Intelligent self-repairing waterproof material used in waterproof concrete
The invention relates to the technical field of waterproof concrete, in particular to an intelligent self-repairing waterproof material used in waterproof concrete. The self-repairing mortar is prepared from the following raw materials in parts by weight: 20-50 parts of cement, 15-25 parts of iron tailing sand, 8-16 parts of glass powder, 5-10 parts of ground calcium carbonate, 0.1-0.5 part of a water reducing agent, 0.2-0.8 part of polyvinyl alcohol fibers, 0.5-1.3 parts of redispersible latex powder, 0.2-0.6 part of a slurry dispersion stabilizer, 1-3 parts of a calcium ion supplement and 5-12 parts of self-repairing microcapsules. The intelligent self-repairing waterproof material can be used for filling and repairing fine cracks formed by concrete, the effect of compacting the concrete is achieved, the anti-permeability and waterproof performance of the concrete is improved, meanwhile, the capsule core material in the self-repairing micro-capsule can be slowly released, the slow release effect is achieved, the self-repairing micro-capsule has repeated practicability, and the waterproof performance of the concrete is improved. And repeated cracks of the concrete in subsequent use are repeatedly repaired, so that an efficient repairing effect is achieved.
本发明涉及防水混凝土技术领域，具体涉及一种用于防水混凝土中的智能自修复防水材料，其由以下重量份的原料制成：水泥20‑50份、铁尾矿砂15‑25份、玻璃粉8‑16份、重钙5‑10份、减水剂0.1‑0.5份、聚乙烯醇纤维0.2‑0.8份、可再分散乳胶粉0.5‑1.3份、浆体分散稳定剂0.2‑0.6份、钙离子补充剂1‑3份、自修复微囊5‑12份。本发明中的智能自修复防水材料，可以对混凝土形成的细小裂纹进行填充修补，起到密实混凝土的作用，提高混凝土的抗渗防水，同时，自修复微囊中的囊芯材料可以缓慢释放出来，达到缓释的效果，使得自修复微囊具有了重复实用性，对混凝土在后续使用中反复出现的裂纹进行重复性的修复，从而实现高效的修复效果。
