Effects of hexaphenoxycyclotriphosphazene and glass fiber on flame‐retardant and mechanical properties of the rigid polyurethane foam

AbstractThe present study emphasizes the reinforcement of rigid polyurethane foam (RPUF) by the addition of glass fibers (GFs) for diverse engineering applications. In contrast to the conventional RPUF, the foam developed in this case is castor oil based. The developed reinforced foam was tested for its mechanical properties such as hardness, tensile, flexural and compressive strength and for its morphology. Mechanical properties of the resulted reinforced RPUF were found to be improved with addition of the GF content. The foam density was also observed to be increased with the insertion of GF. The SEM results clearly indicated the decreased cell size in the reinforced RPUF.

The Impact

A novel Flame-Retardant N-(P,P′-diphenyl) phosphorus-based-(3-triethoxysilicon) propylamine (DPTP) was synthesized in this study. The impact of DPTP on the mechanical properties, thermal stability, and flame retardancy of rigid polyurethane foam (RPUF) was studied. The addition of DPTP to RPUF can significantly reduce the undesirable thermal effects and smoke density during combustion, as well as increasing the limiting oxygen index. Compared with pure RPUF, the peak heat release rate of RPUF containing 10 phr of DPTP decreased by 39.4%, while its peak smoke production rate decreased by 49.9%. However, it was also found that the addition of DPTP reduced the compressive strength of RPUF.

Flame Retardant Properties

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.
