氟橡胶粘结耐热炸药界面作用的红外光谱分析

Interface Study on FT-IR of Heat-Resistant Explosive Coated by Fluororuber

用傅立叶红外光谱(FT-IR)研究了由氟橡胶包覆几种耐热炸药的界面作用。实验发现在氟橡胶的作用下耐热炸药供电子基团的吸收峰均产生位移,这说明氟橡胶与耐热炸药界面存在相互作用。主体炸药的分子结构不同,界面上各基团相互作用的强弱不同,产生吸收峰位移的方向也不同。

In this paper, Fourier Transform Infrared Spectroscopy (FTIR) is utilized to analyze the interaction of interface between several heatresistant explosives and Fluororuber. It is found in the test that the wave peak move of donor groups resulting from the strong electronattracting groups in Fluororuber illustrates the interactions existing in the interface. The direction of wave peak move comes from the difference of explosive structure and interaction from acidbase groups.
