Graphene loaded amino-triazole corrosion inhibitor containing chlorobenzaldehyde active group and application thereof

Abstract

The invention relates to corrosion inhibitors, in particular to a graphene loaded amino-triazole corrosion inhibitor containing a chlorobenzaldehyde active group and application thereof. The graphene loaded amino-triazole corrosion inhibitor compound is formed by chemical loading of chlorobenzaldehyde-[5-p-methylphenyl-1-amino-(1,3,4-triazoles)-2-mercapto]-acetyl hydrazones at active sites of oxygen containing functional groups of the graphene molecular layer. The compound is applied to the concrete alkaline environment or the corresponding alkaline condition, and through a cathodic oxygen reduction reaction in the electrochemical process of acting of the graphene molecular layer catalyzed and loaded corrosion inhibitor and carbon steel, a carbon steel material in a seawater or a sodium chloride medium and a steel bar product of the carbon steel material are subjected to corrosion protection. The corrosion inhibitor is wide in source, easy to mass-produce, extremely less in using amount, efficient in performance, high in sustained action capability and capable of effectively inhibiting corrosion destruction of the carbon steel and has significant application value and wide market prospects.

Description

technical field [0001] The invention relates to a rust inhibitor, in particular to a graphene-loaded aminotriazole rust inhibitor containing chlorobenzaldehyde active groups and an application thereof. Background technique [0002] Reinforced concrete is the main material of coastal and offshore engineering construction. Under the marine corrosion environment, the corrosion of steel bars caused by the penetration of high-concentration chloride ions is the primary factor leading to the deterioration of concrete structures. There are many ways to isolate chloride ion corrosion, steel rust inhibitor is the most simple, economical and efficient anti-corrosion technology. [0003] At present, the focus of research and application of steel corrosion inhibitors is the organic migratory corrosion inhibitor (MCI), which can be used as a concrete additive for new construction, and can also be applied to in-service structures. Deep protection, however, looking at the mushrooming acade...

Problems solved by technology

[0003] At present, the focus of research and application of steel corrosion inhibitors is the organic migratory corrosion inhibitor (MCI), which can be used as a concrete additive for new construction, and can also be applied to in-service structures. Deep protection, however, looking at the mushrooming academic reports and market products, there is still no scientific and technological achievement comparable to the protection efficiency of the mixed-type nitrite steel passivator.
