Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a high-performance modified fluorine rubber cable sheath material. Background technique [0002] Fluorine rubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. It has good chemical stability, excellent high temperature resistance, good aging resistance and excellent mechanical properties. It is a modern aviation, missile, rocket, Indispensable materials for cutting-edge science and technology such as space navigation. With the development of electric power, the usage of fluorine rubber in power cables is also increasing rapidly. However, the elasticity of fluorine rubber is poor, and the existing fluorine rubber used as cable sheath material often cannot meet the needs of society in terms of hardness, compressive strength, and tensile strength under the condition of maintaining elasticity, and...
