Cement grinding aid and preparation method thereof
The invention discloses a cement grinding aid and a preparation method thereof. The cement grinding aid consists of the following substances: 3-5 parts of hyperbranched ethanolamine, 25-40 parts of synthetic polyester wastewater, 15-40 parts of sodium acetate, 2-5 parts of a surfactant and 15-30 parts of deionized water. The cement grinding aid provided by the invention does not contain volatile matters, has no toxic or side effect, and accords with relevant national and industrial standards. Meanwhile, the cement grinding aid can effectively guarantee smooth implementation of the grinding process, the phenomena of caking, blocking and the like in the grinding process are inhibited, and the ground material is smaller in particle size and larger in specific surface area. In addition, the high-efficiency cement grinding aid disclosed by the invention is helpful for improving the compressive strength and breaking strength of cement.
水泥助磨剂及其制备方法，由以下物质组成：超支化乙醇胺3‑5份，合成聚酯废水25‑40份，乙酸钠15‑40份，表面活性剂2‑5份，去离子水15‑30份。本发明的水泥助磨剂不含易挥发物，无毒副作用，符合国家和行业的相关标准。同时本发明水泥助磨剂，可以有效保证研磨工序的顺利进行，抑制研磨过程中的结块和堵塞等现象，并且研磨后物料粒径更小，比表面积更大。另外，本发明的高效水泥助磨剂有助于水泥抗压、抗折强度的提高。
