PURPOSE:To obtain the oil composition having excellent corrosion prevention by mixing a mineral oil-based solvent having specific kinetic viscosity and a refined mineral oil-containing based oil with an alkaline earth metal sulfonate, an oxidized wax Ba salt, a lanolin fatty acid ester and a benzotriazole. CONSTITUTION:100 pts.wt. of a mineral oil-based solvent (e.g. paraffinic mineral oil-based solvent) having 1-3mm<2>/s kinetic viscosity at 40 deg.C is mixed with 20-40 pts.wt. fo a refined oil (e.g. paraffinic refined mineral oil) having 10-40mm<2>/s kinetic viscosity at 40 deg.C to give a mixed oil as a base oil. The mixed oil is blended, based on the total of a composition, with (A) 5-25wt.% of an alkaline earth metal sulfonate (e.g. neutral barium dinonylnaphthalenesulfonate), (B) 1-15wt.% of an oxidized wax Ba salt (e.g. oxidized paraffin barium salt), (C) 3-15wt.% of a lanolin fatty acid ester and (D) 0.01-5wt.% of a benzotriazole (derivative) to give the anti-corrosive oil composition. |
