Abstract

The invention discloses a fullerene, boron and nitrogen containing lubricant and a preparation method thereof. An additive is prepared from polar modified fullerene C60, methyl laurate and nitrogen-containing borate, wherein a weight ratio of polar modified fullerene C60 to methyl laurate to nitrogen-containing borate is 1: (2-3): (20-25). The polar modified fullerene C60 is prepared from fullerene C60, concentrated sulfuric acid, concentrated hydrochloric acid and tall oil acid through reaction. The additive is the fullerene, boron and nitrogen containing lubricant, serves as a friction modifier, an anti-wear agent and an antioxidant of lubricating oil especially lubricating oil for an internal combustion engine, has remarkable friction reduction and oil saving effects, and further has the advantages of energy saving and environment protection due to absence of sulfur, phosphorus and chlorine; a production method is simple, the cost is low, oil solubility is good, and the yield is high.

Description

technical field [0001] The invention relates to a fullerene boron nitrogen lubricant and a preparation method thereof, in particular to an oil-soluble fullerene boron nitrogen lubricant compound and a preparation method thereof. Background technique [0002] Due to its unique structural characteristics, fullerene C60 has become a research hotspot in many disciplines and related application fields such as physics, chemistry, materials science and life science in recent years. It is a quasi-spherical particle composed of concentric closed shells, and its interlayer spacing is 0.349nm, which is close to that of graphite at 0.336nm. It is a lubricant with excellent performance. [0003] If fullerene is used in lubricating oil, it will greatly improve the anti-wear and anti-friction properties of lubricating oil and effectively protect the engine. However, because fullerene is a solid, its use in lubricating oil is limited. [0004] Nitrogen-containing borate is the most high-en...
