Mud-resistant slump-retaining water reducing agent and preparation method thereof
The invention relates to the technical field of concrete additive synthesis, and particularly discloses a mud-resistant slump-retaining type water reducing agent and a preparation method thereof.The preparation method comprises the following steps that 300-400 parts of polyether monomers, 250-350 parts of water, 1-3 parts of ammonium persulfate, 40-60 parts of H8, 1-3 parts of Cj-01, 10-30 parts of liquid A and 50-80 parts of liquid B are added into a reactor tank for a reaction, a stirring shaft is arranged in the reactor tank for stirring, and a mixture is obtained; a liquid dropping tank is arranged at the top end of the reaction tank, a dropping pipette is downwards and obliquely arranged at the bottom end of the liquid dropping tank, the dropping pipette is communicated with a liquid feeding pipe, the liquid feeding pipe extends into the bottom end of the reaction tank, an air pump is fixedly connected to the top end of the liquid feeding pipe, and the liquid feeding pipe extends into the bottom end of the reaction tank. Liquid drops flowing out of the bottom end of the reaction tank are diffused to the upper part of the reaction tank and are in full contact with reactants in the reaction tank for rapid reaction, so that the situation that dropwise added liquid gathers in the liquid feeding pipe and cannot fully react to generate byproducts is avoided.
本申请涉及混凝土添加剂合成技术领域，具体公开了一种抗泥保坍型减水剂及其制备方法，其包括如下步骤：将聚醚单体300‑400份、水250‑350份，过硫酸铵1‑3份、H8 40‑60份、Cj‑01 1‑3份、A液10‑30份、B液50‑80份加入反应器罐中反应，反应罐中设有搅拌轴用于搅拌，反应罐顶端设有液体滴加罐，液体滴加罐底端向下倾斜设有滴液管，滴液管连通有送液管，送液管延伸进反应罐底端，送液管顶端固定连接有气泵，送液管延伸进反应罐底端，固液滴直接送到反应罐底端，再经过气压压缩，流出反应罐底端的液滴往反应罐上部扩散，与反应罐中的反应物全面接触快速反应，避免滴加液在送液管内聚集无法充分反应产生副产物。
