Synthesis of Hydroxyl-Modified Amino Silicone Oil and Preparation of Cationic PAN Precursor Oil Agents
The amino-terminated silicone oil was quaternized by 2-chloroethoxyethanol,and the oil agents of polyacrylonitrile(PAN)carbon fiber precursor were prepared by the mechanical emulsification.By adjusting the contents of emulsifier and the speeds of emulsifying machine,the optimum experimental parameters were obtained.The results show that when the ratio of hydroxyl-modified amino silicone oil to OP-10 is 3∶4,and the emulsification speed is 3000 r/min,the particle sizes and polydispersity index(PDI)of the prepared oil agent are the best.The resulting emulsion droplets are uniform,and the thermal stability and centrifugal stability of the oil agent are good.
