摘　　要：为了研究纳米铝粉的加入对混合炸药爆轰能量的影响,设计了不同含量的RDX基含纳米铝混合炸药配方,并采用直接混合造粒工艺制备炸药样品。通过爆热测试和分析,发现混合炸药的爆热随着铝含量的增加而增加;对于RDX基炸药,用纳米铝粉替代微米铝粉,不能提高炸药的爆热;采用与微米铝适当级配,可提高炸药的爆热;当炸药中铝粉总含量为35%,其中纳米铝含量为5%时,爆热值较大,比同含量微米铝炸药提高5.83%。研究结果认为,适当调整混合炸药中纳米铝的含量,可有效提高炸药的爆轰能量。In order to investigate the influence of nanometer aluminum on the detonation energy of RDX-based explosive, the formula with diverse nanometer aluminum content was designed, and the sample was prepared by immediate mixing technology. Through measuring the explosion heat, it can be found that explosion heat of RDX-based explosive increased with the content of aluminum increasing, while didn’t increase with replacement of micrometer aluminum by nanometer aluminum. If blending 30% micrometer aluminum with 5% nanometer aluminum, explosion heat of RDX-based explosive can be increased by 5.83% comparing with formula containing 35% micrometer aluminum. The results show that detonation energy can be effectively enhanced with proper nanometer aluminum content.
