TATB基高聚物粘结炸药及其粘结剂的玻璃化温度与DMA测量频率关系的研究
Study of Relationships between Glass Transition Temperatures
and Test Frequencies on TATB-based PBXs and Their Binders Using DMA
摘要
Abstract
Relationship between test frequency and glass transition temperature was studied for four TATB-based PBXs and their binders (fluoropolymers),by using dynamic mechanical analysis (DMA) method. Results showed that of the four fluoropolymers,F2314,F2311,F2463 and F2603,only F2314 has an apparent secondary transition,which is ascribed to the fact that there are much more C—Cl bonds attached to a F2314 molecule. Meantime,the activation energies of the PBXs and their binders were calculated from the relationship between test frequency and glass transitiontemperature for the PBXs and their binders. It followed from comparisons between the activation energies of the PBXs and their binders that present of high contented TATB particles in the PBX may cause an obvious limitation in conformational movement of polymeric segment. A simple model,which had been confirmed by SEM photos of some PBXs, was presented to explain this phenomenon.关键词
