- Abstract
With zirconium oxychloride as the main body and glycerol/cocamidopropyl dimethylamine ethyl lactone as the ligand, a functional cross-linking agent CL・24 w 让h surface activity was obtained, and the synthesis of the product was proved by infrared spectroscopy・ The obtained CL-24 and hydrophobic associating polyacrylamide polymer GS25 form polymer gel, and it is found that it can realize "secondary crosslinking" in the process of crosslinking・ The microstructure and rheological properties of jelly were characterized by scanning electron microscope and rotary rheometer・ The results showed that the functional surfactant CL-24 and associative polymer formed a spatial network structure ・ After shearing for 1 h at 130 °C and 170 s 1, the viscosity in clear water 101 mPa • s, and that in 20 000 mg/L sodium chloride solution was 113 mPa • s,让 was found that the functional crosslinking agent CL-24 promoted the polymer gel to show excellent temperature and salt resistance. Through dynamic rheological frequency scanning and stress scanning, it was found that the polymer gel fluid formed showed elastic characteristics and obvious u secondary crosslinking" phenomenon.
