    摘要:

    以间苯二酚和甲醛为原料,Na2CO3·10H2O为催化剂,采用溶胶凝胶法,通过RDX在间苯二酚-甲醛树脂(RF)形成的纳米网格中结晶,制备了RDX/RF纳米复合含能材料。用原子力显微镜(AFM),扫描电子显微镜(SEM),X射线粉末衍射仪(XRD),BET比表面积分析仪对其结构进行了表征。结果表明,RF凝胶网格尺寸在几个纳米到几十个纳米之间,RDX/RF凝胶中的RDX晶粒大小平均为38 nm。空白RF气凝胶的比表面积达551.5 m2·g-1, 炸药填充后样品比表面积为142.7 m2·g-1。与同组分的机械混合物相比,RDX/RF复合物的热分解峰提前约25 ℃,机械感度有所降低。

    Abstract:

    Nano-composite energetic materials,hexahydro-1,3,5-trinitro-1,3,5-triazine/resorcinol-formaldehyde (RDX/RF) aerogel,was prepared by crystallization of RDX in the N,N-dimethyllformamide (DMF) within the nano-dimensional pores of resorcinol-formaldehyde (RF) gel matrix. The structures of RDX/RF aerogel were characterized by atomic force microscopy (AFM),scanning electron microscopy (SEM),X-ray powder diffraction (XRD),and BET method. Experimental results show that the grid size formed by RF ranges from several to several decade nm and the mean size of nano-RDX in RDX/RF is 38 nm. The specific surface area for RF aerogel is 551.5 m2·g-1,and for RDX/RF aerogel is 142.7 m2·g-1. Compared to the corresponding values of the mechanical mixtures with the same components,the exothermic peak of RDX/RF aerogel moves down about 25 ℃,and the mechanical sensitivity decreases a little.
