Cement raw material grinding aid as well as preparation method and application thereof
The invention provides a cement raw material grinding aid as well as a preparation method and application thereof, and relates to the technical field of cement production, the cement raw material grinding aid comprises the following components: sodium polyacrylate, copper N, N-dibutyldithiocarbamate, metal salt and water; the weight-average molecular weight of the sodium polyacrylate is 200 to 5000; the sodium polyacrylate comprises at least one of sodium polyacrylate with the weight-average molecular weight of 200 to 800 and sodium polyacrylate with the weight-average molecular weight of 3000 to 4000; the metal salt comprises at least one of zinc nitrate, barium nitrate, lanthanum nitrate and cerium nitrate. The cement raw material grinding aid solves the technical problems of unstable grinding-aiding and yield-increasing effects and poor coal-saving effect of the cement raw material grinding aid in the prior art, and achieves the technical effects of remarkably improving the grinding-aiding and yield-increasing effects of the cement raw material, effectively reducing coal consumption and realizing stable application.
本发明提供了一种水泥生料助磨剂及其制备方法、应用，涉及水泥生产的技术领域，该水泥生料助磨剂包括以下组分：聚丙烯酸钠、N,N‑二丁基二硫代氨基甲酸铜、金属盐，以及水；聚丙烯酸钠的重均分子量为200‑5000；聚丙烯酸钠包括重均分子量200‑800的聚丙烯酸钠和重均分子量3000‑4000的聚丙烯酸钠中的至少一种；金属盐包括硝酸锌、硝酸钡、硝酸镧以及硝酸铈中的至少一种。本发明解决了现有技术中水泥生料助磨剂存在助磨提产效果不稳定和节煤效果不佳的技术问题，达到了显著提升水泥生料的助磨提产、有效降低煤耗，以及能够实现稳定应用的技术效果。
