Efficient cement grinding aid and preparation method thereof
The invention belongs to the technical field of cement grinding aids, and particularly relates to an efficient cement grinding aid and a preparation method thereof.The efficient cement grinding aid is prepared from, by weight, 15%-30% of polyhydric alcohol compounds, 10%-15% of organic acid salt, 12%-20% of a surfactant, 10%-15% of a reinforcing agent and 0.3%-5% of a defoaming agent; the invention further discloses a preparation method of the efficient cement grinding aid. The preparation method comprises the following preparation steps: S1, raw material pretreatment; s2, mixing and dispersing; s3, preparing solid raw material spherical particles; s4, dissolving; s5, adding nano silicon dioxide and modified starch; and S6, post-processing. The cement grinding aid disclosed by the invention can be used for refining cement particles and optimizing particle composition, so that the specific surface area of cement is increased, the problems of caking of raw materials and non-uniform local concentration are effectively avoided, and the mixing effect is improved.
本发明属于水泥助磨剂技术领域，尤其涉及一种高效水泥助磨剂及其制备方法，其中一种高效水泥助磨剂，包括以下重量百分比的原料：多元醇类化合物15%～30%、有机酸盐10%～15%、表面活性剂12%～20%、增强剂10%～15%、消泡剂0.3%～5%；本发明还公开了一种高效水泥助磨剂的制备方法，包括以下制备步骤：S1、原料预处理；S2、混合与分散；S3制备固体原料球形颗粒；S4、溶解；S5添加纳米二氧化硅与改性淀粉；S6后处理。本发明的水泥助磨剂能够使水泥颗粒更加细化，优化了颗粒级配，从而提高了水泥的比表面积，有效避免了原料结块和局部浓度不均的问题，提高了混合效果。
