Problems solved by technology

[0002] The known degradable plastic materials contain polyolefins such as polyethylene and polypropylene, so they are not completely degraded after being discarded, and the problem of "white pollution" has not been completely solved. A large amount of plastic waste in life has caused great pressure on the environment
However, although some high polymers such as polyethylene are substances with high biological components, they cannot be biodegraded. How to make high polymers with both biodegradable and high biochar content is the technical problem to be solved in this application.

Abstract

The invention relates to a master batch high in charcoal content and a processing technology of the master batch, and belongs to the technical field of compositions of macromolecular compounds. The master batch is prepared from, by mass, 35-50% of starch, 30-40% of biological polyethylene, 1.8-8% of coupling reagent, 7-20% of biological plasticizer (epoxidized fatty acid methyl ester, namely, an epoxy plasticizer processed by waste oils and fats, namely, acidified soybean oil, and the balance lubricating agent, antioxidant and degradant additive. When used for processing plastic bags and other biodegradable plastics, the master batch has the advantages of being high in charcoal content, good in biodegradablity and the like.

Description

technical field [0001] The invention relates to a high biochar content master batch and a processing technology thereof, belonging to the technical field of polymer compound compositions. Background technique [0002] The known degradable plastic materials contain polyethylene, polypropylene and other polyolefin components, so that the degradation is not complete after disposal, and the problem of "white pollution" has not been completely solved. The large amount of plastic waste in life has caused great pressure on the environment. . While some high polymers such as polyethylene are high biological components, they cannot achieve biodegradation. How to make the high polymer have both biodegradation and high biochar content is the technical problem to be solved by this application. [0003] Based on this, the present application is made. SUMMARY OF THE INVENTION [0004] Aiming at the above-mentioned defects of existing degradable plastic products, the present applicatio...
