Simple liquid alkali-free setting accelerator and preparation method thereof
The invention discloses a simple liquid alkali-free setting accelerator and a preparation method thereof. The setting accelerator comprises the following raw material components in parts by mass: 300-400 parts of tap water, 20-60 parts of mineral powder, 450-550 parts of aluminum sulfate, 20-60 parts of organic amine, 1-10 parts of organic acid, 50-100 parts of fluorine-silicon compound and 5-20 parts of a suspending agent. The mineral powder is one or two of kaolin, bauxite, calcium aluminate and calcium carbonate, and the particle size of the mineral powder is 100-500 meshes; the organic amine is one or more of triisopropanolamine, diethylenetriamine, triethylene tetramine and triethanolamine; the fluorine-silicon compound is one or two of fluosilicic acid, ammonium fluosilicate and zincfluosilicate; and the suspending agent is ultrafine powder of diatomite, bentonite and hydrated magnesium silicate. The invention also provides a preparation method of the accelerator. The inventionrelates to a liquid alkali-free setting accelerator containing polyaluminum sulfate, which can be produced under simple preparation process conditions, and simultaneously confirms that the setting time of the alkali-free setting accelerator meets the national standard.
一种简易液体无碱速凝剂及其制备方法，所述速凝剂的原料组分与质量比如下：自来水∶矿粉∶硫酸铝∶有机胺∶有机酸∶氟硅化合物∶悬浮剂＝(300～400)∶(20～60)∶(450～550)∶(20～60)∶(1～10)∶(50～100)∶(5～20)。矿粉是高岭土、铝土矿、铝酸钙、碳酸钙中的一种或两种，矿粉的粒度为100目～500目；有机胺为三异丙醇胺、二乙烯三胺、三乙烯四胺、三乙醇胺中的一种或几种；氟硅化合物为氟硅酸、氟硅酸铵、氟硅酸锌的一种或两种；悬浮剂为硅藻土、膨润土、水合硅酸镁超细粉。还提供了所述速凝剂的制备方法。本发明是一种含聚合硫酸铝的液体无碱速凝剂，它能在比较简易的制备工艺条件下生产，同时确证无碱速凝剂的凝结时间满足国家标准。
