Cement-based material crack self-repairing particle and preparation and use methods thereof
The invention discloses a cement-based material crack self-repairing particle and a preparation and use method thereof. The cement-based material crack self-repairing particle comprises functional microorganisms, a carrier and an outer protective layer, the functional microorganisms are loaded in the carrier; the outer protection layer wraps the outer surface of the carrier; the preparation method comprises the following steps: firstly modifying the carrier, then loading the functional microorganisms in the carrier, and then wrapping the carrier with the outer protective layer. When the self-repairing particles are used, the self-repairing particles are directly doped into the cement-based material, and nutritional agents can also be added, so that cracks can be automatically repaired when the cement-based material generates the cracks. The self-repairing particles are doped into the cement-based material, so that the mechanical property of the cement-based material cannot be reduced like existing self-repairing particles, even the mechanical property of the cement-based material can be improved, the durability of the cement-based material is improved, the crack repairing effect is good, and contacted sewage can be purified to a certain extent.
本发明公开了一种水泥基材料裂缝自修复颗粒及其制备、使用方法，包括功能微生物、载体和外保护层；所述功能微生物负载于载体中；所述外保护层包裹于载体外表面；制备方法为先改性载体，随后将功能微生物负载于载体中，随后在载体外部包裹外保护层。在使用时直接将自修复颗粒掺入水泥基材料中，还可加入营养剂，便可在水泥基材料产生裂缝时，自动修复裂缝。本发明的自修复颗粒掺入水泥基材料中不仅不会像现有自修复颗粒一样降低水泥基材料的力学性能，甚至还能提升水泥基材料的力学性能，提升水泥基材料的耐久性，并且修复裂缝的效果好，还能够对接触的污水产生一定程度的净化。
