PVC plastic wood composite material

Abstract

The invention discloses a PVC plastic wood composite material. The composite material is prepared from, by mass, 100 parts of PVC aggregates, 20-30 parts of waste PVC, 40-55 parts of wood powder, 0.1-0.3 parts of methyl methacrylate, 0.3-0.5 parts of an AC foaming agent, 1-3 parts of a plasticizer, 1-5 parts of a foaming regulator, 1-3 parts of a calcium and zinc stabilizer, 0.2-0.5 parts of stearic acid, 10-20 parts of lightweight active carbonic acid, 7-12 parts of a titanate coupling agent, 7-12 parts of maleic anhydride , 1-3 parts of an antioxidant, 1-7 parts of titanium dioxide, 0.5-2.5 parts of carrageenan and 1-3 parts of kaolin. The above ratio of raw material components is adopted to optimize the color turbidity problem of present plastic materials, so the prepared PVC plastic wood material has very good color, the interface combination among raw materials is improved, the dosage of the wood powder is improved, and performances of the material are optimized.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a PVC plastic-wood composite material. Background technique [0002] WPC, as the name suggests, is a combination of solid wood and plastic. It not only maintains the affinity of solid wood, but also has good moisture-proof, water-resistant, acid and alkali resistance, anti-fungal, anti-static, anti-moth and other properties. A series of wood-plastic composite materials produced from waste such as sawdust, straw, and waste plastics are gradually entering the fields of decoration and construction. At present, the main product is PVC wood-plastic material obtained by combining wood chips and PVC. However, due to the poor compatibility of the system after adding wood powder, the strength of the product is reduced and the appearance is not smooth. Therefore, the amount of wood powder in general PVC wood-plastic materials is about 20% of that of PVC. [0003] ...

Problems solved by technology

However, since the material is brand-new PVC, the cost is relatively high, and in the process of processing, due to the absence of lubricant, the temperature of the joint point between the raw materials increases, and the energy consumption increases. Under the background of modern green chemical industry, it is obviously not the best. Excellent solution, with room for optimization and direction for improvement
