以环氧丙烷和氧杂环丁烷的衍生物为母体,通过引入不同的含能基团而获得的一类新型含能黏结剂,在推进剂、火炸药和烟火剂中具有良好的应用前景,是近年来高能固体推进剂的研究热点之一。本研究从结构与性能关系的角度综述了不同含能基团对其均聚物的密度、生成热、熔点以及力学等性能的影响。通过对比分析发现,此类含能黏结剂在PBX炸药中同样具有良好的应用前景。
In recent years, much attention was paid to new energetic binders used in high-energy solid propellants, which were synthesized from ring opening of oxirane and oxetane with different energetic groups. The relationships between the different energetic groups and physical and chemical properties, such as densities, heats of formation, melting point and mechanical properties,were reviewed. Finally, the possibility of this type of energetic binders used in PBX explosives was discussed by comparing their strongpoint and disadvantages.
