The invention discloses a polycarboxylic acid high-performance water reducing agent and a production method, the water reducing agent comprises the following main components: acrylic acid, sodium methallyl sulfonate, maleic anhydride, an initiator, a reducing agent, a chain transfer agent, a defoaming agent, liquid caustic soda and water, and the initiator is made of ammonium persulfate. Through ammonium persulfate, sodium hydrogen sulfite, sodium hypophosphite and organic silicon, the efficient stability of the water reducing agent can be effectively improved, the situation of large-area slump is prevented, meanwhile, through arrangement of nitrate, the service life of the water reducing agent can be effectively prolonged, the rejection rate of the water reducing agent is reduced, the water reducing agent is more efficient, and the service life of the water reducing agent is prolonged. The problems that most water reducing agents in the market are not efficient and stable enough, deviation is prone to occurring in the using process, the performance of the water reducing agents is greatly reduced due to the influences of the environment, the temperature and the like, the slump loss is large, the using rate of the water reducing agents is reduced, and the using requirements of production personnel cannot be met are solved.
本发明公开了一种聚羧酸高性能减水剂及生产方法，所述减水剂的主要成分为：丙烯酸、甲基丙烯磺酸钠、马来酸酐、引发剂、还原剂、链转移剂、消泡剂、液碱和水，所述引发剂的材质为过硫酸铵。本发明通过过硫酸铵、亚硫酸氢钠、次亚磷酸钠和有机硅，能够有效增加减水剂的高效稳定性能，防止出现大面积坍落的情况，同时通过硝酸盐的设置，能够有效增加减水剂的使用寿命，使减水剂的报废率降低，使减水剂更加高效，解决了现有市面上大多数的减水剂不够高效稳定，在使用过程中容易出现偏差，通过环境、温度等影响会导致减水剂的性能大大降低，且坍落度损失较大，使减水剂的使用率降低，无法满足生产人员的使用需求的问题。
