Degradable mother particles of plastics for protecting environment

Abstract

A degradable mother material of plastics is prepared from white sludge generated by making paper or refining sugar, polyslefin, optical trigger, bioactivity decreaser, assistant, and coupling agent. Its advantages are low cost and no environmental pollution.

Description

technical field [0001] The invention relates to a masterbatch of degradable plastics, in particular to a masterbatch for making degradable plastics. Background technique [0002] Plastic is the most widely used material after wood, steel, and cement, ranking first in the world in terms of volume. In 1998, the world's plastic output was about 150 million tons. However, the huge and difficult-to-degrade "white pollution" seriously pollutes the environment. In addition, the raw material for the production of plastics is non-renewable petroleum resources, and the reserves of petroleum have become less and less. According to reports, the world's petroleum production can only be used for forty years. Therefore, it is imminent to find new environmentally friendly materials that can replace petroleum resources. While improving people's environmental awareness, it is an important condition and effective means to implement resource saving (reduction), r...

Problems solved by technology

But this inorganic base material composite degradable plastics has following shortcoming simultaneously; (1) biodegradation mainly relies on the reaction product of Norrysh reaction The hydroxyl group in is corroded by microorganisms, and the reaction formula is as follows After measuring the quantum yield of I and II reactions, the results show that both products may be obtained, but the quantum yield of reaction I is only 1 / 100 of that of reaction II at room temperature, so the possibility of biodegradation is small

(2) No biologically active reducing agent, can not accelerate the degradation of residual film
