Abstract

The invention discloses a high-temperature-resistant and aging-resistant cable sheath material. The high-temperature-resistant and aging-resistant cable sheath material is prepared from, by weight, 60-80 parts of nitrile butadiene rubber, 25-35 parts of methyl vinyl silicone rubber, 3-8 parts of zinc oxide, 2-7 parts of magnesium stearate, 12-18 parts of diethylene glycol monoethyl ether acetate, 10-16 parts of 2,2,2-trichloroacetamide benzyl ester, 11-18 parts of ethopabate, 4-10 parts of acetazolamide, 3-7 parts of magnalium zirconium oxide, 4-7 parts of zirconocene dichloride, 1-4 parts of hydrogen-chlorine ferrocene, 10-15 parts of bifenox and 12-18 parts of hydrogenated palm kernel oil. According to the high-temperature-resistant and aging-resistant cable sheath material, at the high temperature of 150 DEG C, changes of all performances are small, aging resistance is high, and the performance is stable.

Description

technical field [0001] The invention belongs to the field of cable sheath materials, and in particular relates to a high-temperature-resistant and aging-resistant cable sheath material and a preparation method thereof. Background technique [0002] Wire sheath materials play an important role in supporting and protecting cables, and mainly include rubber, plastic, nylon and other varieties. With the introduction of urbanization construction, power grid renovation project, and large-scale upgrade policy of communication equipment, the demand for wire and cable has huge potential. However, in the current existing cable sheath materials, the performance deteriorates in harsh environments such as high temperature, and problems such as aging, fracture, and tearing occur. Over time, it will not only affect electricity consumption, but will even cause safety hazards and accidents, seriously endangering people. life property health. Contents of the invention [0003] Aiming at t...
