Abstract

The invention provides a lubricating oil modifying aid. The lubricating oil modifying aid comprises fluorinated expanded graphite as a supporter and permanent magnet material particles adsorbed on thesurface of the supporter, and the lubricating oil modifying aid is worm-shaped. The lubricating oil modifying aid is low in friction coefficient, good in lubricating effect and high in adsorption capacity, modification treatment of lubricating oil is facilitated, the lubricating performance of lubricating oil under the low-temperature condition is improved, and therefore the problem of resonancesqueal caused by starting impact at the low temperature and the normal temperature is completely eradicated.

Description

technical field [0001] The application belongs to the technical field of lubricating oil, and in particular relates to a lubricating oil modification aid, a preparation method thereof, and a modified lubricating oil. Background technique [0002] As far as the current automobile industry is concerned, the supporting small motors such as the electronic parking system (EPB) generally adopt the design of powder metallurgy bearings at the non-torque output end. Powder metallurgy bearing is a kind of porous material. The load and speed of small motors in automobiles determine that it is mostly Cu-Zn system. It can use capillary action to suck lubricating oil under vacuum conditions, and then pump and Thermal expansion is released to form a lubricating film. Based on safety considerations, perfluoropolyether, which has stable chemical properties and superior comprehensive lubricating properties, is currently used as the lubricating oil for powder metallurgy bearings in the mainst...
