| 摘 要： | 以水性聚氨酯(WPU)乳液作为黑索今(RDX)的包覆材料,以撞击感度和热感度作为衡量指标,采用单因素分析法优选出WPU包覆RDX的最佳工艺条件。结果表明:采用单凝聚法包覆RDX,当RDX的粒度为120~300目(铁筛网)、w(WPU)=2.0%(相对于RDX质量而言)和w(阳离子型表面活性剂)=1%(相对于物质总质量而言)时,RDX的包覆效果较好,此时包覆后RDX的撞击感度和热感度降幅较大。

| Abstract: | With waterborne polyurethane(WPU) emulsion as coating materials of RDX,impact sensitivity and thermal sensitivity as evaluation indexes,so an optimal process conditions of RDX coated by WPU were preferred by single factor analysis.The results showed that the coating effect of RDX,which was coated by simple coacervation,was better because the coated RDX had larger reduction amplitude in impact sensitivity and thermal sensitivity when the particle sizes of RDX were 120-300 mesh(by iron sieve),mass fraction of... |
