MOULDING MATERIAL FOR EXTRUSION WITH FOAMING, METHOD OF ITS PRODUCTION, MOULDED WOOD-FILLED FOAM PLASTIC MADE FROM SAID MOULDING MATERIAL AND METHOD AND DEVICE FOR PRODUCING OF SAID FOAM PLASTIC

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to moulding material for extrusion with foaming and to process of its production. Besides, it relates to foamed synthetic wood-filled product made from moulding material, to method and device to this end. Moulding material for extrusion with foaming comprises foaming agent added to produce foamed synthetic wood-filled product by extrusion with foaming. Note here that said material contains wood flour with water content of 1 wt % and thermoplastic resin as well as 1-5 wt % with molecular weight of 300-1000 g/mol.;EFFECT: ruled out flaws in wood-filled foam plastics.;18 cl, 10 dwg, 3 tbl
