Early strength cement grinding aid and preparation method thereof
The invention relates to the field of cement grinding aids, and particularly discloses an early strength cement grinding aid and a preparation method thereof. The early strength cement grinding aid is prepared from the following raw materials in parts by weight: 20 to 40 parts of triethanolamine, 5 to 12 parts of cyclodextrin, 15 to 30 parts of organic acid and 1 to 10 parts of alcohol compound. The preparation method comprises the following steps: S1, uniformly mixing triethanolamine and an alcohol compound to prepare a mixture; and S2, adding cyclodextrin and organic acid into the mixture, and uniformly mixing to obtain the early strength cement grinding aid. According to the invention, the problem of cement efflorescence is solved while the early strength of the cement is enhanced; in addition, the preparation method has the advantage of being easy to operate.
本申请涉及水泥助磨剂领域，具体公开了一种早强水泥助磨剂及其制备方法。早强水泥助磨剂，原料按重量份计，包括三乙醇胺20‑40份、环糊精5‑12份、有机酸15‑30份、醇类化合物1‑10份；其制备方法为：S1、将三乙醇胺、醇类化合物混合均匀制得混合料；S2、向混合料中投入环糊精、有机酸并混合均匀制得早强水泥助磨剂。本申请在增强水泥的早期强度的同时解决了水泥泛碱的问题；另外，本申请的制备方法具有操作简单的优点。
