Abstract

The invention discloses a cable sheath material containing modified methyl vinyl silicone rubber and a preparation method thereof. The cable sheath material comprising raw materials of: the modified methyl vinyl silicone rubber, impact-resistant polystyrene, calcium carbonate, diatomite, aluminium nitride, accelerant DM, accelerant TMTD, Bis(P,P-bis-ethylhexyl diphosphato)ethanediolato titanate, calcium ricinoleate, diphenylamine, tributyl citrate and tritolyl phosphate. The cable sheath material containing the modified methyl vinyl silicone rubber and the preparation method thereof employ the modified methyl vinyl silicone rubber as a main material; the mechanical properties of the modified methyl vinyl silicone rubber are greatly modified by modifying the methyl vinyl silicone rubber; the cable sheath material has better mechanical properties, and has the characteristics of low smoke, being free of halogen and high insulation resistance; and calcium carbonate is used as a reinforcing agent in raw materials, and diatomite and aluminium nitride are used as filling materials.

Description

technical field [0001] The invention relates to a cable sheath material, in particular to a cable sheath material containing modified methyl vinyl silicone rubber and a preparation method thereof.
