Abstract

The invention relates to a wood plastic composite material, in particular to a wood plastic composite plate capable of adsorbing toxic gas, and a preparation method thereof. The wood plastic composite plate is characterized by: adopting silane coupling agent modified wood flour as a raw material, mixing polyvinyl chloride, nano-magnesium oxide, active carbon and a heat stabilizer through stirringto obtain modified plastic particles; uniformly stirring the modified plastic particles, the modified wood flour, azobisformamide, a composite foaming agent, acrylic acid, chlorinated polyethylene and a ultraviolet absorber, followed by extruding, foaming and forming to obtain the wood plastic composite plate. The preparation method for the wood plastic composite plate is convenient. Compared to a common plastic plate, a gypsum board, a aluminum buckle plate and other wood plastic materials, the wood plastic composite plate provided by the present invention has characteristics of low density,light weight, high impact strength, low cost and toxic gas adsorbing, and can be made into a plurality of products such as photo frame, picture frame, ground pin line and the like, and can be widely applicable for a plurality of situations such as auditoriums and hotels, homes, office buildings, and the like.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a wood-plastic composite material plate capable of absorbing toxic gas and a preparation method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, wood-plastic composite materials with a wide range of raw materials, environmental friendliness, renewable and recyclable use have attracted more and more attention, and their application fields have continued to expand, such as automotive interiors, composite pipes , Railway sleepers, car box boards, cable protection pipes, manhole covers, car parts, pallets, packing boxes, planks, beams, open-air tables and chairs, benches, etc. Wood-plastic profiles can be handled with general woodworking techniques, can be cut with a circular saw, and fixed with nails or screws, and the nail-holding force is significantly better than other synthetic materials, and the m...
