Preparation of multifunctional wood-plastic composite material

Abstract

The invention relates to a wood-plastic composite material which can be applied to the floor, tableware, daily necessities, Profile, automotive, and other fields. In the invention, it adds the anion additives, nano-photocatalyst, nano-fillers into the composite material to make the wood-plastic composite material achieves the function such as release negative ions, antibacterial bacteriostasis, removing odor, clean air, flame retardant.

Description

technical field [0001] The invention belongs to the fields of polymer material modification, chemical industry, composite material, material processing, environmental protection, rational utilization of resources and the like, and has wide application value. Background technique [0002] Wood is derived from renewable resources and is a porous composite material composed of cellulose, hemicellulose, lignin and other organic substances. As an industrial material, it has good environmental coordination and plays a very important role in the national economy. effect. However, wood has disadvantages such as perishable, flammable, susceptible to insects, low absolute strength, easy to absorb water and moisture, and cause large dimensional deformation, which limits its processing and application to a certain extent. In recent years, the world's forest resources are becoming increasingly depleted, social awareness of environmental protection is increasing, and at the same time, hi...
