Plastic-wood composite material capable of purifying air and preparation method thereof

Abstract

The invention discloses a plastic-wood composite material capable of purifying air and a preparation method thereof. The material is prepared from, by weight, 18-26 parts of polyethylene foam plastic,0.5-1.2 parts of a thermal stabilizer, 0.8-1.6 parts of a flame retarding agent, 0.5-0.9 parts of a photo-stabilizer, 0.3-0.8 parts of a foaming agent, 22-26 parts of paddy rice straw, 19-22 parts ofsugarcane residue, 0.5-0.8 parts of aluminate coupling agent, 12-14 parts of terpene resin, 9-18 parts of carbon fiber, 14-21 parts of basalt fiber, 18-24 parts of negative oxygen ion agent, 6-12 parts of TiO2, 12-16 parts of nano TiO2, and 5-8 parts of CaCO3 powder. The method includes steps of weighing the raw materials, and mixing and granulating the raw materials, and performing extrusive shaping to obtain the composite material. The composite material is high in strength, has good flame retarding effect, can purify air and has heat and sound insulation effect and anti-oxidizing function.

Description

technical field [0001] The invention relates to a composite material, in particular to a plastic-wood composite material 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, environmentally friendly, renewable and recyclable materials have attracted more and more attention. Wood-plastic composite materials can be used as packaging materials such as pallets and packing boxes, storage materials such as planks and beams, decoration and decoration materials such as houses, floors, and building templates, and outdoor tables, chairs, benches, etc. used in parks, stadiums, streets, etc. Leisure materials, automotive interior decoration materials, pipes, etc. Wood-plastic composite material has homogeneous material, more stable size than wood, less prone to cracks, and no wood knots, twill and other defects; it has ...

Problems solved by technology

But there are also some obvious deficiencies, such as non-flame retardant, in some occasions, such as picture frames, photo frames, roofing materials, etc., are limited in use, thus limiting their scope of use. Plastic-wood composite materials are used as decoration materials, which are easy to burn. Under normal circumstances, the oxygen index is only 17-19%, and it cannot self-extinguish after a fire
