Problems solved by technology

According to statistics, in 2016, the total output of coffee in my country's Yunnan Province alone reached 140,000 tons. During the initial processing of coffee, a large number of processing residues will be produced, such as peels, pectin, bean shells and waste water; coffee bean shells, coffee beans As a kind of waste in the production process, if the shell is not treated scientifically and effectively, it will not only cause waste of resources, but also bring serious pollution to the environment

Abstract

The invention discloses a novel environment-friendly wood plastic material and a preparation method thereof and relates to the field of novel environment-friendly materials. The novel environment-friendly wood plastic material is prepared from the following raw materials in parts by weight: 22-26 parts of polyvinyl chloride resin, 12-18 parts of modified coffee shell powder, 24-32 parts of straw powder, 5-10 parts of nano titanium dioxide, 8-15 parts of nano calcium carbonate, 1-3 parts of polyvinyl alcohol, 0.8-1.8 parts of dicumyl peroxide, 2-5 parts of methacrylic resin, 2-4 parts of beta-damascone, 2-5 parts of a flame retardant and 1.4-2.2 parts of a foamer. The wood plastic material has excellent corrosion resistance, ultraviolet resistance and mechanical impact resistance by takingthe coffee shell powder as the raw material matched with other raw materials, is wide in nutritional range, wide in source of raw materials, reduces the production cost of the wood plastic material and meanwhile, solves the problem of reutilization of the coffee shells, and is green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of novel environment-friendly materials, in particular to a novel environment-friendly wood-plastic material and a preparation method thereof. Background technique [0002] Coffee is one of the most popular beverages nowadays, so coffee trees are widely planted all over the world. According to statistics, in 2016, the total output of coffee in my country's Yunnan Province alone reached 140,000 tons. During the initial processing of coffee, a large number of processing residues will be produced, such as peels, pectin, bean shells and waste water; coffee bean shells, coffee beans As a kind of waste in the production process, if the shell is not treated scientifically and effectively, it will not only cause waste of resources, but also bring serious pollution to the environment. Therefore, in order to better solve this problem, more and more scientific researchers are keen to study the potential use of coffee shells in r...
