摘要：

To study the rheological properties and to cure the reaction process of branched polyglycidyl azide（B-GAP）-based propellent，the slurries were tested by rheological research methods，and the changes of viscosity with shear rate and modulus with time at 50，55，60 ℃ and 65 ℃ were studied. The results indicate：B-GAP propellant slurry has a shear thinning properties and belongs to pseudoplastic non-Newtonian fluid；The curing reaction rate of the propellant slurry increases as the curing reaction progresses，reaching a maximum value when the curing degree is 0.3，and then the reaction rate begins to decrease until zero；Temperature has a great influence on the kinetics of propellant curing reaction. Within a certain temperature range，the peak value of the curing reaction rate increases with the increase of temperature，and the maximum value of storage modulus decreases with the increase of temperature；Based on the power law equation and Arrhenius equation，the constitutive equation and curing kinetic reaction equation of B-GAP slurry was obtained. © 2022 Institute of Chemical Materials, China Academy of Engineering Physics.
