Preparation method and device of double-antioxidant system extreme pressure anti-wear lubricating oil

The invention relates to the technical field of lubricating oil, in particular to a preparation method and device of double-antioxidant-system extreme pressure anti-wear lubricating oil, the device comprises a stirring tank, a cover plate, a driving assembly, a rotating shaft, a disc, a plurality of stirring blades, an oil discharge pipe, a diaphragm pump, a hose and a hook, the driving assembly is used for driving the rotating shaft to rotate so as to drive the stirring blades to rotate, and the lubricating oil is stirred; the oil discharging pipe is located at the bottom and used for guiding out lubricating oil and pumping the lubricating oil out through the diaphragm pump, the hose is hung on the stirring tank through the hook, the pumped lubricating oil enters again from the upper portion to achieve the circulating mixing effect, the stirring blades are half submerged in the lubricating oil, resistance is small, and the load on the rotating shaft is small. Meanwhile, the lubricating oil below can be stirr
