Fully bio-degradable plastic master batch and preparing process thereof

Abstract

The invention provides a complete biodegradable plastic masterbatch and method for making same, wherein the plastic masterbatch comprises starch, coupling agent, dispersing agent, poly cyclic lactone, plasticity agent, and oxidation agent, while the preparation process comprises the steps of, (1) fining of starch, dewatering, (2) mixed melting, (3) extrusion forming.

Description

Technical field

[0001] The invention relates to a biodegradable plastic master batch and a preparation method thereof, in particular to a completely biodegradable plastic master batch and a preparation method thereof. Background technique

[0002] Various degradable plastic materials are known on the market, such as: photodegradation, photobiodegradation, photooxidation biodegradation, high starch content biodegradation, high calcium carbonate photooxidation degradation plastic materials, etc. However, because these plastic materials contain more or less polyolefin components such as polyethylene, polypropylene, polystyrene or polyvinyl chloride, the degradation is not complete after being discarded, and the problem of "white pollution" has not been completely solved.

[0003] In recent years, "Introduction to the characteristics of polycaprolactone and its application prospects" (Chinese Academy of Sciences Xinjiang Branch, Academic Report of the Fourth Xinjiang Academic Annual ...
