2,6-二氨基-3,5-二硝基吡啶-1-氧化物为基的耐热混合炸药性能

分别制备了以2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPyO)为基,加入氟橡胶F2311、氟橡胶F2603及其两种混合物黏结剂和增塑剂组成的三种耐热混合炸药,进行了耐热性、感度、成型性、爆炸能量和破甲威力性能测试。结果表明,三种以ANPyO为基耐热炸药有良好的耐热性能,可以在200～250℃温度条件下使用;成型性能良好;机械感度比较接近,均低于单质ANPyO,撞击和摩擦感度最小值分别为10%和24%;爆速和破甲性能均高于以PYX基的混合炸药,爆速提高约400m.s-1,破甲深度提高约30mm。

Performance of 2,6-Diamino-3,5-dinitropyridine-1-oxide-based Heat-resistance Composite Explosives

Three heat-resistant composite explosives (ANPyO(F_(2311)),ANPyO(F_(2603)),ANPyO(F_(2311):F_(2603)=1:1)) composed of 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO),polymer binders and plasticizer were prepared. The performance tests were conducted by measuring the heat resistance,formability,sensitivity,explosion energy and penetration power. Results show that three ANPyO-based heat-resistant composite explosives have better heat resistance and processability,which indicates that three composite explosives can be used in the temperature range of 200-250 ℃,and the mechanical sensitivities of three composite explosives are vicinal and lower than that of ANPyO individual explosive,and the minimum values of impact and friction sensitivity are about 10% and 24%,respectively. The detonation velocity and breaking armour of three composites explosive are higher than that of PYX-based composite explosive,and detonation velocity is increased by about 400 m·s~(-1),and depth of breaking armour is increased by about 30 mm.
