Abstract:
A woody thermoplastic resin composition comprising (A) 100 parts by weight of a thermoplastic resin, (B) 5 to 150 parts by weight of wood flour and 0.01-20.0 parts by weight based on the total amount of (A) and (B) components, of a dolomite,wherein said dolomite is selected from the group consisting of: (A) light burned dolomites prepared by heating at a temperature of 900 to 1,000Â° C. a magnesium carbonate-calcium carbonate complex salt in which the weight ratio of magnesium to calcium is 5:95 to 95:5 in terms of MgO:CaO; and (B) dolomites subjected to surface treatment with a surface treatment agent selected from the group consisting of organic acids, metal salts of an organic acid, polyhydric alcohols, silane coupling agents, aluminum coupling agents, phosphate coupling agents, anionic surfactants, cationic surfactants, nonionic surfactants, polymeric dispersing agents, and mixtures thereof.
