Abstract

The invention discloses an oil resistant, high and low temperature resistant ethylene propylene diene monomer / polyurethane rubber bable material. The raw material comprises the following components: ethylene propylene diene monomer rubber, polyurethane rubber, ethylene acrylate, EPDM rubber grafted with maleic anhydride, carbon black, pottery clay, coumarone resin, zinc oxide, stearate, magnesia, zinc methacrylate, benzoyl peroxide, trimerization thiocyanate, trimethylol propane trimethacrylate, accelerator M, accelerant DZ, antioxidant, dihydroxy higher alcohol, diethylene glycol dibenzoate, epoxidized soybean oil and N-(morpholine thiosulfate) phthalimide. The oil resistant, high and low temperature resistant ethylene propylene diene monomer / polyurethane rubber bable material disclosed by the invention is high in mechanical strength, excellent in oil resistance, high in temperature resistance and cold tolerance; and the cable made from the material is long in service life, so that the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an oil-resistant, high-low temperature resistant EPDM / polyurethane rubber cable material. Background technique [0002] EPDM rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and excellent processing properties, and is widely used in the cable industry. 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 night is large, and cable materials are required to have high and low temperature resistance. The high and low temperature resistance and oil resistance of the existing EPDM cable materials cannot meet the requirement...
