Thermal behavior and decomposition kinetics of Viton A bonded explosives containing attractive cyclic nitramines

Popis výsledku v původním jazyce

The thermal behavior and decompn. kinetics of Viton A bonded PBXs contg. some attractive cyclic nitramines were investigated by means of nonisothermal TG and DSC techniques. It has been shown that only a single decompn. process has been obsd. for RDX-VA,CL-20-VA and HMX-VA while an obvious two-step process for BCHMX-VA under 1.0° min-1. The exothermic onset temps. of RDX-VA, BCHMX-VA, HMX-VA and CL-20-VA were found as 212.6, 241.3, 277.6, and 237.8° with the peak max. of 234.1, 242.6, 278.7, and 238.6°, resp. Their corresponding heat releases were detd. as 1552, 1263, 1302, and 1597 J g-1, which are much lower than that of the pure cyclic nitramines. It has been proved that Formex polymer is not good binder for BCHMX, while Viton A is better than C4 and Formex as the binder of cyclic nitramines for the sake of greater thermal stability. Viton A has a significant effect on the activation energy distribution of cyclic nitramines, and the initial autocatalysis effect for RDX and BCHMX wa
