Title:
WOODY SYNTHETIC RESIN MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/036021
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing woody synthetic resin materials of good appearance and high strength wherein woody material and thermoplastic resin material are uniformly mixed and there is little floating of woody material to the surface, even when relatively large woody raw materials are used in woody synthetic resins obtained by melt-mixing. The woody synthetic resin material comprising cellulose fiber-containing woody material and thermoplastic resin that solves the problem is obtained through a melt-mixing process of placing woody material and thermoplastic resin in a mixing device provided with a rotating blade and forming a gel by melting same using the frictional heat generated by the stirring thereof; a pressurized kneading process after the melt-mixing process wherein the gelled material is further kneaded under pressurized conditions; and a compression molding process after the pressurized kneading process of placing the material in a mold and compression-molding.
