Abstract

The invention discloses a high-strength corrosion-resistant wood-plastic composite material and a method for preparing the same. The high-strength corrosion-resistant wood-plastic composite material comprises, by weight, 25-30 parts of wood powder, 30-35 parts of ABS (acrylonitrile butadiene styrene), 20-25 parts of PVC (polyvinyl chloride), 3-5 parts of maleic anhydride grafted polyethylene, 1-2 parts of ACR (acrylic ester), 10-15 parts of 800-mesh feldspar powder, 0.3-0.7 part of stearate, 0.8-1.5 parts of terpene resin and 1-3 parts of auxiliaries. The high-strength corrosion-resistant wood-plastic composite material and the method have the advantages that the wood-plastic composite material prepared by the aid of the method is good in strength, corrosion resistance and aging resistance and excellent in processability and long in service life, and accordingly the high-strength corrosion-resistant wood-plastic composite material and the method have excellent application prospects.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a high-strength, corrosion-resistant wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of composite material that has emerged in recent years at home and abroad. It is made of biomass fibers (wood chips, sawdust, rice bran, crop straw) and plastics (PP, PE, PVC, PS) and related additives. It is a kind of green environmental protection material obtained by extrusion, molding, injection molding and other processing techniques. In recent years, wood-plastic composite profiles, as a new type of environmentally friendly material, have been widely used in building materials, furniture, logistics packaging and other industries due to their dual characteristics of wood and plastic. At present, the wood-plastic composite materials in the prior art still have some defects, such as: i...
