Abstract

The invention discloses an anti-aging plastic product containing polyethylene wax. The anti-aging plastic product is prepared from the following raw material in parts by weight: 60 to 80 parts of main material, 2 to 8 parts of silane coupling agent KH-550, 4 to 8 parts of modified polyethylene wax, 40 to 50 parts of filling material, 2 to 4 parts of dicumyl peroxide, 1 to 2 parts of diphenylamine, 1 to 2 parts of polycaprolactone, 1 to 2 parts of phenol formaldehyde resin and 1 to 2 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The modified polyethylene wax is prepared by the following steps: adding polyethylene wax into a citric acid sodium solution; heating and stirring; adding agarose; performing ultrasonic treatment; performing microwave treatment; adding a product into liquid paraffin; stirring in an ice water bath to obtain modified polyethylene wax.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an aging-resistant plastic product containing polyethylene wax. Background technique [0002] Plastics are widely used, and plastic products are inseparable from various fields and people's daily life. At present, the total amount of plastic products in the world has already exceeded 100 million tons. Polyethylene wax is a commonly used additive in the plastic processing industry. It has a high softening point, but low melt viscosity, good dispersion and fluidity, and has good compatibility with other waxes and polyolefin resins. High moisture resistance, chemical resistance and excellent properties. But at present, the polyethylene wax added in polypropylene plastic is easy to overflow, and the plastic product is easy to age under long-term use, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems in the background technology...
