Preparation method of alkali-free setting accelerator
The invention discloses a preparation method of an alkali-free setting accelerator. The alkali-free setting accelerator comprises the following components in percentage by mass: 5-7% of fluorosilicicacid, 3-5% of aluminum hydroxide, 19-25% of aluminum sulfate, 5-10% of citric acid, 1-3% of a polyhydroxyl dispersion enhancer, 0.5-1% of a stabilizer and the balance of water. The alkali-free settingaccelerator is prepared from following main components: aluminum fluorosilicate, aluminum fluoride, aluminum sulfate, citric acid, a polyhydroxyl dispersion enhancer and a stabilizer, and is good inaccelerating performance by means of the excellent accelerating effect of the fluorine-aluminum complexing solution.
本发明公开了一种无碱速凝剂的制备方法，无碱速凝剂以质量百分数计配方为：氟硅酸5‑7％，氢氧化铝3‑5％，硫酸铝19‑25％，柠檬酸5‑10％，多羟基分散增强剂1‑3％，稳定剂0.5‑1％，余量为水。本发明以氟硅酸铝、氟化铝、硫酸铝、柠檬酸、多羟基分散增强剂、稳定剂为主要成分组成的无碱液体速凝剂，借助于氟铝络合溶液优异的促凝作用，速凝性能好。
