Kinetic predictions for CL-20 and its PBXs using models obtained by master plots and combined kinetic methods
Original language description
The decompn. reaction models and thermal hazard properties of different 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) polymorphs and their PBXs bonded by Semtex 10, C4, Viton A and Fluorel matrixes have been investigated based on master plots and combined kinetic methods. The use of "isoconversional and combined kinetic anal." method yield reliable kinetic triplets, which could be employed to predict the thermal behavior of energetic materials at 82 °C. The effect of the Fluoropolymers on the decompn. mechanism of CL-20 is significant and similar. It has also been shown that the polymer matrixes contg. mineral oil materials and plasticizers (Semtex and C4) have little effect on decompn. mechanism of CL-20. According to isothermal simulations, the threshold cook-off time until loss of functionality at 82 °C for all involved materials are much more than 500 days, and under the effect of polymer matrixes, the storage time of CL-20 has been greatly extended.
