NOVELTY - A high dispersing modified graphene lubricating oil comprises 0.3-1.5 pts. wt. modified graphene oxide, 0.3-1.5 pts. wt. dispersant and 100 pts. wt. base oil. The modified graphene oxide is quaternary ammonium salt modified graphene oxide. USE - High dispersing modified graphene lubricating oil (claimed). ADVANTAGE - The high dispersing modified graphene lubricating oil has reasonable formula, excellent stability, improved lubrication performance, low movement resistance, low friction coefficient, wear resistance, long service life and high energy-saving effect, and is prepared by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of high dispersing modified graphene lubricating oil, which involves adding modified graphene oxide and dispersant to base oil according to proportion, uniformly stirring to obtain mixture and carrying out homogenizing and colloidization treatment the mixture to obtain final product.
