Capillary crystallization type anti-corrosion waterproof material and preparation method thereof
The invention discloses a capillary crystalline anticorrosive waterproof material and a preparation method thereof, and belongs to the technical field of concrete admixtures. The permeable crystallization type anti-corrosion waterproof material is prepared from the following components in parts by weight: 100 parts of water glass, 0.1 to 2 parts of nano hydrated calcium silicate seed crystal, 0.3 to 1 part of complexing dispersant, 30 to 90 parts of regulator and 0.01 to 0.02 part of penetrant. According to the permeable crystallization type anti-corrosion waterproof material, the nano calcium silicate hydrate seed crystal is adopted as a crystallizing agent, the nano calcium silicate hydrate seed crystal is compact in structure, the nano calcium silicate hydrate seed crystal is added as a seed, silicate is induced to be subjected to crystallization reaction, gel with the same compact structure is formed, and the generated gel is very stable, so that the permeable crystallization type anti-corrosion waterproof material has a good anti-corrosion effect. And acid and alkali corrosion resistance and salt ion corrosion resistance can be achieved. According to the invention, by adding the regulator dilute acid or dilute alkali, the silicic acid group in the solution keeps a reasonable space structure, and the gelation reaction time of the waterproof material is regulated, so that the waterproof material can meet the requirements of concrete with different compactness.
本发明公开一种渗透结晶型防腐防水材料及其制备方法，属于混凝土外加剂技术领域。一种渗透结晶型防腐防水材料，包括以下重量份数的各组分：水玻璃100份、纳米水化硅酸钙晶种0.1～2份、络合分散剂0.3～1份、调节剂30～90份、渗透剂0.01～0.02份。本发明的渗透结晶型防腐防水材料，采用纳米水化硅酸钙晶种作为结晶剂，该纳米水硅酸钙晶种结构致密，本发明通过加入纳米水化硅酸钙晶种作为种子，诱导硅酸盐发生结晶化反应，形成同样结构致密的凝胶，且生成的凝胶非常稳定，可以耐酸碱腐蚀，耐盐离子腐蚀。本发明通过添加调节剂稀酸或稀碱，使溶液中的硅酸基团保持合理的空间结构，调节防水材料的凝胶化反应时间，使其可以满足不同密实度的混凝土。
