| 摘 要：為解決CL-20機械感度過(guò)高的缺點(diǎn)，采用機械感度較低的含能材料作為配體與CL-20制成共晶可以有效改善CL-20的感度。以六硝基六異戊茲烷（CL-20）與2，6-二氨基-3，5-二硝基吡嗪-1-氧化物（LLM-105）為原料，通過(guò)溶劑揮發(fā)法制備CL-20／LLM-105共晶材料，利用偏光顯微鏡，X射線(xiàn)衍射（XRD）及差式掃描量熱儀（DSC）對樣品進(jìn)行表征，結果表明：CL-20／LLM-105共晶材料為塊狀粉紅色晶體，與單一CL-20和LLM-105晶體相比形貌有明顯變化。實(shí)驗制得的CL-20／LLM-105共晶材料XRD表明CL-20／LLM-105共晶相比于原料峰值變化較明顯。共晶炸藥的熔點(diǎn)為176.51℃，分解溫度為237.43℃。 |

| Abstract：In order to solve the shortcomings of CL-20 mechanical sensitivity, using the energetic materials with lower mechanical sensitivity as a ligand to form a co-crystal with CL-20 could effectively improve the sensitivity of CL-20. Hexanoyl hexaazaisopentazane (CL-20) and 2,6-diamino-3,5-dinitropyrazing-1-oxide (LLM-105) were used as raw materials. CL-20/LLM-105 co-crystal explosives were prepared by solvent evaporation method. The co-crystal explosives were characterized by polarizing microscope, X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The results showed that the co-crystal explosives were massive pink crystals, a significant change of appearance compared to that of CL-20 and LLM-105 crystals. The XRD of CL-20/LLM-105 co-crystal material showed a significant structure change compared to the the raw material. |
