PURPOSE:The titled composition having improved anticorrosion properties, weather resistance, and water-vapor resistance, slightly being attached by strain, having improved removing properties of dust, etc. by waste clothes, etc., obtained by blending petroleum base oil and an oil-soluble organic rust preventive agent with a perfluoroalkyl-type surface active agent. CONSTITUTION:A rust preventive composition consisting of (A) petroleum base oil (e.g., gear oil, motor oil, illuminating kerosine, etc.) and (B) an oil-soluble organic rust preventive agent (e.g., Ba salt of petroleum sulfonate, etc.) is blended with (C) a perfluoroalkyl-type surface active agent (e.g., preferably having C>=8 perfluoroalkyl group such as perfluoroalkyl sulfonate, perfluoroalkyl phosphate, etc.), dissolved or dispersed uniformly, to give the desired composition. The blending amounts of the ingredients B and C are preferably not less than 0.2wt% (particularly preferably, 0.5-20wt%) and not less than 0.01wt% (particularly preferably, 0.05-1.0wt%) respectively based on ingredient A. |
