Preparation method of mud-resistant concrete water reducing agent
The invention belongs to the technical field of water reducing agent processing, and particularly relates to a preparation method of a mud-resistant concrete water reducing agent. The method comprises the following steps: 1, carrying out polymerization reaction on a polyether monomer and an unsaturated monocarboxylic acid monomer in a tank body of synergistic treatment equipment under the action of an initiator and a chain transfer agent; 2, horizontally stirring the materials by using a stirrer to mix the materials; 3, the materials are vertically stirred through a stirrer, and the materials are further mixed; and 4, providing a temperature required by material polymerization through a heating table arranged in the tank body, and adjusting the pH value to 6-7 to obtain the mud-resistant polycarboxylic acid water reducer. The mud-resistant concrete water reducing agent is prepared from the following components: 4-hydroxybutyl vinyl polyoxyethylene polyoxybutylene ether, 4-hydroxybutyl vinyl ether, acrylic acid, methacrylic acid, sodium acrylate, methyl methacrylate, ammonium persulfate, sodium persulfate, mercaptoacetic acid and mercaptoethanol.
本发明属于减水剂加工技术领域，具体而言，是一种阻泥型混凝土减水剂制备方法；该方法采用以下步骤：步骤一：将聚醚单体和不饱和一元羧酸单体在引发剂和链转移剂的作用下，在增效处理设备中的罐体内进行聚合反应；步骤二：利用搅拌器对物料进行水平搅动，使其混合；步骤三：利用搅拌器对物料进行竖向搅动，对物料进一步混合；步骤四：通过罐体内置的加热台，提供物料聚合所需温度，调节PH值在6～7区间内，得到本品的阻泥型聚羧酸减水剂；该阻泥型混凝土减水剂的组成包括：4‑羟丁基乙烯基聚氧乙烯聚氧丁烯醚、4‑羟丁基乙烯基醚、丙烯酸、甲基丙烯酸、丙烯酸钠、甲基丙烯酸甲酯、过硫酸铵、过硫酸钠、巯基乙酸和巯基乙醇。
