Acidophilic microorganism degradation plastic master batch and preparation method thereof

Abstract

The invention discloses an acidophilic microorganism degradation plastic master batch and a preparation method thereof. The acidophilic microorganism degradation plastic master batch is formed by meltpolymerization of a methyl-glycolide-lactic acid acidic monomer and an organic silicon colloid under the catalytic action of SnCl2. The acidophilic microorganism degradation plastic master batch provided by the invention has high purity and good applicability, is easily decomposed by acidophilic microorganisms, can provide survival energy for the acidophilic microorganisms, and has harmless decomposition products.

Description

technical field [0001] The invention relates to the field of environmentally friendly plastic processing, in particular to an acidophilic microorganism degradable plastic masterbatch and a manufacturing method thereof. Background technique [0002] Environmentally friendly plastic is the abbreviation of various biodegradable plastics. With the development of science and technology, various materials that can replace traditional PE plastics have emerged, including PLA, PHAs, PBA, PBS and other polymer materials. [0003] However, the degradation rate of environmentally friendly plastics in the prior art is actually relatively slow, and polymerization is relatively difficult. Strength and high temperature resistance are significantly lower than PE plastic bags. Some environmentally friendly plastics can be decomposed by microorganisms, but because they have no nutrients themselves, it is difficult for microorganisms to multiply rapidly to accelerate the decomposition process, ...

[0003] However, the degradation rate of environmentally friendly plastics in the prior art is actually relatively slow, and the polymerization is relatively difficult

Strength and high temperature resistance are significantly lower than PE plastic bags. Some environmentally friendly plastics can be decomposed by microorganisms, but because they have no nutrients themselves, it is difficult for microorganisms to multiply rapidly to accelerate the decomposition process, or the decomposed products have a relatively small molecular weight. organic matter, but its chemical properties are still extremely stable, it is still harmful to the environment and it is difficult to be digested by nature

In the prior art, there has never been a biodegradable environmentally friendly material as a masterbatch (additive or auxiliary agent in the plastics industry)
