Deep permeable crystallization self-healing waterproof material as well as preparation method and application thereof
The invention discloses a deep permeable crystallization self-healing waterproof material as well as a preparation method and application thereof. The waterproof material comprises a cement-based material component, an active component, a rehydration plugging component and a functional component. During use, the active component and the rehydration plugging component can migrate into the concrete and react with each other, the functional component can provide water for chemical reaction for the active component and the rehydration plugging component, and the active component, the rehydration plugging component and the functional component can react with each other and have a synergistic effect to generate a fibrous or dendritic hydration product, so that pores are effectively plugged, refined and sealed. Furthermore, part of the microcapsules can be penetrated by the cracks to release the core material, and the core material plays a role in blocking, blocking and filling the cracks or pores after being cured; part of the active components and the rehydration plugging components can be subjected to a rehydration reaction, so that the effects of enhancing the hardness of the concrete surface layer, improving the density of a microstructure, reducing the porosity and realizing crack self-healing are achieved, and the waterproof and durability performances of the concrete structure surface layer are effectively improved.
本发明公开了一种深度渗透结晶自愈型防水材料、制备方法及其应用，该防水材料包括水泥基材料组分、活性组分、再水化封堵组分以及功能组分。使用时，活性组分、再水化封堵组分可迁移进入混凝土内部，并且两组分相互反应，功能组分可为活性组分和再水化封堵组分提供化学反应的水分，三者相互反应和协同作用，可生成纤维状或树枝状水化产物，有效封堵、细化和封闭孔隙。再者，部分微胶囊会被裂缝贯通而释放出芯材，固化后起到封堵、阻断和填充裂缝或孔隙的作用；部分活性组分和再水化封堵组分可进行再次水化反应，起到强化混凝土表层硬度、提高微观结构致密度、减少孔隙率和裂缝自愈合的作用，从而有效提高混凝土结构表层防水和耐久性能。
