Polycarboxylate gypsum water reducing agent and preparation method and application thereof
The invention discloses a polycarboxylate gypsum water reducing agent and a preparation method and application thereof. The polycarboxylic acid gypsum water reducing agent is prepared from the following raw materials: polyoxyethylene ether, acrylic acid, methacrylic acid, sodium methallyl sulfonate, 2-acrylamide -2-methyl propanesulfonic acid, an initiator, a molecular weight regulator, a pH regulator, deionized water and nanoscale inorganic particles. The polycarboxylic acid gypsum water reducing agent has a certain water reducing rate and can effectively shorten the gypsum setting time.
本发明公开了一种聚羧酸石膏减水剂及其制备方法和应用。聚羧酸石膏减水剂的制备原料包括：聚氧乙烯醚、丙烯酸、甲基丙烯酸、甲基丙烯磺酸钠、2‑丙烯酰胺‑2‑甲基丙磺酸、引发剂、分子量调节剂、pH调节剂、去离子水和纳米级无机颗粒。本发明的聚羧酸石膏减水剂既具有一定的减水率又能有效缩短石膏凝结时间。
