| Abstract: | Zinc borate （ZB） as a synergistic flame retardant was compounded with aluminum diethylhypophosphonate （ADP） for flame?retarding nylon 6. The flame retardant properties and mechanical properties of the resultant compounds were evaluated， and their flame retardant mechanism was investigated using vertical combustion， limiting oxygen index， cone calorimetry， thermogravimetric analysis， scanning electron microscopy and Raman spectroscopy. The results indicated that the synergistic flame?retardant effect resulting from ZB and ADP was remarkable. When 1.5 % Zb and 8.5 % ADP were added into PA6， obtained composites achieved a flame?retardant level classification of UL 94 V?0 with a limi?ting oxygen index of 29.8 vol % Compared to the samples without a synergistic agent， their peak heat release rate， average heat release rate， and mass loss rate decreased by 42.7 %， 27.3 % and 32.7 %， respectively. The cone calorimetry analysis indicated that the introduction of ZB into the ADP flame retardant system not only generated a flame?retardant effect of the vapor phase， but also promoted the flame retardancy of condensed phase. This was attributed to a synergistic flame retardant mechanism， mainly based on the gas?phase flame retardancy together with the condensed?phase flame retardancy |
