The invention discloses cement containing a cement grinding aid. The cement grinding aid is prepared from the following raw materials in parts by weight: 50-60 parts of a water-based polyhydroxy copolymer and 30-40 parts of modified hyperbranched polyethyleneimine. The invention also discloses a preparation method of the cement grinding aid, which comprises the following steps: proportionally anduniformly mixing raw materials, and grinding to obtain cement grinding aid. The cement grinding aid disclosed by the invention has the advantages of being low in production cost, low in mixing amount,capable of effectively improving the lubricity and the like of cement and the machine-hour yield, remarkable in grinding aid enhancing effect, and safe and environment-friendly to use.
本发明公开了一种含水泥助磨剂的水泥，其水泥助磨剂由如下重量份的原料制成：水性多羟基共聚物50‑60份、改性超支化聚乙烯亚胺30‑40份。本发明还公开了所述水泥助磨剂的制备方法，包括如下步骤：将各原料按比例混合均匀，后经过碾磨，得到水泥助磨剂。本发明公开的水泥助磨剂具有生产成本低廉，掺量低，能有效改善水泥的润滑性等性能和台时产量，助磨增强效果显著，使用安全环保的优点。
