Thermal properties of polycarbonate containing potassium perfluorobutane sulfonate
international conference on mechatronics(2016)
摘要
Potassium perfluorobutane sulfonate (PPFBS) was used to impart flame retardancy to polycarbonate (PC). The thermal properties of of the PC/PPFBS composites were studied by limiting oxygen index (LOI), vertical burning test (UL-94), TG, and scanning electron microscopy (SEM). The results showed that PC/1wt.% PPFBS composites passed UL-94V-0 rating, and its LOI values were 30.6%. Compared with PC, for the PC/PPFBS composites, the thermal stability and the char yield are increased. Scanning electron microscopy revealed that the char properties had crucial effects on the flame retardancy.
