Waterproof polyethylene cable material excellent in mechanical property

Abstract

The invention discloses a waterproof polyethylene cable material excellent in mechanical property. The material is prepared from, by weight, 30-50 parts of polyethylene, 15-25 parts of polystyrene, 8-16 parts of low-density polypropylene, 0.5-1.2 parts of aluminic acid ester coupling agent, 1-2 parts of maleic anhydride grafted polypropylene, 0.5-1.2 parts of trimethylolethane, 2-8 parts of modified activated zeolite powder, 2-4 parts of zinc sulfide, 2-6 parts of ceramic microspheres, 1-3 parts of boric oxide, 1-3 parts of antimony trioxide, 4-8 parts of ethylene propylene terpolymer, 2-4 parts of glycollic amide, 2-3 parts of cyclohexanone peroxide, 1-2 parts of ammonium pyrophosphate, 1-2 parts of silicone batch, 0.5-1.5 parts of dimethyl phthalate, 0.5-1.5 parts of pentaerythritol, 0.5-1.5 parts of diphenylamine and 1-2 parts of di-iso-decylphthalate. The material is excellent in mechanical property, not easy to tear and good in waterproof prevention and acidic salt and alkaline salt resistance.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a waterproof polyethylene cable material with excellent mechanical properties. Background technique [0002] Plastic is a synthetic polymer compound. Most plastics have the advantages of light weight, stable chemical properties, no rust, good impact resistance, and good insulation. Therefore, plastics are widely used in the field of cable materials. Polyethylene plastic has good electrical, mechanical, low-temperature resistance, and high cost performance, but polyethylene has poor mechanical properties, poor acid, alkali and salt resistance, and waterproof performance cannot meet the needs, which limits its application range in the field of cable materials. waiting to be solved. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a waterproof polyethylene cable material with excellent mechanical prop...
