The invention relates to a preparation method of a solid concrete water reducing agent. The preparation method comprises the following steps: weighing calcium chloride, calcium sulfate, calcium hydroxide, sodium sulfate, potassium sulfate, phosphorus pentoxide and sodium nitrate, uniformly mixing to obtain a mixture A; adding acetic acid, ethanol, hydrogen peroxide and deionized water into a container, uniformly mixing to obtain a mixed solution B; adding the mixed solution B into the mixture A, uniformly stirring to obtain a mixture C; adding the mixture C into a closed container, heating toa reflux state, carrying out spray drying to obtain water reducing agent particles; and grinding the water reducing agent particles into powder to obtain the solid concrete water reducing agent. The production process of the water reducing agent is improved, the generated heat during the preparation process is reduced, the production safety coefficient is increased, and the water reducing effect of the water reducing agent is enhanced at the same time, such that the use amount of the water reducing agent is reduced, and the cost is reasonably saved.
本发明涉及一种固态混凝土减水剂的制备方法，通过以下步骤制备混凝土减水剂：称取氯化钙、硫酸钙、氢氧化钙、硫酸钠、硫酸钾、五氧化二磷和硝酸钠混合均匀，得到混合物A；将乙酸、乙醇、双氧水和去离子水置于容器中混合均匀，得到混合溶液B；将混合溶液B加入混合物A中，搅拌均匀，得到混合物C；将混合物C置于封闭容器内加热至回流状态，喷雾干燥，得到减水剂颗粒；将减水剂颗粒研磨成粉即得到固态混凝土减水剂。本发明改良了该减水剂的生产工艺，减少了制备过程中得产热量，增加了生产的安全系数，同时增强了减水剂的减水效果，进而减少了减水剂的使用量，合理的节约了成本。
