Abstract

The invention discloses a novel plastic, which comprises the following raw materials: a polylactic acid resin, modified poly-beta-hydroxybutyric acid PHB, diisononyl phthalate DINP, octadecyl acrylate, mung bean protein powder, oxidation sweet potato starch, basic white clay, calcium carbonate, bamboo fiber, linear low density polyethylene grafted maleic anhydride, gamma-glycidyl ether oxypropyl trimethoxysilane, a methyl methacrylate-butadiene-styrene copolymer, potassium aluminum sulfate, citrate, an ethylene-vinyl acetate copolymer, N,N'-ethylenebisoleamide, diphenyl methane diisocyanate, an antifungal antimicrobial agent, a degradation agent, an antioxidant and a stabilizer. The novel plastic of the present invention has advantages of good tensile strength, good elongation at break, good impact resistance, low water absorption, and good light transmittance, can be completely degraded into carbon dioxide and water after 133-137 days, and cannot cause harm on the environment.

Description

【Technical field】 [0001] The invention belongs to the fields of plastic preparation technology and environmental protection, and in particular relates to a novel plastic. 【Background technique】 [0002] Plastics are widely used, such as plastic toys, plastic bottles, plastic packaging, plastic bags, etc. We cannot live without plastics. Studies have found that plastic products produced from polylactic acid resin can be completely degraded into carbon dioxide and water in a composting environment. Moreover, polylactic acid resin has good compatibility, transparency, solvent resistance and biaxial stretching properties, etc., and can be processed in a variety of ways. At present, the more common plastic products at home and abroad are disposable cups, knives and forks, plates, Plastic bags, non-woven fabrics, etc., theoretically as long as they are plastic products, can be made of this bioplastic material. [0003] However, as we all know, ordinary PP / PE plastics are difficu...
