Abstract

The invention discloses a wood-plastic material which comprises, by weight, 50.3% to 77% of poly ethylene (PE), propene polymer (PP), poly vinyl chloride (PVC) or acrylonitrile butadiene styrene styrene (ABS) resins; 8.8% to 25.1% of plant fibers; 0.9% to 3.0% of tribasic lead sulfate; 0.1% to 0.5% of zinc stearate; and 0.1% to 0.5% of calcium stearate; and further comprises dibasic lead phosphate, paraffins, stearic acid, acrylate copolymer, chlorinated polyethylene, titanium dioxide, chitin, chitosan and light calcium carbonate. According to the wood-plastic material, the chitin and the chitosan are added to improve the comprehensive performance of the wood-plastic material, the performance of the wood-plastic material achieves the performance of outdoor doors and windows manufactured by common pure polymer materials through a unique formula including mainly fibers, polymer materials, necessary processing agents, chitin and chitosan.

Description

technical field [0001] The invention relates to a wood-plastic material and a processing method thereof. The wood-plastic material and a production method thereof provide a green, energy-saving and environment-friendly building door and window material and a production method thereof. Background technique [0002] In the prior art, plant fiber-plastic composite materials (wood-plastic materials) are plant fibers (wood scraps, sawdust, branches, etc.), agricultural fibers (rice bran, straw, straw, flax stalks, fruit shells, etc.) and recycled plastics (PE, PP, etc.) , PVC, ABS, etc.) are environmentally friendly and recyclable materials; main products: floors, stair handrails, tables and chairs, furniture, fences, formwork, gussets, trays, pads, auto parts, offshore buildings, etc. Packaging, transportation and other industrial and civil products. It can replace wood and some plastic products, but when used in door and window products, some physical performance indicators of...
