Abstract

The invention relates to a lightweight plastic-wood composite sheet and a preparation method thereof. The preparation method comprises the following steps of: firstly stirring PVC particles and tribasic lead sulfate evenly in a stirred tank, and then adding wood flour, LDPE-g-GMA, hollow glass beads, chlorinated polyethylene, ethylene bisstearamide and hard fatty acid butyl ester to the tank, heating up and stirring evenly, cooling and taking out the mixture, and then stirring the mixture evenly with baking soda and citric acid at room temperature, extruding out and molding. The lightweight plastic-wood sheet has the advantages of convenient production and manufacture, high degree of mechanization in the production process, low production cost, low density, light weight, easy installation and maintenance, less use of timber and plastic, turning waste into treasure, being recyclable and not destroyed by insects, no aging and discoloration as well as cracking, no buckling deformation and high impact strength, with the function of adsorbing gas. The lightweight plastic-wood sheet can be applied to a plurality of occasions such as office buildings, hotels and home offices, can be made into products such as photo frames, picture frames, foot lines, and hoisting and fastening boards, and can also be used as suspended beams, pergolas, and the like.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to a light-weight plastic-wood composite material board and a preparation method thereof. Background technique [0002] In the fields or places such as decoration and garden corridors, various boards are often used in large quantities. Commonly used boards include wood, aluminum alloy, stainless steel, plastic, gypsum and other boards, but wooden boards are prone to moisture, mildew, and insects during use. or cracking, etc.; aluminum alloy plates are poorly modifiable, easy to deform, etc.; stainless steel plates are poorly modifiable, feel bad, bulky, expensive, etc.; plastic plates are prone to aging and discoloration, low strength, etc.; Reproducibility, etc. The existence of these defects often limits the use range and service life of these plates. [0003] Wood-plastic composite materials use hot-melt plastics, including polyethylene, polypropylene, polystyrene, etc., and...
