Preparation method of early-strength polycarboxylic acid high-performance water reducing agent
The invention belongs to the field of preparation of water reducing agents, and particularly relates to a preparation method of an early-strength polycarboxylic acid high-performance water reducing agent. Aiming at problems that reactors are inconvenient to cool quickly and preheat is inconvenient to recover during preparation of water reducing agents in the prior art, a technical scheme is provided, wherein the method includes steps that: S1, a copper pipe is wound around the outer side of a preheating container, one end of the copper pipe is communicated with a reactor, the other end of thecopper pipe is connected with an exhaust hood, a transmission shaft is arranged in the exhaust hood, and fan blades are installed on the transmission shaft; S2, a cooling pipe is wound on the outer side of the reactor, one end of the cooling pipe is connected with a water source, and the other end of the cooling pipe is provided with a valve; S3, unsaturated polyoxyethylene ether and an emulsifierare added into the preheating container, and then weighed. According to the method, the reactor can be rapidly cooled, meanwhile, preheating can be utilized, and the production efficiency is improved.
本发明属于减水剂的制备领域，尤其是一种早强型聚羧酸高性能减水剂的制备方法，针对现有的在制备减水剂时，不便于快速对反应器进行冷却，同时不便于对预热进行回收利于的问题，现提出如下方案，其包括以下步骤：S1：将铜管盘绕在预热容器的外侧，铜管的一端与反应器连通，铜管的另一端连接一个抽气罩，抽气罩内设一个传动轴，传动轴上安装扇叶；S2：将冷却管盘绕在反应器的外侧，冷却管的一端接头水源，冷却管的另一端设一个阀门，S3：将不饱和聚氧乙烯醚、乳化剂放进预热容器内，然后对不饱和聚氧乙烯醚、乳化剂进行称量，本发明可以使反应器快速冷却，同时可以对预热进行利用，提高生产效率。
