Abstract

The invention relates to a high-hardness wood-plastic building template and a preparation method thereof, which belong to the technical field of polyvinyl chloride plates. The 100 parts by weight of high-hardness wood-plastic building template comprises the following raw materials in parts by weight: 20-50 parts of polyvinyl chloride resin powder, 1-4 parts of a coupling agent, 2-5 parts of a stabilizing agent, 1-15 parts of an acrylic alkyl ester processing modifier; 1-15 parts of a filling agent, 1-4 parts of a lubricant, 1-4 parts of a foaming agent, 1-8 parts of a toughening agent, 30-50 parts of wood flour, and 5-10 parts of a reinforcing agent. According to the invention, the plate stacking density is less than or equal to 700 kg / m<3>, so that the building template is good in flame retardancy and smoke suppression, meanwhile, the building template is high in hardness and strong in wood texture; and just like raw woods, the building template also has the properties that the template can be nailed, drilled, planed and adhered and the like, the surface of the template is smooth and fine, and the template is water-proof, corrosion-resistant, fireproof, mould-proof, moth-preventing, and pollution-free.

Description

technical field [0001] The invention relates to a high-hardness wood-plastic building template 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 procu...
