▎ 摘　　要

NOVELTY - Titanate-modified graphene oxide slurry is obtained by dispersing graphene oxide and a titanate coupling agent through ultrasound and taking an upper slurry, where the solid content of the titanate-modified graphene oxide slurry is 60%. USE - Titanate-modified graphene oxide slurry. ADVANTAGE - The titanate-modified graphene oxide slurry has excellent dispersibility, stability, and abrasion resistance, improves grafting efficiency of graphene oxide and protects intrinsic structure and performance of graphene-based materials, and maintains long-term stability and no sedimentation in a high temperature sedimentation performance test. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a lubricating oil composition, whcih comprises titanate-modified graphene oxide slurry and a lubricating oil; and (2) a method for preparing a lubricating oil composition, which involves dispersing titanate-modified graphene oxide slurry and the lubricating oil ultrasonically at a power of 200 to 500 watts for 5 to 10 minutes to obtain the lubricating oil composition.
