The Study of Melamine Modified by Imidazolium Based Ionic Liquid [BMIM]PF₆ on the Flame Retardancy of Rigid Polyurethane Foam

Abstract:

In this paper, the effect of C₃H₆N₆modified by imidazolium based Ionic Liquid 1-butyl-methylimidazolium hexafluorophosphate ([BMIM]PF₆) on polyurethane rigid foam flame retardant properties was conducted.The results show that the flame retardant properties of C₃H₆N₆modified with Ionic Liquid significantly increased and the LOI increased form 22.3 to 24.5. In the modification process, the ionic liquid mass have a very noticeable effect to the flame retardant property and when [BMIM]PF₆ and C₃H₆N₆in quality was 4:6, Fire-retardant effect was best.Compared with the prior to the modification, C₃H₆N₆ modified can increase effective Flame resistance of materials, horizontal burning speed from 67.6mm/min down to 33.4mm/min.Thermal degradation data show that C₃H₆N₆ modified could improve initial decomposition temperature and reminder yield of rigid polyurethane foam,and then heat release reduced, the decomposition controlled,thermal stability increased.
