NOVELTY - A modified graphene lubricating oil comprises 0.3-1.5 pts. wt. modified graphene and dispersing agent mixture, 0.5-1 pts. wt. compatibilizer, 0.8-1.5 pts. wt. antifoaming agent, 0.2-0.6 pts. wt. preservative, and 1-10 pts. wt. base oil. USE - A modified graphene lubricating oil. ADVANTAGE - The lubricating oil has high dispersibility, high affinity, excellent antifriction and friction-reducing effect, good mechanical protection, excellent stability and good anti-oxidation ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing a modified graphene lubricating oil comprising mixing raw materials, stirring at a speed of 1000 revolutions/minute (rpm) for 0.5 hour, and subjecting to ultrasonic dispersion at a frequency of 20 kHz to 1 MHz, power of 200-500 W and speed of 250-350 rpm for 1-2 hours.
