摘要:
为研究纳米铜Cu对丁羟推进剂性能的影响，制备了含纳米Cu的推进剂，作为比较，同时制备了含有纳米CuO的推进剂和空白推进剂试样。采用SEM和TG-DSC表征推进剂的形貌和热性能，采用靶线法测试推进剂的燃速，并拍摄推进剂的燃烧火焰。TG-DSC结果表明，纳米Cu和纳米CuO主要影响AP的高温热分解阶段，但是纳米CuO比纳米Cu对推进剂的热分解具有更好的催化作用。纳米Cu可使AP的终止热分解温度降低67.0 ℃，使推进剂的终止热分解温度降低24.7 ℃。燃速测试结果表明，纳米Cu和纳米CuO均可提高推进剂的燃速，但是纳米Cu对推进剂燃速的改善效果更显著。加入纳米Cu和纳米CuO后，推进剂在燃烧过程中均出现蓝色火焰。
Abstract:
In order to study effects of nano Cu on performances of HTPB propellant, the propellant containing nano Cu was prepared. Propellant containing nano CuO and blank samples were also prepared. SEM and TG-DSC were used to characterize the structure and thermal performance of the propellants respectively. Their burning rates were measured by strand burner method. Combustion flames were taken by camera. TG-DSC result shows that nano Cu and nano CuO show good catalyzing effect on thermal decomposition of AP in the high temperature phase. But nano CuO has a better catalytic effect on the decomposition of propellant than nano Cu. Addition of Nano Cu enables to decrease the end decomposition temperature of AP by 67.0 ℃ and reduce the end decomposition temperature of propellant by 24.7 ℃. The results of burning rate show that nano Cu has more remarkable effect on improving burning rate of propellants than nano CuO. Moreover, blue flame appears in the combustion process of propellant containing nano Cu and nano CuO.
