preparation example Construction

[0017] The preparation method of the organic nitrogen-molybdenum fullerene lubricant of the present invention is based on fullerene C60, reacts with concentrated nitric acid and concentrated hydrochloric acid, then adds ricinoleic acid, and adopts the method of adjusting pH value to obtain polar modified fullerene , and then react with succinamide and non-sulfur phosphorus organic molybdenum, and take a two-step partial pressure decompression method to prepare an organic nitrogen molybdenum fullerene lubricant, including the following steps:

[0018] 1) Synthesis of polar modified fullerenes

[0019] Put fullerene C60, concentrated nitric acid, and concentrated hydrochloric acid in a container, react at 90°C to 100°C under vacuum for 2 to 3 hours, then wash with water and alcohol, adjust the pH to 6.5 to 7, and add castor oil acid, continue to react at a temperature of 180-200°C for 3-4 hours, then vacuum filter to obtain a precipitate, wash with alcohol and water until neutra...

Abstract

The invention discloses organic nitrogen molybdenum fullerene lubricant and a preparing method thereof. The lubricant is prepared through polarity modification fullerene C60, succinamide and sulfur-and-phosphorus-free organic molybdenum, wherein the weight ratio of the polarity modification fullerene C60 to the succinamide to the sulfur-and-phosphorus-free organic molybdenum is 1 to 5-8 to 30-35. The polarity modification fullerene C60 is prepared through fullerene C60, concentrated nitric acid, concentrated hydrochloric acid and ricinoleic acid in a reacted mode. The additive is the organic nitrogen molybdenum fullerene lubricant, serves as friction improving agent, antiwear agent and antioxidant of lubricating oil and particularly serves as friction improving agent, antiwear agent and antioxidant of lubricating oil for internal combustion engines, and the oil saving effect is remarkable; as sulfur, phosphorus and chlorine are free, the additive further has the advantages that energy is saved, and the environment is protected; the production method is simple, cost is low, the oil solubility is good, and productivity is high.

Description

technical field [0001] The invention relates to an organic nitrogen molybdenum fullerene lubricant and a preparation method thereof, in particular to an oil-soluble organic nitrogen molybdenum fullerene 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] Non-sulfur phosphor...
