The invention discloses a preparation method of a cement synergist, and the cement synergist comprises the following raw material components in parts by weight: 18-22 parts of a self-made additive, 3-6 parts of a surfactant, 2.5-6 parts of a dispersant, 14-18 parts of modified diatomite, 5-10 parts of polyacrylamide and 7-12 parts of hydroxypropyl methyl cellulose. The preparation method comprises the following steps: sequentially weighing the raw materials in parts by weight; uniformly mixing the self-made additive with the modified diatomite, and then sequentially adding the dispersing agent, the active surface agent polyacrylamide and the hydroxypropyl methyl cellulose, and mixing all the components to obtain the cement synergist.
本发明公开了一种水泥增效剂的制备方法，所述水泥增效剂按重量份数计，包括以下原料成分：自制添加剂18～22份、表面活性剂3～6份、分散剂2.5～6份、改性硅藻土14～18份、聚丙烯酰胺5～10份和羧丙基甲基纤维素7～12份；所述制备方法包括以下步骤：按重量份数计依次称取上述原料；将自制添加剂与改性硅藻土混合均匀，然后依次加入分散剂、活性表面剂聚丙烯酰胺和羧丙基甲基纤维素混合得到水泥增效剂。
