DNAN降低DNTF冲击波感度研究

通过冲击波感度、红外光谱、X射线衍射和扫描电镜等试验,研究了3,4-二硝基氧化呋咱(DNTF)、二硝基茴香醚(DNAN)以及不同比例DNTF/DNAN共熔物冲击波感度的变化情况,从其红外谱图、晶面间距和晶体形貌的变化规律分析了DNAN降低DNTF冲击波感度的机理。研究结果表明,加入DNAN能够有效降低DNTF的冲击波感度,DNAN质量为20%左右综合性能较好,降低冲击波感度的同时,不产生晶体缺陷。

Shock Sensitivity of DNTF Reduced by Using DNAN

Shock sensitivities of 3,4-dinitrofurazanfuroxan(DNTF),2,4-dinitroanisole(DNAN),different proportion of DNTF and DNAN co-melt explosive were studied by shock sensitivity test, IR spectrum,X-ray diffraction and scan electron microscope methods. From the changing law of IR spectra, interplanar spacing, crystal form, the mechanism of shock sensitivity of DNTF reduced by DNAN was discussed. Results show that DNAN can decrease the shock sensitivity of DNTF. The DNTF/DNAN 80/20 co-melt explosive has good integrated performance between sensitivity to shock and crystal structure.
