摘　　要：为了研究顺丁橡胶BR和氟橡胶F2603对三乙烯二铵高氯酸铵复盐DAP-4的表面包覆的影响,采用溶剂挥发直接法工艺制备了含不同黏结剂的DAP-4样品,借助表面性能、扫描电镜、X光电子能谱和机械感度试验评价了两种黏结剂对DAP-4的包覆效果和安全性。结果表明:BR在DAP-4粉末表面形成有效铺展,F2603与DAP-4粉末表面的界面相互作用强;包覆后的DAP-4晶体颗粒形貌表面边界棱角模糊且粗糙,DAP-4/BR样品的包覆度小于DAP-4/F2603样品,且黏结剂BR和F2603包覆DAP-4样品的机械感度降低。这有利于DAP-4化合物的应用及推广。In order to study the influence of the binder butadiene rubber BR and fluororubber F2603 on surficial coating of DAP-4,the DAP-4 samples containing different binders(BR or F2603)were prepared by direct solvent volatilization process.Coating outcome and safety of the samples were evaluated by surface performance test,scanning electron microscope,X-ray photoelectron energy spectrum and mechanical sensitivity test.The results show that BR could form the efficient spreading in the surface of DAP-4 powder,the interface action between the surface of F2603 and DAP-4 is stronger than that between the surface of BR and DAP-4.The surface edges and corners of the coated DAP-4 crystal particle are fuzzy and rough.The coating degree of DAP-4/BR sample is less than that of DAP-4/F2603.And the mechanical sensitivity of DAP-4 coated by BR or F2603 decreases,which is beneficial for the application and promotion of DAP-4.
