The invention belongs to the technical field of water reducing agents, and particularly relates to a preparation method of a sulfamic acid water reducing agent. The method comprises the following steps: 1, preparing a liquid water reducing agent: adding water, phenol, diaminobenzenesulfonic acid and urea into a reaction kettle, heating, adding formaldehyde, stirring, adding an alkaline regulator and triethanolamine, and continuously stirring and cooling to obtain a sulfamic acid series liquid water reducing agent; 2, preparing a powder water reducing agent: heating the liquid water reducing agent to obtain a powder water reducing agent; and 3, bagging, sealing and storing: bagging and sealing the powder water reducing agent, and transferring to a shady and dry place for storing, wherein the process of bagging the sulfamic acid series powder water reducing agent in the step 3 is completed by adopting a sulfamic acid series water reducing agent preparation device in a matching manner. Bymeans of the discharging mechanism, it can be guaranteed that the discharging amount is constant each time, it is guaranteed that powder cannot leak from the sealing barrel and the bag opening whilethe bagging efficiency is improved, and the uniformity of the charging amount is further improved.
本发明属于减水剂技术领域，具体涉及一种氨基磺酸系减水剂的制备方法，包括如下步骤：步骤一、制备液体减水剂：在反应釜中加入水、苯酚、二氨基苯磺酸和尿素,加热后加入甲醛,搅拌后加入碱性调节剂和三乙醇胺,继续搅拌冷却后得到氨基磺酸系液体减水剂；步骤二、制备粉体减水剂：对液体减水剂加热，得到粉体减水剂；步骤三、装袋密封保存：对粉体减水剂进行装袋密封，转运至背阴干燥处保存；其中，步骤三对氨基磺酸系粉体减水剂进行装袋的过程采用一种氨基磺酸系减水剂制备装置配合完成。本发明的卸料机构能够保证每次卸料量恒定，本发明提高了装袋效率的同时保证了粉末不会从密封筒和袋口处泄露，进一步提高了装料量的均匀度。
