In-situ curing microcapsule for self-repairing of concrete, preparation method of in-situ curing microcapsule and self-repairing concrete
The invention discloses an in-situ curing microcapsule for concrete self-repairing, a preparation method of the in-situ curing microcapsule and self-repairing concrete.The in-situ curing microcapsule for concrete self-repairing comprises a composite capsule wall composed of an inner wall and an outer wall; a curing agent is loaded in the outer wall, and the curing agent is attached to the outer wall; the inner wall does not contain a curing agent; the composite capsule wall is filled with a repairing agent, the repairing agent and the curing agent are separated through the inner wall, and when the composite capsule wall is damaged, the repairing agent and the curing agent are combined in situ; the problems that an adhesive is not completely cured and concrete cracks cannot be effectively repaired due to the fact that the adhesive and a curing agent of an existing self-repairing microcapsule cannot be fully contacted are effectively solved. In addition, after the self-repairing concrete provided by the invention finishes self-repairing of concrete micro-cracks, the mechanical properties such as compressive strength, breaking strength and the like of the self-repairing concrete can be further improved.
本申请公开了一种混凝土自修复用原位固化微胶囊及其制备方法、自修复混凝土，所述混凝土自修复用原位固化微胶囊，包括由内壁和外壁组成的复合囊壁；所述外壁的壁内负载有固化剂、壁外附着所述固化剂；所述内壁不含固化剂；所述复合囊壁内装有修复剂，所述修复剂与所述固化剂通过所述内壁隔开，所述复合囊壁破损，所述修复剂与所述固化剂原位结合；有效解决现有自修复微胶囊由于粘合剂与固化剂无法充分接触，导致粘合剂固化不完全，无法有效修复混凝土裂缝的问题；另外，本发明的自修复混凝土，在自修复完混凝土微裂缝后，还可以进一步提高其抗压强度和抗折强度等力学性能。
