▎ 摘　　要

NOVELTY - Preparing graphene grease comprising 100 pts. wt. grease and 0.001-0.1 pts. wt. surface modified graphene powder, comprises surface modifying graphene powder using solvent method by dispersing graphene in a solvent containing 0.5-2% modified coupling agent at 30-60 degrees C, filtering and drying to obtain the modified graphene powder. USE - The method is useful for preparing graphene grease (claimed). ADVANTAGE - The method: utilizes thin-, ultra hard-, ultra-smooth-, and corrosion resistance graphene which exhibits high-temperature characteristics, and energy-saving materials; and ensures product with improved lubricating properties and reduced friction and wear of mechanical moving surface.
