The compatibility of 3, 5-difluoro-2, 4, 6-trinitroanisole as a new melt-cast explosive carrier with a number of high explosives (RDX, HMX, CL-20 and TKX-50) and functional additives(powdered aluminum and ammonium perchlorate)was studied at the mass ratio of 1:1 by using DSC and VST methods. The detonation properties of DFTNAN/ RDX, DFTNAN/HMX, DFTNAN/CL-20, DFTNAN/Al and DFTNAN/AP mixtures were calculated. Experimental results of compatibility indicated that there were differences in the results of compatibility determination due to the differences in the test principles between DSC method and VST method. Through comprehensive analysis, DFTNAN showed good compatibility with RDX, HMX, CL-20, AP and Al except TKX-50. The results of detonation performance calculation exhibited that the addition of AP can effectively improve the oxygen balance of DFTNA. Among RDX, HMX and AP, the detonation energy of DFTNN/CL-20 mixed system was the biggest, with detonation velocity being 8899 m·s-1, detonation pressure 39.6 GPa, and detonation heat 6442 kJ·kg-1, which are 4.0 %, 32.9 % and 0.6 % bigger than those of pure DFTNAN, respectively., authors=WU Kai1 , JING Suming2 , HU Fei2 , authorsList=WU Kai, JING Suming, HU Fei, authorCompany=1.

3,5-二氟-2,4,6-三硝基苯甲醚(DFTNAN)是一种有望替代三硝基甲苯(TNT)的新型液相载体炸药。为了解 DFTNAN 与其负载材料的相容性,采用差示扫描量热法(DSC 法)和真空安定性试验方法(VST法),对DFTNAN与环三亚甲基三硝胺(RDX)、环四亚甲基四硝胺(HMX)、六硝基六氮杂异戊兹烷(CL-20)、1,1'–二羟基–5,5'–联四唑二羟胺盐(TKX-50)4种高能炸药和Al粉、高氯酸铵(AP)2种功能助剂在质量比为1∶1时的相容性进行了研究,并对 DFTNAN/RDX、DFTNAN/HMX、DFTNAN/CL-20、DFTNAN/Al 和 DFTNAN/AP 混合体系爆轰性能进行了理论计算。相容性研究结果表明:由于DSC法与VST法测试原理的差异,相容性判定结果存在较大差异,通过综合分析确定,除 TKX-50 外,DFTNAN 与 RDX 等均具有良好的相容性。爆轰性能计算结果表明:AP 的加入可有效改善 DFTNAN 炸药的氧平衡;相比于加入RDX、HMX和AP,DFTNAN/CL-20混合体系的爆轰能量最高,爆速达8899 m·s-1、爆压达39.6 GPa、爆热达6442 kJ·kg-1,较纯DFTNAN能量分别提高了4.0 %、32.9%和0.6%。

3,5-difluoro-2,4,6-trinitroanisole(DFTNAN)is a promising melt-cast carrier explosive that is expected to replace TNT. The compatibility of 3, 5-difluoro-2, 4, 6-trinitroanisole as a new melt-cast explosive carrier with a number of high explosives (RDX, HMX, CL-20 and TKX-50) and functional additives(powdered aluminum and ammonium perchlorate)was studied at the mass ratio of 1:1 by using DSC and VST methods. The detonation properties of DFTNAN/ RDX, DFTNAN/HMX, DFTNAN/CL-20, DFTNAN/Al and DFTNAN/AP mixtures were calculated. Experimental results of compatibility indicated that there were differences in the results of compatibility determination due to the differences in the test principles between DSC method and VST method. Through comprehensive analysis, DFTNAN showed good compatibility with RDX, HMX, CL-20, AP and Al except TKX-50. The results of detonation performance calculation exhibited that the addition of AP can effectively improve the oxygen balance of DFTNA. Among RDX, HMX and AP, the detonation energy of DFTNN/CL-20 mixed system was the biggest, with detonation velocity being 8899 m·s-1, detonation pressure 39.6 GPa, and detonation heat 6442 kJ·kg-1, which are 4.0 %, 32.9 % and 0.6 % bigger than those of pure DFTNAN, respectively.
