Abstract

The invention discloses a modified ethylene propylene diene monomer composite cable material resistant to high and low temperatures. The modified ethylene propylene diene monomer composite cable material resistant to high and low temperatures is prepared from maleic anhydride-grafted ethylene propylene diene monomer, polymethylvinylphenylsiloxane gum, an ethylene-octene copolymer, white carbon black, mica, calcined clay, hydrotalcite, stearic acid, zinc oxide, sulphur, bis(2,4-dichlorobenzoyl)peroxide, glycol, polyethylene glycol, 3-aminopropyltrimetyoxysilane, an accelerant, a plasticizer and an anti-aging agent. The modified ethylene propylene diene monomer composite cable material resistant to high and low temperatures is high in strength, excellent in anti-aging performance, and good in high-and-low temperature resistance and cold tolerance, and a cable material made of the modified ethylene propylene diene monomer composite cable material resistant to high and low temperatures is good in comprehensive performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high and low temperature resistant modified EPDM composite cable material. Background technique [0002] Since the advent of EPDM rubber, 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 is small and the filling volume is large. , by the cable industry's attention. 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. With the development of society, people have put forward higher requirements on the performance of cables. In addition, the use environment of cable materials is often complex and changeable, especially in winter in northern regions, where the temperature difference between day and n...
