The invention belongs to the technical field of preparation of water reducing agents, and particularly relates to a preparation method of an environment-friendly self-corrosion-resistant polycarboxylic acid water reducing agent. The preparation method comprises the following steps: S1, raw material preparation: sequentially weighing the following raw materials in parts by weight: 15 to 19 parts of sodium methallyl sulfonate, 11 to 15 parts of diethylenetriamine, 6 to 10 parts of graphene oxide, 12 to 16 parts of methyl allyl polyoxyethylene ether, 8 to 12 parts of itaconic acid, 4 to 8 parts of hydrogen peroxide, 19 to 23 parts of thiohydracrylic acid, 21 to 25 parts of potassium carbonate and 10 to 14 parts of water; S2, preparing of a base solution: adding the sodium methallyl sulfonate, the diethylenetriamine and the water in the S1 into a reaction kettle, and conducting stirring and heating until the sodium methallyl sulfonate, the diethylenetriamine and the water are dissolved to obtain the base solution; and S3, preparing a mixed solution. The preparation steps of the water reducer are simple and convenient, the anti-corrosion and antibacterial properties of the water reducer are effectively improved, the workability of the water reducer is improved, and the slurry backflow phenomenon is not serious.
本发明属于减水剂制作技术领域，尤其为一种环保自防腐型聚羧酸减水剂的制备方法，其制备方法包括以下步骤：S1：原料准备：按以下重量份依次称取原材料：甲基丙烯磺酸钠15‑19份、二乙烯三胺11‑15份、氧化石墨烯6‑10份、甲基烯丙基聚氧乙烯醚12‑16份、衣康酸8‑12份、双氧水4‑8份、巯基丙酸19‑23份、碳酸钾21‑25份和水10‑14份；S2：底液配制：将S1中所述的甲基丙烯磺酸钠、二乙烯三胺和水加入到反应釜中，搅拌加热直至溶解，得到底液；S3：配制混合液。本发明减水剂制备步骤简单便捷，有效的提高减水剂防腐抗菌性能，并且提高减水剂的和易性，反浆现象不严重。
