摘要：
The rheological behavior, squeeze process temperature and the relationship between viscosity and temperature during the curing process of Glycidyl Azide Polymer (GAP)/hexanitrohexaazaisowurtzitane (CL-20) based composite explosives slurry were characterized by viscosity measurement technology. The impact of squeeze process temperature on the crystal form of CL-20 in composite explosives was characterized by X-ray diffractometer. Results show that the composite explosives slurry is a kind of pseudoplastic fluid and the optimal squeeze process temperature is 80℃. Moreover, the crystal form of CL-20 in the cured composite explosive is still Ε-type. According to the rheological properties of the slurry, the dual Arrhenius viscosity model of the slurry is ηt=447.5329exp(25.20883/T)exp[0.02922exp(7.18748/T)t] at the condition of constant temperature. When the temperature are 20, 40, 60℃ and 80℃, the viscosity from this model is in good agreement with the experimental results. © 2015, Institute of Chemical Materials, China Academy of Engineering Physics.
