Abstract

The invention relates to an anti-termite-type wood plastic composite material and a preparation process therefor. The composite material comprises, by weight, 20-40 parts of plastic particles, 40-50 parts of plant fiber, 10-15 parts of compatilizers, 10-20 parts of masterbatches, 1-3 parts of lubricants, 5-10 parts of filling materials, 2-5 parts of pigments and 2-5 parts of functional auxiliaries. The preparation process comprises steps of the masterbatch preparation process and composite material preparation process. The anti-termite-type wood plastic composite material has advantages of inorganic and organic anti-termite agents, maintains the activity of anti-termite agents during the processing and usage of the wood plastic, thus the wood plastic composite material not only has anti-termite functions, but also has certain killing effects on termites, and the anti-termite effects last long. The problem of destruction of mechanical properties of products from inorganic anti-termite agents after addition of anti-termite agents is solved, and the wood plastic composite material has certain toughness intensity and anti-termite performances.

Description

Technical field [0001] The invention relates to the technical field of building decoration materials, and in particular to a termite-proof wood-plastic composite material and its preparation process. technical background: [0002] With the continuous expansion of the application range of wood-plastic composite materials, WPC is increasingly used as a wood substitute in building products, such as wood-plastic doors and windows, stairs, railings, wall panels, floors, tables and chairs, flower stands, wooden houses, wooden Pavilions, wooden bridges, wooden villas, landscape balconies, courtyard wooden structures, etc. As a new type of composite material, wood-plastic composite material has certain anti-termite properties than ordinary wood. However, it will still be attacked by termites when used in some areas with serious termite pests and diseases. Since wood plastic materials contain a certain amount of wood fiber fillers, they can be eaten away and damaged by termites just...
