“…Currently, a number of melt-cast explosive carriers which are expected to replace TNT have been synthesized, such as 2,4-dinitrobenzene (DNAN), 3,4-dinitropyrazole (DNP) [ 13 ], 1-methyl-3,4,5-trinitropyrazole (MTNP) [ 14 ], 1-methyl-2,4,5-trinitroimidazole (MTNI) [ 15 , 16 ], 3,4-dinitrofurazanfuroxan (DNTF) [ 17 ], 1-methyl-3,5-dinitropyrazole (DNMT) [ 18 ], 1-nitroamino-2,3-dinitrate propane (NG-N1) [ 19 ], etc. However, these suffer from different shortcomings and do not meet the requirements of widespread application.…”

In this paper, the thermal decomposition behavior of 3,5-difluoro-2,4,6-trinitroanisole (DFTNAN) was studied by differential scanning calorimetry (DSC) and thermogravimetry (TG) by using different heating rates (2, 5, 10, 15 °C·min−1). Subsequently, the kinetic and thermodynamic parameters of non-isothermal thermal decomposition of DFTNAN were calculated. The critical temperature of thermal explosion (Tb) and self-accelerating decomposition temperature (TASDT) were determined to be 249.03 °C and 226.33 °C, respectively. The compatibility of DFTNAN with a number of high explosives (cyclo-1,3,5-trimethylene-2,4,6-trinitramine (RDX), 1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaaza-tetracyclo-[5.5.0.05,9.03,11]-dodecane (CL-20) and dihydroxylammonium 5,5’-bistetrazole-1,1’-diolate (TKX-50)) was studied at different mass ratios using DSC. The criteria to judge the compatibility between the materials were based on a standardization agreement (STANAG 4147). The thermodynamic study results revealed that DFTNAN possessed superior thermal safety and stability. The experimental of compatibility results indicated that the mass ratios of the high explosives in the DFTNAN/RDX, DFTNAN/HMX and DFTNAN/CL-20 compositions more than 40%, 60% and 70% exhibited good compatibility, whereas DFTNAN/TKX-50 demonstrated poor compatibility.

“…The compatibility rating of the mixed system of propellant and microcapsules were evaluated by the change value of peak temperature (Δ T p) and the apparent activation energy change rate Δ E / E a [32, 33]. The Criteria for good compatibility (rating A) is Δ T p≤2.0°C and Δ E a/ E a≤20 %.…”

Metatitanic acid/urea‐formaldehyde microcapsules were synthesized to inhibit the erosion of gun barrel resulting from the propellant combustion. The microcapsules were prepared by one‐step in‐situ polymerization method. SEM and EDS were employed to characterize the morphology, core‐shell structure and the chemical composition of the microcapsules. FTIR spectra and XRD patterns confirmed the formation of crystalline urea‐formaldehyde resin on the surface of the metatitanic acid particle. TG results showed that the thermal decomposition residue weight ratio of the microcapsules in air was 12.8 %. Kinetic parameters of thermal decomposition of propellant with and without the microcapsules were calculated based on the DSC results, respectively, which proved the good compatibility between the microcapsules and the double‐base propellant. Erosion tube comparative test showed the wear‐reducing efficiency reached 18.54 % with 1.5 wt.% addition of microcapsules. The combination of metatitanic acid and urea‐formaldehyde resin surprisingly resulted in a synergistic effect, which was attributed to the better dispersibility of TiO2 particles generated by metatitanic acid microcapsules. The metatitanic acid/urea‐formaldehyde microcapsules exhibit a potential application for propellant erosion additive.

“…where: TPS and TPM are the exothermic peak temperatures of the single system and the mixture of explosive with the polymer, respectively. The single system is the component in which its exothermic peak temperature is lower than that of another component in the mixture system [17,18,19]. According to the standard [12], if ΔTP ≤ 4 °normalC, the mixture is determined as compatible; if ΔTP ≥ 20 °normalC, the mixture is incompatible; if ΔTP is between 4 and 20 °C, another method is recommended to determine the compatibility.…”

The chemical compatibility and the adhesion of energetic materials and additive materials exert a strong influence on the sensitivity, safety and performance of a polymer-bonded explosive (PBX). In this study, the chemical compatibility of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), pentaerythritol tetranitrate (PETN) with several polymers were evaluated using the vacuum stability test (VST) and the differential scanning calorimetry (DSC); while the adhesion between RDX or PETN and each binder based on these polymers was determined through interfacial characteristics using contact angle measurement. The experimental results demonstrate that RDX and PETN are compatible with polystyrene (PS), nitrocellulose (NC) and fluoroelastomer (FKM) according to the STANAG 4147. Therefore the two polymers can be used as adhesives in PBX composition. Moreover, based on interfacial characteristics such as interfacial tension and work of adhesion, the adhesion between RDX and each binder was predicted to be better than that of PETN.
