Liquid accelerator and preparation method thereof
The invention provides a liquid accelerator and a preparation method thereof, and relates to the technical field of accelerator preparation. The preparation method of the liquid accelerator comprises the following steps: 1) preparing a liquid sodium aluminate solution; 2) adding modified fluoride salt: adding water into the liquid sodium aluminate solution, and uniformly stirring; then adding the modified fluoride salt into the liquid sodium aluminate solution, stirring, and reacting for 0.5-1 hour at the temperature of 50-80 DEG C; 3) adding aluminum sulfate: adding aluminum sulfate within 10-30 minutes after the fluoride salt is completely reacted, and continuously reacting for 1-2 hours; and 4) adding organic alcohol amine, and stirring for 0.5-1 hour to obtain the liquid accelerator which has better viscosity stability.
本发明提供一种液体速凝剂及其制备方法，涉及速凝剂制备技术领域。液体速凝剂的制备方法，包括如下步骤：1)制备液体铝酸钠溶液；2)加入改性氟化盐：将水加入到所述液体铝酸钠溶液中，搅拌均匀；然后将所述改性氟化盐加入到所述液体铝酸钠溶液中，搅拌，50～80℃下反应0.5～1h；3)加入硫酸铝：在氟化盐反应完全后的10～30min内，添加硫酸铝，继续反应1～2h；4)加入有机醇胺，搅拌0.5～1h即制得液体速凝剂，该液体速凝剂具有较好的粘度稳定性。
