Abstract

The invention relates to a polyvinyl chloride (PVC) wood-plastic board and a preparation method thereof, belonging to the technical field of PVC boards. The PVC wood-plastic board is composed of the following raw materials in parts by weight: 20-70 parts of PVC resin powder, 0.1-5 parts of coupling agent, 2-5 parts of stabilizer, 0-20 parts of alkyl acrylate processing modifying agent, 0-20 parts of filling agent, 0-5 parts of lubricant, 0.5-5 parts of foaming agent, 0-10 parts of toughening agent and 20-70 parts of wood flour, wherein the total weight parts of the raw materials are 100 parts. The PVC wood-plastic board has the bulk density being not more than 700kg / m<3>, and has good flame resistance and smoke suppression property, high hardness and strong wood feeling; and the same as log, the PVC wood-plastic board has the properties of being nailed, drilled, planed, stuck and the like, is smooth and fine in surface, is waterproof, corrosion-resistant, fireproof and mildewproof, is not eaten by worms and is pollution-free.

Description

technical field [0001] The invention relates to a polyvinyl chloride wood-plastic board and a preparation method thereof, belonging to the technical field of polyvinyl chloride boards. Background technique [0002] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. Usually, polyvinyl chloride is used instead of the usual resin adhesive, and it is mixed with more than 30% of waste plant fibers such as wood powder, rice husk, and straw to form a new composite material. Wooden materials are processed by extrusion, molding, injection molding and other plastic processing techniques to produce panels or profiles. Wood-plastic has entered the national "Strategic Emerging Industries List" and is listed as a "new material". The state will help the green economy in terms of finance, taxation, finance, investment, etc., and at the same time increase the proportion of recycled products in government procurement....
