Corrosion inhibitor for steel wire and preparation method thereof

Abstract

The invention provides a corrosion inhibitor for a steel wire. The corrosion inhibitor comprises the following components in parts by weight: 20-50 parts of polyvinyl alcohol, 30-70 parts of polyethylene glycol, 2-7 parts of ammonium benzoate, 3-6 parts of trisodium phosphate, 1-5 parts of thiocarbamide, 2-8 parts of sodium thiosulfate, 1-5 parts of triethanolamine, 1-6 parts of undecanedioic acid, 1-4 parts of benzotriazole, 3-9 parts of citric acid, 1-4 parts of sodium molybdate, 3-7 parts of tetrapropyl ammonium acetate and 100-300 parts of water. The preparation method disclosed by the invention comprises the following steps: adding polyvinyl alcohol and polyethylene glycol to water, and heating while stirring, so as to completely dissolve polyvinyl alcohol and polyethylene glycol; then adding other components, and stirring at 40-60 DEG C in a heat-preservation manner; cooling to room temperature after completely dissolving. The corrosion inhibitor for the steel wire disclosed by the invention has the characteristics of being long in anti-rust time, good in anti-corrosion performance, low in cost, environment-friendly and the like.

Description

technical field

[0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a steel wire antirust agent and a preparation method thereof. Background technique

[0002] Steel wire is widely used in bridges, automobiles, electronics, power transmission and other industries. When preparing steel wire products, cleaning and antirust treatment of the material before processing is an important process in the production process. For high-tech products, the cleaning of steel wire materials And anti-rust treatment is the key process. The cleanliness and anti-rust treatment of steel wire materials are related to the performance, quality, service life and reliability of the product. Anti-rust treatment is very sensitive, and tiny pollution and rust spots will have a serious impact on product performance, quality, service life and reliability. Therefore, improving the cleanliness and antirust treatment effect of steel wire materials has...
