The interaction of 3,6-dihydrazino-1,2,4,5-tetrazine(DHT) with main components of solid propellant was studied by DSC,and the interaction of DHT with the slurry of CMDB propellant was investigated by curing experiment.The results show that there are no obvious interaction between DHT with cyclotetramethylenete-tranitra-mine (HMX),hexanitrohexaazaisowurtzitane (CL-20),nitrocellulose (NC),aluminum powder (Al powder),carbon black (CB),polyethylene glycol(PEG),2-nitrodianiline (2-NDPA),1,3-dimethyl-1,3-diphenyl urea (C2) and diisocyanate (N100).The influence between them is a main physical process.There are the strong interaction between DHT with nitroglycerine (NG),cyclotrimethylene-trinitramine (RDX),3,4-dinitrofurazanofuroxan (DNTF),N-guanylurea-dinitramide (FOX-12),N-nitrodihydroxyethylaminedinitrate (DINA) and resorcinol (Res).DHT is found to partly dissolve in these components or to form an eutectic system with these components that can decrease the decomposition temperature of DHT.The DHT/CMDB propellant mixture system can fire when the slurry of the propellant is cured at 70℃ for about 40 minutes,indicating that DHT can not be applied to the double-base propellant or other energetic mixture system that NG is as the main component.%采用差示扫描量热法(DSC)研究了3,6-二肼基-1,2,4,5-四嗪(DHT)与推进剂常用单组分之间的相互作用.采用推进剂固化实验,考察了DHT与CMDB推进剂药浆的相互作用.结果表明,在实验温度范围内,DHT与奥克托今(HMX)、六硝基六氮杂异戊兹烷(CL-20)、硝化棉(NC)、铝粉(Al)、炭黑(CB)、聚乙二醇(PEG)、2-硝基二苯胺(2-NDPA)、1,3-二甲基-1,3二苯基脲(C2)和二异氰酸酯(N-100)之间没有明显的相互作用,它们之间的影响主要是物理作用过程;DHT与硝化甘油(NG)、黑索今(RDX)、3,4-二硝基呋咱基氧化呋咱(DNTF)、N-脒基脲二硝酰胺(FOX-12)、吉纳(DINA)和间苯二酚(Res)之间存在强烈的相互作用;DHT可部分溶于这些组分或其熔融液相或与这些组分形成低共熔体系,使DHT的分解明显提前.在70℃固化条件下,混合药浆40min左右发生着火,表明DHT与CMDB推进剂多组分混合体系之间具有强烈的化学作用,不能应用于双基体系的推进剂或以NG为主要组分的其他含能混合体系.
