A lubricating oil friction modifier and a preparation method therefor and use thereof are provided. The lubricating oil friction modifier has a chemical formula of AxBy+(C−)y. In the formula, A is a perfluoropolyether acyl group, By+ represents a cationic group having x amino groups and y ammonium ions, C− is BF4−, PF6−, AsF6−, FAP−, TFSI−, Mn2O4 or ClO4−, x is an integer greater than or equal to 1, y is an integer greater than or equal to 1, and x+y≥2. The lubricating oil friction modifier has a good solubility with fluorine oil and fluorine grease, will not precipitate in the fluorine oil and the fluorine grease after being added, and can significantly improve the wear resistance of a lubricating oil such as the fluorine oil and the fluorine grease.
A lubricating oil friction modifier, having a chemical formula of AxBy+(C−)y, wherein, A represents a perfluoropolyether acyl group, By+ represents a cationic group having x amino groups and y ammonium ions, C− is BF4− (boron tetrafluoride anion), PF6− (hexafluorophosphate anion), AsF6− (hexafluoroarsenate anion), FAP− (trifluorotri(pentafluoroethyl)phosphate anion), TFSI− (bistrifluoromethylsulfonimide anion), Mn2O4− (manganate) or ClO4− (perchlorate), x is an integer greater than or equal to 1, y is an integer greater than or equal to 1, and x+y≥2.
