Wood-plastic plate and preparation method thereof

Abstract

The invention relates to a wood-plastic plate produced by using industrial by-product gypsum as a main raw material and a preparation method of the wood-plastic plate. The wood-plastic plate comprises the following raw materials in parts by weight: 55-65 parts of modified industrial byproduct gypsum, 35-45 parts of waste plastic particles, 0.1-1 part of a heat stabilizer and 0.1-1 part of a lubricant. The wood-plastic plate and the preparation method thereof disclosed by the invention have the following beneficial effects that 1, the defects of poor fireproof performance and high material comprehensive cost brought by wood-plastic plates produced in the prior art are solved; 2, industrial waste residues and waste plastic are mainly used as the raw materials, and thus the effective utilization of the wastes is realized, the material comprehensive cost is low, and quite high economic benefits can be produced, meanwhile, coal-fired power generation enterprises and chemical enterprises are also helped to digest the industrial by-product gypsum discharged for a long time.

Description

technical field [0001] The invention relates to a wood-plastic board and a preparation method thereof, in particular to a wood-plastic board produced by using industrial by-product gypsum as a main raw material and a preparation method thereof. Background technique [0002] The protection of forest resources, the lack of oil resources, and the need to purify the living environment force humans to use less wood and choose wood-plastic as companions for a long time. Therefore, human research and development and production of wood-plastic have become an inevitable trend. At present, scientific research and production units in all countries in the world are comprehensively and systematically developing and producing wood plastic, which has dual characteristics of wood and plastic, and a new material wood plastic that can replace wood. In the prior art, the production of wood-plastic boards is made of wood powder and fillers plus pvc plastic particles plus heat stabilizers and re...
