Embodiment 1

[0020] 1# Vapor-phase anti-rust oil, composed of the following components by weight:

[0021]

[0022]

[0023] Product preparation method and steps are as follows:

[0024] Raw material components in proportion: 91 parts of 500SN base oil, 5 parts of benzotriazole, tert-butyl chromate, naphthenic acid soap, mixture of sodium petroleum sulfonate, 1 part of calcium petroleum sulfonate, 1 part of benzene Sodium formate, 0.5 part of silicone defoamer, 1 part of thionyl zinc, 0.5 part of phenol.

[0025] Add sodium benzoate to the mixture of benzotriazole, tert-butyl chromate, naphthenic acid soap, and sodium petroleum sulfonate at a temperature lower than 120°C, and heat to dissolve. When benzotriazole, tert-chromic acid After the mixture of butyl ester, naphthenic acid soap and sodium petroleum sulfonate is completely melted, slowly add it into the reaction kettle, stir while adding, and then add calcium petroleum sulfonate, phenol, silicone defoamer and Thiophos-butyloc...

Abstract

The invention discloses volatile rust preventive oil which comprises, by weight, 71-91% of base oil, 5-25% of an oil soluble volatile corrosion inhibitor, 1-5% of an antirusting agent, 1-6% of a cosolvent, 0.5-1% of a mildew-proof agent, 0.5-1% of an antifoaming agent and 1-6% of antioxidant, wherein the base oil is one of 500SN 46# machine oil, 32# machine oil, 600SN 150# machine oil and 100# machine oil; and the oil soluble volatile corrosion inhibitor is a mixture of four kinds of 2-heptadecenyl-imidalidine, octadecylamine, triazole tributylamine, dicyclohexylamine carbonate, dicyclohexylaminenitrite, benzotriazole, tert-butyl chromate, nephthenic soap, petroleum sodium sulfonate, sorbitan monooleate and stearic acid; and the antioxidant is sulfurphosphorousbutyloctyl zinc salt. The volatile rust preventive oil has good volatile rust preventive and corrosion resistant performances, metal which cannot be coated with rust preventive oil can achieve rust preventive protection, the operation is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and relates to a gas phase antirust oil. Background technique [0002] Anti-rust oil plays an important role in metal corrosion. However, the existing anti-rust oil is composed of base oil and oil-soluble corrosion inhibitor, which can only play the function of contact anti-rust. For those parts that cannot contact anti-rust oil, such as special gears such as engines and compressors box, it cannot form an effective rust protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vapor phase anti-rust oil to solve the problem that the special gear boxes of some equipment (engines, compressors, etc.) are easy to oxidize and rust due to lack of contact with the anti-rust oil. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A gas phase antirust oil is characterized...
