Abstract

The invention relates to the technical field of wood-plastic composite materials, and especially relates to an antiskid, flame-retardant and antistatic wood-plastic composite material and a preparation method thereof. The preparation method comprises the following steps: preparing a base material, preparing an antiskid agent, and mixing for preparing the composite material. The composite materialis prepared from polycarbonate resin, vegetable fibers, glass fibers, carbon fibers, a lubricant, an initiator, a flame retardant, a coupling agent, an antistatic agent, a compatibilizer and the antiskid agent. The composite material is formed by the base material and an antiskid layer sprayed on the surface of the base material, and the base material sequentially comprises a core latex, a shell latex and a sheath layer from the inside to the outside. The composite material has excellent antiskid, flame-retardant and antistatic properties.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to an anti-slip, flame-retardant and antistatic wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly composite material prepared by processing a certain proportion of wood fiber material, thermoplastic polymer resin and various additives through melt extrusion, injection molding or hot pressing compounding. It has the dual advantages of both wood and plastic. It not only has the wood-like appearance of wood but also has the advantages of water resistance, corrosion resistance and insect resistance of thermoplastics. Moreover, its dimensional stability is better than that of wood, and its hardness and modulus are higher than that of wood. Thermoplastics have a flexible production process and can be reprocessed and recycled. They have outstandin...
