Thermal Degradation of Flame Retardant Cotton Cellulose

Abstract

Cellulose treated with flame retardant was studied by thermogravimetry (TG), differential thermal analysis (DTA), limiting oxygen index (LOI) and IR. The kinetic parameters for the thermal degradation are obtained following the method of Broido. For the flame retardant cellulose, the activation energy and decomposition temperature were much decreased while char yield and LOI were increased. The main thermal decomposition of the samples with higher LOI occurs at lower temperatures, while that with lower LOI occurs at higher temperatures.
