Problems solved by technology

Therefore, research on the effects of formulation and processing parameters on the properties of wood-plastic composites needs to be strengthened.
Although domestically produced wood-plastic composite materials have many advantages, there are still deficiencies so far, such as easy to scratch, easy to oil, low flame retardancy, poor aging resistance, etc.

Abstract

The invention relates to a wood-plastic composite material containing natural vegetable fibre, relating to the technical field of novel materials. The wood-plastic composite material containing natural vegetable fibre disclosed by the invention is composed of 20-80% of modified wood and / or bamboo plant fibre, 10-40% of waste polyvinyl chloride, 1-10% of ammonium polyphosphate, 1-5% of paraffin, 1-10% of lubricating agent, 1-10% of mildewproof agent and 1-10% of corn starch. According to the invention, wastes are used as production raw materials; produced products have the characteristics of being higher in intensity and hardness, good in fire resistance, free from formaldehyde and easy to recycle; corn starch and ammonium polyphosphate are combined, therefore, the fire resistance of the material is greatly increased; and the wood-plastic composite material containing natural vegetable fibres is a novel green environment-friendly material.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a natural plant fiber wood-plastic composite material. Background technique [0002] my country's logging residues and timber residues account for about 40% of forest biomass. 3 According to calculations, my country will produce about 110 million tons of logging and timber residues every year. In addition, the processing residue is as high as 32.1 million m3 based on 34.4% of logs 3 annual output. At present, although the utilization of the "three leftovers" of forestry has attracted people's attention, the level of development in the world is not balanced. The comprehensive utilization rate of timber in developing countries such as China is only 50% to 60%, while that in developed countries has reached 80% to 90%. The current situation of development and utilization of forestry "three leftovers": forestry "three leftovers" usually have low accumulation density, large v...
