Study on Thermal Decomposition Kinetic of PA6 Flame-Retarded by Brominated Polystyrene Synchronized with Antimony Trioxide

摘要：

The thermal stability and thermal degradation kinetics of pure polyamide (PA6) and PA6 flame-retarded by brominated polystyrene (BPS) synchronized with antimony trioxide (Sb2O3) (FR/PA6) were investigated by TG analysis at different heating rates. The thermal decomposition activation energy of PA6 and FR/PA6 were determined by using Kissinger and Flynn-Wall-Ozawa methods. The thermal decomposition kinetic mechanism, the reaction model and the non-isothermal kinetic equation of PA6 and FR/PA6 were determined by Coats-Redfern method. The results show that the addition of BPS synchronized with Sb2O3 can advance the flame-retarded performance of PA6 and change the decomposition pattern of PA6. The thermal decomposition mechanism function of PA6 is g(a)= 2(1-a)-1/2-1, and the reaction order is n=1.5. The thermal decomposition mechanism function of FR/PA6 is g(a)= -ln( 1 -a), and the reaction order is n= 1.
