- A novel self-intumescent flame retardant of branched polyphosphoramide (BPCDC), was synthesized by the solution polymerization. The chemical structure of BPCDC has been demonstrated by fourier transform infrared spectroscopy (FTIR), and the flame-retardant properties of EP/BPCDC composites was investigated by vertical burning (UL-94), limiting oxygen index (LOI), and the cone calorimeter (CONE) test. The results rereveal that the BPCDC could effectively improve the flame-retardant performance of EP, When the 15 wt % BPCDC loading, the EP composite reached an LOI value of 32.9 % and a V-0 rating in the UL-94 test, and the peak of heat release rate and total heat release value was decreased by 54.8 % and 42.7%, respectively. The flame retardancy properties of EP/BPCDC composites with APP was also investigated, and the test results rereveal that BPCDC have a synergistic effect with APP in flame-retardant epoxy resins.
