Cement-based material for rapid sealing repair as well as preparation method and application of cement-based material
The invention discloses a cement-based material for rapid sealing and repairing and a preparation method and application thereof.The cement-based material comprises hydrogel monomer microspheres and cross-linking agent microspheres, the two microspheres are both of core-shell structures, the inner core is a hydrogel monomer or a cross-linking agent, the outer shell is cement, a layer of hydrophobic organic film is attached to the surface of each microsphere, and the hydrophobic organic film is coated on the surface of each microsphere. The preparation method comprises the following steps: (1) respectively adding a hydrogel monomer and a cross-linking agent into a sugarcoating machine, and independently preparing a certain volume of inner core of the self-repairing microsphere with the core-shell structure; (2) coating a layer of cement outside the inner core to serve as a shell of the self-repairing microsphere, and curing under standard conditions; and (3) adhering a layer of organic film on the surface of the self-repairing microsphere after the maintenance is finished. The self-repairing microsphere with the core-shell structure can quickly form hydrogel in a crack area, so that the surface repairing rate of the crack is increased, the water penetration resistance of the crack is enhanced, and the rapid sealing of the crack of a cement-based material is realized.
本发明公开了一种快速封闭修复的水泥基材料及其制备方法和应用，该水泥基材料包括水凝胶单体微球和交联剂微球，两种微球均为核壳型结构，内核为水凝胶单体或交联剂，外壳为水泥，微球表面附着一层疏水有机薄膜，制备步骤为：(1)将水凝胶单体、交联剂分别加入糖衣机中，单独制备出一定体积的核壳结构自修复微球的内核；(2)在内核外包覆一层水泥作为自修复微球的外壳，放置于标准条件下进行养护；(3)养护完毕后在自修复微球表面附着一层有机薄膜。本发明的核壳结构的自修复微球可以快速地在裂缝区域形成水凝胶，提升裂缝的表面修复率，增强裂缝的抗水渗透能力，实现水泥基材料裂缝的快速封闭。
