Cement grinding aid and preparation method thereof
The invention discloses a cement grinding aid and a preparation method thereof, and the cement grinding aid is mainly prepared from a silane coupling agent, isopropanol, chitosan, ammonium chloride, ethylene glycol, calcium stearate, stearic acid, triethanolamine, fatty alcohol polyoxyethylene ether sodium sulfate, hexadecanol and deionized water. Compared with the prior art, the preparation method of the cement grinding aid is simple, no waste water or waste residues are generated in the preparation process, only a small amount of organic waste gas is generated, and the cement grinding aid is more environmentally friendly; the prepared cement grinding aid is small in mixing amount, the specific surface area of cement particles can be remarkably increased, the defect that agglomeration and condensation are not solid is greatly reduced, and the compressive strength and early strength of cement are improved.
本发明公开了一种水泥助磨剂及其制备方法，该水泥助磨剂，主要由硅烷偶联剂、异丙醇、壳聚糖、氯化铵、乙二醇、硬脂酸钙、硬脂酸、三乙醇胺、脂肪醇聚氧乙烯醚硫酸钠、十六醇和去离子水制成。相比现有技术，该水泥助磨剂制备方法简单，且制备过程中无废水、废渣产生，仅产生少量有机废气，更环保；制备的水泥助磨剂掺量少，可显著增加水泥颗粒比表面积，大大降低了团聚凝结不实的缺陷，改善了水泥的抗压强度和早期强度。
