The invention provides an enhanced mineral powder grinding aid and a preparation method thereof. The enhanced mineral powder grinding aid is prepared by compounding a dispersing agent, a defect inducer, a dispersion correction component and polymeric polyol, wherein the dispersing agent is prepared by carrying out addition on 3-methyl-2-butene-1-alcohol and epoxide and then polymerizing with an alcohol ether small monomer to prepare a medium-low molecular weight polymer; the defect inducer and the dispersion correction component are respectively prepared by polymerizing N-ethyl methacrylamide, tiglic acid and epoxide. The mineral powder grinding aid provided by the invention can improve the mineral powder activity and reduce the grinding energy consumption, and the mineral powder grinding aid can optimize the particle size distribution of mineral powder grinding, improve the mineral powder hydration activity and further improve the hydration strength.
本发明提供了一种增强型矿粉助磨剂及其制备方法。所述增强型矿粉助磨剂由分散剂、缺陷诱导剂、分散校正组分和聚合多元醇复配所得，所述分散剂由3‑甲基‑2‑丁烯‑1‑醇与环氧化物加成，再与醇醚小单体聚合制备中低分子量聚合物；所述缺陷诱导剂、分散校正组分分别由N‑乙基甲基丙烯胺、惕格酸与环氧化物聚合制得。本发明提供一种能提高矿粉活性，降低粉磨能耗的矿粉粉磨助磨剂，该助磨剂可优化矿粉粉磨的粒径分布，提高矿粉水化活性，进而提高水化强度。
