摘　　要：为了研究黑索金(RDX)含量对双基发射药膨胀系数的影响,制备了质量分数分别为10%、20%和30%的含RDX的双基片状发射药,采用TMA静态热机分析仪方法,对含RDX的双基发射药的膨胀系数及其玻璃化温度进行研究。结果表明:(1)随着单层双基药片中RDX含量的增加,其膨胀系数减小,有利于保持单层双基药片药型尺寸的精确性;(2)叠层双基药片的膨胀系数随着RDX含量的增加而减小,同时小于单层双基药片的膨胀系数;(3)单层双基药片玻璃化温度随RDX含量的增加而升高,其使用时适应的温度范围更广。In order to study the effect of different black gold content on the expansion coefficient of double-base propellant,high-energy propellant containing 10%,20%,30% black gold base was prepared,using TMA static heat engine analyzer method and origin analysis software.The expansion coefficient of the black gold-based dual-base propellant and its glass transition temperature were investigated.The results showed that:(1)With the increase of black gold content in single-layer double-base tablets,the expansion coefficient was reduced,which was beneficial to maintain the accuracy of the size of single-layer double-base tablets.(2)The expansion coefficient of the laminated double-base tablet decreased as the black gold content increased,and smaller than the expansion coefficient of the single-layer double-base tablet.(3)The glass transition temperature of the single-layer double-base tablet increased with the increase of the black gold content,and it can be used in a wider temperature range.
