Problems solved by technology

Halogen-containing cable materials are widely used in the field of power cables due to their excellent insulation and flame retardancy, which solves the problem of poor flame retardancy of traditional cable materials
However, the halogen-containing cable material will produce a lot of smoke when it is burned. Inhaling a large amount of this smoke can cause people to suffocate. Therefore, when a fire occurs, the halogen-containing cable material will increase th...

Description

Technical field [0001] The invention relates to the technical field of cable materials, in particular to a radiation-resistant halogen-free flame-retardant ethylene-propylene cable material and a preparation method thereof. Background technique [0002] The cable is mainly composed of a cable core, an insulation layer and a sheath. The main purpose of the insulation layer and the sheath is to protect the cable core in the cable to ensure normal transmission. The insulation layer and sheath of the cable are collectively referred to as the cable material, so the performance of the cable material directly affects the quality of the cable. Cable materials containing halogen are widely used in the field of power cables because of their excellent insulation and flame retardancy, which solves the problem of poor flame retardancy of traditional cable materials. However, the halogen-containing cable material will produce a lot of smoke when it is burned. A large amount of this smoke can ...
