Abstract
The invention discloses a co-extrusion wood-plastic composite material with an antistatic surface. The material comprises an inner layer and a surface layer with which the surface of the inner layer is coated, wherein the surface of the inner layer is coated with the surface layer through a co-extrusion process; the inner layer is prepared from the following raw materials in parts by weight: 60 to70 parts of polyethylene, 20 to 30 parts of polypropylene, 80 to 90 parts of plantfiberpowder I, 2 to 4 parts of Arabic gum, 5 to 7 parts of an inorganic filler, 3 to 5 parts of a compatilizer, 2 to 4 parts of a lubricant I and 6 to 8 parts of a coupling agent; and the surface layer comprises the following raw materials in parts by weight: 12-14 parts of polypropylene, 3-5 parts of polyethylene, 7-9 parts of plantfiberpowder II, 1-2 parts of carbon black, 3-5 parts of carbon nanotubes, 2-4 parts of polyaniline, 2-4 parts of a silanecoupling agent and 0.6-0.8 part of a lubricant II. According to the wood-plastic composite material, the inner layer is wrapped by the anti-static surface layer, the components and content of the inner layer material are not affected, the anti-static capacity of the wood-plastic composite material is improved on the premise that the excellent performance of the wood-plastic material is not changed, the addition amount of anti-static components is small, and the production cost is low.
Description
technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a co-extruded wood-plastic composite material with antistatic surface. Background technique [0002] Wood-plastic composite (WPC) is a kind of green environmental protection material that has emerged in recent years. This composite material is composed of agricultural and forestry waste (such as wood powder, bamboo powder, bran powder and other plant fibers) and plastic in a certain proportion. It is obtained by adding corresponding additives under high temperature and high pressure, and its products are mainly used as wood substitutes. Compared with traditional wood, wood-plastic composite materials have the advantages of no warping, no cracking, good dimensional stability, easy processing, mildew resistance, no fear of insects, acid and alkali resistance, and low cost. In recent years, wood-plastic composite materials The material has been more and more widely u...
