4-tert-butylcalix [4] arene modified polycarboxylate superplasticizer and preparation method thereof
The invention discloses a 4-tert-butyl calix [4] arene modified polycarboxylate superplasticizer, which is prepared by copolymerizing unsaturated carboxylic acid monomers, polyether macromonomers and 4-tert-butyl calix [4] arene modified polyether macromonomers as main raw materials. By grafting the 4-tert-butylcalix [4] arene on the side chain of the polycarboxylate superplasticizer, intercalation adsorption of montmorillonite and the like on a long-chain branch chain can be effectively prevented, so that the polycarboxylate superplasticizer shows excellent mud resistance and neat paste flow retention characteristic; and the related preparation method is relatively simple and is suitable for popularization and application.
本发明公开了一种4‑叔丁基杯[4]芳烃改性聚羧酸减水剂，它以不饱和羧酸单体、聚醚大单体和4‑叔丁基杯[4]芳烃改性聚醚大单体为主要原料进行共聚而成；本发明通过在聚羧酸减水剂侧链上接枝4‑叔丁基杯[4]芳烃，能有效防止蒙脱土等对长支链的插层吸附，进而表现出优异的抗泥性和净浆流动保持特性；且涉及的制备方法较简单，适合推广应用。
