摘　　要：为研究保温材料发泡聚苯乙烯(EPS)热稳定性与热危险性,运用TG-DSC-MS-IR联用仪对EPS分别在10℃/min、20℃/min、30℃/min、50℃/min四种不同升温速率下进行测试,并利用Kissinger法、Ozawa法对实验所得到的数据进行热力学分析,计算得到了活化能和指前因子等动力学参数,依据DSC实验数据得出:不同实验条件下活化能相差不大,随着升温速率的升高,分解需要的能量减少,火灾的潜在危险性升高。In order to investigate the thermal stability and thermal safety of EPS,using of TG-DSC-MS-IR instrument tested 10℃/min、20℃/min、30℃/min、50℃/min four different heating rates of EPS,And using the Kissinger method,Ozawa method for thermodynamic analysis of the experimental data obtained,the calculated kinetic parameters of activation energy and preexponential factor,analysis of DSC data obtained activation energy little difference,With increasing heating rate,decomposition of the energy needed to reduce the potential increased risk of fire.
