3,4-二硝基吡唑的热行为及其与某些炸药组分的相容性

摘要

用差示扫描量热(DSC)和热重/微分热重(TG/DTG),研究了3,4-二硝基吡唑(DNP)的热行为.用DSC法和真空安定性(VST)考察了DNP与炸药组分材料,包括2,4-二硝基苯甲醚(DNAN)、1,3,3-三硝基氮杂环丁烷(TNAZ)、黑索今(RDX)、奥克托今(HMX)、六硝基六氮杂异伍兹烷(CL-20)、高氯酸铵(AP)、Al、微晶蜡的相容性.结果表明:DNP的热分解过程分两个阶段,第一阶段DSC曲线的分解峰温出现在319.8℃,显示DNP有好的热稳定性,第二阶段DSC曲线峰温为407.2℃.DNP与DNAN、TNAZ、RDX、HMX、CL-20、AP、A1、微晶蜡均相容.这些物质可用作炸药组分.%Thermal behaviors of 3,4-dinitrophyrazole (DNP) were investigated by differential scanning calorimetry (DSC) and thermal gravity/differential thermal gravity(.TG-DTG).The compatibilities of DNP with some explosive component materials,including 2,4-dinitroanisole(DNAN),1,3,3-trinitroazetidine (TNAZ),cyclotrimethylene trinitramine (RDX),cyclotetramethylene tetranitramine(HMX),hexanitrohexaazaisowurtzitane(CL-20),ammonium perchlorate(AP),Al and m icrocrystal wax were discussed by vacuum stability test (VST) and DSC.Results show that thermal decomposition process of DNP can be divided into two stages.The peak temperature of DSC curve for the first stage is 319.8 ℃,which revealing that DNP has superior thermal stability.And the peak temperature of DSC curve for the second stage is 407.2 ℃.The compatibilities of DNP with DNAN,TNAZ,RDX,HMX,Cl-20,AP,Al and microcrystal wax are good.These materials can be used as components in explosives.
