The invention discloses a liquid alkali-free accelerator and a preparation method thereof. The liquid alkali-free accelerator comprises the following components: aluminum sulfate, a reinforcing agent, a dispersing agent, a thickening agent, organic alcohol amine and the balance of organic alcohol amine. The strength of the accelerator suspension is rapidly increased within one day through the reinforcing agent, effective dispersion of the accelerator suspension is achieved through the dispersing agent, the setting time of the accelerator suspension is shortened through the organic alcohol amine, and the storage stability of the accelerator suspension is improved through the thickening agent. The liquid alkali-free accelerator is prepared at normal temperature, does not need additional heating, and is energy-saving and environment-friendly; the mixing amount is 6-9 wt%, the initial setting time is less than 5 minutes, the final setting time is less than 12 minutes, the strength in one day is greater than 7 MPa, and the strength is not lost in 28 days; the storage stability is good, and precipitation and layering are avoided within 3 months.
本发明公开了一种液体无碱速凝剂及其制备方法。本发明所述液体无碱速凝剂组分包括硫酸铝、增强剂、分散剂、增稠剂、有机醇胺及余量；通过增强剂实现其1天强度的快速增长，通过分散剂实现速凝剂悬浮体的有效分散，通过有机醇胺缩短其凝结时间，通过增稠剂提高速凝剂悬浮体的储存稳定性。本发明所述液体无碱速凝剂采用常温制备，不需要额外加热，节能环保；掺量6‑9wt%，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。
