Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an aging-resistant and low-temperature resistant EPDM cable material. Background technique [0002] EPDM rubber is a polymer composed of propylene, ethylene and conjugated diene. Since the carbon atoms on the main chain are in a saturated structure, and only a few unsaturated carbon atoms are on the side chains, it has many excellent processing properties. Performance and use performance, such as low density, weather resistance, heat resistance and ozone resistance, excellent mechanical properties, etc. With the rapid development of the world industry, the quantity, especially the quality, of EPDM is getting higher and higher. The strength, aging resistance and flame retardancy of the existing EPDM materials are not very ideal. Modification of EPDM rubber to meet the actual technical requirements of modern society is a hot issue in current research. Contents of the inv...
