However, there are often various limitations or defects in the above-mentioned nano lubricating oil additives
[0003] For example, nano-graphite flakes have high wear-reducing properties, but poor wear-resisting properties, and are difficult to disperse, and are prone to agglomeration and segregation in the actual use of the engine, making the lubricating oil additives based on nano-graphite flakes Effectiveness is greatly limited and can even have negative effects
Although the use of graphene instead of nano-graphite can theoretically obtain a better lubricating effect per unit mass of additives, it cannot overcome the shortage of extreme pressure properties, and the long-term stability of graphene additives dispersed in base oils is rarely reported, especially In the actual use of high-power or high-heat (such as with Turbo) engines,

The invention relates to the technical field of lubricating oil, in particular to a high-performance lubricating oil based on graphene and magnetic rare earth nano-composite additives. The present invention utilizes the synergistic lubrication of the composite additives of nano-graphene and NdFeB to overcome the deficiency of each single additive in the use of lubricating oil, and has the following advantages compared with various existing lubricating oil products: first, its comprehensive performance is better At the same time, it has good intelligent repair characteristics, which can repair the worn out engine; in addition, it also has great advantages in environmental protection.
Description
technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high-performance lubricating oil based on graphene and magnetic rare earth nano-composite additives. Background technique [0002] In recent years, nano-additives have become a scientific hotspot in the field of lubricating oil additives, and excellent lubricating oil additives based on nano-rare earth compounds, nano-graphite flakes, molybdenum disulfide, etc. have been produced, which has pushed lubricating oil technology to a new development space. However, these above-mentioned nano lubricating oil additives often have various limitations or defects. [0003] For example, nano-graphite flakes have high wear-reducing properties, but poor wear-resisting properties, and are difficult to disperse, and are prone to agglomeration and segregation in the actual use of the engine, making the lubricating oil additives based on nano-graphite flakes Effectiveness is greatly l...
