Waterproof anti-aging polyethylene plastic

Abstract

The invention discloses a waterproof anti-aging polyethylene plastic which is prepared from the following raw materials in parts by weight: 20-50 parts of polycarbonate, 15-35 parts of polyethylene terephthalate, 10-20 parts of polyethylene, 1-3 parts of n-butyl 4,4-bis-(tert-butyl-peroxy)valerate, 0.5-1 part of 4,4'-diamidodicyclohexyl methane, 1-2 parts of potassium dichromate, 2-6 parts of composite carbon, 0.5-1.5 parts of silane coupling agent, 10-18 parts of zinc borate, 2-8 parts of ground calcium carbonate, 1-5 parts of muscovite, 1-6 parts of calcium silicate hydrate, 1-5 parts of meerschaum, 1-4 parts of aluminum tripolyphosphate, 0.5-1.5 parts of molybdenum disulfide, 1-3 parts of trimethyl phosphate, 0.1-0.6 part of rare earth compound, 1-2 parts of ethylene glycol monobutyl ether, 1-2 parts of lubricant, 1-3 parts of antioxidant and 1-3 parts of light stabilizer.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a waterproof and aging-resistant polyethylene plastic. Background technique [0002] With the rapid development of society and the continuous improvement of living standards, plastic products have become an indispensable position in both industrial production and people's daily life. A kind of plastic currently on the market will volatilize carcinogens in a high-temperature environment, especially food packaging plastic products commonly used in people's lives, long-term use will cause harm to human health. Polyethylene is odorless, non-toxic, has excellent high temperature resistance, and is resistant to acid and alkali erosion, but its waterproof and aging resistance are poor, and its tensile strength and impact resistance cannot meet the needs, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background t...

Problems solved by technology

At present, a kind of plastic on the market will volatilize carcinogens in a high temperature environment, especially the food packaging plastic products commonly used in people's lives. Long-term use will cause harm to human health.

Polyethylene is odorless, non-toxic, has excellent high temperature resistance, and can withstand acid and alkali erosion, but it is poor in waterproof and aging resistance, and its tensile strength and impact resistance cannot meet the needs, so it needs to be solved urgently
