Organic-inorganic composite ternary microsphere capable of realizing self-riveting in cement matrix as well as preparation and application of organic-inorganic composite ternary microsphere
The invention relates to the technical field of building materials, in particular to an organic-inorganic composite ternary microsphere capable of achieving self-riveting in a cement matrix and preparation and application of the organic-inorganic composite ternary microsphere. The microsphere comprises a microcapsule body with a repairing agent as a core and a semi-interpenetrating network hydrogel material as a shell; a pozzolanic material is embedded in the surface of the shell and is used for performing pozzolanic reaction with a cement matrix to realize riveting of the shell and the cement matrix. The preparation method comprises the following steps: premixing a pozzolanic material and water to obtain a turbid liquid; adding a semi-interpenetrating network hydrogel pre-polymer into the turbid liquid, and mixing to obtain a first mixture; mixing the first mixture, a repairing agent and an emulsifying agent to obtain a second mixture; the second mixture is subjected to cross-linking, curing and forming through a sharp hole-coagulating bath method, and the microspheres are obtained. The microspheres and a cement matrix can successfully construct a self-riveting structure, and the problems that the interface bonding is poor and the self-repairing efficiency needs to be improved due to the fact that water-absorbing microcapsules serve as hydrogel of a shell are solved.
本发明涉及建筑材料技术领域，尤其涉及一种在水泥基体中可实现自铆接的有机无机复合三元微球及其制备和应用，该微球包括：以修复剂为核和以半互穿网络水凝胶材料为壳的微胶囊本体；所述壳表面镶嵌火山灰质材料，所述火山灰质材料用于与水泥基体发生火山灰反应实现二者的铆接。该制备方法包括：将火山灰质材料和水预混得到悬浊液；将半互穿网络水凝胶前聚物加入所述悬浊液中混合得到所述第一混合物；将所述第一混合物、修复剂和乳化剂混合得到第二混合物；将所述第二混合物采用锐孔‑凝固浴法交联固化成型，得到微球。本发明的微球能与水泥基体成功构筑出自铆接结构，解决因吸水性微胶囊作为壳的水凝胶造成的界面结合差、自修复效率待提升的问题。
