摘要
A flame retardant （DPA-SiN） containing phosphorus, nitrogen and silicon elements was synthesized. The halogen free flame retardant was incorporated into PC/ABS to improve its flame retardancy. The flame-retardant properties of the PC/ABS/DPA-SiN blends were estimated by limiting oxygen index （LOI） values and CONE Calorimeter, while thermal stabilities were investi- gated through thermo gvavimetric analysis （TGA）. The PC/ABS/DPA-SiN blends were thermally degraded at 400℃ for different amounts of time and studied by Fourier transform infrared spectroscopy （FTIR） to better understand the degradation behavior of PC/ABS/DPA-SiN.
