Geopolymer self-repairing microcapsule as well as preparation method and application thereof
The invention belongs to the technical field of concrete crack repairing materials, particularly relates to a geopolymer self-repairing microcapsule, and also relates to a preparation method and application of the geopolymer self-repairing microcapsule. The geopolymer self-repairing microcapsule is prepared from the following raw materials: acrylic acid, sodium hydroxide, zeolite, an initiator, a cross-linking agent, a capsule wall material, an emulsifier, an organic solvent and a dispersing agent. When cracks exist, the super absorbent resin can release water, the cracks in the geopolymer continue to be hydrated, the cracks are repaired, interface bonding is tighter through the repairing mode, and the interfaces are not prone to cracking when bearing loads again.
本发明属于混凝土裂缝修复材料技术领域，具体涉及一种地聚合物自修复微胶囊，同时还涉及该地聚合物自修复微胶囊的制备方法和应用。地聚合物自修复微胶囊所用的原料有丙烯酸、氢氧化钠、沸石、引发剂、交联剂、囊壁材料、乳化剂、有机溶剂、分散剂。当裂缝存在时，高吸水性树脂会释放水，使地聚合物中的裂缝继续水化，将裂缝修复，这种修复方式使界面结合更加紧密，再次承受载荷时界面处不易开裂。
