Accelerating agent and preparation method thereof
The invention discloses an accelerator and a preparation method thereof. The aluminum sulfate and the fluorine-containing aluminum complex are used as main components of the composite accelerator, the diethanol amine and the tartaric acid are used as composite complexing agents, the early strength agent NaF is supplemented, and the performance of the accelerator is optimized by continuously adjusting the process formula. According to the formula obtained after a large number of tests, the initial setting time of the accelerator can be shorter than 3.5 min, the final setting time of the accelerator can be shorter than 5.5 min, and the 90-day compressive strength of cement can be higher than 60 MPa.
一种速凝剂及其制备方法。本发明以硫酸铝和含氟的铝络合物为复合速凝剂的主体成分，以二乙醇胺和酒石酸作为复合络合剂，并辅以早强剂NaF，通过不断地调整工艺配方以优化速凝剂的性能。在大量的试验后得到的配方可使速凝剂的初凝时间低于3.5min，终凝时间低于5.5min，并使水泥的90d抗压强度高于60MPa。
