Abstract

The invention discloses a high-barrier PE material. The high-barrier PE material comprises, by weight, 60-80 parts of polyethylene, 5-10 parts of hydroxyethyl acrylate, 1-5 parts of triphenyl phosphite, 10-20 parts of a polymer / nano-SiO2 composite material and 2-6 parts of a flame retardant. The PE is modified with the polymer / nano-SiO2 composite material, so the barrier property of the PE material is improved.

Description

technical field [0001] The invention relates to a PE material and a preparation process, in particular to a high-barrier PE material and a preparation process thereof. Background technique [0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene resin has a wide range of sources, low price, good electrical and processability, and is widely used in daily necessities, outer packaging, automobile body, construction industry and household electrical appliances. Polyethylene has no irritating smell, almost no toxicity, and has good Excellent low temperature resistance, excellent chemical stability, resistance to most acids and alkalis, insoluble in general solvents at room temperature, low hygroscopicity, good electrical insulation performance, etc. [0003] At present, polyethylene is used in part of the outer packaging. Due to the poor barrier property of polyethylene, some packaged products (food, medicine, cosmetics, etc.) are ...
