Abstract
The invention discloses a motor lubricating grease and a preparation method thereof. The motor lubricating grease is composed of base oil, a thickener and an additive, wherein the thickener accounts for 18-22 wt% of the base oil, and the additive accounts for 1.2-1.8 wt% of the base oil. The base oil is a mixture of silicon oil and mineral oil; the thickener is prepared from lithium hydroxide, stearic acid, naphthenic acid and acetic acid; and the additive is a mixture of flake graphite, molybdenum disulfide, phosphate and potassium triborate. The preparation method is simple and adopts the reasonable raw material proportioning; and by using the thickener prepared from the lithium hydroxide, stearic acid, naphthenic acid and acetic acid, the thickness of the lubricating grease is slightly changed under temperature change conditions, thereby satisfying the application at high temperature. The flake graphite, molybdenum disulfide, phosphate and potassium triborate are added to enhance the friction resistance of the lubricating grease, so that the lubricating grease is suitable for the working environment of the motor.
