摘要/Abstract

摘要： 为解决传统熔铸炸药缺陷多、密度低、力学性能差等问题，将三维(3D)打印技术应用到熔铸炸药的成型制备中。采用自主研发的熔铸炸药3D打印成型原理样机，通过筛选熔铸炸药配方、优化工艺参数，成功打印出含纳米奥克托今和梯恩梯的熔铸炸药药柱。对打印的药柱以及传统浇铸的药柱进行了微观结构、密度和均一性、抗压强度以及爆速等性能表征对比。结果表明：3D打印成型的药柱结构密实，密度为1.65 g/cm³，提高2.0%；抗压强度为5.56 MPa，提高273%；爆速为7 184 m/s，提高2.1%；综合性能明显优于传统浇铸成型的药柱。

Abstract: 3D printing technology is applied in the preparation of melt-cast explosives to solve the problems existing in traditional melt-cast explosives, such as more defects, low density, and poor mechanical properties, etc. An independently developed melt-cast explosive 3D printing principle prototype was used to prepare nano-cyclotetramethylenete-tranitramine (HMX)/2,4,6-trinitrotoluene (TNT)-based melt-cast explosives by selecting the melt-cast explosive formulas and adjusting the process parameters. And the microscopic structures, density, uniformity, compressive strength and detonation velocity of two kinds of melt-cast explosives prepared by 3D printing technology and traditional casting technology are characterized and compared. The results show that 3D printing melt-cast explosives have more compacting internal structures with the density of 1.65 g/cm³, the compressive strength of 5.56 MPa, and the detonation velocity of 7 143 m/s. The density, compressive strength and detonation velocity of 3D printing melt-cast explosive are improved by 2.0%; 273% and 2.1%, respectively, compared to the traditionally prepared melt-cast explosive.
