Problems solved by technology

However, as a polymer synthetic material, fluororubber will age due to the joint action of heat, oxygen, force, medium and other factors in the working environment during use and storage, and its performance will gradually decline over time. In addition, the low temperature resistance of fluorine rubber is poor, and the current fluorine rubber is used as a cable sheath material, and its aging resistance and low temperature resistance cannot meet the requirements of the society.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a low-temperature and aging-resistant modified fluororubber cable sheath material. Background technique [0002] Fluorine rubber is a polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. Compared with other rubber materials, the most significant advantage of fluorine rubber is that it has the characteristics of high temperature resistance, oil resistance and corrosion resistance of various chemicals. , so it is widely used in various fields. However, as a polymer synthetic material, fluororubber will age due to the joint action of heat, oxygen, force, medium and other factors in the working environment during use and storage, and its performance will gradually decline over time. Even loss of performance, in addition, the low temperature resistance of fluorine rubber is poor, and the current fluorine rubber as a cable she...
