PE foamed wood-plastic board and production method thereof

Abstract

The invention discloses a PE foamed wood-plastic board and a production method thereof and belongs to the technical field of composite materials. The PE foamed wood-plastic board comprises, by weight,30-60 parts of cotton straw powder, 40-70 parts of waste plastic, 5-8 parts of perlite, 10-13 parts of magnesium silicate, 3-6 parts of PE foamed material, 4-7 parts of antioxidant, 5-8 parts of stabilizer, 30-60 parts of silicon dioxide, 1-4 parts of impact-resistant modifier, 0.6-1 part of processing auxiliaries, 4-6 parts of binder, 0.1-0.4 part of auxiliary stabilizer and 0.5-0.9 part of lubricant. The PE foamed wood-plastic board and the production method have the advantages that the added stabilizer is a rare-earth stabilizer, weather-resistant rare-earth elements can absorb ultravioletof 230-320nm, and the impact-resistant modifier is acrylonitrile and butadiene random copolymer and can improve the low-temperature brittleness of the high-molecular material and improve the toughness of the high-molecular material.

Description

technical field [0001] The invention relates to a wood-plastic board and a preparation method thereof, in particular to a PE foamed wood-plastic board and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] With the development of social economy, plastic products have been widely used in various fields of production and life, and the resulting large amount of non-degradable waste has brought more and more attention to the problem of white pollution to the environment. . The increasingly serious environmental problems and the aggravation of the shortage of resources make the wood-plastic composite material, a new type of composite material synthesized by plant fiber and plastic, more and more people's attention. Among them, foamed plastic-wood composite materials have the functions of light weight, excellent dimensional stability, sound absorption, shock absorption, heat preservation, and convenient nailing and...

Problems solved by technology

At the same time, a large amount of wood product processing waste such as sawdust, wood shavings and other scraps, as well as a large number of crop fibers such as rice husk, wheat straw, cotton straw, etc. are often incinerated and wasteful, causing great pollution to the environment.

According to statistics, the amount of waste sawdust left over from wood processing in my country is more than several million tons every year, and the amount of other natural fibers such as rice bran is also tens of millions of tons. Traditional wood-plastic materials are prone to aging and poor brittleness after being used for a period of time. problem, use time is short
