Embodiment 1

[0032] 1. Preparation of N-oleoylserine: Weigh 2.82g (0.01mol) of oleic acid and PCl 3 2.06g was placed in a dry three-neck flask equipped with a reflux condenser, heated to reflux for 4h, and the excess PCl was evaporated 3 , Distilled under reduced pressure to obtain oleoyl chloride. React oleoyl chloride with 1.05g of serine in an alkaline solution of pH 8-10 at 15-20°C for 4-5 hours. After the reaction, let it stand for cooling, acidify the reaction liquid with hydrochloric acid to pH 1-2, wash the oil layer with water and petroleum ether, and dry it to obtain N-oleoylserine.

[0033] 2.C 60Preparation of N-oleoylserine derivatives: Weigh 720mgC 60 Add it into 150ml of xylene, ultrasonically disperse for 1.5h, add 2g of N-oleoylserine, fill with nitrogen, react at 120°C for 8h, filter and wash four times with absolute ethanol, and dry under vacuum at 60°C to obtain C 60 N-oleoylserine derivatives.

[0034] 3. Preparation of environment-friendly high anti-wear lubricat...

Embodiment 2

[0036] Steps 1 and 2 are the same as above. Take 10g of sulfurized castor oil, 75g of trimethylolpropane ester, and a viscosity of 2mm at 100°C 2 / sPA0 11g in a three-necked flask, stirred and heated to 65°C for 1h, added 0.5g of methylene bisphenol antioxidant, 1.0g of low-basic calcium sulfonate rust inhibitor with a base value of 60mg KOH / g, continued to stir for 2h, and then Add the C prepared above 60 N-oleoylserine derivative 2.5g, ultrasonic dispersion 2h, the product is obtained.

Abstract

The invention discloses environment-friendly high-wear-resistance lubricating oil and a preparation method thereof. The lubricating oil comprises base oil, an antirust agent, an antioxidant and an anti-wear agent at extreme pressure, wherein the anti-wear agent at extreme pressure is a synthesized fullerene C60N-acyl amino acid derivative. The environment-friendly high-wear-resistance lubricating oil and the preparation method thereof have the advantages that the product has high biodegradation ratio, is applicable to any occasions and has extremely low friction coefficient; the product does not contain elements such as sulfur and phosphorus, so when the environment-friendly high-wear-resistance lubricating oil is used as internal combustion engine oil, pollutants discharged by an internal combustion engine are reduced and the discharge requirement above national IV can be met.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to environment-friendly and highly anti-wear lubricants and a preparation method thereof. technical background [0002] Lubricants are widely used in aviation, transportation, metallurgy, coal, construction and other industries. Traditional lubricating oil is a lubricant based on mineral oil. In some special occasions, such as hydraulic oil, saw chain oil, outboard two-stroke engine oil, open gear oil and other open systems or disposable circulation systems, Due to transportation, leakage, splashing, natural replacement and other reasons, lubricating oil will inevitably be discharged directly into the environment, while mineral-based lubricating oil has poor degradation ability in the natural environment and accumulates in the environment, which is harmful to animals, plants and The human living environment has caused great pollution, especially in environmentally sensitive areas such as ...
