Surface application composite migration corrosion inhibitor and preparation method thereof
The invention relates to the technical field of building materials, in particular to a surface application composite migration corrosion inhibitor and a preparation method thereof. The surface application composite migration corrosion inhibitor comprises an organic component, an inorganic component and water, the organic component is formed by compounding diethanolisopropanolamine and alkylol amine Nn, the inorganic component is nitrite, and n is a natural number. The corrosion inhibitor can be used for corrosion media chloride ions and sulfate ions at the same time, and the defects that a traditional corrosion inhibitor is large in dosage, low in efficiency and single in effect are overcome. The triethanolamine and other alcohol amine components make up the risk of accelerated corrosion caused by insufficient mixing amount of sodium nitrite, and sodium nitrite makes up the possibility of corrosion inhibitor failure after the organic components are degraded under concrete or corresponding alkaline conditions. The organic component and the inorganic component are used together, and the double protection effect is achieved for the steel bar corrosion problem. The surface application composite migration corrosion inhibitor serves as an external component and can perform corrosion protection on an existing reinforced concrete structure in an external coating mode.
本发明涉及建筑材料技术领域，具体涉及一种表面应用复合型迁移阻锈剂及其制备方法，包括有机组分、无机组分和水，其中，有机组分由二乙醇单异丙醇胺、醇胺Nn复合而成，所述无机组分为亚硝酸盐，其中n为自然数。本发明阻锈剂可同时针对腐蚀介质氯离子与硫酸根离子，打破传统阻锈剂用量大、效率低、作用单一的困局。三乙醇胺等醇胺组分弥补了亚硝酸钠掺量不足所引起的加速腐蚀风险，同时亚硝酸钠又弥补了有机组分在混凝土或相应碱性条件下有机组分降解后缓蚀剂失效的可能，本发明中有机组分与无机组分联合使用，对钢筋锈蚀问题起到双重防护功效。本发明表面应用复合型迁移阻锈剂作为外加成份通过外涂形式可对已有的钢筋混凝土结构进行腐蚀防护。
