Abstract

The invention relates to nanometer magnetic lubricating oil and a preparation method thereof, and belongs to the technical field of lubricating oils. According to the present invention, superparamagnetic Fe3O4 nanoparticles are prepared by using ferric chloride hexahydrate is used as a raw material and using ethylene glycol as a reducing agent, and the surface of the superparamagnetic Fe3O4 nanoparticles is coated with an amorphous carbon layer by using glucose as a carbon source, such that the aggregation precipitation of magnetic particles is prevented, magnetic particles can have extremelygood dispersion property and extremely good stability in base oil, and the effectively dispersion and recycling in lubricating oil and ethanol can be achieved; the prepared lubricating oil has magnetic property and fluidity under the non-uniform magnetic field effect, can accurately fill the lubricating surface to achieve continuous lubricating, and can counteract the effects of gravity and centripetal force, is not easily leaked, and can prevent external pollution during the lubricating; and the nanometer magnetic lubricating oil cannot precipitate after long-term placing, can prolong the service life of lubricating oil, can be widely used for mechanical lubrication, and further has advantages of energy saving, consumption reducing and wide application prospect.

Description

technical field [0001] The invention relates to a nanometer magnetic lubricating oil and a preparation method thereof, belonging to the technical field of lubricating oil. Background technique [0002] According to statistics, friction consumes one-third to one-half of the world's primary energy, and 80% of mechanical wear is caused by wear. In 2015, the loss caused by friction and wear was nearly 3 trillion yuan. Waste of resources has become an important issue for improving the environment. The lubricating effect of lubricating oil is the main method to reduce friction and wear. Adding anti-friction and antiwear agents to lubricating oil can effectively improve the performance of lubricating oil. In recent years, environmental issues have become the focus of social attention, and science and technology have continued to develop rapidly. People have higher and higher requirements for lubricating oils, and the development of lubricating oil additives tends to be high-qu...
