Cement grinding aid as well as preparation method and application thereof
The invention provides a cement grinding aid as well as a preparation method and application thereof, and belongs to the technical field of cement. The preparation method comprises the following steps: preparing NH2-UiO-66, reacting the NH2-UiO-66 with maleic anhydride to prepare MA-NH2-UiO-66, and carrying out polymerization reaction on the MA-NH2-UiO-66, a monomer 1 prepared from maleic anhydride and diethanol amine, a monomer 2 prepared from maleic anhydride and diol, a silane coupling agent and allyl polyoxyethylene ether to prepare the cement grinding aid. The cement grinding aid prepared by the invention not only can play roles in improving cement particle distribution, exciting hydration power, improving early strength and later strength of cement and the like, but also is beneficial to improving a grinding process in a cement production process, and plays an important role in reducing energy consumption and improving the use efficiency of energy; wide application prospects are realized.
本发明提出了一种水泥助磨剂及其制备方法和应用，属于水泥技术领域。制备NH2‑UiO‑66，与马来酸酐反应制得MA‑NH2‑UiO‑66，与马来酸酐与二乙醇胺制得的单体1、马来酸酐与二醇制得的单体2和硅烷偶联剂和烯丙基聚氧乙烯醚聚合反应制得水泥助磨剂。本发明制得的水泥助磨剂不仅能够使水泥助磨剂在发挥改善水泥颗粒分布并激发水化动力、提高水泥早期强度和后期强度等作用，还有利于改善水泥生产过程中的粉磨工艺，而且对于降低能量消耗、提高能量的使用效率具有重要的作用，具有广阔的应用前景。
