Cement-based capillary crystalline waterproof material and preparation method thereof
The invention discloses a cement-based capillary crystalline waterproof material and a preparation method thereof, and relates to the technical field of preparation of capillary crystalline waterproof materials. The waterproof material comprises the following components in parts by weight: 50-70 parts of Portland cement, 30-40 parts of quartz sand, 2-3 parts of a complexing agent, 4-5 parts of a siliceous waterproof agent, 1-2 parts of a waterproof auxiliary agent, 5-6 parts of a crystallization auxiliary agent, 0.5-1.2 parts of a surfactant, 1-2 parts of a water reducing agent and 5-6 parts of nano inorganic powder. Active chemical substances in the capillary crystalline waterproof material can be dissolved in water and can be diffused into pores and cracks in concrete under the action of water, meanwhile, the chemical reaction of cement hydration byproducts and hydration products is accelerated, water-insoluble branch and tendril-shaped crystals are formed in the concrete, and therefore the concrete is compacted, and the waterproof performance of the concrete is improved. The impermeability and the durability are enhanced. The problem that an existing capillary crystalline waterproof material is poor in performance is solved.
本发明公开了一种水泥基渗透结晶型防水材料及其制备方法，本发明涉及渗透结晶型防水材料制备技术领域，该防水材料包括以下重量份组分：硅酸盐水泥50‑70份、石英砂30‑40份、络合剂2‑3份、硅质防水剂4‑5份、防水助剂1‑2份、结晶辅助剂5‑6份、表面活性剂0.5‑1.2份、减水剂1‑2份和纳米无机粉体5‑6份。本发明渗透结晶防水材料中的活性化学物质可溶于水，并在水的作用下扩散至混凝土内部孔隙和裂缝，同时加快了水泥水化副产物与水化产物的化学反应，在混凝土内部形成不溶于水的枝蔓状结晶体，从而密实混凝土，增强抗渗性和耐久性。本发明解决了现有渗透结晶防水材料性能较差的问题。
