Title:
ELECTROCONDUCTIVE LIQUID SILICONE RUBBER COMPOSITION, AND NORMAL-TEMPERATURE SHRINKABLE RUBBER MEMBER FOR HIGH-VOLTAGE CABLE
Document Type and Number:
Japanese Patent JP2015057763
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electroconductive liquid silicone rubber composition which has low viscosity and is such an addition cure type that a cured product excellent in productivity, workability, electric characteristics and rubber strength is obtained, and to provide a normal-temperature shrinkable rubber member for high-voltage cables, which member comprises a cured/molded product of the electroconductive liquid silicone rubber composition.SOLUTION: The electroconductive liquid silicone rubber composition is a composition for the normal-temperature shrinkable rubber member for high-voltage cables, which member is attached to a juncture or terminal of the high-voltage cable to hold the juncture or terminal. The electroconductive liquid silicone rubber composition contains: (A) an organopolysiloxane having two or more silicon atom-bonded alkenyl groups in one molecule thereof; (B) an organohydrogenpolysiloxane having three or more silicon atom-bonded hydrogen atoms in one molecule thereof; (C) fumed silica having 50-400 m/g BED method specific surface area; (D) furnace black having 0.1 mass% or lower sulfur content; and (E) an addition reaction catalyst, and has 200-2,000 Pa-s viscosity at a shear rate of 0.9 sat 23°C.
