Wood plastic composite dalle and preparation method thereof

Abstract

The invention relates to a wood plastic composite, in particular relating to a wood plastic composite dalle and a preparation method thereof. The preparation method comprises the following steps: mixing polrvinyl chloride particles, nano attapulgite, calcium carbonate powder, short glass fibers, terpene resin, chlorinated polyethylene, tribasic lead sulfate and stearate, extruding and pelleting, so as to obtain a modified plastic particle; evenly mixing the modified plastic particle with wood poader and azodicarbonamide and pelleting so as to obtain a wood plastic particle; and finally, extruding the wood plastic particle, foaming and forming so as to obtain the wood plastic composite dalle. The wood plastic composite dalle can be manufactured conveniently, and has the advantages of high production mechanization degree and less required labor. Compared with the common plastic dalle, the wood plastic composite dalle provided by the invention has the following advantages: the plastic dosage of the wood plastic composite dalle is reduced, and wood plastic composite dalle is environment-friendly, and has the characteristics of high modulus, low density, creepage resistance and low product cost. Compared with the gypsum boards, aluminum plates and the like, the wood plastic composite dalle provided by the invention has the following advantages: the cost is lower, the density is smaller, the installation and maintenance are more convenient, and the wood plastic composite dalle has an air purification function. The wood plastic composite dalle can be widely applied to various scenes such as buildings and houses, home offices and the like.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a wood-plastic composite decorative board 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. Wood-plastic composite materials can be used as packaging materials such as pallets and packing boxes, storage materials such as planks and beams, and leisure materials such as outdoor tables, chairs, and benches used in parks, stadiums, streets, 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 the processability of thermoplastics, extrusion, injection molding and other processes can be used for molding, and e...

Problems solved by technology

But there are also some obvious deficiencies, such as high density, high price, inability to absorb toxic and harmful gases, etc., so its scope of use is mostly limited to outdoor use, but it has not been fully applied in interior decoration.
