摘　　要：目的 预估2/1樟发射药的安全贮存寿命,建立一种基于加速热减量试验,利用热减量曲线和贝瑟洛特(Berthelot)方程预估其安全贮存寿命的方法。方法 首先对2/1樟发射药分别进行85、95、105、115℃下的加速热减量试验,获得样品在各个温度下不同加速时间的热减量数据。然后基于热减量曲线,得到2/1樟发射药在各个温度下的延滞期。最后利用各个温度下的半延滞期,根据Berthelot方程拟合得到2/1樟发射药安全贮存寿命预估模型。结果 根据其安全贮存寿命预估模型计算得到2/1樟发射药在30℃下的安全贮存寿命约为50.9 a。结论 预测结果与文献值接近,且试验时间比文献减少了近1/2,验证了该方法的有效性,可为2/1樟发射药或其他发射药的安全贮存寿命预估提供一种可行的技术途径。The work aims to establish a method based on accelerated heat reduction test to predict the safe storage life of 2/1 camphor propellant by heat reduction curve and Berthelot equation.Firstly,the accelerated heat reduction tests of 2/1 camphor propellant were carried out at 85℃,95℃,105℃and 115℃respectively,and the heat reduction data of the samples at dif-ferent temperature for different acceleration time were obtained.Then,based on the heat reduction curve,the delay period of 2/1 camphor propellant at each temperature was obtained.Finally,the safe storage life prediction model of 2/1 camphor propellant was obtained by fitting the half-lag period at each temperature according to the Bethelot equation.According to its safe storage life prediction model,the safe storage life of 2/1 camphor propellant at 30℃was about 50.9 years.The prediction results are close to the literature values,which verifies the effectiveness of the method proposed and the test time is reduced by nearly half compared with that in the literature.The method can provide a feasible technical way for the safe storage life prediction of 2/1 camphor propellant or other propellants.
