| 摘 要： | 分别以丙烯腈-苯乙烯共聚物(AS),氟橡胶(F2311),聚氨酯弹性体(Eatane5701)和水性聚氨酯(WPU)为包覆原材料,采用水悬浮包覆法、喷涂法和破乳法包覆黑索今(RDX)。对包覆颗粒的进行了高效液相色谱(HPLC)分析,测定了RDX溶出量,计算了粘结剂对RDX的包覆度。对比了HPLC法与扫描电子显微镜(SEM)和X射线光电子能谱法(EDS)的表征效果。结果表明:以AS为包覆材料,喷涂法得到的包覆颗粒,包覆效果最好,SEM观测到包覆比较致密,与RDX表面有良好的物理接触,EDS没有检测到包覆不完全的情况,HPLC评价得到的包覆度为96.24%。

| Abstract: | Coated RDX were prepared by water suspension coating method, spray coating method and demulsification method, using acrylonitrile-styrene (AS) copolymer, fluoro rubber (F2311), polyurethane elastomer (Estane5701) and waterborne polyurethane (WPU) as coating raw materials, respectively. The high performance liquid chromatography (HPLC) determination of coated particles, quantitative determination of the dissolution quantity of RDX and calculation of the adhesive coated degree of RDX were carried out. The characterization efficacy of HPLC, scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS) was compared. Results show that using AS as raw material, the coated particles obtained by spray coating method have dense coating and perfect physical contact with the surface of RDX. The situation of incomplete coating is not detected by EDS. The degree of coverage obtained by HPLC is 96.24%. |
