The interfacial strength between explosive crystal and binder usually plays a key role in exhibiting excellent mechanical properties of composite explosives. In this paper, high energetic crystal octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine (HMX) was coated by the typical binder cis‐1,4‐polybutadiene rubber (BR), then two silane coupling agents were added to the composite particles to enhance the interface strength. The results showed that the BR binder modified by silane coupling agent is easier to spread on the surface of HMX crystal, and form a good coating effect. In the mechanical properties test of composite particles, (3‐Aminopropyl) trimethoxysilane significantly improved the tensile and compressive strength of HMX/BR based composite particles, while 3‐(Triethoxysilyl) propionitrile decreased the mechanical properties of the composite particles.

顺式1,4-聚丁二烯橡胶与HMX晶体之间的界面性质的改善

炸药晶体与粘合剂之间的界面强度通常在发挥复合炸药优异的机械性能方面起关键作用。在本文中，高能晶体八氢-1,3,5,7-四硝基-1,3,5,7-四唑辛（HMX）涂有典型的粘结剂cis-1,4-聚丁二烯橡胶（BR），然后将两种硅烷偶联剂添加到复合颗粒中以增强界面强度。结果表明，硅烷偶联剂改性的BR结合剂更易于在HMX晶体表面上铺展，并形成良好的包覆效果。在复合颗粒的机械性能测试中，（3-氨基丙基）三甲氧基硅烷显着提高了HMX / BR基复合颗粒的拉伸和压缩强度，
