摘要:
为了研究2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPyO)基高聚物黏结炸药(PBX)的爆炸性能,拓展其在石油射孔、低易损炸药等相关军民领域的应用,分别以ANPyO为主体炸药,氟橡胶F2311、F2603和丁腈橡胶NBR-26为黏结剂,采用溶液-悬浮-蒸馏法制备了3种ANPyO基PBX炸药,测试其爆速和感度,并采用聚能装药形式进行了爆炸威力和钢靶射孔穿深试验。结果表明,3种ANPyO基PBX的爆速约为7300 m/s,机械感度较低,射孔深度均超过120 mm,高于典型钝感炸药,满足低易损炸药钝感高能的要求;其中丁腈橡胶(NBR-26)样品的射孔深度、入孔直径等参数均优于氟橡胶样品,且爆炸威力中侵彻体积为8701炸药的76.4%,聚能射流较8701炸药更集中。ANPyO基PBX的感度接近典型钝感炸药,爆炸性能接近高能混合炸药,表明ANPyO可以作为一种新型高能钝感含能材料。
Abstract:
In order to study the explosion properties of 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) based polymer binder explosive (PBX), and expand its application in the military and civil fields such as petroleum perforation and low vulnerability explosives, three kinds of ANPyO-based PBX explosives were prepared by solution-suspension-distillation method using ANPyO as the main explosive, fluororubber F2311, F2603 and nitrile rubber NBR-26 as binders and the detonation velocity and mechanical sensitivity were tested. The explosion power and perforation depth of steel target were determined by means of shaped charge. The results show that the detonation velocities of the three ANPyO-based PBXs are about 7300 m/s, the mechanical sensitivity are low,and the perforation depth are all higher than 120 mm, which are higher than that of the typical insensitive explosive and can meet the requirements of low-vulnerable explosives with insensitivity and high energy. The perforation depth and hand-hole diameter of NBR-26 sample are better than those of the fluororubber samples. The penetrating volume of NBR-26 sample is 76.4% of 8701 explosive in explosive power test, and the shaped charge jet is more concentrated than that of 8701 explosive. The mechanical sensitivity of ANPyO-based PBX is close to that of the typical insensitive explosive, and its explosion properties is close to that of the high-energy mixed explosive, indicating that ANPyO can be use as a new type of high-energy insensitive energetic material.
