摘要:
为了获取DNAN/DNTF二元共熔物安全性的变化规律，利用机械感度仪和DSC测试得到了DNAN、DNTF及二元共熔物的机械感度和热分解曲线，并采用Materials Studio软件对二元共熔物进行了分子动力学模拟。结果表明，二元共熔物的机械感度和热感度均随DNTF含量的提高而变差。DNTF引发键N—O的最大键长均随DNTF含量的增加而变大，共熔物的结构稳定性变差，与共熔物机械和热刺激下的安全性变化趋势一致。DNTF引发键N—O的最大键长可以作为DNAN/DNTF二元共熔物机械感度和热安全性相对大小的理论判据。
Abstract:
In order to obtain the change rule of safety of DNAN/DNTF binary eutectic, the mechanical sensitivity and thermal decomposition curves of DNAN, DNTF and DNAN/DNTF binary eutectic were obtained by using mechanical sensitivity apparatus and DSC, and the molecular dynamics simulation of the binary eutectic was performed by Materials Studio Software. Results show that mechanical sensitivity and thermal sensitivity of the binary eutectic decrease with the increase of DNTF content. With the increase of DNTF content, maximum bond lengths of N—O initiated by DNTF increase, and the structural stability of the eutectic becomes worse, which was consistent with the changing trend of safety of the eutectic under mechanical stimulation and thermal stimulation. Maximum bond length of DNTF initiating bond (N—O) can be used as a theoretical criterion for the relative degree of mechanical sensitivity and thermal safety of DNAN/DNTF binary eutectic.
