Problems solved by technology

It belongs to an earlier generation of degradable plastics. Its disadvantage is that the degradation time is difficult to predict due to sunlight and climate changes, so the degradation time cannot be controlled; biodegradable plastics are plastics that can be completely decomposed into low-molecular compounds under the action of microorganisms, but the process It is more complicated; photo / biodegradable plastics have the advantages of both photodegradable plastics and biodegradable plastics, but the cost is relatively high; water-degradable plastics are mainly used in the medical industry, which are easy to disinfect and destroy, and have relatively limited use

Abstract

The invention provides an environmentally-friendly degradable plastic and a preparation method thereof, and relates to the technical field of plastic processing. The environmentally-friendly degradable plastic is prepared from, by weight, 40-50 parts of polylactide, 12-14 parts of polybutylene succinate, 4-8 parts of polyvinyl chloride, 4-10 parts of plant fibers, 30-40 parts of grafted starch, 1-3 parts of calcium oxide, 1-3 parts of oligosaccharides, 1-1.6 parts of nano-silica, 1-2 parts of polyaluminum chloride, 0.6-1.6 parts of sodium citrate, 0.4-0.8 part of a dispersant, 0.2-0.5 part ofa crosslinking agent and 1-1.2 parts of a plasticizer. The preparation method overcomes the deficiencies of the prior art, adopts a combination of various biodegradable components to prepare the starch blended plastic in order to make the product effectively and completely degraded, and has the advantages of simple production process, convenience in production and low cost, and is suitable for promotion and production.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to an environmentally friendly degradable plastic and a preparation method thereof. Background technique [0002] Due to its light weight, chemical stability, no rust, good impact resistance and other excellent properties, plastics have replaced most of the basic materials and become commonly used raw materials in people's lives. However, since plastics are not easy to degrade as polymer materials, they cause great harm to the environment. . Facing the increasingly serious problem of white pollution, people hope to find a plastic substitute that can replace the performance of the current plastics without causing white pollution. Degradable plastics have emerged as the times require. This new type of functional plastic is characterized by reaching a certain level After the service life is discarded, under certain environmental conditions, due to obvious changes in its che...
