摘　　要：为了研究表面包覆有氟橡胶F_(2311)的ANPyO造型粉(ANPyO/F_(2311))的热安全性,使用DSC-TG法研究了ANPyO/F_(2311)的热分解反应过程,通过Kissinger法、Ozawa法等多种计算方法分析其热分解机理,计算得出热分解活化能、指前因子、动力学机理函数微分式、自加速分解温度、热点火温度以及热爆炸临界温度等相关参数。进而计算出在323.15 K环境温度下,特征尺寸1 m的ANPyO/F_(2311)在不同形状(球、无限圆柱、无限平板)时的临界热爆炸温度T_(acr)、热感度概率密度函数S(T)、安全度D_(S)和热爆炸概率P_(TE)。从结果可得出,ANPyO/F_(2311)具有良好的耐热性能,球形样品的热安全性相对较高,无限平板样品的热安全性相对最低。In order to study the thermal safety of ANPyO coated with fluorine rubber F_(2311)(ANPyO/F_(2311)),the thermal decomposition reaction process of ANPyO/F_(2311) was studied by DSC-TG method.The thermal decomposition mechanism was analyzed by Kissinger method,Ozawa method and other calculation methods.The thermal decomposition activation energy,pre exponential factor,differential equation of kinetic mechanism function,self-accelerating decomposition temperature,thermal ignition temperature,and thermal explosion critical temperature were obtained.Then the critical thermal explosion temperature T_(acr),thermal sensitivity probability density function S(T),safety degree D_(S) and thermal explosion probability P_(TE) of ANPyO/F_(2311) samples with critical dimension of 1 m under different shapes(sphere,infinite cylinder,infinite plate)were calculated at 323.15 K.The results show that ANPyO/F_(2311) has good heat resistance,the thermal safety of spherical sample is relatively high,and that of infinite plate sample is relatively low.
