▎ 摘　　要

NOVELTY - Method for producing liquid-like graphene-based water-based lubricant, involves dissolving oxidized graphene in deionized water, performing ultrasonic dispersion of the mixture, adding sulfonic acid base modifier to the mixture, adding alkaline solution, transferring the mixture into round bottom flask, filtering, washing, dissolving the filtrate in deionized water, performing ion exchange process of the mixture, adjusting pH, adding the polyoxyethylene alkylamine aqueous solution, reacting, drying and cooling the dried product. USE - The method is useful for producing liquid-like graphene-based water-based lubricant which is used as water friction additive (all claimed). DETAILED DESCRIPTION - Method for producing liquid-like graphene-based water-based lubricant, involves (a) dissolving oxidized graphene in deionized water, performing ultrasonic dispersion of the mixture, adding sulfonic acid base modifier to the mixture, adding alkaline solution to adjust the alkalinity, and transferring the mixture into round bottom flask, and (b) filtering the solution, washing the filtrate, dissolving the filtrate in deionized water, performing ion exchange process of the mixture to replace metal cation in the solution, adjusting pH of the mixture, adding the polyoxyethylene alkylamine aqueous solution to the reaction solution for acid and alkali, reacting the mixture, drying the mixture and cooling the dried product. An INDEPENDENT CLAIM is included for liquid-like graphene-based water-based lubricant, which is prepared by the method.
