Description

Technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a cold- and oil-resistant 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 used in modern aviation, missiles, rockets, Indispensable materials for cutting-edge science and technology such as astronautics. With the development of electric power, the amount of fluorine rubber in power cables has also increased rapidly. However, fluorine rubber has poor cold resistance, and pure fluorine rubber used as a cable sheath material cannot meet the needs of society. Summary of the invention [0003] The present invention proposes a cold and oil resistant modified fluorine rubber cabl...
