Problems solved by technology

Since WPC has both the water resistance and anti-corrosion characteristics of plastic and the texture of wood, it has become a kind of outdoor building material with excellent performance and very durable; WPC material is waterproof, moisture-proof, high environmental protection, and can replace wood in large quantities It is a low-carbon, green, recyclable and renewable ecological material with great development prospects. However, due to the fact that wood-plastic materials are often easily worn, broken, and deformed during actual use, the use of products made of this wood-plastic material Significantly reduced performance and shorter lifespan

Abstract

The invention discloses a plastic wood material. The weight percentage of each component is: 46.8-63.3% of plastic, 18.9-29.6% of wood flour, 5.4-9.7% of carboxymethyl cellulose sodium, 2.8-5.1% of copper acetate, 1.6-1.9% of tea saponin, 3.3-4.8% of powdered steatile, 0.8-1.2% of toner, 0.8-1.2% of a lubricant, 1.5-2.2% of a compatibilizer, 0.5-0.7% of a manganese compound, 0.2-0.6% of borax, and0-12.5% of a plastic wood recycled material, wherein the total weight percentage is 100% . The plastic wood material achieves the enhancement of the strength, hardness and wear resistance of the wood-plastic material by improving a formula. The wood-plastic material of the invention has good impact strength, pressure resistance, deformation resistance, wear resistance and low water absorption, isnot easy to be worn, broken, warped and deformed, and can be widely applied to various occasions.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a wood-plastic material and a preparation method thereof. Background technique [0002] Wood-plastic materials, also called wood-plastic materials, are mainly made of plastics such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC) and other recycled waste plastics as raw materials, and processed by adding wood powder and other plant fibers. . Since WPC has both the water resistance and anti-corrosion characteristics of plastic and the texture of wood, it has become a kind of outdoor building material with excellent performance and very durable; WPC material is waterproof, moisture-proof, high environmental protection, and can replace wood in large quantities It is a low-carbon, green, recyclable and renewable ecological material with great development prospects. However, due to the fact that wood-plastic materials are often easily worn, broken, and d...
