▎ 摘 要
NOVELTY - A grease composition comprises 80-92 wt.% base oil, 8-16 wt.% thickener, 1-4 wt.% tackifier, 1.5 wt.% antioxidant, 1 wt.% rust inhibitor, 0.02-0.2 wt.% graphene and 1-8 wt.% solid additives. USE - The grease composition is useful for suspender of washing machine. ADVANTAGE - The grease composition improves strength of suspender, and has improved water resistance, anticorrosive property and adhesiveness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of grease composition, which involves mixing base oil, thickener, tackifier, antioxidant, rust inhibitor, graphene and solid additives, heating at 80-85 degrees C in a reactor, saponifying at 95-100 degrees C, heating at 100-110 degrees C, adding water or alkali solution and then heating at 125-135 degrees C, melting at 205-215 degrees C and heating at 140-150 degrees C.
