Slow-seepage-resistant waterproof plugging mortar and preparation method thereof
The invention discloses slow-seepage-resistant waterproof leaking stoppage mortar and a preparation method thereof. The formula and the manufacturing process of the mortar are reasonable in design and convenient to use; cement, sand and mineral admixtures serve as composite gel components, and a water-borne epoxy resin emulsion and a water-borne epoxy curing agent can adjust the setting time of the mortar, so the strength, anti-permeability and other properties of the mortar are improved, and the mortar has good waterproof and anti-permeability properties; and in addition, a super absorbent polymer is wrapped by a water-soluble polymer to form a microcapsule, the super absorbent polymer does not participate in a reaction during stirring, mixing and cement solidification in virtue of the characteristic of slow dissolution of the water-soluble polymer, but the surface of the microcapsule is dissolved when mortar cracks and water flows into the microcapsule, so the water-absorbent polymer can quickly block cracks by utilizing the water absorption expansibility of the water-absorbent polymer, and a certain leakage self-repairing function is obtained.
本发明公开了一种抗慢渗防水堵漏砂浆及其制备方法，本发明配方及制作工艺设计合理，使用方便，本发明通过水泥、砂及矿物掺合料作为复合凝胶组分，所述水性环氧树脂乳液、水性环氧固化剂可调节砂浆的凝结时间，提高砂浆强度、抗渗等性能，具有良好的防水、抗渗性能；此外本发明通过水溶性聚合物包裹高吸水性聚合物，形成微胶囊，利用水溶性聚合物溶解缓慢的特性使高吸水性聚合物在搅拌混合和水泥固化时不参与反应，但砂浆开裂有水流入时，所述微胶囊表面溶解，所述吸水性聚合物利用自身吸水膨胀性可快速堵塞裂缝，具有一定的渗漏自修复功能。
