Abstract
The invention relates to a lubricating oil base oil based on a synthetic ester compound of gallic acid. The lubricating oil base oil includes the compound shown as general formula (I), wherein R1 and R2 are independently selected from alkyl of C1-C18 respectively. The lubricating oil base oil based on the synthetic ester compound of gallic acid provided by the invention is prepared from the natural and renewable resource gallic acid, has high flash point and thermal stability, good viscosity-temperature performance, and has excellent friction reduction and antiwear properties as a lubricant of steel / steel and steel / copper friction pairs.
Description
technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil base oil based on a synthetic ester compound of natural product gallic acid and an application thereof. Background technique [0002] Synthetic ester lubricating oil is a class of organic compounds obtained by esterification and dehydration of organic acids and organic alcohols under the action of catalysts. It is a lubricating oil that was born and developed with the advancement of aero-engine technology and the demand for high-performance lubricating materials. Synthetic ester lubricating oil has excellent lubricating performance because of the polar ester group in the molecule, which can effectively adsorb on the surface of the friction pair material. At the same time, they also have excellent high and low temperature properties, viscosity-temperature properties, thermal stability, oxidation stability, low volatility, low biological toxicity and good...
