Abstract

The invention provides a polyalkylcyclopentane lubricating oil composition, and a preparation method and an application thereof, and belongs to the field of liquid lubrication. Guerbet alcohol Guerbetacid ester and tricresyl phosphate are ester compounds and can be well mixed and dissolved to form a composite additive; and the base oil and the Guerbet alcohol Guerbet acid ester have similar longside chain structures, so the polyalkylcyclopentane lubricating oil composition has the advantages of good compatibility, extremely wide liquid temperature range, extremely low volatilization loss, excellent lubricating performance and excellent high and low temperature performances, and can be used for liquid lubrication under harsh conditions such as a micro electro mechanical system and space machinery.

Description

technical field [0001] The invention relates to the technical field of liquid lubrication, in particular to a polyalkylcyclopentane lubricating oil composition and a preparation method and application thereof. Background technique [0002] Polyalkylcyclopentanes (MACs) have low volatility, high thermal and chemical stability, and are widely used in lubrication under harsh conditions such as MEMS and space machinery. The core five-membered ring of MACs endows this class of compounds with high thermal and chemical stability. However, since these compounds are non-polar compounds, the adsorption force to the substrate is weak, and the boundary lubricant film is easily destroyed during the friction process, so their extreme pressure performance is relatively weak. In order to meet the application requirements under special working conditions, adding appropriate anti-wear additives will help improve the tribological properties of MACs. [0003] Traditional antiwear additives su...
