Problems solved by technology

But like most hydrocarbon polymers, EPDM rubber is also very flammable, and the oxygen index of pure rubber is only about 19. In addition, the current cables generally have poor cold resistance and are prone to embrittlement.

Abstract

The invention discloses a high cold-resistance ethylene propylene diene copolymer insulated cable material and a preparation method thereof. The cable material is made of the following raw materials in parts by weight: 100-120 parts of Lanxess Deutschland 9650 ethylene propylene diene copolymer, 20-30 parts of active chlorine type acrylic rubber AR-400, 10-15 parts of duprene rubber CR121, 10-15 parts of di-butyl nylonic acid ester, 5-10 parts of trioctyl trimellitate, 5-10 parts of triethyl phosphate, 1-2 parts of sulphur, 2-4 parts of benzoyl peroxide, 1-2 parts of triallyl isocyanurate and the like. The cable material not only has excellent flame retardance and incombustibility, but also has the advantages of good high and low temperature resistance, corrosion resistance, water resistance, wear resistance, ozone resistance, ageing resistance and the like at the same time, and is durable in use.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a high cold-resistant EPDM insulating cable material and a preparation method thereof. Background technique [0002] Since the advent of EPDM in 1962, due to its excellent ozone resistance, weather aging resistance and heat aging resistance, as well as good electrical insulation, heat deformation resistance and chemical corrosion resistance, the relative density It is small and has a large filling volume, which is valued by the cable industry. At present, it has replaced traditional styrene-butadiene, natural, and butyl rubber, and is widely used in medium and high voltage cables for ships and mobiles. But like most hydrocarbon polymers, EPDM rubber is also very flammable, and the oxygen index of pure rubber is only about 19. In addition, cables generally have poor cold resistance and are prone to embrittlement. Therefore, the development of high cold-resistant and flame-retardan...
