    摘要:

    采用粘度测试技术研究了聚叠氮缩水甘油醚(GAP)/六硝基六氮杂异伍兹烷(CL-20)基混合炸药药浆的流变特性、挤注工艺温度和固化过程中温度与粘度的关系。用X射线衍射仪测试工艺温度对其混合炸药中CL-20的晶型的影响。结果表明, 混合炸药药浆为假塑性流体, 80 ℃为最佳挤注工艺温度, 固化后混合炸药中的CL-20仍为ε晶型。根据药浆的化学反应流变特性, 在恒温条件下采用双阿伦尼乌斯方程建立的粘度模型为ηt=447.5329exp(25.20883/T)exp[0.02922exp(7.18748/T)t]。在20, 40, 60, 80 ℃时, 该模型的理论预测粘度与实验结果吻和良好。

    Abstract:

    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.
