Delayed coagulation type cement grinding aid as well as preparation method and application thereof
The invention relates to a delayed coagulation type cement grinding aid as well as a preparation method and application thereof, and belongs to the technical field of cement. The delayed coagulation type cement grinding aid comprises the following raw materials: water, industrial salt, white granulated sugar, diethanolisopropanolamine, and one or two of triethanolamine and glycerol. The delayed coagulation type cement grinding aid not only has a good grinding aid effect on cement, reduces the fineness of the cement and optimizes the grain composition of the cement, but also has a good delayedcoagulation effect, prolongs the initial setting time and the final setting time of the cement, and has a wider application range so as to meet the requirements of long-time storage or long-distance transportation of the cement. In the water, the industrial salt is firstly added, then the white granulated sugar is added, and then the triethanolamine, and the glycerol and the diethanolisopropanolamine are added. Not only is the dissolution rate of the white granulated sugar increased, but also the stability of the grinding aid is improved, and the process of the grinding aid is simple and convenient to control.
本发明涉及一种缓凝型水泥助磨剂及其制备方法与应用，属于水泥技术领域，缓凝型水泥助磨剂的原料包括水、工业盐、白砂糖、二乙醇单异丙醇胺、三乙醇胺或丙三醇中的一种或两种。该缓凝型水泥助磨剂其不仅对水泥具有良好的助磨作用，降低水泥的细度，优化水泥颗粒级配，同时还具有良好的缓凝作用，延长水泥的初凝时间、终凝时间，提高了助磨剂的适用范围，以满足水泥长时间停放或长距离运输的需求。在水中，首先加入工业盐，再加入白砂糖，然后加入三乙醇胺、丙三醇、二乙醇单异丙醇胺，不仅加快了白砂糖的溶解速率，而且提高了助磨剂的稳定性，使助磨剂的工艺简便、便于控制。
