Fluorine-free alkali-free accelerator and preparation method thereof
The invention discloses a fluoride-free alkali-free accelerator and a preparation method, the formula comprises a pH regulator, aluminum sulfate, a reinforcing agent and water, and the preparation method comprises the following steps: step 1, weighing raw materials; 2, mixing the raw materials; step 3, adjusting the pH value; and step 4, packaging and storing. In the first step, the content of each component is as follows: 0.1% of phosphoric acid, 0.1% of ammonia water, 55% of aluminum sulfate, 2% of diethanol amine, 1% of triethanolamine and 41.8% of water; the concentration of the phosphoric acid is 98%, and the concentration of the ammonia water is 25%; the water is purified water; the alkali-free accelerator is prepared through complete complexation reaction of aluminum sulfate and organic amine, strong acid such as hydrofluoric acid does not need to be added into raw materials, the mixing amount of the alkali-free accelerator can be reduced, meanwhile, the high solidification rate is guaranteed, the alkali-free accelerator has high strength, and the product is safe, reliable, green and environmentally friendly; the ultrasonic stirring technology is adopted for raw material mixing, and the method has the advantages of being high in efficiency, short in stirring time and easy to operate.
本发明公开了一种无氟无碱速凝剂及制备方法，配方包括：pH调节剂、硫酸铝、增强剂和水，制备方法包括步骤一，称取原料；步骤二，原料混合；步骤三，调节pH；步骤四，包装储存；所述步骤一中，各组分的含量具体为：0.1％的磷酸、0.1％的氨水、55％的硫酸铝、2％的二乙醇胺、1％的三乙醇胺和41.8％的水；所述磷酸的浓度为98％，氨水的浓度为25％；所述水为纯化水；本发明通过硫酸铝与有机胺的完全络合反应制得，原料无需加入氢氟酸等强酸，便能够在减少无碱速凝剂掺量的同时，保证较快的凝固速率，具有较高的强度，且产品安全可靠、绿色环保；本发明采用超声搅拌工艺进行原料混合，具有效率高、搅拌时间短、操作简单的优点。
