Embodiment

[0012] A straw wood-plastic composite material, the raw materials of which include in parts by mass: 30 parts of PE recycled material, 65 parts of straw powder, 5 parts of maleic anhydride grafted polypropylene, 4 parts of OptiPak lubricant, and 2 parts of lead salt composite stabilizer , 2 parts of ethylene-vinyl acetate copolymer, 1 part of ultraviolet absorber, 5 parts of nano-calcium carbonate, 2 parts of ethanol, 1 part of acetic acid, and 3 parts of pigment.

[0013] Further, the straw powder includes rapeseed straw, rice straw, and rice husk.

[0014] Further, the ultraviolet absorber is a composite ultraviolet absorber of UVP-327 and RMB, and the mass ratio of UVP-327 to RMB is 4:6.

[0015] The processing method of the straw powder of the present invention is as follows: taking straw powder, ethanol and acetic acid according to the ratio, placing them in a high-speed mixer, mixing them uniformly, standing still for 3 hours, and then drying until the water content is w...

Abstract

The invention discloses a compound straw and wood plastic material. The compound straw and wood plastic material is prepared from, by mass, 25-30 parts of PE return material, 55-65 parts of straw powder, 4-6 parts of maleic anhydride grafted polypropylene, 4-6 parts of OptiPak lubricant, 1-2 parts of lead salt compound stabilizer, 1-2 parts of vinyl-vinyl acetate copolymer, 1-1.5 parts of ultraviolet light absorber, 3-5 parts of nano calcium carbonate, 1-2 parts of ethanol and 0.5-1 part of acetic acid and 2-3 parts of pigment. The compound straw and wood plastic material is prepared by adopting the abandoned crop straw and the PE return material, crop straw and plastic waste are fully utilized, the cost is saved, the pollution problem brought by straw burning is relieved, straw powder is pretreated by adopting the ethyl alcohol and the acetic acid, and the compatibility of straw powder and PE is improved.

Description

technical field [0001] The invention relates to a composite material, in particular to a straw wood-plastic composite material. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly composite material product. It is made of waste plastic, wood fiber and additives through granulation equipment. Because it has the advantages of both wood and plastic, it is widely used. . [0003] As a by-product of agricultural production, crop straw has a large output and wide distribution. Due to the lack of reasonable and effective use of straw, crop straw has become a new source of rural environmental pollution in recent years. Every summer and autumn, a large amount of wheat and corn stalks are burned in the fields, producing a large amount of smoke and causing serious air pollution across the country. Contents of the invention [0004] The purpose of the present invention is to provide a straw-wood-plastic composite material, which is...
