Heat-curable silicone rubber composition |
摘要 |
The present invention provides a heat-curable silicone rubber composition having antistatic properties, even after secondary vulcanization at high temperatures. Specifically disclosed is a heat-curable silicone rubber composition which is obtained by adding 0.05 to 1000 ppm of (B) a poorly water-soluble or water-insoluble ionic substance whose anionic component is bis(trifluoromethanesulfonyl)imide, to 100 parts by weight of (A) a heat-curable silicone rubber. |

1. A heat-curable silicone rubber composition, prepared by adding 10 to 100 ppm of (B) a poorly water-soluble or water-insoluble ionic liquid having bis(trifluoromethanesulfonyl)imide as an anionic component, is in the liquid state at an ordinary temperature of 23° C. and has a decomposition temperature of at least 220° C. to 100 parts by weight of (A) a heat-curable silicone rubber wherein the component (B) is selected from the group consisting of 1-butyl-3-methylimidazolium.bis(trifluoromethanesulfonyl)imide, 1,2-dimethyl-3-propylimidazolium.bis(trifluoromethanesulfonyl)imide, 1-ethyl-3-methylimidazolium.bis(trifluoromethanesulfonyl)imide, 3-methyl-1-propylpyridinium.bis(trifluoromethanesulfonyl)imide, N-butyl-3-methylpyridinium.bis(trifluoromethanesulfonyl)imide, 1-butyl-1-methylpyrrolidinium.bis(trifluoromethanesulfonyl)imide, 1-vinylimidazolium.bis(trifluoromethanesulfonyl)imide, 1-allylimidazolium.bis(trifluoromethanesulfonyl)imide, 1-allyl-3-methylimidazolium.bis(trifluoromethanesulfonyl)imide and diallyldimethylammonium.bis(trifluoromethanesulfonyl)imide. |
