Problems solved by technology

These waste plastic packages are scattered in urban areas, scenic tourist areas, water bodies, and both sides of roads, which not only affect the landscape and cause "visual pollution", but also cause potential harm to the ecological environment because they are difficult to degrade
[0004] At present, although there are many studies and reports on degradable plastics, their degradation effects are not satisfactory. Therefore, it is necessary to improve the existing technology and develop new types of degradable plastics.

Abstract

The invention belongs to the field of plastics, and particularly relates to an easy-to-degrade modified plastic particle. The plastic particle is characterized by comprising the following components in parts by mass: 20-30 parts of polyethylene, 10-16 parts of lignocellulose, 30-40 parts of modified starch, 10-20 parts of dried coconut shell powder, 1-10 parts of ramie fiber, 0.1-0.5 part of cellulose degrading enzyme, 0.1-0.5 part of amylase, 10-15 parts of a pigment and filler, 1-5 parts of a coupling agent, 1-5 parts of a dispersant, 1-5 parts of a stabilizer, 1-5 parts of a plasticizer, and 1-5 parts of an antioxidant. The plastic particle prepared by the formula has a degradation rate of 97% or more, and the degradation effect is very good.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to an easily degradable modified plastic particle. Background technique [0002] As a new type of material, plastic products have the advantages of light weight, waterproof, durable, mature production technology, and low cost. They are widely used all over the world and show a growing trend year by year. The growth rate of plastic packaging materials in the world market is higher than that of other packaging materials. From 1990 to 1995, the average annual growth rate of plastic packaging materials was 8.9%. [0003] my country is one of the top ten plastic products producing and consuming countries in the world. In 1995, my country's plastic output was 5.19 million tons, and imported plastics were nearly 6 million tons. The total national plastic consumption in that year was about 11 million tons, of which packaging plastics reached 2.11 million tons. Most of the packaging plastic is disc...
