Preparation and conductive silicone rubber of the conductive silicone rubber composition

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid conductive silicone rubber composition from which a conductive silicone rubber having a dispersion of volume resistivity within a permissible range when it is cured can be obtained, the liquid conductive silicone rubber composition obtained by the method like this, and a conductive silicone rubber and a conductive roll obtained by curing the liquid conductive silicone rubber composition.;SOLUTION: The method of manufacturing the conductive silicone rubber composition includes a process (1) for preparing an admixture by kneading an alkenyl group-containing polyorganosiloxane (A) which has two or more alkenyl groups bonding to silicon atoms and of which the viscosity at 23 °C is 0.1 to 300 Pa s and a conductive carbon black (B) so that the degree of plasticity at 23 °C is 100 to 1,000, and a process (2) for blending the added (A) with it, and the method is characterised in that the liquid conductive silicone rubber having an apparent viscosity of 1 to 1,000 Pa s at 23 °C is prepared.;COPYRIGHT: (C)2005,JPO&NCIPI
