Efficient cement grinding aid and preparation method thereof
The invention discloses an efficient cement grinding aid comprising modified polymeric alkylol amine, molasses, sodium lignin sulfonate, industrial salt and water, including 5-15 percent of modified polymeric alcohol amine, 8-12 percent of polyamide fiber, 1-3 percent of sodium lignin sulfonate, 2-13 percent of industrial salt and 25-70 percent of water. The invention relates to a product preparedby mixing a brand-new polymeric alcohol amine material with other functional materials. The defects that a traditional cement grinding aid is low in grinding efficiency, poor in applicability, high in cost and not obvious in cement strength improvement are overcome from the molecular structure; meanwhile, macromolecular alcohol amine molecules in the novel polymeric alcohol amine type efficient cement grinding aid have a distinct improvement effect on enhancing and exciting the early and later strength of cement, the later strength of the cement has no shrinkage phenomenon, and the defect that the strength of the cement can only be improved by increasing the mixing amount of the traditional grinding aid is overcome.
本发明公开了一种高效水泥助磨剂，包括改性聚合醇胺、糖蜜、木质素磺酸钠、工业盐和水，其中所述改性聚合醇胺占比设为5‑15％，所述棉纶纤维占比设为8‑12％，所述木质素磺酸钠占比设为1‑3％，所述工业盐占比设为2‑13％，所述水的占比设为25‑70％。本发明是一种全新的聚合醇胺材料与其他功能材料混合后制备的产品，从分子结构上克服了传统水泥助磨剂的粉磨效率低、适用性差、成本高、对水泥强度提升不明显的缺点，同时这种新型聚合醇胺类的高效水泥助磨剂中的高分子醇胺分子对增强激发水泥早后期强度有明现的提升效果，水泥后期强度无倒缩现象，克服了传统助磨剂只能通过增加掺量来改善水泥强度的缺点。
