▎ 摘　　要

NOVELTY - Preparation of graphene oil antiwear agent comprises dissolving graphene oxide in toluene, ultrasonically dispersing to form graphene oxide dispersion liquid, dissolving sodium azide and cyanuric chloride in toluene to form a reaction liquid, adding the reaction liquid to the graphene oxide dispersion liquid, conducting secondary ultrasonic dispersion to form mixed liquid, adding the mixed liquid into a reaction kettle, carrying out solvothermal reaction, preparing carbon nitride modified graphene composite material, centrifuging, and washing. USE - The method is for preparation of graphene oil antiwear agent. ADVANTAGE - The carbon nitride nanotube modified graphene has better antiwear property and dispersibility.
