NOVELTY - Preparation of power cable sleeve involves (1) kneading 100 pts. wt. fluorosilicone rubber, 30-40 pts. wt. nitrile rubber, 10-12 pts. wt. poly(arylether nitrile)-polysiloxane block copolymer, 10-12 pts. wt. amino-terminated liquid nitrile rubber, 5-7 pts. wt. butyl stearate, 2-3 pts. wt. barium stearate, 2-3 pts. wt. ethylenebis(stearamide) and 3-4 pts. wt. triethylene glycol diisooctanoate, and (2) then adding 2-3 pts. wt. organic antimony stabilizer, 1-2 pts. wt. dilauryl thiodipropionate, 2-3 pts. wt. flame retardant, 2-3 pts. wt. vulcanizing agent and 4-5 pts. wt. filler, kneading, extruding and vulcanizing. The filler is prepared by preparing nanorod attapulgite, reacting with polyacrylonitrile to obtain nanorod attapulgite-graphene composite, adding nano-aluminum nitride and nanorod attapulgite-graphene composite to absolute ethanol, ball milling, drying, sintering in nitrogen atmosphere to obtain nano-composite material, and modifying nano-composite material by cyclopentadiene. USE - Preparation of power cable sleeve (claimed). ADVANTAGE - The prepared power cable sleeve has high thermal conductivity and excellent high pressure resistance and high voltage resistance.
