The invention relates to the technical field of functional material preparation, in particular to the field of IPC C04B24, and further relates to a cement grinding aid and a preparation method thereof. The water-retaining agent comprises the following raw materials in parts by mass: 15-35 parts of polymeric polyol, 5-20 parts of a reinforcing agent, 5-15 parts of a water reducing agent, 3-10 parts of a water-retaining agent, 3-8 parts of ethanolamine and 50-100 parts of water. The prepared cement grinding aid does not contain chloride ions, is non-toxic, green and environment-friendly, and does not influence human bodies and buildings; the early strength and the later strength of cement can be improved, the fineness of the cement is improved, the fluidity of the cement is improved, the hardening speed is effectively increased, and the setting time is shortened. 本发明涉及功能材料制备技术领域，尤其涉及IPC C04B24领域，进一步的，涉及一种水泥助磨剂及其制备方法。按质量份计，其原料包括：聚合多元醇15～35份、增强剂5～20份、减水剂5～15份、保水剂3～10份、乙醇胺3～8份、水50～100份。本发明所制备的水泥助磨剂不含氯离子，无毒，绿色环保，不会
