“…Therefore, the comprehensive action process of the above reasons results in the offset of the pyrolysis temperature. This conclusion is similar to that obtained by Pawlowski [1], Despinasse [2], Wawrzyn [12] and Feng [27] et al However, the action result of toughener on the pyrolysis temperature is contrary to the above conclusion.…”

“…The studies from Pawlowski et al [1] and Wawrzyn et al [12] showed that with the increase of the content of flame retardants, the thermal decomposition rate of composites reduces, the ratio of residual char of composites increases, and the flame behavior of composites is significantly restrained. Gui et al [15] found that the different flame retardants have their different works at different times.…”

In this study, standard test specimens with flameretarded short glass fiber-reinforced PC/ABS materials were fabricated under rapid thermal cycle injection molding condition by selecting a potassium perfluorobutane sulfonate flame retardant specially used for PC, FR2025, and two kinds of aryl phosphorus halogen-free flame retardants, UN707 and PX-220. The flame-retardancy effect of the above different flame retardants on the studied systems was compared through combustion tests of the specimens. Meanwhile, the thermal and mechanical properties of flame-retarded composites were studied by using the thermogravimetry analysis, dynamic mechanical thermal analysis (DMTA), and universal testing machine. The results show that the "candlewick effect" of fibers exacerbates the fire behavior of composites. With the increase of the aryl phosphorus halogen-free flame retardants, the flame-retardancy effect of composites is obviously improved, and the maximum thermal degradation rate of composites is significantly decreased. The UL94 combustion rating is improved, and the time of residual flame is substantially reduced with the increase of PC content under the same content of flame retardant. The DMTA results show that the flame retardants have a reinforcement action on PC/ABS matrix. However, the macroscopic mechanical properties are slightly decreased in the glass fiber-reinforced composites because of the destructive effect of the flame retardants on the interface compatibility between matrix and fibers; the scanning electron microscopic micrographs of tensile fracture fully prove this action mechanism of flame retardants. In addition, the addition of toughener and antidripping additive significantly affects the flame retardancy and mechanical properties of composites. POLYM. COMPOS., 00:000-000, 2014.

“…5 and 6. Among the samples, WF-ZB had the best smoke suppression properties compared with WF-25 and the COP of WF-ZB decreased by 49.16%, which suggested that the bubble structure char layer of IFR catalyzed by ZB played an important role in smoke suppression [48]. The WF-MMT sample had outstanding fire suppression performance, but its prolonged TTI resulted in a big smoke production rate peak during primary combustion, at the same time, the COP was relatively high because of incomplete combustion, and smoke suppression was the least of all samples.…”

“…Simultaneously, approaches have been made to combine different flame retardants or flame retardants with additives, respectively, and thus to obtain superior synergisms in flame retardancy [5][6]. Pawlowski et al studied flame retardancy of aryl phosphates in combination with boehmite (ALOOH) [7] and with zinc borate [8] in PC/ acrylonitrile-butadiene-styrene (ABS) blends. It was concluded that adding ALOOH can significantly enhance barrier effects of the fire residue during burning.…”

Abstract.The synergistic effects of methylphenyl-polsiloxane solid powder and organophosphate flame retardant for polycarbonate (PC) were investigated by limiting oxygen index(LOI), and cone calorimeter. It was found that the LOI of the flame-retarded PC (FR-PC) with polysiloxane and organophosphate binary flame retardants didn't increase in comparison with that of FR-PC containing a single species flame retardant. The cone calorimeter results show that the heat release rate (HRR) of the PC/polysiloxane/organophosphate(PX230) composition is approximately 50% lower than that of the PC/polysiloxane or the PC/PX230. Total heat release (THR) of PC/polysiloxane/PX230 also significantly reduce in comparison with that of PC/polysiloxane and PC/PX230 binary composites, which indicates a clear synergistic effect of the polysiloxane and PX230 in the PC flame retardant composites. The CO production rate of the PC/polysiloxane/PX230 during combustion is slightly lower than that of the virgin PC. So the combination of the polysiloxane with PX230 used in PC could synergic inhibit the combustion heat release, and achieve environmental friendly fire-retardant effect.
