Abstract

The invention discloses a highly filled wood-plastic foaming material and a preparation method thereof and belongs to the technical field of wood-plastic materials. The highly filled wood-plastic foaming material is prepared from the following raw materials: 100 parts of waste plastic, 20-30 parts of PVC particles, 70-85 parts of organic filler, 5-8 parts of inorganic filler, 1.5-1.8 parts of a coupling agent, 2-5 parts of maleic anhydride, 5-7 parts of a composite stabilizer, 1.0-2.0 parts of a composite foaming agent, 5-8 parts of a foaming aid, 2-3 parts of baking soda and 3-5 parts of epoxy soybean oil. The preparation method comprises the following steps of treating the organic filler with the coupling agent and a compatilizer and mixing the treated organic filler and other components and carrying out extrusion molding with an extruder. Compared with the existing wood-plastic composite material, the proportion of the filler in the wood-plastic foaming material is higher and thus the wood-plastic foaming material has good processing performance as well as lightweight, high specific strength, waterproof property, corrosion resistance, thermal insulation and the like.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic materials, and relates to a highly filled wood-plastic foam material and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new composite material with high performance and high added value, which is made of wood as the main raw material. In recent years, with the gradual intensification of environmental pollution, plastic materials that are difficult to degrade have been increasingly questioned, and some countries even explicitly restrict the production of certain plastic products. However, plastic products are still favored by consumers because of their light weight and low price. Therefore, wood-plastic composite materials combine the dual properties of plastic and wood, which can not only solve the problem of plastic pollution, but also provide consumers with Products with high performance and high added value are becoming more and more popul...
