摘要 采用差示扫描量热法(DSC)和表观活化能变化率,研究了高能硼氢燃烧剂(十氢十硼酸双四乙基铵,BHN)与缩水甘油叠氮聚醚(GAP)、黑索今(RDX)、奥克托金(HMX)、3-硝基-1,2,4-3-己基铅(NTO-Pb)、六硝基六氮杂异伍兹烷(CL-20)、铝粉(Al,12.18μm)、镁粉(Mg,200~325目)、3,4-二硝基呋咱基氧化呋咱(DNTF)和N-脒基脲二硝酰胺盐(GUDN)等含能组分的相容性;同时,还研究了BHN与聚对苯二甲酸乙二醇酯(PET,M=6 000)、聚乙二醇(PEG,M=10 000)、二异氰酸酯(N-100)、端羟基聚丁二烯(HTPB)、己二酸铜(AD-Cu)、2,4-二羟基苯甲酸铜(β-Cu)、邻苯二甲酸铅(φ-Pb)、炭黑(CB)、三氧化二铝(A12O3)、l,3-二甲基-1,3-二苯基脲(C2)、癸二酸二异辛酯(DOS)和高氯酸钾(KP)等惰性材料的相容性。研究结果表明,BHN与NTO-Pb、CL-20、A1、Mg、PET、PEG、N-100、HTPB、CB、Al2O3、C2、DOS和KP相容性较好,与GAP和HMX轻微敏感;AD-Cu、β-Cu和φ-Pb敏感,而与RDX、DNTF和GUDN不相容。由此可见,BHN与固体推进剂的主要组分相容性良好,可在HTPB/AP/Al体系的复合固体推进剂中应用。 The compatibility of high energetic boron-hydrogen incendiary agent (tetraethylammonium dodecahydrododecabo- rates,BHN) with some energetic components and inert materials in solid propellants was studied by means of DSC method and ac- tive energy transformation, among which glycidylazidopolymer ( GAP), cyclotrimethylenetrinitramine ( RDX), cyelotetramethylenetet- ranitroamine ( HMX), lead 3-nitro-1, 2,4-triazol-5-onate ( NTO-Pb ), hexanitrohexaazaisowurtzitane ( CL-20 ), aluminum powder (A1, particle size is 12.18 μm), magnesium powder (Mg, particle size is 44 ~ 47 μm), 3,4-dinitrofurzanfuroxan (DNTF) and N- guanylurea-dinitramide (GUDN) were used as energetic components and polyoxytetramethylene-eo-oxyethylene (PET), polyethy- lene glycol (PEG) ,addition product of hexamethylene diisocyanate and water (N-100), hydroxyl terminated polybutediene (HT- PB) ,cupric adipate (AD-Cu), cupric 2,4-dihydroxy-benzoate (β-Cu) ,lead phthalate ( φ-Pb), carbon black (CB), aluminum ox- ide ( AI2 03 ), 1,3-dimethyl-1,3-diphenyl urea ( C2 ), di-2-ethylhexyl sebaeate ( DOS ) and potassium perehlorate (KP) were used as inert materials. The results show that the binary systems of BHN with NTO-Pb, CL-20, Al, Mg, PET, PEG, N-100, HTPB, CB, Al2O3, C2, DOS and KP are compatible, BHN with GAP and HMX are slightly sensitive, BHN with AD-Cu,β-Cu and φ-Pb are sen- sitive, BHN with RDX, DNTF and GUDN are incompatible.
