摘要
采用静电喷雾技术制备了以氟橡胶(F2604)为包覆材料的F2604/AP(高氯酸铵)复合物。通过对所制备的复合颗粒进行扫描电镜(SEM)、傅里叶变换红外光谱(FTIR)、差示扫描量热(DSC)及机械感度检测分析,研究超细AP复合物包覆效果、热分解特性及感度特性。结果表明,由静电喷雾技术所制备的复合含能材料颗粒尺寸小、分布均匀、包覆效果良好;与AP样品颗粒相比,AP复合含能材料样品颗粒的放热峰温度有大约70~80℃的延后,热分解温度有所提高,有利于其热稳定性;随着F2604含量的增加,F2604/AP复合颗粒的机械感度逐渐降低,F2604的添加可以有效降低AP的机械感度。
F2604/AP composite with fluororubber F2604as cladding material was prepared by electrospray method.SEM,FTIR,DSC and mechanical sensitivity tests wee conducted to investigate coating effect,thermal decomposition cha-racteristics and sensitivity of ultrafine AP composites.Results show that the composite prepared by electrospray method has small uniform sizes"with good coating performance.Compared"with that of AP particles,exothermic peak of the composite particles has a delay of70-80丈leading to increased thermal decomposition temperature and thermal stability.Mechanical sensitivity of F2604/AP composites decreased with the increase of F2604.Addition of F2604could reduce mechanical sen-sitivity of AP.
