| description | The results are presented of the study of thermal decomposition kinetics of the K – 2 model mixed energetic material, the main components of which are ammonium perchlorate, octogen, aluminum and an inert binder, polybutadiene, plasticized with transformer oil. The activation energy E was determined by isoconversion methods and the Kissinger method according to thermal analysis at heating rates b < 5 K / min. In an open system, the evaporation of plasticizer (Emin = 65 kJ / mol), thermal decomposition of octogen (Emax = 192 kJ/mol) and ammonium perchlorate are successively realized in the samples. When limiting the free exit of gaseous reaction products, the peaks of the maximum heat release rate in octogen shift to the region of higher temperatures, the thermal decomposition of K – 2 is completed earlier than in the open system. An explanation of the mechanism of this phenomenon is proposed. |
