【摘要】 采用扫描电镜(SEM),X射线光电子能谱(XPS)和显微红外光谱(MIR)技术,实验研究了树形键合剂(DBA)对RDX晶体的包覆性能及其界面相互作用机理。结果表明,树形键合剂可以在RDX表面形成一层粘流状的吸附层,具有良好的包覆性能,显微红外光谱的数据也表明了键合剂与RDX的NO2基团形成氢键,从而证实了DBA作为RDX键合剂的有效性。更多还原

【Abstract】 A dendritic bonding agent (DBA) that can coat RDX filler successfully is reported. The coating properties are characterized by SEM, XPS and Micro infrared. DBA forms a layer of viscous film on the surface of RDX; the coating degree can be up to 100% from XPS analysis. Micro infrared analysis indicates that H-bond is formed between DBA and NO2 groups, and it proves that DBA is available for coating RDX.更多还原
