Abstract

The invention discloses an easy-to-degrade environment-friendly composite material which is prepared from, by weight, 30-40 parts of wood powder, 20-26 parts of high-density polyethylene, 10-12 partsof vinyl-acrylic copolymer, 10-12 parts of polylactic acid, 23-29 parts of modified filler, 0.4-0.6 part of flame retardant, 0.2-0.3 part of antioxidant and 0.2-0.3 part of toughener. The invention further discloses a production process of the environment-friendly composite material. A wood-plastic composition material is obtained by taking high-density polyethylene and polyvinyl chloride as highpolymer substrates and wood powder as a main filler. Mechanical performance of the composite material is improved by adding the vinyl-acrylic copolymer and the modified filler; by adding the flame retardant, the composite material has good flame-retardant performance; by compounding a small amount of auxiliaries like the antioxidant and the toughener, related performance like antiaging performanceand toughness of the composite material is improved, and the wood-plastic environment-friendly composite material has excellent performance.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to an easily degradable environmentally friendly composite material and a production process. Background technique [0002] Resource shortage and environmental pollution are by-products of economic and social development. As the pace of economic development continues to accelerate, resource shortages and environmental pollution are also increasing, which have become stumbling blocks to economic and social development. Resource shortages increase the cost of development; environmental pollution damages air resources, water resources, and soil resources, which in turn damages human health and normal social life. Resource shortage and environmental pollution have become severe problems faced by countries all over the world, especially developing countries. Under such circumstances, making full use of renewable resources and developing environmentally friendly ...
