Abstract
PURPOSE: To obtain a cured article having a steady electrical conductivity, by incorporating a liquid polybutadiene or its hydrogenated one as a matrix with specific amounts of a conductive filler and a crosslinking agent.
CONSTITUTION: (A) A liquid polybutadiene rubber having 1.8W3.0 terminal hydroxyl groups on the average in one molecule and an average molecular weight of 500W8,000 or its hydrogenated one is incorporated with (B)a conductive filler, e.g. carbon black, carbon fiber, various types of metal powder, etc. at a weight ratio of (A) to (|B) of 99:1W10:90, and further (C) a curing agent, e.g. 4,4'-diphenylmethane diisocyanate, etc. at a weight ratio of (A) to (C) of 98:2W60:40 and cured. To shorten the curing time, 0.01W1% of dibutyltin dilaurate, etc. is preferably added as a catalyst. The cured article thus obtained has a remarkably stabilized electrical conductivity free from unnatural strain due to the poor orientation of the filler.
