Description

technical field

[0001] The invention belongs to the field of iron and steel rust prevention, in particular relates to an antirust agent and a preparation method thereof, and more particularly relates to a long-acting water-based antirust agent and a preparation method thereof. Background technique

[0002] During the storage and transportation of steel materials, cast iron, mechanical parts, and alloy steel products, if they are not treated with anti-rust treatment, rust will occur in a short period of time, which will have a negative impact on the appearance and performance of finished steel and precision parts, and the corrosion will be serious It may even cause the steel to be scrapped, the parts cannot be used, and cause great economic losses. Therefore, the research on antirust liquid plays an important role in the protection of steel materials. Most of the metal water-based anti-rust liquids used in the past contain sodium nitrite. Nitrite-based water-based anti-rust l...
