Organic-inorganic hybrid microcapsule as well as preparation method and application thereof
The invention discloses an organic-inorganic hybrid microcapsule as well as a preparation method and application thereof, and belongs to the technical field of microcapsule preparation and self-repairing materials. The microcapsule provided by the invention comprises a core material and a capsule wall encapsulating the core material, the core material is a concrete crack repairing agent, and the capsule wall is prepared by cross-linking polymerization of hydrophobic silicon dioxide and ethyl cellulose; the thickness of the capsule wall is within the range of 3-5 microns; and the diameter of the microcapsule is in a range of 50-300 microns. Hydrophobic silicon dioxide and ethyl cellulose are subjected to cross-linking polymerization to obtain a capsule wall with a compact three-dimensional structure, so that the strength of the microcapsule is improved. The obtained microcapsule has the properties of both organic materials and inorganic materials, has excellent thermal stability and storage stability, and is good in mechanical property, controllable in mechanical property, regular and spherical in appearance and sensitive to concrete cracks. When the microcapsule is applied to repairing of concrete cracks, the obtained microcapsule has high triggering efficiency and self-repairing efficiency, and damage to concrete members can be reduced.
本发明公开了一种有机无机杂化的微胶囊及其制备方法与应用，属于微胶囊制备与自修复材料技术领域。本发明提供的微胶囊包括：芯材料和包封芯材料的囊壁，芯材料为混凝土裂缝修复剂，囊壁由疏水性二氧化硅与乙基纤维素交联聚合制得；囊壁的厚度在3‑5μm范围内；微胶囊的直径在50‑300μm范围内。疏水性二氧化硅与乙基纤维素两者交联聚合得到致密的三维结构的囊壁，提高微胶囊的强度。所得微胶囊兼具有机材料和无机材料的性能，具有优良的热稳定性及储存稳定性，且力学性能良好，机械性能可控，外观规则呈球形，对混凝土裂缝敏感。将其应用于混凝土裂缝修复时，所得微胶囊具有高的触发效率和自修复效率，能够减小混凝土构件的损坏。
