Abstract

The invention provides salt-spray-resistant anti-rusting oil containing an organic amine-carboxylate compound, as well as a preparation method and application of the anti-rusting oil. The anti-rusting oil provided by the invention has the advantages of being high in salt spray resistance and damp heat resistance, being friendly to the environment and preventing pollution. 15# machine oil and solvent oil are taken as a solvent, and the prepared organic amine-carboxylate compound and three other common anti-rusting agents in the market are added, so that the anti-rusting oil has a long rust-proof life on metal products, particularly has a long protection period on easily corrosive powder metallurgy ferrous metals. The anti-rusting oil disclosed by the invention is clear and transparent in appearance, does not have any precipitate, has high adhesive force on the metal surface and does not influence the appearance of the metal products. Moreover, the preparation method disclosed by the invention is simple, easy to operate, low in cost and suitable for large-scale production.

Description

[0001] Technical field: [0002] The invention relates to a salt spray antirust oil containing an organic amine-carboxylate compound and a preparation method thereof, belonging to the technical field of metal antirust. [0003] Background technique: [0004] Metal products will be affected by various environmental factors during processing, storage, transportation and use, resulting in varying degrees of corrosion. According to reports, the metal materials scrapped due to corrosion account for about 1 / 10 of the total metal production in the world every year, and the amount of steel that cannot be recycled due to corrosion in my country reaches more than 10 million tons every year. Not only that, metal corrosion can also cause indirect hazards such as material leakage, environmental pollution, shutdown and production reduction. Therefore, it is an important research topic to study the anti-corrosion technology of metal materials. [0005] The protection method of using anti-ru...
