Woody thermoplastic resin composition

The present invention relates to a woody thermoplastic resin composition which is prepared by incorporating a certain specific additive into a woody thermoplastic resin comprising a thermoplastic resin and wood flour and which may be widely utilized in the fields where wood-like appearance is required. There is disclosed a woody thermoplastic resin composition which prevents the occurrence of rust on the metal surface in a molding machine and suppresses the generation of a volatile substance as encountered when a woody thermoplastic resin composed of a thermoplastic resin and wood flour was subjected to heat molding and processing.According to the present invention, a specific amount of dolomite is added to a woody thermoplastic resin composed of a thermoplastic resin and wood flour thereby there may be obtained a woody thermoplastic resin composition which has an effect to prevent the occurrence of rust on the metal surface in a molding machine during the molding and processing and to suppress the generation of a volatile substance.
