NOVELTY - The lubricating grease composition comprises 65-95 wt.% lubricating base oil, 6-20 wt.% lithium base thickening agent, and 0.5-15 wt.% graphene. USE - Lubricating grease composition. ADVANTAGE - The lubricating grease composition ensures excellent temperature resistance, water and adhesion resistance, colloid stability, extreme pressure abrasion resistance, corrosion resistance and anti-salt fog character. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lubricating grease composition, which involves: (A) mixing lubricating base oil, graphene and lithium base thickening agent at 80-105 degrees C; (B) adding lithium hydroxide and water for carrying out saponification reaction at 190-220 degrees C; (C) adding the rest base oil at 100-120 degrees C; and (D) adding necessary additives for grinding to form the product.
