聚丙烯酸乙酯包覆奥克托金(HMX)的研究

Study on HMX Coating with Polyethyl Arcylate

目的研究聚丙烯酸乙酯对奥克托金（ＨＭＸ）的包覆效果．方法制备聚丙烯酸乙酯乳液，并对ＨＭＸ进行包覆．分别采用光电子能谱分析仪（ＸＰＳ）、透射电子显微镜（ＴＥＭ）、差热扫描热分析仪（ＤＳＣ）、感度测定仪等对包覆ＨＭＸ样品进行表征和分析，得到聚丙烯酸乙酯包覆ＨＭＸ的最佳条件．结果及结论ＨＭＸ的最大包覆度可达６４．０％，包覆膜厚度约０．３μｍ，包覆后的ＨＭＸ热分解温度基本不变，感度有所下降．

Aim To study the coating effects on HMX particles with polyethyl arcylate under different conditions Methods Polyethyl acrylate emulsions were produced, and HMX was coated with polyethyl acrylate XPS, DSC, TEM and sensitivity instrument were used to characterize and analyze the coating effects The optimum conditions of coating HMX with polyethyl acrylate were obtained Results and Conclusion The results show that the maximum coated degree on HMX particles is up to 640%, the thickness of coating membrane is about 03μm,the thermodecomposition temperature of the coated HMX is unchanged basically compared to that of uncoated HMX, and the mechanical sensitivity is lowered slightly
