Abstract

The invention relates to an environmentally-friendly modified plastic, which comprises, by mass, 25-35% of polylactic acid, 10-15% of a plasticizer, 8-15% of a lubricant, 26-40% of polycaprolactone, 28-40% of short asbestos fiber, and 3-8% of a coupling agent. According to the invention, the environmentally-friendly modified plastic is provided, wherein environmentally-friendly degradable polylactic acid and environmentally-friendly degradable polycaprolactone are polymerized, and a variety of aids are added, such that the strength, the toughness and the heat resistance of products are improved, the production cost is reduced, and the obtained product can replace general plastics, and can be used in the field of engineering plastics.

Description

technical field [0001] The invention relates to the field of plastic materials, in particular to an environmentally friendly modified 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. 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, plate...
