Sulfamate water reducing agent and preparation method thereof
The invention relates to a sulfamate water reducing agent and a preparation method thereof. The sulfamate water reducing agent has a macromolecular network structure formed by copolymerization and cross-linking of sulfamate aromatic hydrocarbon, sodium sulfanilate, phenol and formaldehyde. According to the method, the characteristic that a sulfamate aromatic hydrocarbon mixture obtained by pre-treating dye intermediate sulfamate aromatic hydrocarbon production wastewater has a large number of hydrophilic groups such as amino groups, sulfonic groups and the like is fully utilized; and accordingto the production raw materials of a water reducing agent for sulfamate aromatic hydrocarbon mixture concrete, pollutants are properly treated and are turned into wealth, circular economy recycling is achieved, the pollutant treatment cost of an enterprise is reduced, and remarkable social benefits and economic benefits are achieved.
一种氨基磺酸盐类减水剂及其制备方法,所述氨基磺酸盐类减水剂具有由氨基芳烃磺酸盐、对氨基苯磺酸钠、苯酚及甲醛共聚交联形成的大分子网状结构。本发明充分利用了由染料中间体氨基芳烃磺酸盐的生产废水经预处理而获得的氨基芳烃磺酸盐混合物具有大量氨基、磺酸基等亲水基团的特性,将该氨基芳烃磺酸盐混合物混凝土用减水剂的生产原料,既实现了污染物妥善处置,使污染物变废为宝,实现了循环经济资源化,又降低了企业处置污染物的成本,具有显著的社会效益和经济效益。
