Abstract

The invention relates to an environment-friendly thermoplastic wood-plastic composite and a production technology of the wood-plastic composite. The wood-plastic composite comprises the following raw materials in parts by weight: 15-25 parts of wood dust, 6-12 parts of bamboo dust, 35-45 parts of waste plastic, 10-15 parts of wheat straw, 6-15 parts of bagasse, 15-30 parts of soybean hull, 6-8 parts of peanut shell, 5-8 parts of egg shell, 6-12 parts of rice hull, 5-10 parts of sodium lauryl sulfate, 5-10 parts of crosslinked polyvinylpyrrolidone, and 3-8 parts of 1H,1H,2H,2H-perfluorooctyltriethoxysilane. The wood-plastic composite has good physical and mechanical properties, is high in bearing capacity, long in service life and high in water resistance, is not liable to deform, is not damaged by worms, does not generate fungi, is acid-alkali-resistant, corrosion-resistant, nontoxic, pollution-free and radiation-free, can be completely recovered and regenerated, meets an environment-friendly requirement, is a structural material, and can be sawn, planed and nailed; wood-plastic composites of various dimensions and specifications can be prepared and assembled according to customer demands; local damage of a product can be maintained and reconstituted; the flame resistance is adjustable; a color can be adjusted at random; the raw materials most adopt wastes; the price is low; secondary utilization of the wastes is achieved; an environment is protected; and an economic benefit is significant.

Description

Technical field [0001] The invention relates to an environment-friendly thermoplastic wood-plastic composite material and its production process. Background technique [0002] Wood-plastic composite material (WPC) is made of thermoplastic plastic and wood fiber or plant fiber. This material has the dual characteristics of wood and plastic. The thermal stretchability and water absorption are smaller than wood, and the dimensional stability is good. The abrasion and impact resistance are high, and the product can be recycled. However, the existing wood-plastic materials do not have diversified use effects and have poor flame-retardant effects, which seriously restricts the further development of wood-plastic materials. Summary of the invention [0003] The purpose of the present invention is to provide an environmentally friendly thermoplastic wood-plastic composite material and its production process in order to overcome the above shortcomings. [0004] The technical scheme of the ...
