An environmentally friendly hydroxybutyric acid valeric acid copolyester plastic material

Abstract

The invention discloses an environment-friendly polyhydroxybutyrate-hydroxyvalerate plastic material. The environment-friendly polyhydroxybutyrate-hydroxyvalerate plastic material is composed of raw materials including, by weight part, 20-30 parts of corn starch, 10-13 parts of polyvinyl alcohol solution, 1-1.5 parts of glyoxal water solution, 7-10 parts of cashew phenolic resin, 22-24 parts of polyhydroxybutyrate-hydroxyvalerate, 8-10 parts of cellulose nanocrystal, 1.5-2 parts of silane coupling agent, 1.5-2.5 parts of dehydroacetic acid, 1.8-2.3 parts of ethyl p-hydroxybenzoate, 2-2.5 parts of di-2-ethylhexyl phthalate, 1-1.5 parts of urea, 1.8-2.5 parts of zinc stearate, 6-7 parts of epoxidized soybean oil, 8-10 parts of silk fiber, 8-10 parts of starch acetate, 15-18 parts of hard argil, 15-20 parts of talcum powder, 8-12 parts of kaolin, 8-10 parts of sepiolite, 1.5-2.5 parts of tert-butylhydroquinone, 1-1.4 parts of 2,6-di-tert-butyl-4-methylphenol, 15-18 parts of isopropanol and 16-20 parts of water.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an environment-friendly hydroxybutyrate valeric acid copolyester plastic material. Background technique [0002] A large number of discarded plastic products can be seen everywhere in various public places. They come from nature and are manufactured by humans. When they are finally attributed to nature, they are not easily absorbed by nature, thus affecting the ecological environment of nature. With the improvement of people's quality, the use of plastic products is increasing day by day, which has brought serious environmental pollution to people's lives. Now we are looking for a degradable plastic that can be completely decomposed into small molecular substances within a certain period of time. It can be recycled again, and its mechanical and optical properties are similar to those of existing plastic materials, but the current biodegradable plastics have poor water resistance...

With the improvement of people's quality, the use of plastic products is increasing day by day, which has brought serious environmental pollution to people's lives. Now we are looking for a degradable plastic that can be completely decomposed into small molecular substances within a certain period of time. Recycling, and the mechanical and optical properties are similar to existing plastic materials, but the current biodegradable plastics have poor water resistance, mechanical properties, and aging resistance
