Abstract
A new type of phosphorus-based flame retardant (ADCP) was added to polyamide (PA). Product thermostability was analysed using the thermogravimetric analyser. Flame retardant properties were investigated by adding ADCP to PA. The limiting oxygen index and vertical burning were also determined. In addition, the results of thermal decomposition kinetics of PA materials with and without the flame retardant were analysed by the Kissinger method and the Flynn Wall Ozawa method, respectively. Subsequently, the required thermal decomposition activation energy was calculated and the accuracy and reliability were checked. Coast Redfern theory model was used to verify the thermal decomposition mechanism function model, and the kinetic equation and reaction mechanism were obtained. The thermal decomposition mechanism of the material was evaluated, which proved the efficiency of ADCP flame retardant.
