Problems solved by technology

However, traditional plastic materials are difficult to meet the needs of society, but people soon realized that the modification of plastic filling can not only reduce production costs, but also improve the performance of products
The production cost of traditional composite foam board materials is relatively high, and at the same time, it also contains certain toxic substances inside. Even though it has the characteristics of high static bending strength and high elastic modulus, consumers will still give up buying due to concerns about the safety of materials. Therefore, it affects the sales of the product

Abstract

The invention discloses a wood-plastic composite foaming material and a preparation method thereof, and belongs to the technical field of composite materials. The wood-plastic composite foaming material comprises the following components in parts by weight: 20-40 parts of corn straw powder, 30-50 parts of waste plastic, 10-12 parts of alumina fibers, 13-15 parts of fluorite, 2-4 parts of a foamingmaterial, 3-5 parts of an anti-oxidant, 4-6 parts of a stabilizer, 40-60 parts of a silicon dioxide, 7-9 parts of an impact resistance modifier, 8-10 parts of a processing aid, 6-8 parts of an adhesive, 1-3 parts of an auxiliary stabilizer and 2-5 parts of a lubricant. Through adding the stabilizer which is an organic tin stabilizer, the wood-plastic composite foaming material is efficient, has high transparency and good heat resistance, and is capable of resisting vulcanized pollution. The preparation method is capable of preventing toxic substances in a traditional wood-plastic composite foaming material from endangering human health, utilizing wastes, reducing environmental pollution and reducing production cost of enterprises.

Description

technical field [0001] The invention relates to a wood-plastic composite material and a preparation method thereof, in particular to a wood-plastic composite foam material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] Wood-plastic composite material, referred to as WPC, is a kind of biomass fiber and thermoplastic resin as the main raw materials, and then adding some additives, colorants, coupling agents and lubricants, and then processed by extrusion molding, compression molding, injection molding, etc. environmentally friendly composite materials. Wood-plastic composite material is a kind of basic material that covers a wide range of products and has a variety of morphological structures. It has excellent water resistance and corrosion resistance, and can be recycled. It greatly embodies our country's concept of developing "circular economy" and building a "conservation-oriented society". Vigorousl...
