摘要:
This invention provides composite material compositions comprising wastepaper, a thermoplastic resin and/or other additive(s), said compositions having higher heat resistance, flame retardancy and mechanical strength and smaller linear shrinkage in molding than the conventional compositions of synthetic resins alone or blended with woodmeal or an inorganic filler. There is also provided a method of producing said compositions comprising a wastepaper crushing step, a step of mixing crushed wastepaper with a thermoplastic resin and/or other additive(s) while drying said wastepaper, a blend melting step, a blend kneading step and a blend granulating step. In an embodiment of this invention, scraps of moldings from the composite material compositions using wastepaper may be mixed with wastepaper, a thermoplastic resin and/or other additive(s) and similarly treated and molded into a new composition.
