Targeted corrosion inhibitor for marine reinforced concrete as well as preparation method and application of targeted corrosion inhibitor
The invention belongs to the technical field of building materials, and particularly relates to a targeted corrosion inhibitor for marine reinforced concrete as well as a preparation method and application of the targeted corrosion inhibitor. The targeted corrosion inhibitor for the marine reinforced concrete is a nitrite intercalated calcium-aluminum layered double-metal hydroxide of which the surface is loaded with silver ions. The targeted corrosion inhibitor is prepared on the basis of the interlaminar ion exchangeable characteristic of layered double hydroxides and the characteristic that silver ions specifically recognize chloride ions, nitrite with the corrosion inhibition effect can be released while intrusive chloride ions are cured in a targeted mode, a dual protection effect on reinforcing steel bars is achieved, and the targeted corrosion inhibitor is isomeric with cement hydration products, has no side effect on a concrete matrix, and has excellent anti-corrosion performance.
本发明属于建筑材料技术领域，具体涉及一种海工钢筋混凝土靶向阻锈剂及其制备方法和应用，本发明的海工钢筋混凝土靶向阻锈剂为表面负载银离子的插层亚硝酸根的钙铝型层状双金属氢氧化物，该靶向阻锈剂基于层状双金属氢氧化物的层间离子可交换特性及银离子特异性识别氯离子的特性制备得到，在靶向固化渗透侵入的氯离子的同时可以释放出具有阻锈作用的亚硝酸根，对钢筋达到一种双重保护的作用，且与水泥水化产物同质异构，对混凝土基体无副作用，防腐性能优异。
