Abstract

The invention discloses an anti-aging antibacterial PE (Poly Ethylene) film and a preparation method thereof. The film contains the following raw components in parts by weight: 100 parts of PE resin,15-30 parts of polyvinyl alcohol, 3-5 parts of shell powder, 5-10 parts of nano calcium carbonate, 1-3 parts of silicon nitride fiber, 0.5-1.5 parts of phytic acid, 1-2 parts of octaphenyl cage-type silsesquioxane, 0.5-1.5 parts of polyaminopropyl methyl silsesquioxane, 1-5 parts of carboxymethyl cellulose, 2-4 parts of processing aid, 0.5-1.5 parts of composite antibacterial agent and 0.5-2 partsof antioxidant. The compatibility of the components is good due to the coordination effect of the components; and the prepared PE film has the advantages of high strength, heat resistance, high temperature resistance, good stability, aging resistance, strong antibacterial effect, aging resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to an aging-resistant and antibacterial PE film and a preparation method thereof. Background technique [0002] Polyethylene (PE for short) is a thermoplastic resin obtained by polymerizing ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 ° C ~ -70 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation) nature of the acid). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation, so it is widely used in various industries. Polyethylene film is the most widely used polymer material in the world today, and has been widely used in medicine, chemical industry, Food, electro...
