-based resin, and compounding the mixture by melting and kneading.
