%X The curing and rheological properties of the slurry of an hydroxyl-terminated polybutadiene (HTPB)/2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20)-blended explosive were studied using differential scanning calorimetry and viscosity measurements. The curing kinetic parameters of the slurry were calculated using the Kissinger method and the Ozawa method to obtain a dual-Arrhenius model under thermostatic conditions. The activation energy for the curing reaction of the slurry was found to be 150.72 kJ/mol and the optimal cross-linking curing temperature was found to be 142.27°C. The dual-Arrhenius model of the slurry under thermostatic conditions was η_{t} = 228.12 exp (18.50 / T) exp [0.02 exp (7.98 / T) t]. As predicted by this model, the viscosity of the HTPB/CL-20-based composite explosive slurry under thermo-static conditions was consistent with experimental results.
