Abstract

The invention discloses an incinerated pottery clay modified ethylene propylene diene copolymer cable material, which is prepared from the following raw materials in parts by weight: 100-120 parts of Lanxess Deutschland ethylene propylene diene copolymer 3950, 20-30 parts of nitrile butadiene rubber N41, 10-15 parts of chlorosulfonated polyethylene rubber CSM2305, 10-15 parts of diisodecyl phthalate; 2-5 parts of epoxidized triglyceride, 2-5 parts of triethyl citrate, 5-8 parts of chlorinated paraffin wax, 0.5-1.0 part of stearic acid, 2-3 parts of calcium stearate, 1-2 parts of sulphur, 3-5 parts of zinc oxide, 30-40 parts of incinerated pottery clay, 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 calcined clay-modified EPDM cable material. 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 low- and medium-voltage cables for marine and mobile use. But like most hydrocarbon polymers, EPDM rubber is also very flammable, and the oxygen index of pure rubber is only about 19. Therefore, the development and development of flame-retardant EPDM cable materials has been valued by the cable industry. Contents of the invention [0003] The purpose of the present invent...
