Corrosion inhibitor doped in reinforced concrete and preparation method and application thereof
The invention discloses a corrosion inhibitor doped in reinforced concrete and a preparation method and application thereof. The corrosion inhibitor mainly comprises the following raw materials in percentage by mass: 15-30% of dimethylethanolamine, 5-10% of diethylenetriamine, 20-30% of lithium silicate, 5-10% of sodium gluconate and 20-55% of water. The corrosion inhibitor prepared by the method is an internal doping type reinforced concrete corrosion inhibitor, can obviously relieve the damage of chloride ions to a reinforcing steel bar passivation film, has the advantages of low doping amount, good adaptability to concrete and the like, is an efficient concrete reinforcing steel bar corrosion inhibitor, and can be used for reinforced concrete structures such as water conservancy, hydropower, ports, wharfs and the like. The corrosion inhibitor doped in the reinforced concrete prepared by the method is wide in raw material source, simple to prepare, simple, convenient and economical in construction, can be used for repairing and protecting a reinforced concrete structure, does not reduce the mechanical property of the concrete, protects reinforcing steel bars in the concrete for a long time, prolongs the service life of the reinforcing steel bars, and is economical and long-acting.
本发明公开了一种钢筋混凝土内掺缓蚀剂及其制备方法和应用，缓蚀剂主要包括以下质量百分比的原料：二甲基乙醇胺15‑30％、二乙烯三胺5‑10％、硅酸锂20‑30％、葡萄糖酸钠5‑10％、水20‑55％。本发明制备的缓蚀剂为内掺型钢筋混凝土缓蚀剂，能显著缓解氯离子对钢筋钝化膜的破化，具有掺量低、与混凝土适应性好等优点，是一种高效混凝土钢筋缓蚀剂，可用于水利、水电、港口码头等钢筋混凝土结构。本发明制备的钢筋混凝土内掺缓蚀剂，原料来源广，制备简单，施工简便经济，能用于钢筋混凝土结构修复和保护，不降低混凝土力学性能，长期保护混凝土中的钢筋，延长钢筋使用寿命经济长效。
