▎ 摘  要

NOVELTY - Composite aluminum-based lubricating grease comprises 40-85 pts. wt. base oil, 5-15 pts. wt. thickener, 0.2-10 pts. wt. graphene, and 0.1-0.3 pts. wt. oil-soluble nano cerium oxide, where the thickener is composite aluminum-based thickener. USE - Used as composite aluminum-based lubricating grease. ADVANTAGE - The composite aluminum-based lubricating grease has good quality stability, excellent conductivity, high temperature resistance, colloid stability, mechanical stability, chemical stability, antiwear performance, water resistance and other comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite aluminum-based lubricating grease, comprising mixing graphene, 1/3-2/3 base oil, stearic acid, benzoic acid or terephthalic acid, aluminum isopropoxide tripolymer, heating to 80-100°C, carrying out saponification reaction, heating, refining at high temperature, adding the remaining base oil, then adding oil-soluble nano cerium oxide, and post-processing.
