摘要:
为了了解二硝基乙腈钾(DNCK)与火药常用组分之间的相容性,采用差示扫描量热法(DSC)研究了DNCK与这些组分之间的相互作用。结果表明:DNCK与DAGR吸收药、DA吸收药、硝化棉(NC)、硝基胍(NQ)、叠氮硝胺(DIANP)、1,3-二甲基-1,3-二苯基脲(C2)、2-硝基二苯胺(2-NDPA)相容性良好;与六硝基六氮杂异戊兹烷(CL-20)和N甲基-4-硝基苯胺(MNA)轻微敏感;与黑索今(RDX)、三羟甲基乙烷三硝酸酯(TMETN)和间苯二酚(Res)敏感;DNCK与奥克托今(HMX)和N-丁基硝氧乙基硝胺(BUNENA)混合体系的分解峰温较HMX和BUNENA单质组分分别提前了35.2 ℃和17.4 ℃,因此,与HMX和BUNENA不相容。
Abstract:
In order to study the compatibility between potassium dinitroacetonitrile(DNCK)and common propellant components, the DSC method was used to study the interaction of DNCK with these components. Results show that the systems of DNCK with DAGR absorbent powder, DA absorbent powder, nireocellulose(NC), nitroguanidine(NQ), 1,5-diazido-3-nitrazapentane(DIANP), 1,3-dimethyl1,3diphenylurea(C2) and 2-nitrodianiline(2-NDPA) are compatible, DNCK with hexanitrohexaazaiso-wurtzitane (CL-20) and Nmethyl-4-nitroanline(MNA) are slightly sensitive, and DNCK with cyclotrimethylene-trinitramine (RDX), trimethylolpropane trinitrate(TMETN) and resorcinol(Res) are sensitive. Decomposition peak temperature of the systems of DNCK with cyclotetramethylenete-tranitramine (HMX) and N-butyl-N-nitratoethylnitramine(BUNENA) are 35.2 ℃ and 17.4 ℃ earlier than that of HMX and BUNENA,respectively. Therefore, DNCK are incompatible with HMX and BUNENA.
