Self-driven migration type corrosion inhibitor and preparation method thereof
The invention discloses a self-driven migration type corrosion inhibitor and a preparation method thereof, and belongs to the technical field of concrete admixtures. The corrosion inhibitor comprises the following raw materials in percentage by mass: 1-10% of a self-driven catalytic component, 20-35% of a permeation component, 15-30% of a corrosion inhibition component, 1-8% of an additive and the balance of water, the self-driven catalytic component has a core-shell structure, a Bi-TiO2 photocatalyst is taken as a core, and siliceous gel is taken as a shell; the siliceous gel is prepared by carrying out acid-base amphoteric treatment on a silicon source. The self-driven catalytic component provided by the invention can excite electron transition to generate energy by capturing light energy, and the generated energy can be converted into power for driving the corrosion inhibition component to move inwards, so that the infiltration capacity of effective components in the corrosion inhibitor is improved, and the action depth of the corrosion inhibition component in a concrete structure system is increased; and the concentration of the anti-rust component acting on the surface of the reinforcing steel bar is increased, so that the corrosion rate of the reinforcing steel bar is obviously reduced.
本发明公开一种自驱动迁移型阻锈剂及其制备方法，属于混凝土外加剂技术领域。其原料包括以下质量百分比的各组分：自驱动催化组分1～10％，渗透组分20～35％，阻锈组分15～30％，外加剂1～8％，余量为水；所述自驱动催化组分具有核壳结构，以Bi‑TiO2光触媒为核，以硅质凝胶为壳；所述硅质凝胶由硅源经过酸碱两性处理后制得。本发明的自驱动催化组分可以通过捕捉光能激发电子跃迁产生能量，产生的能量可以转化为驱动阻锈组分内迁的动力，提升阻锈剂中的有效组分的渗透能力，增加阻锈组分在混凝土结构体系中的作用深度；并增加作用于钢筋表面的阻锈组分的浓度，显著降低钢筋的锈蚀率。
