Degradable environment-friendly plastic

Abstract

The invention discloses degradable environment-friendly plastic which comprises polylactic acid, polycaprolactone, a stabilizer, an antioxidant, short asbestos fibers, a bulking agent and a coupler. The formula of the degradable environment-friendly plastic comprises the following components in percentage by weight: 34-37% of polylactic acid, 15-17% of polycaprolactone, 2-4% of the stabilizer, 1.5-2.5% of the antioxidant, 23-28% of the short asbestos fibers, 4-6% of the bulking agent, 2-5% of the coupler and 0.5-3.5% of the balance of impurities. According to the plastic disclosed by the invention, polylactic acid and polycaprolactone with high environmental protection degree are polymerized and used, so that the plastic has higher stability, good heat resistance, strong toughness and good degradability, and the production cost is lowered by the formula and the plastic is applicable to wide popularization and use.

Description

technical field [0001] The invention relates to the field of plastic processing and manufacturing, in particular to a degradable environmentally friendly plastic. Background technique [0002] The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a high polymer that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few additives, such as plexiglass, polystyrene, etc. The so-called plastic is actually a kind of synthetic resin, which is similar in shape to pine resin in natural resins, but it is called plastic because it is artificially synthesized by chemical means. Studies have found that plastic product...

Problems solved by technology

Studies have found that plastic products produced by polylactic acid resin can be degraded into carbon dioxide and water in the soil. At present, common plastic products at home and abroad are not as good as disposable cups, knives and forks, plates, and plastic bags. In theory, they can be produced with bioplastic materials. , but due to its high production cost and certain defects in performance, it has not met people's requirements and has not been widely used.
