Intelligent release targeted migration type steel bar corrosion inhibitor
The invention discloses an intelligent release targeted migration type steel bar corrosion inhibitor, which is made into emulsion, microemulsion or nano-scale aqueous dispersion by using a corrosion inhibition component, a sealing component and a catalytic component. When the intelligent release targeted migration type steel bar corrosion inhibitor is brushed on the surface of concrete, the sealing component forms a film on the surface of the concrete, and the corrosion inhibition component has low surface tension, can rapidly permeate into the concrete through capillary pores of the concrete and then reaches the surface of a steel bar in the modes of concentration gradient, gas phase diffusion and the like, so that a compact adsorption film is formed on the metal surface, and the rust inhibition effect is achieved.
本发明公开了一种智能释放靶向迁移型钢筋阻锈剂，所述智能释放靶向迁移型钢筋阻锈剂使用阻锈组分、封闭组分及催化组分，制成乳液、微乳液或纳米级水分散液。涂刷智能释放靶向迁移型钢筋阻锈剂于混凝土表面时，封闭组分在混凝土表面成膜，阻锈组分具有较低的表面张力，能够通过混凝土毛细孔隙快速渗透至混凝土内部，再通过浓度梯度及气相扩散等方式到达钢筋表面，在金属表面形成致密吸附膜，从而起到阻锈作用。
