Problems solved by technology

Due to the inclusion of polyolefin substances, which cannot be completely degraded, coupled with mechanical equipment and production technology problems, its price is higher than that of the original petrochemical plastics, and the current development prospects are not optimistic.
[0008] For this reason, people can improve the performance of resin to a certain extent by adding polylactic acid and polyadipate / butylene terephthalate etc. in starch, but, the biodegradable blown film resin of prior art Mechanical properties such as tensile properties, tear strength, and elongation at break cannot meet the requirements, and the cost is relatively high

Abstract

The invention belongs to the technical field of film blowing resin and particularly relates to ethanolamine activated Na-montmorillonite and polymer composite biodegradable film blowing resin. The resin is prepared from, by weight, 50-80 parts of polyester polymer, 20-50 parts of plant starch, 5-8 parts of ethanolamine activated Na-montmorillonite, 0.5-1 part of a grafting auxiliary, 0.5-1 part of maltitol, 10-25 parts of a reactive assistant and 1-5 parts of a functional assistant. According to the resin, plant starch serves as a raw material and is subjected to gelatinization and starch compound plastification modification, the composite materials are mixed through ethanolamine activated Na-montmorillonite, the lamellar structure of modified montmorillonite is evenly dispersed in the mixture so that the molecular structure of the mixture can be more stable, then the grafting auxiliary is added for grafting of starch and copolymerization of starch and polymer, the molecular structure of starch and polyester in the composite materials is changed, and accordingly the aims of improving tensile strength and tear strength of the composite material, increasing the breaking elongation of the composite material, reducing cost and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of blown film resins, and in particular relates to an ethanolamine-activated sodium-based montmorillonite / polymer composite biodegradable blown film resin and a preparation method thereof. Background technique [0002] As we all know, white pollution is constantly destroying the environment on which we live. The whole world is trying to find a way to eliminate the harm caused by "white pollution". [0003] For this reason, biodegradable blown film resin should be conceived. Biodegradable blown film resin refers to a class of resins that are degraded by the action of microorganisms such as bacteria, mold (fungi) and algae that exist in nature. The ideal biodegradable blown film resin is a polymer material with excellent performance, which can be completely decomposed by environmental microorganisms after being discarded, and finally inorganicized to become an integral part of the carbon cycle in nature.
