Reinforcing steel bar corrosion-resistant coating material, preparation method thereof, and reinforcing steel bar corrosion-resistant method
The invention discloses a steel bar corrosion-resistant coating material, a preparation method thereof, and a steel bar corrosion-resistant method. The steel bar corrosion-resistant coating material is mainly suitable for rust and corrosion resistance of reinforced concrete in a saline-alkali environment, and the steel bar corrosion-resistant coating material comprises Portland slag cement, water-borne epoxy resin, an emulsion type interface treating agent, a steel bar corrosion inhibitor and a defoaming agent in a mass ratio of (50-70): (10-20): (10-20): (5-10): (0.1-0.5). The used emulsion type interface treating agent and the steel bar corrosion inhibitor are optimized, so that a corrosion-resistant coating obtains excellent rust-resistant and corrosion-resistant performance, meanwhile, the bond stress of steel bars and concrete is improved, the problems of corrosion, spalling and the like of the steel bars caused by chloride ion erosion in the service process of reinforced concrete in a saline-alkali environment are solved, the corrosion resistance of steel bars in reinforced concrete can be obviously improved, the concrete is prevented from bulging and spalling due to corrosion of the steel bars, the service life of a building in a saline-alkali environment is prolonged, and the later maintenance cost is reduced.
本发明公开了一种钢筋阻锈涂层材料及其制备方法和钢筋阻锈方法，该钢筋阻锈涂层主要适用于盐碱环境中钢筋混凝土的阻锈防蚀，其各组分的质量比为矿渣硅酸盐水泥：水性环氧树脂：乳液型界面处理剂：钢筋阻锈剂：消泡剂=50‑70：10‑20：10‑20：5‑10：0.1‑0.5。通过对使用的乳液型界面处理剂和钢筋阻锈剂进行了优化，使得阻锈涂层在获得优异阻锈防蚀性能的同时，提高钢筋与混凝土的握裹力，解决了盐碱环境中钢筋混凝土在服役过程中因受氯离子侵蚀引起的钢筋锈蚀、胀裂等问题，可明显提升钢筋混凝土中钢筋耐锈蚀性能，防止混凝土因钢筋锈蚀发生鼓包、胀裂，增加盐碱环境中建筑物使用寿命，减少后期维修成本。
