摘要本文将机械研磨法制备的纳米CuO应用于AP-CMDB推进剂中。采用热重/差示扫描量热法研究了纳米CuO对AP-CMDB推进剂的催化性能。采用线燃烧器法测定了纳米CuO改性AP-CMDB推进剂的常压燃烧速率。实验结果表明，纳米CuO的存在对AP-CMDB推进剂的热分解和燃烧有明显的促进作用。与空白推进剂相比，AP-CMDB推进剂的热分解温度降低。同时，AP-CMDB推进剂在大气压下的燃烧率提高了约22.2%。纳米CuO对AP改性双基推进剂的催化活性上级优于本体CuO，这为纳米CuO在AP改性双基推进剂中的应用奠定了基础。
ABSTRACT In this work, nano-sized CuO prepared by mechanical grinding method was applied to the AP-CMDB propellant. The catalytic activity of nano-sized CuO on AP-CMDB propellant was investigated by thermogravimetric analysis/differential scanning calorimetric techniques. The combustion rates at atmospheric pressure of AP-CMDB propellant modified by nano-sized CuO were measured by strand burner method. The experimental results show enhancements on the thermal decomposition and combustion of AP-CMDB propellant in the presence of nano-sized CuO. Compared with blank propellant, the thermal decomposition temperature of AP-CMDB propellant shifts downward. Simultaneously, the combustion rate of AP-CMDB propellant at atmospheric pressure increases by about 22.2%. Encouragingly, the catalytic activity of nano-sized CuO on AP-CMDB propellant is superior to that of the bulk CuO, which leads to a potential application of nano-sized CuO in the AP-CMDB propellant.
