Abstract

The invention discloses an environmental protection plastic, which comprises, by mass percentage, 20-30% of polylactic acids, 25-40% of polycaprolactone, 25-40% of short asbestos fibers, 5-12% of compatibilizers and 2-8% of coupling agents. According to the environmental protection plastic, the polylactic acids and the polycaprolactone which are environment-friendly and degradable are used to be polymerized, a plurality of auxiliaries are added, intensity, toughness and heat-resistant performance are improved, the production cost is lowered, general-purpose plastics can be replaced, and the environmental protection plastic can be applied to the field of engineering plastics.

Description

technical field [0001] The invention relates to the field of plastic materials, in particular to an environment-friendly plastic. Background technique [0002] As we all know, ordinary PP / PE plastics are difficult to decompose in the natural environment for hundreds of years. Therefore, plastic waste is recognized as an artificially produced substance that pollutes the environment. However, plastics are widely used, such as plastic toys, plastic bottles, plastic packaging, plastic bags, etc. We cannot live without plastics. [0003] 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, ...
