Abstract

The invention discloses environment-friendly plastic. The plastic is prepared from the following raw materials: polylactic resin, modified poly-beta-hydroxybutyric acid PHB, diisononyl phthalate DINP, epoxy tall oil butyl acetate, peanut protein flour, oxidized corn starch, alkaline clay, calcium carbonate, jute fibers, linear low-density polyethylene grafted maleic anhydride, gamma- glycidoxy propyl trimethoxy silane, methyl methacrylate-butadiene-styrene copolymer, aluminum potassium sulfate, citrate, ethylene-vinyl acetate copolymer, ethylene bis-oleamide, diphenyl-methane-diisocyanate, an antimycotic antibacterial agent, a degradation agent, antioxidant and a stabilizing agent. The environment-friendly plastic has good tensile strength and elongation at break, has good impact resistance, relatively low moisture absorption and good light transmittance, and can be completely degraded into carbon dioxide and water in 132-135 days, and has no pollution to the environment.

Description

[0001] 【Technical field】 [0002] The invention belongs to the fields of plastic preparation technology and environmental protection, and in particular relates to an environmentally friendly plastic. [0003] 【Background technique】 [0004] 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. [0005] However, as we all know, ...
