| 摘 要： | 研究了纳米级碳酸铅对ＮＥＰＥ推进剂燃速压力指数的影响。采用ＤＳＣ分析了纳米级碳酸铅与ＮＥＰＥ推进剂主要组分硝酸酯的相容性以及对推进剂固化反应的催化作用和对高氯酸铵、硝胺常压热分解的催化作用，并利用恒压静态燃速仪测试了推进剂在４ＭＰａ￣１１ＭＰａ的燃烧速度和燃速压力指数。发现纳米组碳酸锅表现出与硝酸酯良好的相容性，对推进剂的固化反应和硝胺的热分解均有很强的催化作用，对高氯酸铵的热分解则没有明显的影响

| Abstract: | The effects of nanometer PbCO 3 on combustion behavior of NEPE solid propellant have been studied The compatibility of nanometer PbCO 3 and nitrate ester , as well as the effects of nanometer PbCO 3 on the curing reaction and on the thermal decomposition behaviors of ammonium perchlorate and nitroamino compounds were studied by Differential Scanning Calorimetry (DSC) It was found that nanometer PbCO 3 exhibited good compatibility with nitrate ester which had observable acceleration on the thermal decomposition of nitroamino compounds and on the curing reaction but little effect on ammonium perchlorate When nanometer PbCO 3 was applied to NEPE solid propellant, the pressure exponent were effectively brought down to 0 54 and 0 52 with which content was 1% and 2%respectively |
