摘要:
针对传统乳化炸药高能敏感问题，采用悬浮聚合法设计了一种利用聚甲基丙烯酸甲酯（PMMA）包覆硼粉的含能微囊。利用该硼粉型含能微囊作为添加剂制备了乳化炸药。通过激光粒度分析仪和扫描电镜，对硼粉型含能微囊的微观结构进行了表征；利用同步热分析仪、爆热弹和空中爆炸测试系统，研究了硼粉型含能微囊对乳化炸药热稳定性、爆热以及冲击波参数的影响。实验结果表明：硼粉能够提高乳化炸药的冲击波特征参数和爆热，其中，冲击波峰值压力和爆热分别提高了29%和42%以上；而微囊包覆技术可以增加含硼乳化炸药的初始分解温度和活化能，改善其热稳定性。利用微囊包覆含能添加剂的方法，可以在不影响乳化炸药安全性的前提下提高其做功能力，改善工程爆破和爆炸加工效果，为研制安全高能乳化炸药提供了新的思路。
Abstract:
Aiming at the high energy sensitivity of conventional emulsion explosives, a kind of energetic microcapsule using polymethyl methacrylate to encapsule boron powders was designed by suspension polymerization method. A kind of emulsion explosive containing boron powder energetic microcapsules was prepared. Microstructures of boron powder energetic microcapsules were characterized by a laser particle size analyzer and a scanning electron microscopy. Effects of boron powder energetic microcapsule on thermal stability, detonation heat, and shock wave parameters of emulsion explosives were investigated using a simultaneous thermal analyzer, a detonation heat bomb and an air blast testing system, respectively. Experimental results show that boron powder could improve the shock wave characteristic parameters and detonation heat of emulsion explosives, and the peak shock wave pressure and detonation heat increase by more than 29% and 42%, respectively. Furthermore, the microcapsule coating technology would significantly increase the initial decomposition temperature and the activation energy of emulsion explosive containing boron powders, and improve the thermal stability. The method of using microcapsules to encapsulate energetic additives can improve the working capacity of emulsion explosive without affecting its safety, and improve the outcomes of engineering blasting and explosive processing, which provides a new idea for the development of safe high-energy emulsion explosives.
