▎ 摘　　要

NOVELTY - Preparation of graphene water-based lubricant comprises adding surface modifier to deionized water, stirring for 2-24 hours, adding graphite powder, stirring to uniformly disperse, and obtaining graphite dispersion; ultrasonically treating, using three ultrasonic cavitation device, standing for 12-48 hours, and taking upper layer solution; and putting upper layer solution through pipe, split charging, centrifugally separating at 500-5000 revolutions/minute, processing for 30-180 minutes, and taking upper layer clear liquid. USE - Method for preparing graphene water-based lubricant (claimed). ADVANTAGE - The method is simple and easy to operate; and produces lubricant with improved anti-wear anti-friction property. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the preparation of graphene water-based lubricant (Drawing includes non-English language text).
