摘要： 为研究2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPyO)与丁腈橡胶(NBR)造型粉的热安全性,通过水悬浮溶解蒸馏法将ANPyO制成ANPyO/NBR造型粉,运用热重和差示扫描量热法(TG-DSC)分析仪研究ANPyO/NBR的热分解反应行为,采用Kissinger法、Ozawa法和多种积分法计算热分解动力学参数,得到ANPyO/NBR自加速分解温度、热点火温度、热爆炸临界温度,并计算获得半径为1m的球形ANPyO/NBR样品在不同超临界环境温度下的延滞期。结果表明:造型粉ANPyO/NBR有良好的耐热性能,热安全性较高;环境温度对ANPyO/NBR造型粉热安全性起着决定性作用。

Abstract: In order to study the thermal safety of ANPyO and NBR moulding powder, the ANPyO was improved moldability with NBR by means of the solution-water suspending-distillation method and its thermal behavior was studied by Thermogravimetric-Differential Scanning Calorimeter(TG-DSC)thermal analyzer. The thermal decomposition activation energy and the pre-exponential factor were calculated by Kissinger method, Ozawa method and various integral methods. And the self-accelerating decomposition temperature, the thermal ignition temperature, and the critical temperature of thermal explosion of ANPyO/NBR were calculated. Then the time to ignition of spherical ANPyO/NBR samples with radius of 1m at different supercritical ambient temperatures was calculated. The results show that the moulding powder ANPyO/NBR has good heat resistance and thermal safety performance, and that the thermal safety of ANPyO/NBR is decided by the ambient temperature.

Key words: 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO), nitrile butadiene rubber (NBR), thermal safety, ambient temperature, time to ignition
