Abstract: A lubricant composition includes a base oil and melamine cyanurate. The base oil includes a perfluoropolyether oil having a straight chain structure. The lubricant composition is for one of a resin-resin sliding section and a resin-metal sliding section. A melamine cyanurate content is within a range of 1-20% by mass with respect to a sum of the base oil and melamine cyanurate.

Abstract: Disclosed is an electroconductive grease comprising a fluorine oil, an electroconductive material, and a thickening agent, the electroconductive grease containing 5 to 20 wt. % of carbon black having a DBP oil absorption amount of 250 ml/100 g or less as the electroconductive material, and 2 to 15 wt. % of fluorine-containing resin particles having an average primary particle size of 1.0 ?m or less as the thickening agent. The electroconductive grease comprises carbon black having specific properties, and fluorine-containing resin particles, preferably PTFE particles, having an average primary particle size of 1.0 ?m or less, and therefore exhibits excellent oil separation characteristics, namely, a remarkably lower degree of oil separation, which can also be reduced to 10 wt. % or less.

Abstract: A fluorine-based lubricant composition comprising a base oil and a fluorine-containing compound represented by the general formula: CF3(CF2)n O(CF2O)p(C2F4O)q(C3F6O)rRfCONHAr (wherein, Ar is a 2-benzimidazole group, Rf is a fluorocarbon group of carbon number of from 1 or 2, n is 0, 1 or 2, p, q and r are an integer satisfying the condition p+q+r?100, where one or two of p, q and r may be 0, and the CF2O group, the CF2O4 group and the C3F6O group are the groups bound randomly in the main chain) as an additive containing in the base oil. The fluorine-based lubricant composition has an improved long term anti-rust property and thermal resistance property, and further the fluorine-based lubricant composition obtained by adding a thickening agent to the composition reduces abrasion of the sliding member such as electric contact having a noble metal surface including a gold or silver plating surface, a copper surface and a copper alloy surface.
