Anti-cracking self-repairing cement-based waterproof material and preparation method thereof
The invention discloses an anti-cracking self-repairing cement-based waterproof material and a preparation method thereof, and the anti-cracking self-repairing cement-based waterproof material is characterized by comprising the following raw materials by weight: 20-30 parts of cement; 25 to 40 parts of quartz sand; 5-10 parts of a filler; 7-9 parts of a microbial solution; 8-12 parts of a porous material; 2-5 parts of calcium lactate; 1-2 parts of urea; 18 to 23 parts of redispersible rubber powder; and 1-2 parts of a dry powder additive. Microorganisms in the waterproof material can chemically react with calcium ions when encountering water and in an environment with nutrients, water-insoluble crystals are produced, cracks generated in the later period of a waterproof layer can be effectively blocked, the microorganisms are adsorbed in a porous material, and under the wrapping of a polymer macromolecular chain formed by the redispersible rubber powder, the waterproof performance of the waterproof material is improved. The waterproof agent can keep activity in a cement-based waterproof layer for a long time, and has relatively strong self-repairing and anti-cracking capabilities, and the effective service life of the waterproof layer is greatly prolonged.
本发明公开了一种抗开裂自修复水泥基防水材料及其制备方法，包括以下重量份的原料：一种抗开裂自修复水泥基防水材料，其特征在于，包括以下重量份原料：水泥20‑30份；石英砂25‑40份；填料5‑10份；微生物溶液7‑9份；多孔材料8‑12份；乳酸钙2‑5份；尿素1‑2份；可再分散性胶粉18‑23份；干粉助剂1‑2份。本发明防水材料中的微生物遇到水份，在有营养物的环境下，会与钙离子发生化学反应，生产难溶于水的晶体，能够有效封堵防水层后期产生的裂缝，将微生物吸附在多孔材料中，并且在可再分散性胶粉形成的聚合物高分子链的包裹下，能够在水泥基防水层内长期保持活性，且具有较强的自修复及抗开裂能力，大幅延长防水层的有效使用寿命。
