▎ 摘  要

NOVELTY - Preparing anti-oxidation and anti-rust oil synergized by sulfide graphene comprises (i) preparing a graphene dispersion; (ii) adding organic alcohol and phosphorus pentasulfide into the graphene dispersion liquid, stirring, reacting, adding base oil and carrying out vacuum distillation to obtain the additive mixture containing graphene sulfide; and (iii) adding 1-5 wt.% vulcanized graphene additive mixture obtained into the rust-proof oil base oil. USE - The method is useful for preparing anti-oxidation and anti-rust oil synergized by sulfide graphene. ADVANTAGE - The method: can solve the problem of poor dispersion of graphene or modified graphene as an additive in anti-oxidation and anti-rust oil and easy occurrence of agglomeration, aggregation, precipitation and anti-rust film falling off from the metal surface; and improves the adsorption of graphene on the metal surface and anti-friction and lubricating properties of the anti-oxidation and anti-rust oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for anti-oxidation and anti-rust oil synergized by sulfide graphene, prepared as mentioned above.
