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...
