| 目的 研究云爆剂中硝酸异丙酯渗漏对单基推进剂的安定性能影响。方法 利用加速量热仪(ARC)对单基推进剂在混合硝酸异丙酯环境下的热分解情况进行研究， 确定热分解特性参数， 并通过速率常数法计算出动力学参数。结果 得到了其绝热分解的温度、 压力时间曲线， 发现在混合硝酸异丙酯后， 样品起始热分解温度和表观活化能基本不变。结论 硝酸异丙酯对单基推进剂的起始分解温度和活化能没有明显影响， 不会危害其热安定性能。 |

| Objective To study the influence of Isopropyl Nitrate (IPN) leakage in fuel air explosive on the thermal stability of single-base propellant. Methods The thermal decomposition of single-base propellant under IPN was tested with accelerating rate calorimeter (ARC), and the thermal decomposition characteristic parameters were determined. The kinetic parameters were calculated by the rate constant method. Results Temperature-time curves and pressure-time curves were obtained for the thermal decomposition of single-base propellant. It was found that the initial exothermal temperature and apparent activation energy E remained almost the same after mixing with IPN. Conclusion These results showed that IPN did not significantly affect the initial exothermal temperature and activation energy of single-base propellant, and thus would not decrease its thermal stability. |
