摘要：

The thermal decomposition kinetics and flame retardant property of epoxy resin cured with phosphazene and non-phosphorus curing agent in N2 and air atmosphere respectively were studied by TG-DTG. Six thermal decomposition kinetics model were affirmed and their activation energy, pre-exponential factor were also calculated through the Achar and Coats-Redfern methods. The results show that even though decomposed easily in the initial heating phase, the phosphazene-containing epoxy resin has an obvious flame retardant effect during high-temperature phase and a higher char yield in later thermal cracking compared with the non-phosphorus containing epoxy resin. In some extent, the activation energy has a great relationship with the flame retardant mechanism. © 2016, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
