PURPOSE:To provide a grease composition which develops good rustproofness even under severe conditions by compounding a grease composition with an oil-soluble organic inhibitor, a water-soluble inorganic inactivator and a nonionic surfactant. CONSTITUTION:A rustproof grease composition comprises a grease composition (i) and 0.1-10wt.% each of oil-soluble organic inhibitors (e.g. Ba, Ca and Zn salts of sulfonic acids such as petroleum sulfonic acid or dinonylnaphthalenesulfonic acid), water-insoluble inorganic inactivators (e.g. chromic acid salts, nitrous acid salts or molybdic acid salts) and nonionic surfactants (HLB: 1.5-9, e.g. sorbitan trioleate) as rust-preventing additives. component (i) comprises base oil such as alkyldiphenyl ether and a thickner (e.g. a dirurea compound comprising tolylene diisocyanate and p-toluidine). |
