The invention discloses a cement grinding aid, and belongs to the technical field of cement process additives. The grinding aid is prepared from, by weight, 40-60% of carboxylic acid polymer, 3-6% ofpolyhydric alcohol, 2-5% of a complexing enhancing substance, 2-5% of glycidyltrimethylammonium chloride, 1-3% of calcium formate, 2-5% of sodium p-benzylaminobenzenesulfonate, and the balance of water. The product is good in grinding assisting effect, capable of remarkably improving the grinding efficiency of cement, wide in application range, good in adaptability to cement taking fly ash, mineral slag, coal gangue, furnace slag and the like as mixed materials, and suitable for various Portland cement, fly ash cement, mineral slag cement and pozzolanic cement.
本发明公开一种水泥助磨剂，属于水泥工艺外加剂技术领域。本发明助磨剂是由以下重量份的原料组成：羧酸聚合物40%‑60%、多元醇3%‑6%、络合增强物质2%‑5%、缩水甘油三甲基氯化铵2%‑5%、甲酸钙1%‑3%、对苄氨基苯磺酸钠2%‑5%、余量为水。本发明产品助磨效果好，可显著提高水泥的粉磨效率，适应范围广，对以粉煤灰、矿渣、煤矸石、炉渣等为混合材的水泥均有很好的适应性，适用于各种硅酸盐水泥、粉煤灰水泥、矿渣水泥以及火山灰水泥。
