Abstract

The invention discloses environment-friendly and biodegradable type plastics. The environment-friendly and biodegradable type plastics comprises polylactic resin, modified polyvinyl-beta-hydroxybutyric acid PH B, diisononyl phthalate (DINP), tung oil based alkyd resin, soybean protein powder, oxidized cassava starch, alkaline clay, calcium carbonate, kapok fiber, linear low-density polyethylene grafted maleic anhydride, gamma-propyl glycidyl ether oxygen based trimethoxy silane, methyl methacrylate-butadiene-styrol copolymer, aluminum potassium sulfate, citrate, ethylene-eva ethylene, ethylene bis oleamide, methylene diphenyl diisocyanate, an antimycotic antibacterial agent, a degradation agent, antioxidant and a stabilizer. The plastics is good in tensile strength and breaking elongation, good in impact resistance, low in water absorption and good in light-transmitting quality, can be completely degraded into carbon dioxide and water after 132-136 days, and harm cannot be caused 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 and degradable 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, a...
