Abstract: The invention discloses a method for manufacturing a wood-plastic blended composite material product. 1～ 1. 0 Will not dry wood powder 100 parts, plastic particles 30 to 100 parts, compatibilizer 0. 5 ~ 10. 0 parts, coupling agent 0. 5 ~ 5.0 parts, antioxidant 0. 1 ~ 1. 0 5份、油墨。 0. 1～2. 0份。 At the same time adding granulation extruder extrusion granulation, the resulting pellets used to squeeze Extrusion machine, after cooling stereotypes, traction, cutting, modified into wood-plastic products. The advantages of the present invention are as follows: (1) The wood flour can be directly added into the extruder without the need of drying, and the plastic particles and auxiliaries can be blended and extruded to simplify the processing flow and improve the production efficiency; (2) In addition to using wood waste and In addition to agricultural straw, bamboo processing waste can also be used, and raw material sources are abundant; (3) Wood flour is uniformly dispersed in the plastic matrix and the filling amount is high, and the product is close to the texture of the logs; (4) The wood fiber morphology is unchanged, and the product performance is excellent , High impact strength and tensile strength; (5) The obtained wood-plastic products can be recycled, green and environmental protection.
