Degradable plastic and method for preparing same

Abstract

The invention discloses a degradable plastic. The degradable plastic is made of, by weight, 60-65 parts of starch, 50-55 parts of polycaprolactone, 70-75 parts of poly butylenes succinate, 75-80 parts of polyhydroxyalkanoate, 20-30 parts of polyvinyl alcohol, 4-6 parts of chitin, 7-15 parts of polyaspartate acid, 15-20 parts of celluloses, 10-15 parts of polypropylene, 13-16 parts of phenolic resin, 2-4 parts of diatomaceous earth, 20-30 parts of asbestos, 15-20 parts of carbon black, 8-10 parts of phthalate, 35-40 parts of silicone rubber, 12-14 parts of diisononyl phthalate, 5-8 parts of zinc chromate and 12-16 parts of organic tin. The degradable plastic has the advantages that the degradable plastic is good in thermoplastic property and can be sufficiently degraded, and good anti-aging effects can be realized.

Description

technical field [0001] The invention relates to a degradable plastic and a preparation method thereof. Background technique [0002] Degradable plastics refer to plastics that add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) [0003] Photodegradable plastics are mixed with photosensitizers in plastics, and the plastics are gradually decomposed under sunlight. It belongs to an earlier generation of degradable plastics, and its disadvantage is that the degradation time is difficult to predict due to sunlight and climate changes, so the degradation time cannot be controlled. [0004] Biodegradable plastics can be completely decomposed into plastics of low molecular weight compounds under the action of microorganisms. It is characterized by convenient storage and transportation, as long as it is kept dry, it does not need to be protected from light, and has a wide range of applications. It can be used...
