摘要
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.
