摘要

The wood-synthesized component of the present invention mixes, gels and kneades the thermoplastic resin molding 25 to 80% by weight with respect to 20 to 75% by weight of cellulose crushed matter having an average particle diameter of 20 mesh or less with a water content of 15% by weight or less. It consists of grinding | pulverizing and establishing it to the particle size within 10 mm.;In the method for preparing the wood composite component of the present invention, the water content is less than 15% by weight, and the thermoplastic resin molding material 25 to 80% by weight is simultaneously applied to the cellulose-based shreds having an average particle diameter of 20 mesh or less. It comprises at least the step of mixing by braid, gel-kneading by frictional heat, cooling, pulverizing and sizing within a particle diameter of 10 mm.;In addition, the apparatus for producing wood synthetic powder according to the present invention may simultaneously mix 25 to 80% by weight of thermoplastic resin molding materials with respect to 20 to 75% by weight of cellulose crushed matter having an average particle diameter of 20 mesh or less with a water content of 15% by weight or less. A flow mixing kneading means having a square impact braid for gelation kneading by frictional heat, a cooling assembly means having a braid inside the cooling kneading kneaded kneading material, and having an inlet and an outlet of cooling water in the jacket; It consists of sizing means for squeezing the granulated wood powder cooled and assembled within the particle diameter of 10mm.
