Abstract

The invention discloses a chlorosulfonated polyethylene cable sheath material and a preparation method thereof. The cable sheath material comprises the following raw materials: chlorosulfonated polyethylene, impact-resistant polystyrene, nano calcium carbonate, siliceous rock powder, modified zinc borate, ethyl carbamate, an accelerant CZ, a silane coupling agent KH550, epoxidized butyl stearate, thiodipropionate, alkylphenol polyoxyethylene and diisobutyl phthalate. By taking the chlorosulfonated polyethylene as a main material, the cable sheath material is excellent in aging resistance, heat resistance, low-temperature resistance, oil resistance and electrical-insulation resistance. By taking the nano calcium carbonate as a reinforcing agent and modifying the zinc borate serving as a fire retardant, the fire resistance of the cable sheath is improved greatly, so that the cable sheath is obvious in fire resistance.

Description
