Multifunctional organic rust inhibitor and preparation method thereof
The invention relates to a multifunctional organic rust inhibitor prepared by reaction of an organic acid and a hydroxyl compound, the molar ratio of organic acid to hydroxyl compound is 1:1-1:2.5; the organic acid is an arbitrary proportion mixture of one or more than two substance of lauric acid, palmitic acid, stearic acid, benzoic acid, p-tert-butyl benzoic acid, lauroyl sarcosine and oleoyl sarcosine, the hydroxyl compound is an arbitrary proportion mixture of one or more than two substance of n-butyl alcohol, lauryl alcohol, ethanolamine, diethanolamine, triethanolamine, N-methyldiethanolamine, N, N-dimethylethanolamine, and 2-amino-2-methyl-1 - propanol. The multifunctional organic rust inhibitor can protect steel bar and concrete from erosion of chloride and sulfate and other corrosion mediums, plays a dual role of concrete self protection and steel bar corrosion protection, greatly improves the service life of a reinforced concrete structure, and is simple in synthesis process and easy to implement.
