Liquid grinding aid for high-alkali cement and preparation method of liquid grinding aid

The invention relates to a liquid grinding aid for high-alkali cement and a preparation method of the liquid grinding aid, and relates to the field of grinding aids, and the liquid grinding aid is prepared from the following raw materials in parts by weight: 15-25 parts of modified polyol amine ester, 7-12 parts of glycerol, 0.5-1.5 parts of sodium chloride, 3-6 parts of hydroxy carboxylate and 60-70 parts of water. The high-alkali cement grinding aid has the advantages that the grinding aiding effect on high-alkali cement is improved, the particle size grading of the high-alkali cement is optimized, the hydration process is promoted, and the morphology of a hydration product is improved, so that the strength of the high-alkali cement is improved. 本申请涉及一种用于高碱水泥的液体助磨剂及其制备方法，涉及助磨剂的领域，其所用原料包括以下重量份的组分：改性多元醇胺酯15-25份、丙三醇7-12份、氯化钠0.5-1.5份、羟基羧酸盐3-6份和水60-70份。本申请具有提高了对高碱水泥的助磨效果，优化了高碱水泥的粒径级配，促进了水化过程的进行，改善了水化产物的形貌，从而提高了高碱水泥的强度的效果。
