Hybrid self-repairing microcapsule as well as preparation method and application thereof
The invention discloses a hybrid self-repairing microcapsule as well as a preparation method and an application thereof, a solvent evaporation method is adopted, epoxy resin is taken as a core material, ethyl cellulose is taken as a wall material, and a slow-release self-repairing microcapsule with slow-release repairing capability is prepared; an in-situ polymerization method is adopted, epoxy resin is used as a core material, urea resin is used as a wall material, a common self-repairing microcapsule with the fracture repairing capacity is prepared, the two microcapsules are mixed according to a certain proportion, and the mixed self-repairing microcapsule is obtained. The hybrid self-repairing microcapsule is good in microstructure and moderate in particle size distribution, complementary advantages of the two microcapsules can be achieved when the hybrid self-repairing microcapsule is doped into a cement matrix, the hybrid self-repairing microcapsule is applied to building pouring, rapid repairing and repeated repairing of the cement matrix can be achieved, and the self-repairing capacity of a composition is improved.
本发明公开了一种混杂自修复微胶囊及其制备方法和应用，采用溶剂蒸发法，以环氧树脂为芯材，乙基纤维素为壁材，制备具有缓释修复能力的缓释型自修复微胶囊；采用原位聚合法，以环氧树脂为芯材，脲醛树脂为壁材，制备具有破裂修复能力的普通型自修复微胶囊，将两种微胶囊通过一定比例的混杂，得到混杂自修复微胶囊；该混杂自修复微胶囊微观形貌良好，粒度分布适中，掺入水泥基体可以实现两种微胶囊的优势互补，将其应用于建筑浇注，可实现水泥基体的快速修复及多次修复，提高组合物的自修复能力。
