The invention provides a cement grinding aid and a preparation method thereof, and belongs to the technical field of cement manufacturing, wherein the cement grinding aid is prepared from the following raw materials in parts by weight: 70-120 parts of a composite fermentation product, 5-12 parts of talcum powder, 10-30 parts of organic amines, 12-20 parts of a surfactant, 2-5 parts of calcium lignosulphonate, and 100-200 parts of water; and the compound fermentation product is a fermentation product of a mixed substrate of beet molasses, flaxseeds and lignin. The cement grinding aid provided by the invention has the advantages of easily available raw materials, low price, simple and feasible preparation method, mild reaction conditions and low requirements on reaction equipment, and is suitable for industrial production. The cement grinding aid does not contain any chloride ion component, is non-toxic, green, environment-friendly and non-corrosive, and does not damage human bodies, buildings and the like; and the cement grinding aid provided by the invention meets the standard requirements of the grinding aid, has an excellent grinding aiding effect, can improve the compressive strength, and is low in doping amount which is only 0.03-0.04% of the use amount of cement.
本发明提出了一种水泥助磨剂及其制备方法，属于水泥制造技术领域，由以下原料按重量份制备而成：复合发酵物70‑120份、滑石粉5‑12份、有机胺类10‑30份、表面活性剂12‑20份、木质素磺酸钙2‑5份、水100‑200份；所述复合发酵物是甜菜糖蜜、亚麻籽、木质素的混合底物的发酵物。本发明提供的水泥助磨剂，原料易得，价格低廉，制备方法简单易行，反应条件温和，对反应设备要求不高，适合工业化生产。不含任何氯离子成分，无毒、绿色环保，无腐蚀性，对人体及建筑等没有损害；本发明所述的水泥助磨剂满足助磨剂标准要求，且具有优异的助磨效果，能够提高抗压强度，本发明的水泥助磨剂掺入量低，仅为水泥用量的0.03‑0.04％。
