Problems solved by technology

[0002] In recent years, with the rapid development of China's economy, the contradiction of tight energy supply has become more and more prominent. In order to meet this demand, major coal mines have adopted high-power coal mining equipment to increase production capacity, and the supporting cables for power transmission The requirements are constantly improving. Ethylene-propylene rubber insulation has high operational reliability and other advantages. The amount of ethylene-propylene rubber in cable production is also increasing. The existing ethylene-propylene rubber materials are increasingly unable to meet the rapid development of social needs. How to prepare a kind of mining rubber material with excellent flame retardancy and waterproof, good mechanical properties and good economic benefits has become a technical problem that needs to be solved at present
