摘要
为研究新型嗪类、唑类N杂环富氮含能材料在发射药中的应用前景,采用差示扫描量热法(DSC)和真空安定性试验(VST)分析了4,4′,6,6′-四(叠氮基)肼-1,3,5-三嗪(TAHT)、偶氮四唑二氨基胍盐(GZT)与发射药常规组分硝化棉(NC)、1,5-二叠氮基-3-硝基氮杂戊烷(DIANP)、丙三醇三硝酸酯(NG)、黑索今(RDX)、硝基胍(NQ)等的化学相容性。试验结果表明:TAHT与叠氮硝胺药片(DA)、双基药片(SN)、NQ或RDX的混合物中,TAHT的热分解峰温变化△T_(p)分别为-0.4、-0.1、-6.7、-1.4℃,相容性等级均为A,混合物真空安定性净增放气量R分别为0.09、 0.42、 0.47、 0.31 mL/g,相容性良好;GZT与DA、SN、RDX或NQ的混合物中,GZT的热分解峰温变化△Tp分别为8.8、-4.9、 30.8、 47.7℃,相容性等级分别为B、A、D、D,混合物真空安定性净增放气量R分别为0.09、 0.32、 1.30、 1.50 mL/g,与DA、SN相容,与RDX、NQ不相容。
In order to study the application prospect of novel azines and azoles nitrogen heterocyclic nitrogen-rich energetic materials in propellants,the chemical compatibility of 4,4′,6,6′-tetraazide hydrazine-1,3,5-triazine(TAHT),azotetrazoldiaminoguanidine(GZT)and the conventional components of propellants,such as nitrocellulose(NC),1,5-diazido-3-nitroazapentane(DIANP),glycerol trinitrate(NG),1,3,5-trinitro-1,3,5-triazane(RDX),nitroguanidine(NQ),was studied by differential scanning calorimetry(DSC)method and vacuum stability test(VST)method.The experimental results show that the thermal decomposition peak temperature changes△T_(p) of TAHT in the mixture of TAHT and DA,SN,NQ or RDX are-0.4,-0.1,-6.7℃and-1.4℃,respectively,and the compatibility grade is Grade A.R of the vacuum stability of the mixtures are 0.09,0.42,0.47 mL/g and 0.31 mL/g,respectively,indicating good compatibility.The thermal decomposition peak temperature changes△T p of GZT in the mixture of GZT and DA,SN,RDX or NQ are 8.8,-4.9,30.8℃and 47.7℃,respectively,and the compatibility levels are B,A,D and D,respectively.R of the vacuum stability of the mixtures are 0.09,0.32,1.30 mL/g and 1.50 mL/g,respectively.It is compatible with DA and SN,but incompatible with RDX and NQ.
