Abstract:

用DSC和TG-DTG研究了十氢十硼酸双四乙基铵([(C2H5)4N]2B10H10,BHN)的热行为,并分别用DSC法和真空安定性法考察了BHN与推进剂主要组分六硝基六氮杂异伍兹烷(CL-20)、3,4-二硝基呋咱基氧化呋咱(DNTF)、N-脒基脲二硝酰胺盐(FOX-12)、奥克托今(HMX)、端羟基叠氮聚醚(GAP)、黑索今(RDX)、高氯酸铵(AP)、3-硝基-1,2,4-三唑-5-酮铅(NTO-Pb)、端羟基聚丁二烯(HTPB)、癸二酸二异辛酯(DOS)、2,4-甲苯二异氰酸酯(TDI)、异佛尔酮二异氰酸酯(IPDI)、己二酸酮(AD-Cu)、Al粉和Mg粉的相容性。结果表明,BHN的热分解存在一个主放热峰,10℃·min-1时的分解峰温为305.8℃,其与CL-20、HMX、GAP、RDX、AP、NTO-Pb、HTPB、DOS、IPDI、AD-Cu、Al粉和Mg粉等均相容,可与上述材料混合应用于火炸药的制备,但与TDI混合有中等反应现象。
