非阻燃型和阻燃型XPS在空气中的热解特性研究

摘要

The thermal degradation properties of two extruded polystyrene temperature holding materials were investigated using TG-DSC-MS-IR simultaneous analysis method. The research showed that the additive in the fire retardant XPS can extend the time in reaching the maximum heat release rate, reduce the variety and amounts of the products, and improve the activation energy of the reaction. Though residual fire retardant materials reacted and gave off heat after 491 ℃.%运用热重-差热-红外-质谱(TG-DSC-IR-MS)联用技术对非阻燃型和阻燃型挤出聚苯乙烯泡沫塑料(XPS)保温材料在空气中的热解特性进行研究.结果表明,阻燃添加剂延长了阻燃型XPS到达最大热释放速率所需要的时间,减少了热解产物的种类和数量,以及提高了反应的活化能；而且,材料中残留的阻燃剂在491℃以后会继续热解并放出热量.
