▎ 摘　　要

NOVELTY - Slurry comprises oil-soluble hydroxylamine, modified zirconium phosphate dispersed in the oil-soluble hydroxyamine, graphene and poly (isobutylene-b-propanol-b-isobutylene) block copolymer. USE - The slurry is useful in lubricating oil and grease (claimed). ADVANTAGE - The slurry has better dispersion stability and lower coefficient of friction resistanc; and retains the phenomenon of precipitation and dispersion from occurring for a long time. The method: has simple and easy operation; utilizes easily available raw materials; and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing slurry comprising (i) mixing modified zirconium phosphate and poly (isobutylene-b-propanol-b-isobutylene) block copolymer to obtain mixture A, (ii) mixing graphene dispersion liquid and the oil-soluble hydroxyamine to obtain mixture B, and (iii) mixing obtained mixture A and mixture B, and dispersing to obtain final product, where the slurry stably disperses modified zirconium phosphate and graphene at the same time,.
