Abstract

The invention discloses a transparent multifactor degradation modified polyethylene film and a preparation method thereof, and belongs to the technical field of preparation of new polymer materials. The formula contains polyethylene, sulfonated polyetheretherketone, zinc phenyl phosphate, a maleic anhydride grafted ethylene-octene copolymer (POE-g-MAH), a polyvinyl alcohol-polymethyl methacrylatecopolymer, a microbial nutrient additive, polyethylene glycol (PEG 400), sorbeth, manganese stearate, a methyl vinyl ether maleic anhydride copolymer, chitosan oligosaccharide, lactide, an epoxy silane coupling agent, fine pyrophyllite powder, bis(3,4-dimethyl benzylidene) sorbitol and glycerin. With the adoption of technological means of cold grinding modification and further modification by fusion, the transparent multifactor degradation modified polyethylene film is prepared with high efficiency and low energy consumption. The production technology is simple and clean and is suitable for industrial production.

Description

technical field [0001] The invention relates to a transparent multi-factor degradable modified polyethylene film and a preparation method thereof, belonging to the technical field of preparation of new polymer materials. Background technique [0002] Plastic products with excellent performance and low price have entered all aspects of production and life. With the continuous expansion of their uses and increasing consumption, the environmental problems caused by plastic products have become more and more serious, and have attracted the attention of countries all over the world. Among them, polyolefin is used in a huge amount due to its low cost and excellent processing performance, but the molecular structure of polyethylene does not have degradable functional groups, so it can degrade for hundreds of years under natural conditions. [0003] The factors affecting the degradation performance of polymer materials mainly include the following aspects: the polymer structure must...
