摘　　要：采用螺压工艺研究了Pb、Cu、CB单组分、双组分和3组分催化剂在改性双基推进剂中的催化性能,获得了燃速28-30mm/s（20℃,14MPa）,﹣55℃、20℃、70℃3种温度时,8-10MPa、10-14MPa、14-17MPa、17-20MPa压力指数基本相同的双基推进剂,并且在低温、常温、高温条件下平台压力范围均为8-20MPa,实现了该推进剂﹣55-70℃使用的宽温性能。The catalytic property of single component, two-component and three- component ofPb, Cu and CB on CMDB propellant was studied by screw extrusion process. The burning-rate pressure exponent of the propellant at 8-10MPa, 10-14MPa, 14-17MPa and 17-20MPa is basically the same with burning rate 28-30mm/s （20℃, 14MPa）. The propellant with same platform at 8-20MPa in temperature -55℃, 20℃ and 70℃ was obtained, which realized the wide temperature range performance in -55-70℃ of the propellant.
