Cement grinding aid and preparation method thereof
The invention relates to the technical field of building materials, in particular to a cement grinding aid and a preparation method thereof. The invention discloses a cement grinding aid. The raw materials comprise the following components in percentage by weight: 1-2 wt% of sucrose or white granulated sugar, 1-2 wt% of sodium lignin sulfonate, 5-10 wt% of triethanolamine, 2-3 wt% of triisopropanolamine, 2-3 wt% of ethylene glycol, 2-4 wt% of amino trimethylene phosphoric acid, 10-20 wt% of sodium thiosulfate, 5-10 wt% of calcium chloride and the balance water. According to the invention, theretarder and the grinding aid enhancer are organically combined together, so that the accuracy is improved, the intermiscibility of the retarder and the grinding aid enhancer is solved, and the manufacturing cost of cement enterprises is reduced. The requirement of the downstream industry for cement performance is satisfied. A set of metering equipment is used in cement production, and good economic benefits and social benefits are created.
本发明涉及建筑材料技术领域，具体涉及一种水泥助磨剂及其制备方法。所述水泥助磨剂，原料包括以下百分数的组分：蔗糖或白砂糖1wt％～2wt％、木质素磺酸钠1wt％～2wt％、三乙醇胺5wt％～10wt％、三异丙醇胺2wt％～3wt％、乙二醇2wt％～3wt％、氨基三亚甲基磷酸2wt％～4wt％、硫代硫酸钠10wt％～20wt％、氯化钙5wt％～10wt％、余量为水。本发明将缓凝剂与助磨增强剂有机的结合在一起，提高了精确度，解决了缓凝与助磨增强剂的相溶性，降低了水泥企业的制造成本。解决了下游产业对水泥性能的要求，在水泥生产中使用一套计量设备，创造了良好的经济效益和社会效益。
