▎ 摘  要

NOVELTY - Graphene lubricating grease comprises 35-94.8% of lubricating base oil, 5-35% of thickening agent, 0.1-15% of graphene, and 0.1-15% of tetra-alkyltitanate modifier. USE - Graphene lubricating grease. ADVANTAGE - The graphene lubricating grease is good for batch industrial production, has synergistic effect and excellent performance, and improves anti-wear properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene lubricating grease, which involves: (A) adding base oil in lipid, adding organic acid and aqueous solution of alkali, raising temperature to 70-100 degrees C to perform saponification reaction; (B) continuously heating to 100-130 degrees C, and removing water; (C) subjecting to saponification, adding tetra-alkyl titanate modified agent and graphene, and mixing uniformly; and (D) continuously heating to 180-230 degrees C, carrying out high temperature refining, then cooling and homogenizing into fat.
