Preparation method of coagulant for castable, coagulant prepared by preparation method and application of coagulant
The invention belongs to the technical field of new building materials, and particularly relates to a preparation method of a coagulant for castable. The preparation method comprises the following steps: (1) adding cement and melamine into water, and stirring for reaction to obtain mixed slurry; (2) carrying out low-speed centrifugation on the mixed slurry, and collecting an upper-layer suspension after the low-speed centrifugation is finished; (3) carrying out centrifugal treatment on the suspension, and collecting a solid precipitate; sequentially freezing and drying the solid precipitate under a vacuum condition to obtain powder; and uniformly mixing the powder with a grinding aid, and grinding to obtain the coagulant for the castable. The prepared coagulant not only can shorten the coagulation time of the calcium aluminate cement combined castable, but also can improve the demolding strength and drying strength of the cement combined castable, greatly improves the production efficiency and economic benefits of cement combined castable prefabricated parts, and has great commercial application value.
本发明属于建筑新材料技术领域，具体涉及一种浇注料用促凝剂的制备方法。上述制备方法的步骤为：（1）将水泥、三聚氰胺加入水中，搅拌反应，得到混合浆料；（2）将混合浆料进行低速离心，低速离心结束后收集上层悬浮液；（3）将悬浮液进行离心处理，收集固体沉淀物；将固体沉淀物在真空条件下依次进行冷冻、干燥，得到粉料；将粉料与助磨剂混合均匀后进行粉磨，得到浇注料用促凝剂。本发明制备的促凝剂不仅能够缩短铝酸钙水泥结合浇注料的凝固时间，同时还能提高水泥结合浇注料的脱模强度和干燥强度，极大地提高了水泥结合浇注料预制件的生产效率和经济效益，具有极大的商业应用价值。
