Abstract

The invention discloses an outdoor overhead ageing-resistant insulating polyolefin cable material and a preparation method thereof. The outdoor overhead ageing-resistant insulating polyolefin cable material comprises, by weight, 60-80 parts of ethylene-vinyl acetate copolymer, 30-40 parts of chlorosulphonated polyethylene, 4-6 parts of isopropyl phenyl diphenyl phosphate, 4-5 parts of acetyl tri-n-butyl citrate, 8-10 parts of magnesium hydroxide, 40-50 parts of di-iso-decylphthalate, 6-8 parts of butadiene triethoxy silane, 2-4 parts of organic chromium complex, 6-8 parts of lead sulfate tribasic, 5-7 parts of p-phenylenediamine, 30-40 parts of nano calcium carbonate, 6-10 parts of beta-diketone, 12-14 parts of ammonium polyphosphate, 7-8 parts of silicone emulsion, 5-7 parts of fluoro-alkyl polyether modified polysiloxane, 7-9 parts of zinc stearate, 5-8 parts of nano calcium superoxide, 6-9 parts of paraffin and 8-12 parts of hexadecyl dimethyl amine. According to the outdoor overhead ageing-resistant insulating polyolefin cable material and the preparation method thereof, the added di-iso-decylphthalate plasticizer and the ethylene-vinyl acetate copolymer are matched, in this way, the aging resistance is improved, the processability is also improved, and the flexibility of a cable is improved; meanwhile, the ammonium polyphosphate has the condensation and phase neutralizing functions, and an extremely good frame retardant effect is achieved through the combination of the ammonium polyphosphate and the magnesium hydrate; the added chlorosulphonated polyethylene has the wear resistance, electric insulation resistance and other characteristics.

Description

Invention field [0001] The invention relates to a cable material, in particular to an anti-aging insulating polyolefin cable material for outdoor aerial use and a preparation method thereof. Background technique [0002] In recent years, the national rail transit has developed rapidly, the control of EMUs and high-speed units has become more and more complex, and there are more and more electrical control equipment. The demand for cables will inevitably increase, and the performance requirements for cable materials will also increase. More stringent. At present, polyolefin cable materials on the market have disadvantages such as poor mechanical properties, poor weather resistance, and poor aging resistance. They are prone to aging and cracking when exposed to the outside for a long time, which cannot meet market needs. Summary of the invention [0003] The purpose of the present invention is to provide an anti-aging insulating polyolefin cable material for outdoor overhead aerial...
