The invention belongs to the technical field of lubricants, and provides an ionic liquid containing metal anions, and a preparation method and application thereof. The structural general formula of the ionic liquid is A + [M]B ‑ Wherein A is + Is an imidazole cation, [ M ]]B ‑ Is metal-containing fatty acid anion. The ionic liquid can generate a nano particle or metal salt friction film in situ at a friction interface in the friction process, thereby showing excellent friction reducing and wear resisting effects, not only improving the friction reducing and wear resisting properties of lubricating oil, but also repairing the friction surface, forming an effective lubricating film on the surface of a friction pair, having excellent friction reducing and wear resisting properties, good oil solubility, simple preparation method, low cost and excellent performance. |
