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/cm^3,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。
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 meltcast 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 kindsof 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/cm^3,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.
