To investigate the influence of combustion modifiers on the curing of glycidyl azide polymer spherical propellants (GAPSPs), the curing process of the GAPSPs was explored using an isothermal rheological measurement method. The parameters of cure kinetics were solved to further establish a kinetic model for the curing reaction of GAPSPs. The results showed that the curing process of GAPSPs under isothermal conditions conformed to the Kamal and LSK (Lu⁻Shim⁻Kim) models. The model data indicated significant agreement with the experimental data. The influence of four kinds of combustion performance modifiers on the curing process was explored and the results demonstrated that lead phthalate had a catalytic effect on the curing reaction of GAPSPs, whilst oxides of lead and copper, and copper adipate had no influence on the curing reaction.
为研究燃烧改性剂对缩水甘油叠氮聚合物球形推进剂（GAPSPs）固化的影响，采用等温流变测量法探究了GAPSPs的固化过程。求解固化动力学参数以进一步建立GAPSPs固化反应的动力学模型。结果表明，等温条件下GAPSPs的固化过程符合Kamal模型和LSK（Lu-Shim-Kim）模型。模型数据与实验数据高度吻合。探究了四种燃烧性能改性剂对固化过程的影响，结果表明邻苯二甲酸铅对GAPSPs的固化反应有催化作用，而氧化铅、氧化铜和己二酸铜对固化反应无影响。
