<p><P>PROBLEM TO BE SOLVED: To provide a fluorine-based lubricant composition for reducing the abrasion of sliding members such as electric contacts having a noble metal surface including a gold or silver plating surface, a copper surface or a copper alloy surface. <P>SOLUTION: The fluorine-based lubricant composition comprises a base oil, and in the base oil, a thickening agent and as an additive the fluorine-containing compound represented by general formula: CF<SB>3</SB>(CF<SB>2</SB>)<SB>n</SB>O(CF<SB>2</SB>O)<SB>p</SB>(C<SB>2</SB>F<SB>4</SB>O)<SB>q</SB>(C<SB>3</SB>F<SB>6</SB>O)<SB>r</SB>RfCONHAr (wherein Ar is a 2-benzoimidazole group; Rf is a 1-2C fluorocarbon group; n is 0, 1 or 2; p, q and r are each an integer while satisfying p+q+r≤100 and one or two of p, q and r may be 0; the CF<SB>2</SB>O group, the C<SB>2</SB>F<SB>4</SB>O group and the C<SB>3</SB>F<SB>6</SB>O group are the groups bonded randomly to the main chain thereof). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
