Title:
LUBRICATING OIL FRICTION MODIFIER AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/279707
Kind Code:
A1
Abstract:
The present invention relates to a lubricating oil friction modifier and a preparation method therefor and an application thereof. The chemical formula of the lubricating oil friction modifier is AxBy+(C-)y, wherein A is a perfluoropolyether oleoyl group, By+ represents a cationic group having x amino groups and y ammonium ions, C- is BF4
-, PF6
-, AsF6
-, FAP-, TFSI-, Mn2O4
-, and 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 of the present invention has good solubility with fluorine oil and fluorine grease, does 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.
