摘要:
为了深入认识石蜡（PW）对奥克托今（HMX）热分解特性的影响，采用C80型微量热仪研究了PW与24、 75、 103、 250 μm不同粒径的HMX（质量比为1∶1）混合物的热分解过程。通过动力学模型适配法得到了PW/HMX混合物的反应模型，分析了HMX粒径及PW含量对PW/HMX混合物热分解特性的影响。结果表明：PW主要影响HMX的初始分解阶段；HMX粒径的降低，有利于PW与HMX表面的相互作用，并使初始分解反应温度降低，放热峰温提前。针对24 μm的HMX，设计了5%、 10%、 30%、 50%不同质量分数的PW调制样品,开展绝热加速量热实验。绝热条件下，PW/HMX混合物的分解表现为一步分解反应。随着PW含量的降低，绝热分解中n级反应的主导作用降低，自催化作用增强。基于动力学进一步考察了PW对HMX自加速分解温度的影响。结果表明，PW的引入会导致自加速分解温度降低，降低的幅度随HMX粒径的降低和PW含量的增加而增大。
