Abstract

A foamed porous wood-plastic composite is prepared from, by weight, 35-45 parts of high-density polyethylene, 40-50 parts of wood powder, 5-10 parts of inorganic micro powder, 0.5-2 parts of a compatilizer, 1-2 parts of a flame retardant, 2-5 parts of a plasticizer, 1-2 parts of a lubricating agent, 0.5-1.5 parts of a coloring agent, 0.5-2 parts of an antibacterial agent, 1-2 parts of a foaming agent and 1-2 parts of a foaming stabilizing agent. According to the foamed porous wood-plastic composite, the raw materials are mixed in a material mixer according to the formula proportion, and all the components are dispersed to be uniform and then put into a double-screw extruder for melt extrusion and granulation; the preparation procedure is simple, the process is simple and controllable, the production efficiency is high, and the prepared foamed porous wood-plastic composite is superior in performance and high in cost performance and has the wide market application prospect.

Description

technical field [0001] The invention belongs to the field of wood-plastic composite materials, and in particular relates to a foamed porous wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a kind of compound made by blending thermoplastic polymer with wood chips or wood powder, plant fiber powder, etc., adding various processing aids, kneading at high temperature, and then extruding, molding, injection and other molding processes. An environmentally friendly composite material. The material has low cost, can be widely used in construction, transportation, light industry and other departments, and has broad market prospects and environmental protection value. Wood-plastic composite materials also have some shortcomings. The density of wood-plastic composite materials is usually twice that of solid wood materials, and the price is relatively high, so its application range is greatly limited. Th...
