摘　　要：黑索今(RDX)属于非补强性填料,与黏结剂的结合效果差,当其受到载荷作用时,黏结剂与RDX间的界面结合容易被破坏,黏附失效而导致黏结剂从固体颗粒表面脱离,容易出现产品缺陷,影响产品性能。为深入了解RDX为基的高聚物粘结炸药(PBX)压制过程的损伤形成规律,对以RDX为基的两种炸药配方进行压制实验,研究了压制条件及黏结剂选择等因素对炸药成型性能的影响规律。结果表明:控制降温速率、采取分段保压的方法可有效抑制炸药件内部损伤的形成;选择适当的黏结剂对提高RDX为基的PBX炸药压制件的成型性能具有重要作用,丙烯腈丙烯酸酯黏结剂与RDX之间的黏附性能要比F2311好,该炸药配方压制出的炸药柱各方面性能良好,而以F2311为黏结剂的炸药配方压制出的炸药柱不能满足使用要求,存在较大的质量缺陷。The interfaces between RDX and binder are easily debonded because of improper bonding choice and pressing process conditions.The RDX-based polymer bonded explosives（PBXs） with F2311 and acrylonitrile-acrylate respectively were pressed by steel to study the pressing damage mechanisms.Results show that proper pressing conditions decrease the pressing damage in the shaping samples.The proper bonding improves the properties of the shaping samples.When acrylonitrile-acrylate is used in shaping RDX-based explosives,the properties of the samples are better than that of samples with F2311.
