NOVELTY - Preparation of diene graphene lubricating oil comprises assembling material, and mixing multilayer graphene, graphene oxide, graphene dispersant and diester base oil; emulsifying and dispersing including ultrasonic vibration, low speed pre-mixing, emulsification and high-speed dispersion; repeating steps until black becomes dark green solution; filtering dark green solution to obtain concentrated oil; and preparing and mixing concentrated oil and diester base oil, adding lubricating oil reinforcing agent, adsorbent, molybdenum, zinc and phosphorus, and stirring. USE - The method is used for preparing diene graphene lubricating oil. ADVANTAGE - The lubricating oil can convert frictional resistance into power, and achieve energy saving and emission reduction.
