Composite extreme pressure anti-wear agent and total-synthesis anti-wear hydraulic oil containing same

The invention discloses a composite extreme pressure anti-wear agent and total-synthesis anti-wear hydraulic oil containing the composite extreme pressure anti-wear agent, belonging to the field of production of lubricating oil. The hydraulic oil is mainly prepared by mixing aqueous base oil and the composite extreme pressure anti-wear agent, wherein the composite extreme pressure anti-wear agent is a compound of two kinds of imidazolyl tetrafluoroborate ion liquid. Compared with the prior art, the total-synthesis anti-wear hydraulic oil has the characteristics of excellent lubricating performance, energy saving, environment friendliness and the like and has high popularization and application values.
