Composite acetone enhanced alkali-free liquid setting accelerator
The invention discloses a composite acetone enhanced alkali-free liquid setting accelerator. An existing alkali-free liquid setting accelerator has the main problems that unstable phenomena such as devitrification and layering can occur after the product is placed for 1-2 months, and the 1d compressive strength of most products cannot meet the standard requirement. The alkali-free liquid setting accelerator comprises the components: fluosilicic acid, aluminum hydroxide, acrylic acid, aluminum sulfate, zinc oxide, magnesium hydroxide, magnesium silicate, potassium hydroxide, a suspending agent, acetone, a stabilizing enhancer and tap water. The stabilizing enhancer comprises the components: acetone, urea, methanol or ethanol and glycerol. The alkali-free liquid setting accelerator is simple to produce, non-toxic and pollution-free, the product does not crystallize after being placed for half a year, the placement stability of the alkali-free liquid setting accelerator product is ensured through a multi-component composite superimposed effect, the expressive force of site construction is improved, the rebound rate is reduced, the 1 d compressive strength is improved, and it is ensured that the later strength does not shrink.
本发明公开了一种复合丙酮增强无碱液体速凝剂。现有无碱液体速凝剂目前面临的主要问题是产品放置1‑2个月内会出现析晶分层等不稳定现象，多数产品1d抗压强度达不到标准要求。本发明组成成分为氟硅酸，氢氧化铝，丙烯酸，硫酸铝，氧化锌，氢氧化镁，硅酸镁，氢氧化钾，悬浮剂，丙酮，稳定增强剂，自来水；稳定增强剂组成成分为：丙酮、尿素、甲醇或乙醇、丙三醇。本发明生产简单、无毒无污染，产品放置半年不析晶，通过多组分复合叠加效应保证了无碱液体速凝剂产品的放置稳定性，提高了现场施工的表现力，降低了回弹率，提高了1d抗压强度，保证了后期强度不倒缩。
