摘要:
采用溶液-水悬浮法,通过控制料液质量比、包覆温度、搅拌速度等工艺参数制备了纳米RDX基PBX。使用TG/DSC同步热分析仪研究其热分解特性,并依据GJB 772A—1997分别对其撞击感度和摩擦感度进行了测试。结果表明:与微米RDX基PBX相比,纳米RDX基PBX的DTG峰温提前约0.6 ℃,活化能降低约2.5 kJ/mol;纳米RDX基PBX撞击感度H50为46.3 cm,微米RDX基PBX H50为29.8 cm,相对降低55.4%;纳米RDX基PBX摩擦感度比微米RDX基PBX相对降低21.1%。
Abstract:
Nano-RDX based polymer bonded explosive (PBX) was prepared using solutionwater slurry method by controlling the reaction conditions such as ratio of water to material, reaction temperature and stirring speed. Thermal decomposition characteristics of nanoRDX based PBX were analyzed by a TG/DSC simultaneous thermal analyser,and its impact sensitivity and friction sensitivity were tested according to GJB772A—1997. Results show that, compared to those of micronRDX based PBX, DTG peak temperature of nano-RDX based PBX shifts 0.6 ℃ upwards, and its activation energy decreases by 2.5 kJ/mol. Impact sensitivity H50 of nanoRDX based PBX is 46.3 cm, decreasing by 55.4% comparing with micron-RDX based PBX, H50of which is only 29.8 cm. Friction sensitivity of nano-RDX based PBX has a decrease of 21.1% compared to micron-RDX based PBX.
