Abstract

1380339 Moulding plastic substances &c. JOTO CHEMICAL CO Ltd 1 June 1972 [3 June 1971 1 Nov 1971] 25726/72 Heading B5A [Also in Division C3] A method for moulding thermoplastic resin compositions comprises mixing a thermoplastic resin with a filler at a true volume ratio of 1 to 0À5 to 1 to 1À5, the filler being preheated to a temperature at which the filler will have an amount of heat sufficient to heat the resin ingredient to its melting point and which is 50‹ to 200‹ C. higher than the melting point of the thermoplastic resin, and subsequently kneading the mixture under pressure. The resin may be a polystyrene, polyethylene, polypropylene, polyvinylchloride, AS or ABS resin or a polyamide. The filler may be sawdust or finely divided limestone, granite, andesite, calcium carbonate, silica, clay, asbestos, gypsum, alumina, cement or glass. Stabilizers and colorants may also be present, and organic fillers may be pretreated with a lubricant, e.g. a surface active agent, wax, lead stearate, epoxy resin or unsaturated polyester resin. Examples describe the mixing and extruding of polyethylene with (1) cedar wood sawdust and (3) finely divided limestone, and the kneading and moulding of polystyrene with (2) wood chips and (4) finely divided limestone.
