▎ 摘　　要

NOVELTY - Preparing high-pressure anti-wear hydraulic oil containing esterified modified graphene oxide comprises (A) preparing the graphene oxide-polyol ester dispersion liquid of esterification modification, and (B) adding the esterification-modified graphene oxide dispersion liquid obtained in step A into the base oil at 1-5% by mass and mixing to obtain a high-pressure anti-wear hydraulic oil containing esterification-modified graphene oxide. USE - The method is useful for preparing high-pressure anti-wear hydraulic oil containing esterified modified graphene oxide. ADVANTAGE - The method significantly improves the anti-pressure and anti-friction capabilities of the anti-wear hydraulic oil, can efficiently prolong the oxidation stability of hydraulic oil, and solves the adverse effects of traditional anti-wear additives on oil product anti-corrosion, anti-emulsification and other indicators when the amount of use is increased. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high-pressure anti-wear hydraulic oil containing esterified modified graphene oxide.
