Liquid alkali-free setting accelerator and preparation method thereof
The invention discloses a liquid alkali-free setting accelerator and a preparation method thereof. The liquid alkali-free setting accelerator is prepared from the following raw materials in percentageby weight: 40-70% of aluminum sulfate, 1-5% of a reinforcing agent, 0.1-5% of a dispersing agent, 0.1-1% of a thickening agent, 0.1-10% of organic alcohol amine and the balance of water, totaling 100%. The liquid alkali-free setting accelerator is prepared at normal temperature, extra heating is not needed in the production process, and energy conservation and environmental protection are achieved; wherein the mixing amount is 6-9%, the initial setting time is less than 5 minutes, the final setting time is less than 12 minutes, the one-day strength is more than 7 MPa, and the 28-day strengthis not lost; the storage stability is good, and precipitate and layering are avoided after 3 months.
本发明公开了一种液体无碱速凝剂及其制备方法，所述液体无碱速凝剂由如下重量百分比的原料组成：硫酸铝40‑70%，增强剂1‑5%，分散剂0.1‑5%，增稠剂0.1‑1%，有机醇胺0.1‑10%，余量为水，补足100%。所述的液体无碱速凝剂常温制备，生产过程无需额外加热，节能环保；掺量6‑9%，初凝时间小于5分钟，终凝时间小于12分钟，1天强度大于7兆帕，28天强度无损失；储存稳定性好，3个月无沉淀无分层。
