Preparation process of cement water reducing agent
The invention relates to the field of water reducing agents, in particular to a preparation process of a cement water reducing agent. The process comprises the following steps: step 1, taking water as a base solution, adding sodium sulfanilate and phenol into the base solution, and heating and stirring to obtain a solution A; 2, adding formaldehyde and caustic soda liquid into the solution A, and stirring at constant temperature to obtain a solution B; and 3, condensing the solution B, cooling and stirring to obtain the water reducing agent. The preparation process of the cement water reducing agent also uses a preparation device of the cement water reducing agent, and the device comprises a conical barrel, a special-shaped barrel fixedly connected to the conical barrel, two feeding pipes fixedly connected to the conical barrel, and two supplementing pipes fixedly connected to the special-shaped barrel. The device has the advantage that the feeding dispersion effect of the water reducing agent raw materials can be enhanced.
本发明涉及减水剂领域，更具体的说是一种水泥减水剂制备工艺。该工艺包括以下步骤：步骤一：以水为基液向其中添加对氨基苯磺酸钠和苯酚，并进行升温搅拌得到溶液A；步骤二：向溶液A中添加甲醛和液碱，进行恒温搅拌得到溶液B；步骤三：对溶液B进行缩合后，进行降温搅拌得到减水剂。所述水泥减水剂制备工艺还使用一种水泥减水剂制备装置，该装置包括锥形桶，以及固接在锥形桶上的异形桶，以及固接在锥形桶上的两个加料管，以及固接在异形桶上的两个补料管。具有能够加强减水剂原料进料分散效果的优点。
