Description
Technical Field
The invention relates to the technical field of preparation methods of lubricating oil additives, in particular to a nano graphitized carbon ball lubricating oil additive with an anti-corrosion performance, and a preparation method and application thereof.
Background
In recent years, economic losses caused by wear failure of devices in the fields of metallurgy, mining chemistry and the like still account for a small ratio of total values, so that reducing fatigue wear of motion-side surfaces in complex mechanical systems and mechanical energy consumption are just a big research problem. Therefore, in order to adapt to different motion environments and motion modes and various contact forms, especially liquid lubrication in friction of high-speed motion, many researchers have proposed a solution to improve the friction condition by using nano-sized materials as lubricating oil additives based on conventional lubricating grease. However, the problems of material loss, equipment failure, energy consumption and the like are also caused by the reasons of abrasion, fatigue, fracture and the like of transmission parts caused by corrosion under the severe conditions of high speed, high load, high temperature and the like, and the production development and technological progress are seriously hindered, so that the solution of the corrosion inhibition problem based on the friction behavior becomes a hot point of research at home and abroad.
The particularity of the structure of the nano-sized material leads the nano-sized material to have large specific surface, small-size effect, interface effect, quantum effect and quantum tunneling effect, and the effects endow the nano-sized material with better wear resistance, high bearing capacity and environmental friendliness than the traditional lubricating oil additive, while in the nano-sized material, the carbon nano-sized material is more suitable for various tribological applications in dry lubricants and oil lubricants due to relatively low friction coefficient and good wear resistance. Meanwhile, due to the common special structure and the characteristic of high specific surface area, various carbon nano materials are paid more and more attention to the field of corrosion prevention as micro-nano loaders.
Graphite in the prior art is widely used as a good lubricating and self-lubricating material for a lubricating oil additive, and the graphite in the prior art cannot be used for corrosion prevention of devices while realizing wear resistance and wear reduction, so that the service life of instruments is limited.
