Abstract

The interaction of 3,6-dihydrazino-1,2,4,5-tetrazine(DHT)with main components of solid propellant was studied by DSC, and theinteraction of DHT with the slurry of CMDB propellant was investigated bycuring experiment. The results show that there are no obvious interactionbetween DHT with cyclotetramethylenete-tranitramine (HMX),hexanitrohexaazaisowurtzitane (CL-20), nitrocellulose (NC), aluminum powder (Alpowder), carbon black (CB), polyethylene glycol(PEG), 2-nitrodianiline (2-NDPA),1,3-dimethyl-1,3-diphenyl urea (C2) and diisocyanate (N100). The influencebetween them is a main physical process. There are the strong interaction betweenDHT with nitroglycerine(NG),cyclotrimethylene-trinitramine (RDX), 3,4-dinitrofurazanofuroxan(DNTF),N-guanylurea-dinitramide(FOX-12),N-nitrodihydroxyethylaminedinitrate (DINA) and resorcinol (Res). DHT is foundto partly dissolve in these components or to form an eutectic system with thesecomponents that can decrease the decomposition temperature of DHT. The DHT/CMDBpropellant mixture system can fire when the slurry of the propellant is curedat 70℃ for about 40 minutes, indicating that DHT can not be applied to thedouble-base propellant or other energetic mixture system that NG is as the maincomponent.
