Environment-friendly composite steel bar corrosion inhibitor for marine environment and preparation method of corrosion inhibitor
The invention relates to an environment-friendly composite reinforcing steel bar corrosion inhibitor for a marine environment and a preparation method of the corrosion inhibitor, and belongs to the technical field of material science and engineering. The reinforcing steel bar corrosion inhibitor is prepared by compounding the following components in parts by mass: 0.15-0.35 part of molybdate, 0.1-0.65 part of benzotriazole and 100 parts of water. The preparation method comprises the following steps: firstly, weighing the molybdate and the benzotriazole in parts by mass, adding the molybdate and the benzotriazole into an alkaline solution with the pH value of 13.5 at room temperature, and uniformly stirring by using a glass rod. According to the invention, molybdate and benzotriazole which are harmless to the natural environment are compounded, so that harm of harmful corrosion inhibitors to the environment is reduced, and the composite corrosion inhibitor is green and environment-friendly. The molybdate and the benzotriazole are compounded to generate a synergistic effect, so that the reinforcing steel bar forms a layer of adsorption film in a marine environment, the film is high in compactness, can effectively prevent harmful ions from eroding the surface of the reinforcing steel bar and has a relatively good rust inhibition effect, and the preparation method is simple, economical in cost and convenient for industrial production.
本发明涉及一种用于海洋环境的环保型复合钢筋阻锈剂及其制备方法，属于材料科学与工程技术领域，该钢筋阻锈剂由钼酸盐和苯并三唑复配而成，各组分所占质量份数为钼酸盐0.15～0.35份，苯并三唑0.1～0.65份，水100份。制备步骤：先按质量份数称取钼酸盐和苯并三唑，在室温下加入pH为13.5的碱性溶液中用玻璃棒搅拌均匀，即配制完成。本发明将自然环境无害的钼酸盐和苯并三唑进行复配，降低了有害阻锈剂对环境的危害，是一种绿色环保的复合阻锈剂。钼酸盐与苯并三唑复配后发生了协同效应，使得钢筋在海洋环境中形成了一层吸附膜，该膜的致密度好，能有效的阻止有害离子对钢筋表面的侵蚀，具有较好的阻锈效果，本发明制备方法简单，成本经济，便于工业化生产。
