The antirust oil is prepared from the following ingredients in parts by weight: 5 to 15 parts of oxidized petroleum wax salt, 0 to 5 parts of synthesized ammonium sulfonate and 35 to 90 parts of hydrorefined mineral oil, wherein the oxidized petroleum wax salt is at least one of calcium salt of oxidized petroleum wax, sodium salt of the oxidized petroleum wax or ammonium salt of the oxidized petroleum wax, and the base number of the oxidized petroleum wax salt is 100 to 500 mgKOH / g; the hydrorefined mineral oil is at least one of refined mineral oil with the viscosity of 5 mm<2> / s under 40 DEG C, refined mineral oil with the viscosity of 32 mm<2> / s under 40 DEG C or refined mineral oil with the viscosity of 68 mm<2> / s under 40 DEG C. The antirust oil disclosed by the invention has good environmental protection property and in the meantime, has a reasonable resistance value; the resistance value is only 0.1 to 20 M omega under the temperature of 20 to 60 DEG C; the antirust oil is suitable for electrostatic atomization spraying of metal, can form an even oil film on the plate surface, which cannot be broken down to generate electric spark to be combusted, and has high use safety; furthermore, the antirust performance is excellent, lowtemperature resistance of the product is good, and good fluidity can be achieved under the -20 DEG C environment.
