| Abstract: | In the experiment,the anionic aqueous polyurethane modified by amino-silicone oil was synthesized by poly propylene carbonate glycol,IPDI,DMPA and self-made amino-silicone oil,which is a kind of textile finishing agent.The best synthesis conditions are as follows：pre-polymerization reaction is conducted under 80℃ for 2h or so,chain extension reaction is performed under 70℃ for 3~4h,amino silicone oil modification reaction is operated under 10 ℃ for 50min.The results show that the self-made anionic aqueous polyurethane modified by amino-silicone oil has small size,good stability,and the water resistance of film has significant improvement.The self-made textile finishing agent can meet the need of the basic industrial application,so this emulsion can be used in factory. |
