Cement grinding aid, preparation method and application thereof
The invention provides a cement grinding aid, a preparation method and application thereof. The cement grinding aid comprises polymeric polyol, sodium tripolyphosphate and calcium lignosulphonate. The invention also provides a preparation method of the cement grinding aid. According to the invention, the cement grinding aid provided by the invention not only can improve the grinding aiding effect, improve the fineness of cement, improve the fluidity and water-retaining property of the cement, but also can improve the early and later strength of the cement; and the grinding aid provided by the invention is simple in formula, the addition amount of alcohol amine substances is reduced, the production cost of the grinding aid is reduced, the environmental protection property of the grinding aid is improved, the unit cost in the cement production process can be reduced, resources are saved, and the carbon emission is reduced.
本发明提供了一种水泥助磨剂及其制备方法和应用，所述水泥助磨剂包括聚合多元醇、三聚磷酸钠和木钙。本发明还提供了所述水泥助磨剂的制备方法。本发明提供的水泥助磨剂不仅能够提高助磨效果，提高水泥的细度、改善水泥的流动性和保水性，还可以提高水泥早期及后期强度；同时，本发明提供的助磨剂配方简单，减少醇胺类物质的加入量，降低助磨剂的生产成本、提高助磨剂的环保性，并且可降低水泥生产过程中单位成本、节约资源、减少碳排放量。
