Problems solved by technology

However, conventional wood-plastic composite materials are dense, heavy, and inconvenient for transportation, installation, and maintenance. At the same time, they cannot absorb toxic and harmful gases in the environment. They are generally only used for outdoor flooring. The application of boards and other aspects has been greatly limited

Abstract

The invention relates to a foaming plastic wood composite material board and a preparation method thereof. The preparation method comprises the following steps: processing wood powder by using an aluminic ester coupling agent to obtain coupling agent modified wood powder; evenly stirring the coupling agent modified wood powder, plastic particles, alkali magnesium sulfate whisker and lead sulfate tribasic, extruding and pelleting to obtain composite material particles; evenly stirring the composite material particles, azodicarbonamide, composite foaming agent, terpene resin, ethylene bis stearamido and light stabilizer, and extruding to prepare the foaming plastic wood composite material board. The invention has the advantages of convenient production, low production cost, small use amount of plastics, environment friendliness, no aging or discoloration, no buckling deformation, low density, light weight and high impact strength, and has the function of adsorbing gas. The foaming plastic wood composite material board can be widely applied to households, office buildings and other buildings, can be manufactured to photo frames, picture frames, skirting and suspension plates, or can be used for manufacturing suspension cross beams, pergolas, and the like.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to a foamed plastic-wood composite material board and a preparation method thereof. Background technique [0002] Wood-plastic composite materials use hot-melt plastics, including polyethylene, polypropylene, polystyrene, etc., and their copolymers as adhesives, and use wood powder such as wood, crop straw, and crop shell powder as fillers. Composite materials formed by extrusion, compression molding or injection molding. The hot-melt plastic raw material can be industrial or domestic waste, and the wood powder can also be low-quality wood such as leftovers from wood processing and small-diameter wood. From the perspective of production raw materials, wood-plastic composite products slow down and avoid the pollution of plastic waste, and also avoid the pollution of the environment caused by the burning of crops. The production and use of wood-plastic composite materials will no...
