为获得有机硅阻燃环氧树脂体系在热降解过程中的动力学数据，并阐明有机硅阻燃剂的作用机理，使用Change法对该体系的热降解动力学进行分析，结果发现该体系的热降解过程为一级反应。相比于空白体系，阻燃体系的平均热降解活化能更高，成炭性能更好，这表明有机硅阻燃剂在材料热降解过程中起到了较好的稳定作用，最终达到了提高阻燃体系成炭率和阻燃性的目的。

In order to obtain the kinetic data of epoxy resin/silicon flame-retardant system in the process of thermal decomposition,and understand the flame-retardant mechanism of the silicone. The thermal decomposition kinetics of the flame-retardant system was focused. The results show that the thermal decomposition process is a first order reaction. Compared to the pure epoxy resin,the average activity energy and the char yeild of the flame-retardant system are both higher. It indicates that the silicone flame retardant enhances the thermal stability of epoxy resin,finally improves the char yeild and flame retardancy of the system.
