Effect of a novel phosphorus and silicon system on flame retardancy and thermal degradation of PC

摘要：

　　The novel phosphine was used with a silicon resin to impart flame resistancy to polycarbonate.Combustion behaviors and thermal degradation properties of flame retardancy PC have been assayed by limiting oxygen index,vertical burning test and thermogravimetric analysis.Dynamic rheological of FR-PC was also examined.Flame retardant consisted of 80 wt.% PPPO and 20 wt.% silicon resin possesses excellent flame retardancy for PC.LOI value of FR-PC is 33.0% and passes UL-94 V-0 rating.SEM revealed that the char yield as well as char properties have direct effects on the flame retardancy.
