▎ 摘　　要

NOVELTY - A lubricant composition comprises 0.01-0.03 pts. wt. polymer modified load transition metal complex graphene or graphene oxide, 5-15 pts. wt. organic matter dispersant, and 0.2-0.4 pts. wt. sulfonate. USE - Lubricant composition used for lubricating oil. ADVANTAGE - The lubricant composition solves easy precipitation and poor dispersion problems in lubricating oil, does not contain potentially harmful elements and components, and has fuel saving and emission reduction effects, good solubility and dispersion capability, improved lubricating properties, reduced friction coefficient, increased wear resistance, and good extreme pressure performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of lubricant composition comprising: (A) high-speed ball milling graphene or graphene oxide with environment-friendly type solvent, taking out, statically separating to obtain suspension solution and solid precipitate; (B) adding transition metal complex into suspension solution, vacuum-drying to 80-100 degrees C, adding halogenated hydrocarbon as initiator, and polymerizing to 100-150 degrees C in the presence of styrene and methacrylate copolymer; and (C) cooling to 80-90 degrees C, adding organic matter dispersant and sulfonate, and mixing.
