Features of Thermolysis of High-Energy Materials with Tetrazole Binders

Abstract— The paper presents the results of experimental studies of the thermal characteristics of high-energy compounds based on low-sensitivity oxidants, 5-nitro-1,2-dihydro-3H-1,2,4-triazin-3-one, 1,3,5-triamino-2,4,6-trinitrobenzene, and 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo[5.5.0.0^5,9.0^3,11]dodecane, and tetrazole binders based on allylated poly-N-methyl-5-vinyltetrazole (PMVT-A). Differential scanning calorimetry and thermogravimetric analysis were used to study the thermal properties of the compositions, the features of thermolysis, and the chemical compatibility of the components. It was shown that binders based on PMVT-A plasticized with propylene glycol dinitrate or nitroamine/nitroester mixtures are fully compatible with the crystalline oxidant, 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetrcyclone[5.5.0.0^5,9.0^3,11]dodecane, and completely incompatible with 5-nitro-1,2-dihydro-3H-1,2,4-triazine-3-one.
