The invention belongs to the technical field of building material additives, and particularly relates to a concrete corrosion and rust inhibitor and a preparation method thereof. The corrosion and rust inhibitor comprises the following components in percentage by weight: 3 to 5 percent of kaolin, 2 to 3 percent of modified epoxy resin, 1 to 3 percent of silane coupling agent, 5 to 10 percent of nitrite, 2 to 4 percent of thiourea, 6 to 10 percent of triethanolamine, 7 to 10 percent of sodium dodecyl sulfate, 1 to 5 percent of sodium octyl sulfonate, 15 to 20 percent of shrinking agent and the balance of water. The preparation method comprises the following steps: weighing the kaolin, the modified epoxy resin, the silane coupling agent, nitrite, thiourea, triethanolamine, sodium dodecyl sulfate, sodium octylsulfonate, the shrinking agent and water in percentage by mass, carrying out ultrasonic treatment at room temperature, standing, and stirring to obtain the concrete corrosion and rust inhibitor. The concrete anti-corrosion and anti-rust agent prepared by the preparation method disclosed by the invention not only has a composite characteristic, but also remarkably improves the durability of concrete in various environments through a unique preparation process.
本申请属于建筑材料添加剂技术领域，具体涉及一种混凝土防腐阻锈剂及其制备方法。本申请的防腐阻锈剂包括如下重量百分比的组分：3～5wt.％高岭土、2～3wt.％改性环氧树脂、1～3wt.％硅烷偶联剂、5～10wt.％亚硝酸盐、2～4wt.％硫脲、6～10wt.％三乙醇胺、7～10wt.％十二烷基磺酸钠、1～5wt.％辛基磺酸钠、15～20wt.％缩水剂和余量的水。本申请制备方法为按质量百分比称取高岭土、改性环氧树脂、硅烷偶联剂、亚硝酸盐、硫脲、三乙醇胺、十二烷基磺酸钠、辛基磺酸钠、缩水剂和水，室温下超声处理，随后静置，再搅拌得到混凝土防腐阻锈剂。本申请制备的混凝土防腐阻锈剂，不仅具备复合型的特性，而且通过独特的制备工艺，显著提升了混凝土在多种环境下的耐久性。
