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 C3H6N6 modified 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 C3H6N6 in 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.

AbstractA DOPO (9,10-dihydro-9-oxa-10-phosphaphen-anthrene-10-oxide)-based halogen-free flame retardant (ODOPM-CYC) was synthesized and incorporated in rigid polyurethane foam (RPUF). The structure of ODOPM-CYC was characterized by Fourier transform infrared spectra (FTIR), 1H NMR and 31P NMR. The effects of ODOPM-CYC on the flame resistance, mechanical performances, thermal properties and cell structure of RPUF were also investigated. The results showed that the incorporation of ODOPM-CYC strikingly enhanced flame retardant properties of RPUF. The flame retarded RPUF acquired a limiting oxygen index (LOI) value of 26% and achieved UL-94 V-0 rating with the phosphorus content of 3 wt%. The smoke production rate (SPR) also showed an obvious decrease and total smoke release (TSR) was 39.8% lower than that of neat RPUF. Besides, the results demonstrated that the incorporation of ODOPM-CYC provided RPUF better thermal stability but did not show any obvious influence on its thermal conductivity.
