摘要:
采用介观动力学（MesoDyn）模拟方法对比研究了含能增塑剂丁基硝氧乙基硝胺(Bu-NENA)与端羟基聚醚（HTPE）、聚叠氮缩水甘油醚（GAP）共混体系的相结构及其相演变过程和影响因素，用共混实验对Bu-NENA与HTPE、GAP的相容性进行了观察。模拟结果表明:Bu-NENA与HTPE、GAP均具有较好的混溶性，且Bu-NENA与HTPE的混溶性优于Bu-NENA与GAP，与混溶性实验的结果一致。25 ℃条件下，HTPE/Bu-NENA混合体系中Bu-NENA质量分数在50%以下时，HTPE和Bu-NENA混溶性较好；GAP/Bu-NENA混合体系中Bu-NENA质量分数在50%时，GAP和Bu-NENA的混溶性较其他比例时差。但在GAP/Bu-NENA 混合体系中，GAP和Bu-NENA的有序度参数P均较小，接近于0， GAP/Bu-NENA 混合体系混溶性良好；Bu-NENA 的质量分数对GAP/Bu-NENA 混合体系混溶性影响不大。
Abstract:
Phase structure, evolution process and influence factors of blends of energetic plasticizer Bu-NENA, and HTPE or GAP were studied by mesoscopic dynamics simulation (MesoDyn). Compatibility of Bu-NENA and HTPE or GAP was observed by blending test. Simulation results show that Bu-NENA has good miscibility with HTPE or GAP, and the miscibility of Bu-NENA and HTPE is better than that of Bu-NENA and GAP, which is consistent with the results of miscibility test. When mass fraction of Bu-NENA in HTPE/Bu-NENA blends is less than 50% at 25 ℃, the miscibility of HTPE and Bu-NENA is better. When mass fraction of Bu-NENA in GAP/Bu-NENA blends is 50% at 25 ℃, the miscibility of GAP and Bu-NENA is lower than that of other proportions. However, in GAP/Bu-NENA mixed system, the order parameter P?of GAP or Bu-NENA is small and close to zero, and the miscibility of GAP/Bu-NENA blend system is good. Mass fraction of Bu-NENA has little effect on the miscibility of Gap/Bu-NENA blend system.
