Concrete inorganic powder corrosion and rust inhibitor
The invention discloses a concrete inorganic powder anticorrosion rust inhibitor, and relates to the technical field of concrete admixtures, the concrete inorganic powder anticorrosion rust inhibitor comprises, by mass, 10-20 parts of an inorganic anticorrosion component, 10-20 parts of modified calcium aluminum hydrotalcite, and 60-80 parts of a dense reinforcing component; the modified calcium-aluminum hydrotalcite is prepared by the following steps: adding water into calcium-aluminum hydrotalcite and ammonium molybdate, uniformly stirring, and adjusting the pH value by using a Na2HPO4-NaH2PO4 buffer solution; and then carrying out hydrothermal reaction, filtering, taking filter residues, washing and drying. According to the concrete inorganic powder anti-corrosion and anti-rust agent provided by the invention, the calcium-aluminum hydrotalcite and the molybdate are combined for use, so that compared with the single use of the calcium-aluminum hydrotalcite and/or ammonium molybdate, the anti-corrosion and anti-rust effects are better, the chloride ion permeability coefficient ratio is less than or equal to 75%, the corrosion electric quantity ratio is less than or equal to 45%, and the concrete inorganic powder anti-corrosion and anti-rust agent is far higher than the national standard and mainstream products in the market.
本发明公开了一种混凝土无机粉体防腐阻锈剂，涉及混凝土外加剂技术领域，按质量份数包括无机防腐组分10‑20份，改性钙铝水滑石10‑20份，密实增强组分60‑80份；改性钙铝水滑石是将钙铝水滑石与钼酸铵加水搅拌均匀，使用Na2HPO4‑NaH2PO4缓冲液调节pH值；然后水热反应，过滤取滤渣，洗涤、干燥后得到。本发明提供了的混凝土无机粉体防腐阻锈剂，通过将钙铝水滑石和钼酸盐联合使用，相比于单独使用钙铝水滑石和/或钼酸铵，防腐阻锈效果更好，氯离子渗透系数比≤75％，腐蚀电量比≤45％，远高于国家标准和市场上的主流产品。
