Abstract

The invention discloses a methyl vinyl silicone rubber cable sheath material of modified nanocarbon, and a preparation method thereof. Raw material composing the sheath material comprise methyl vinyl silicone rubber, low density polyethylene, nano-clay, modified nanocarbon, antimony trioxide, an accelerant DM, 2-mercaptobenzimidazole, vinyltri(beta-methoxyethoxy)silane, a rare earth stabilizer, resorcinol, fatty alcohol polyoxyethylene ether and tritolyl phosphate. The sheath material is based on the methyl vinyl silicone rubber, so the tensile strength, the elongation at break, the elongation at break after ageing and the insulation rate of a cable sheath are excellent; and the modification treatment of the filler nanocarbon enhances the internal connection of the cable sheath, so the break of the cable sheath can be effectively prevented, and the service life of the cable sheath is prolonged.
