| 摘 要： | 采用热重分析方法研究纯聚乙烯、阻燃聚乙烯在空气气氛中的热降解行为,并采用Kissinger法和Flynn-Wall-Ozawa(FWO)法计算其热降解动力学参数。计算结果表明,阻燃聚乙烯的活化能高于纯聚乙烯,阻燃剂的加入提高了聚乙烯的热稳定性。

| Abstract: | The thermal degradation kinetics parameter of pure polyethylene and flame-retardant polyethylene were determined by Kissinger and Flynn-Wall-Ozawa(FWO) method using the thermal gravimetric analysis technique under air atmosphere.The calculation results showed that the activation energy of the flame-retardant polyethylene was higher than the pure polyethylene,the thermal stability of polyethylene was improved the flame retardants added. |
