Cement-based material with dual chloride ion erosion resistance and preparation method thereof
The invention belongs to the field of corrosion protection, and relates to a cement-based material with dual chloride ion corrosion resistance and a preparation method thereof, the cement-based material is composed of polyethylene glycol molecular chain difunctional carbon dots, mixing water and Portland cement; the preparation method comprises the following steps: uniformly stirring polyethylene glycol and citric acid in deionized water, heating a citric acid/polyethylene glycol mixed solution for 4-8 hours at 160-180 DEG C by adopting a hydrothermal method, cooling, purifying and drying to obtain the polyethylene glycol molecular chain difunctional carbon dots; dissolving the polyethylene glycol molecular chain difunctional carbon dots in mixing water to obtain a polyethylene glycol molecular chain difunctional carbon dot solution; and adding the polyethylene glycol molecular chain difunctional carbon dot solution into Portland cement, and stirring to obtain the cement-based material with dual chloride ion erosion resistance. The raw materials are easy to obtain, preparation is simple, the problems that a traditional chloride ion erosion resistant material is single in action mechanism and limited in erosion resistance can be solved, and the corrosion resistance of the concrete reinforcement is remarkably improved.
本发明属于腐蚀防护领域，涉及一种具有双重抗氯离子侵蚀的水泥基材料及其制备方法，由聚乙二醇分子链双功能碳点、拌合水和硅酸盐水泥组成；制备步骤为：将聚乙二醇和柠檬酸在去离子水中搅拌均匀，采用水热法将柠檬酸/聚乙二醇混合溶液在160～180℃下加热4～8h，冷却后进行纯化和干燥，得到聚乙二醇分子链双功能碳点；将聚乙二醇分子链双功能碳点溶解在拌合水中，得到聚乙二醇分子链双功能碳点溶液；将聚乙二醇分子链双功能碳点溶液加入硅酸盐水泥中，搅拌，得到具有双重抗氯离子侵蚀的水泥基材料。本发明原料易得，制备简单，能够克服传统抗氯离子侵蚀材料作用机理单一、抗侵蚀性能有限的问题，显著提高混凝土钢筋抗腐蚀性能。
