Problems solved by technology

Among the above-mentioned requirements, the most difficult thing for people to solve is the problem of anti-wear and anti-friction. The anti-wear and anti-friction agents currently used are mainly complexes of castor oil soap and oleic acid triethanolamine and ricinoleic acid soap boric acid complexes. However, they The maximum four-ball PB value of 68Kgf force can only be provided, which limits the application range of non-petroleum hydraulic oil to a certain extent

Abstract

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.

Description

technical field [0001] The invention relates to the field of lubricating oil production, in particular to a composite extreme pressure antiwear agent and fully synthetic antiwear hydraulic oil containing the composite extreme pressure antiwear agent. Background technique [0002] In the field of hydraulic oil production, due to many deficiencies in the performance and source of mineral oil base oils, non-petroleum hydraulic oils have been more widely and deeply used. The non-petroleum hydraulic oils in the prior art mainly add various additives to water or other base fluids (including emulsions or synthetic fluids, such as high-water base fluids, water-glycol fluids, phosphate ester fluids, etc.), so that They are more suitable for use in traditional hydraulic systems. [0003] When the hydraulic system is working, the hydraulic system pushes the medium in the system forward with a certain pressure through the hydraulic pump, and controls the flow direction and flow of the ...
