The invention discloses a preparation method of a high-strength waterproof cement reinforcing agent, and belongs to the technical field of cement additive preparation. The preparation method comprisesthe following steps: firstly, grinding and mixing montmorillonite and hematite, adding the obtained mixture into distilled water, adding bagasse, heating to obtain a mixed solution, adding an alkaliliquor into the mixed solution, stirring, filtering after the stirring to obtain a reaction product, mixing the reaction product with water, adding sodium hypochlorite, mixing and reacting to obtain an oxidation reaction solution, carrying out high-temperature and high-pressure treatment on the oxidation reaction solution, adjusting the pH value, reacting to obtain a prefabricated solution, concentrating and drying the prefabricated solution, carrying out high-temperature treatment to obtain a thermal reactant, crushing and grinding the thermal reactant, montmorillonite and other raw materials, adding sodium metasilicate and methyl hydroxyethyl cellulose ether, and uniformly mixing to obtain the high-strength waterproof cement reinforcing agent. The cement reinforcing agent can enhance mechanical properties and waterproof properties of cement and enhance the wear resistance of cement.
本发明公开了一种高强度防水型水泥增强剂的制备方法，属于水泥助剂制备技术领域。本发明首先将蒙脱土和赤铁矿石研磨混合，投入蒸馏水中加入甘蔗渣加热制得混合液，向混合液中加入碱液搅拌，搅拌后过滤得到反应产物，随后将反应产物和水混合，再加入次氯酸钠混合反应制得氧化反应液，将氧化反应液进行高温高压处理，调节pH值后反应制得预制溶液，然后将预制溶液浓缩干燥，高温处理制得热反应物，最后将热反应物、蒙脱石以及其它原料粉碎研磨，再加入偏硅酸钠、甲基羟乙基纤维素醚混合均匀即得高强度防水型水泥增强剂，增强水泥的力学性能和防水性能，提高水泥的耐磨性能。
