Preparation method of high-performance cement grinding aid
The invention relates to a preparation method of a high-performance cement grinding aid, which comprises the following steps: reacting ethanolamine with maleic anhydride to form esterified alcohol amine, copolymerizing with acrylamide methylpropanesulfonic acid to obtain polymeric alcohol amine, and compounding with diethanolisopropanolamine, triethanolamine, ethylene glycol, calcium formate and magnesium acetate to obtain the high-performance cement grinding aid free of alkali and chloride ions. When the grinding aid is applied to the cement grinding process, the grinding efficiency can be improved, and the energy consumption can be reduced; the cement strength can be improved, so that the clinker proportion is reduced. As a cost-reducing and effect-increasing product, the invention not only reduces the cost of a cement plant, but also contributes to carbon neutralization.
本发明涉及一种高性能水泥助磨剂的制备方法，用乙醇胺和马来酸酐反应成酯化醇胺，与丙烯酰胺甲基丙磺酸共聚，得到聚合醇胺，再复配二乙醇单异丙醇胺、三乙醇胺、乙二醇、甲酸钙、乙酸镁得到一种不含碱和氯离子的高性能水泥助磨剂。该助磨剂应用于水泥粉磨过程，不仅可以提高粉磨效率，降低能耗；还可以提高水泥强度，从而降低熟料比例。本发明作为一种降本增效产品，既为水泥厂降低成本，也为碳中和作出贡献。
