Superfine slag powder grinding aid and preparation method thereof
The invention discloses a superfine slag powder grinding aid and a preparation method thereof, and belongs to the technical field of grinding admixtures. The grinding aid is prepared from the following raw materials in parts by weight: 20 to 40 parts of small molecular polyether polyol, 10 to 20 parts of ethylene glycol and diethylene glycol mixed liquid, 5 to 10 parts of water glass, 0.1 to 0.5 part of hexadecyl sodium sulfonate, 0.1 to 0.5 part of a de-foaming agent and 20 to 40 parts of water. According to the invention, ethylene oxide and glycollic acid are adopted to synthesize the micromolecular polyether polyol oligomer, so that the micromolecular polyether polyol oligomer can adapt to slag with different particle sizes, realizes good adsorption and dispersion effects, effectively solves the problem of slag differential agglomeration in the superfine grinding process, and has a good grinding aiding effect on the slag. The obtained grinding aid can effectively improve the superfine grinding efficiency of the slag powder, shorten the superfine grinding time and improve the machine-hour yield by 20%.
本发明公开一种超细矿渣粉助磨剂及其制备方法，属于粉磨外加剂技术领域。本发明助磨剂，包括以下重量份的原料制备而成：小分子聚醚多元醇20‑40份、乙二醇和二甘醇混合液10‑20份、水玻璃5‑10份、十六烷基磺酸钠0.1‑0.5份、消泡剂0.1‑0.5份和水20‑40份。本发明采用环氧乙烷与乙醇酸合成小分子聚醚多元醇类低聚物，能够适应对不同颗粒尺寸的矿渣，实现良好的吸附分散作用，有效的解决超细粉磨过程中矿渣微分的团聚问题，对矿渣具有较好的助磨效果。所得助磨剂，能够有效提高矿渣粉超细粉磨的效率，缩短超细粉磨的时间，提高台时产量20%。
