▎ 摘　　要

NOVELTY - A modified graphene lubricating oil with good dispersibility 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 aminosilated graphene. USE - Modified graphene lubricating oil with good dispersibility. ADVANTAGE - The oil has strong lubricity and anti-friction property, improves lubricating performance, reduces resistance and friction coefficient, and prolongs service life of mechanical parts to save energy. The method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of modified graphene lubricating oil with good dispersibility comprising mixing modified graphene oxide and dispersant into base oil, uniformly stirring to obtain mixture, and homogenizing and colloid treating.
