Abstract

The invention discloses a PVC wood-plastic foam board which is prepared from the following raw materials in parts by weight: 20-30 parts of PVC resin, 8-17 parts of polypropylene, 15-22 parts of bamboo powder, 6-14 parts of modified kaolin, 10-20 parts of waste ceramic powder, 5-10 parts of vitrified micro bubbles, 3-6 parts of ammonium polyphosphate, 2-5 parts of aluminum oxide, 2-3 parts of fumed silica, 1-2 parts of ultraviolet light absorbent, 2-4 parts of sodium bicarbonate, 2-3 parts of lubricant, 1-2 parts of impact modifier, 2-3 parts of composite stabilizer, 1-4 parts of coupling agent and 2-5 parts of foaming agent. The PVC wood-plastic foam board has the advantages of high mechanical strength, strong impact resistance and relatively high hardness and can be widely applied to thematerials in home decoration, buildings and the like.

Description

technical field [0001] The invention belongs to the technical field of PVC wood-plastic boards, and in particular relates to a PVC wood-plastic foam board and a preparation method thereof. Background technique [0002] With the acceleration of industrialization, my country's timber resources are becoming more and more scarce, which cannot meet the needs of the market. Wood-plastic composite material is a kind of thermoplastic polymer composite material filled with wood powder, wood fiber or other plant fibers. It has the advantages of both wood and plastic. It can replace wood as a building material in the fields of home decoration and construction. Wood-plastic, due to its advantages of environmental protection, high molding efficiency, waterproof, and good weather resistance, has developed faster and faster in recent years, but due to its low mechanical strength, poor impact resistance, and low hardness, it has been used in many industries is restricted.
