Problems solved by technology

[0002] Wires and cables have become an indispensable product in people's lives. They have different requirements in different occasions. At present, the main formulas of rubber are as follows: natural styrene-butadiene rubber, EPDM rubber, chlorinated polyethylene, Or chlorosulfonated polyethylene, among which, chlorinated polyethylene rubber is the most commonly used. This type of rubber is made of chlorinated polyethylene rubber as the main material, and other compounding agents are added through steam cross-linking reaction, but steam cross-linking must pass Combustion of coal or oil boilers produces steam, which is a high energy-consuming process and cannot meet the standard requirements
If the existing chlorinated polyethylene rubber formula is prepared by irradiation crosslinking, the obtained rubber cannot meet the standard requirements for rubber materials for wire and cable
