Finally, epoxyphenyl silicone rubber and perfluorohexylethyl alcohol are reacted, and the epoxy groups on the epoxyphenyl silicone rubber react with the hydroxyl groups on the perfluorohexylethyl alcohol, and then a large number of CF bonds are introduced into the silicone rubber to obtain a wear-resistant modified rubber; the molecular structure of the wear-resistant modified rubber contains a large number of phenyl groups, so that the rigidity and intramolecular friction of the molecular chain are enhanced, and the large number of CF bonds introduced make the molecular chain show good lubricity, so that it has a low friction coefficient, greatly improves its wear resistance, and the polarity of the molecular chain is improved after the alkenyl groups are converted into epoxy groups. , thereby enhancing the intermolecular force and improving the air tightness and adhesion of the rubber, thereby improving the mechanical properties of the rubber, and enhancing the interaction force between the rubber and other raw materials, and enhancing the reinforcement effect; in the process of preparing the wear-resistant modified rubber cable material for new energy vehicles, a modified potassium titanate whisker is also prepared, and the potassium titanate whisker is treated with γ-glycidyloxypropyltrimethoxysilane, and the siloxane on its molecular structure is hydrolyzed by γ-glycidyloxypropyltrimethoxysilane to form silanol, which is then grafted to the surface of the potassium titanate whisker to obtain the modified potassium titanate whisker; potassium titanate whisker has good high temperature resistance, heat resistance, high strength and high modulus. Adding it to the rubber material can enhance and modify it, greatly improve its mechanical properties and wear resistance, and after modification, a large amount of organic matter is introduced to its surface for wrapping, thereby greatly improving the dispersibility of the potassium titanate whisker, so that it can be evenly compatible with the rubber material, and a large number of epoxy groups will be introduced, so that it can be chemically bonded with the rubber material, thereby further improving the comprehensive performance of the rubber material. Therefore, under the synergistic effect of wear-resistant modified rubber and modified potassium titanate whiskers, the cable material is endowed with excellent mechanical strength and wear resistance, thereby improving the reliability and safety of the cable material.
