Abstract

The invention relates to the technical field of degradable plastic, in particular to easy-to-degrade plastic which comprises, by weight, 35-45 parts of waste plastic, 10-16 parts of lignocellulose, 0.2-0.4 part of cellulose degrading enzyme, 55-65 parts of modified starch, 8-12 parts of honeycomb, 5-9 parts of antioxidant and 75-85 parts of water. A preparation method of the easy-to-degrade plastic includes following steps: (1), pretreating raw materials; (2), mixing and stirring; (3), granulating. The easy-to-degrade plastic is high in degrading rate and simple in production process, and environment pollution caused by the waste plastic is reduced.

Description

technical field [0001] The invention relates to the technical field of degradable plastics, in particular to an easily degradable plastic and a preparation method thereof. Background technique [0002] Plastic is a common and durable material, but the pollution caused by plastic is also terrible. White pollution has caused irreversible damage to the environment. Therefore, degradable plastic products have always been a hot spot in research and development. [0003] The invention utilizes waste plastics to produce degradable plastics, turning waste into treasure, not only realizes the reuse of waste plastics, but also the regenerated plastics are degradable, reducing the pollution caused by plastic products to the environment from these two sources. It protects the environment to a great extent and is a road of sustainable development. The market value is extremely high. Contents of the invention [0004] In view of the above problems, it is necessary to provide an easily...
