Controllable permeable nano silicon ion protective agent and preparation method thereof
The invention discloses a controllable permeable nano silicon ion protective agent and a preparation method thereof. The protective agent is prepared from the following raw materials in parts by weight: 30-50 parts of sodium silicate, 5-20 parts of potassium silicate, 1-5 parts of lithium silicate, 20-30 parts of organic silicate, 2-6 parts of a penetrating agent, 0.5-2 parts of a dispersing agent, 0.2-1 part of a calcium ion sealing agent, 0.1-1 part of a gel retarder, 0.1-0.5 part of a stabilizer, 0.1-0.3 part of a coagulant, 0.1-0.3 part of a coagulation accelerating aid, 0.2-0.5 part of an anti-freezing agent and 100-120 parts of deionized water. The preparation method comprises the following steps: sequentially introducing the raw materials into a stirring tank according to the proportion, stirring for 30-50 minutes, and filtering and precipitating to obtain the product. The protective agent can regulate and control the reaction speed according to different compactness of concrete, and also has multiple effects of crack healing, acid and alkali resistance, corrosion resistance, impermeability improvement, weathering prevention and the like.
本发明公开了一种可调控渗透型纳米硅离子防护剂及其制备方法，所述防护剂由以下重量份的原料制成：硅酸钠30‑50份、硅酸钾5‑20份、硅酸锂1‑5份、有机硅酸盐20‑30份、渗透剂2‑6份、分散剂0.5‑2份、钙离子封闭剂0.2‑1份、凝胶延迟剂0.1‑1份、稳定剂0.1‑0.5份、促凝剂0.1‑0.3份、促凝助剂0.1‑0.3、防冻剂0.2‑0.5份、去离子水100‑120份。制备方法：按配比，将上述原料依次导入搅拌罐内，搅拌30‑50min后，过滤沉淀即得该产品。该防护剂可以因混凝土的密实度不同来调控反应速度，还具有裂缝愈合、耐酸碱、抗腐蚀、提高抗渗性能、防风化等多重效果。
