Inorganic water-based capillary crystalline waterproof agent as well as preparation and use methods thereof
The invention discloses an inorganic water-based permeable crystallization type waterproof agent and preparation and use methods thereof, and belongs to the field of waterproof materials for concrete, the inorganic water-based permeable crystallization type waterproof agent is at least prepared from the following raw materials by mass: 55.2%-75.1% of lithium silicate, 2.0%-3.6% of sodium hydroxide, 0.8%-1.6% of potassium hydroxide, 0.8%-1.6% of a reaction accelerator, and the balance of water. The anti-cracking coating is prepared from the following components in percentage by weight: 0.1 to 0.15 percent of surfactant, 0.3 to 0.6 percent of film-forming agent, 0.4 to 0.8 percent of anti-cracking fiber and the balance of deionized water. Lithium silicate with small lithium ion radius is mixed with sodium hydroxide, potassium hydroxide and other assistants, the mixture can chemically react with calcium hydroxide in a concrete structure to generate C-S-H gel, and the branch-tendril-shaped C-S-H gel is mutually lapped to form a spatial net structure, so that the compactness of the concrete can be increased, an integral waterproof material is formed, and the waterproof performance of the concrete is improved. Therefore, the mechanical strength of a concrete structure can be improved, and the service life of concrete is prolonged.
本发明公开了一种无机水性渗透结晶型防水剂及其制备和使用方法，属于混凝土用防水材料领域，无机水性渗透结晶型防水剂按质量百分比计至少由如下原料制备而成：硅酸锂55.2％～75.1％，氢氧化钠2.0％～3.6％，氢氧化钾0.8％～1.6％，反应促进剂0.8％～1.6％，表面活性剂0.1％～0.15％，成膜剂0.3％～0.6％，抗裂纤维0.4％～0.8％，其余为去离子水。本发明将锂离子半径较小的硅酸锂与氢氧化钠、氢氧化钾等助剂混合后可与混凝土结构内部中的氢氧化钙发生化学反应生成C‑S‑H凝胶，枝蔓状的C‑S‑H凝胶相互搭接，形成空间网状结构，可以增加混凝土的密实度，形成整体性防水材料，从而能够提高混凝土结构的机械强度，延长混凝土的使用寿命。
