Polymer capsule for mass concrete self-repairing and preparation method thereof
The invention belongs to the technical field of concrete self-repairing, and particularly relates to a polymer capsule for mass concrete self-repairing and a preparation method thereof. The polymer capsule is prepared from the following raw materials: a capsule core material, a capsule wall material a, a capsule wall material b, a solubilizer, a modifier, a cross-linking agent, a pH regulator, an organic solvent and a proper amount of deionized water. The polymer capsule disclosed by the invention can be added into mass concrete, and can be uniformly heated and timely broken in the early-stage mass concrete concentrated heat release cracking danger period, so that a capsule core material is released, and cracks generated by a matrix are repaired.
本发明属于混凝土自修复技术领域，具体涉及一种大体积混凝土自修复用聚合物胶囊及其制备方法。该聚合物胶囊所用原料为：囊芯材料、囊壁材料a、囊壁材料b、增溶剂，改性剂，交联剂、pH调节剂、有机溶剂及去离子水适量。本发明的聚合物胶囊可以添加到大体积混凝土中，在前期大体积混凝土集中放热的开裂危险期，聚合物胶囊能够受热均匀，及时破裂，从而使囊芯材料得到释放，对基体产生的裂缝进行修补。
