Wood-plastic composite section

Abstract

The invention discloses a wood-plastic composite section which comprises the following raw materials in percentage by weight: 40-50% of PVC (Polyvinyl Chloride), 0.1-1% of a foaming agent, 0.1-3% of acoupling agent, 0.1-3% of an antistatic agent, 0.1-3% of celestite and 40-60% of wood flour. The wood-plastic composite section disclosed by the invention has the characteristics of being mildew-proof, weather-resistant and antistatic.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a wood-plastic composite profile. Background technique [0002] Wood-plastic composite materials have the dual characteristics of wood and plastic, and this material has the advantages of corrosion resistance, wear resistance, no warping, stable size, good mechanical properties, and similar appearance to wood. Replacing wood with wood-plastic composite materials can not only reduce the demand for wood and save forest resources, but also turn waste into treasure through comprehensive development and utilization of waste resources, which has high economic and social benefits. [0003] Although wood-plastic composites have many advantages, due to the compounding of resin and wood powder, on the one hand, its mechanical properties such as toughness, impact strength and bending strength will be reduced compared to unfilled plastics. On the other hand, compared to ...

Problems solved by technology

[0003] Although wood-plastic composites have many advantages, due to the compounding of resin and wood powder, on the one hand, its mechanical properties such as toughness, impact strength and bending strength will be reduced compared to unfilled plastics. On the other hand, compared to natural wood, The density is about twice that of wood products, so it cannot be used as an ideal wood substitute, so its application fields are limited
