Abstract

The invention discloses a steel product corrosion inhibitor. The steel product corrosion inhibitor comprises the following raw materials in parts by mass: 6-8 parts of sodium tungstate, 7-11 parts of calcium gluconate, 3-5 parts of mercaptobenzothiazole, 4-6 parts of alkyl amino-alcohol, 10-12 parts of imidazoline, 3-4 parts of 1-Hydroxyethylidene-1,1-diphosphonic acid, 6-9 parts of sodium molybdate, 4-8 parts of sodium dodecylbenzene sulfonate, 5-7 parts of polyaspartic acid and 5-8 parts of glycol. The steel product corrosion inhibitor has good economic efficiency, strong environmental responsibility and strong applicability, is wide in application scope, reduces the cost of maintenance and operation and can form oil films on surfaces of steel products to prevent corrosion.

Description

technical field [0001] The invention relates to the technical field of corrosion inhibitors, in particular to a steel corrosion inhibitor. Background technique [0002] During the storage of steel, due to the combination of water vapor and oxygen in the air and corrosive substances, the surface of the steel will be eroded, causing corrosive spots on the surface of the steel, resulting in defects in usability and aesthetics, affecting the sales of steel products, and increasing The cost of maintaining and operating the above. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a steel corrosion inhibitor with good economy, strong environmental protection ability, strong applicability and wide application range, which can form an oil film on the surface of steel to prevent corrosion. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a steel corrosi...
