摘要:
为了降低高能炸药六硝基六氮杂异戊兹烷(CL-20)的机械感度,采用超声辅助乳液法制备了球形六硝基六氮杂异戊兹烷/二硝基甲苯(CL-20/DNT)复合物;研究了超声时间和放置时间以及表面活性剂的种类和用量对乳液稳定性和复合物形貌的影响;通过光学显微镜和扫描电镜(SEM)对CL-20/DNT复合物的形貌和尺寸进行了表征;采用X射线衍射光谱(XRD)、傅里叶红外分析(FTIR)对其结构进行了表征;采用差示扫描量热分析(DSC)对其热分解性能进行了测试;采用特性落高法测试了其机械感度。结果表明,在以吐温-80为表面活性剂、用量为炸药总质量的1.87%、超声时间不低于10 min以及放置时间不超过24 h的条件下,所制备的球形CL-20/DNT复合物形貌尺寸较好,粒径分布较窄,中位粒径为1.88 μm,表面光滑;与原料CL-20相比,球形CL-20/DNT复合物的热分解温度提前了27.05℃,转晶峰消失;其特性落高由13.0 cm升至68.5 cm,感度明显降低。
Abstract:
To reduce the mechanical sensitivity of high-energy explosive 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane(CL-20), the spherical CL-20/dinitrotoluene (DNT) composites were prepared by an ultrasonic-assisted emulsion method. The effects of ultrasound time, placement time and the type and dosage of surfactant on the stability of the emulsion and morphology of the composites were studied. The morphology and size of the CL-20/DNT composites were characterized by optical microscope and scanning electron microscope(SEM). The structures of the CL-20/DNT composites were tested by X-ray diffraction spectrum(XRD) and Fourier transform infrared (FTIR), and the thermal decomposition properties were tested by differential scanning calorimetry(DSC). The mechanical sensitivity was tested according to the characteristic drop height method. Results indicate that under the condition of tween-80 as surfactant and the dosage is 1.87% of the total mass of explosive, the ultrasonic time is no less than 10 min and the placement time is no more than 24 h, the prepared spherical CL-20/DNT composite has a better morphology size and a narrower particle size distribution, the median particle size is 1.88 μm and the surface is smooth. Compared with the raw material CL-20, the thermal decomposition temperature of the spherical CL-20/DNT composite is advanced by 27.05℃, and the crystal transition peak disappears. Its characteristic drop height increases from 13.0 cm to 68.5 cm, showing that the sensitivity is obviously reducod.
