Abstract
The invention discloses a preparation method of an efficient water reducer for sulfamate. The method comprises the following steps: weighing quantitative water, placing in an insulating flask, adding sodium hydroxide and uniformly stirring; adding quantitative sulfanilic acid and phenol; and dropping a formaldehyde liquor, and detecting to obtain a finished product. According to the preparation method disclosed by the invention, the efficient water reducer for sulfamate is produced by a method without a heat resource by means of reaction heat. The product has the characteristics of high water reducing efficiency, low energy consumption and high production efficiency, and the problem that existing efficient water reducers for sulfamate in production are long in production period and high in energy consumption and do not meet the demand of energy conservation and emission reduction and sustainable development is better solved. In addition, the preparation method disclosed by the invention is convenient to operate and low in using cost, the production cost is lowered, and the preparation method has good application value.
