摘要:

为满足微型爆炸元件中含能材料集成化的需求,以RDX、HMX 为研究对象,采用溶剂/非溶剂重结晶和软模板方法相结合,得到片状的RDX 和HMX 晶形。用扫描电镜(SEM) 分别观察其表面形貌,发现RDX 片有两种结构:六边形RDX 片晶厚度约3 μm,长在20 ~50 μm 范围内;四边形RDX 厚度约1 μm,长在10 ~50 μm 范围内;HMX 片晶为长方形,厚度小于1 μm,长在3 ~10 μm 范围内。对3 种含能片进行撞击感度和热分解性能测试,结果表明:片状含能材料的撞击感度比类球形含能材料高,但分解放热峰值基本不变化。

Abstract:

Flaky RDX and HMX are prepared by using solvent/ non-solvent recrystallization and soft template method in order to meet the integration requirements of energetic material in miniature explosive element. Its surface appearance is investigated by SEM. The result shows that the thickness and length of hexagonal flaky RDX crystal are about 3 μm and 20 -50 μm, respectively; the thickness and length of quadrilateral RDX flaky crystal are approximately 1 μm and 10 -50 μm, respectively; the thickness and length of rectangle HMX flaky crystal are less than 1 μm and 3 -10 μm, respectively. The impact sensi- tivity and thermal decomposition of flaky energetic material crystal are tested. The test results show that the impact sensitivity of flaky energetic material crystal is increased, but its exothermal peak value is not changed compared with near-spherical crystal.
