The invention discloses a preparation method of a polycarboxylate superplasticizer with multi-layer side chain length. The method comprises the following steps: adding a substrate for synthesizing a polycarboxylate superplasticizer into a reaction kettle, and uniformly stirring the substrate; and preparing a mixture A and a mixture B. According to the preparation method of a polycarboxylate superplasticizer with multi-layer side chain length, the polycarboxylate superplasticizer with multi-layer side chain length is synthesized in the reaction kettle through free radical polymerization of an aqueous solution; the process is simple, no complex operating procedure is provided, aqueous solution free radical polymerization is easily carried out in a reaction kettle industrially; the steric effect after a polycarboxylic acid molecular chain is combined with cement molecules can be improved, so that a good dispersion effect is provided and the superplasticizer has high water reducing efficiency. Compared with a common water reducing agent, the polycarboxylate superplasticizer has the advantages that the production cost is lower, the preparation process is simple and convenient, no redundant production cost is generated, and the economic benefit is higher.
本发明公开了一种含有多层次侧链长度的聚羧酸减水剂的制备方法，包括以下步骤：将合成聚羧酸减水剂的底物添加到反应釜，并且将底物搅拌均匀；配置混合物A和混合物B。本发明所述的一种含有多层次侧链长度的聚羧酸减水剂的制备方法，通过水溶液自由基聚合在反应釜中合成了含有多层次侧链长度的聚羧酸减水剂，过程简单，无复杂的操作程序，易于工业化通过在反应釜中进行水溶液自由基聚合，能够增加聚羧酸分子链与水泥分子结合后的位阻效应，因而具有更好的分散效果，使得本减水剂能够具有更高的减水效率，相比于普通的减水剂，其本发明所制备的产物生产成本更低，并且制备过程简便，无多余的生产成本，具有较高的经济效益。
