摘要
研究了6种含能羟基吡啶铅、铜盐对RDX-CMDB推进剂燃烧性能的影响。研究发现:含硝基的羟基吡啶铅盐具有较好的催化燃烧作用和降低压强指数的能力,尤其是2-羟基-3,5-二硝基吡啶铅盐,其催化效率最高,含能羟基吡啶铜盐的催化作用不明显。2-羟基-3,5-二硝基吡啶铅盐和4-羟基-3,5-二硝基吡啶铅盐催化效果产生差异的原因是两者热分解历程不同,最后生成的碳量不同。
The effect of six kinds of energetic lead or copper salts of hydroxypyridines on the combustion properties of RDXCMDB propellant was investigated. It is discovered that the lead salts of hydroxypyridines containing nitro groups possess better catalytic effect and ability to reduce pressure exponent for the propellant, especially for lead salt of 2hydroxy3,5dinitropyridine, which has the highest catalytic efficiency. The catalysis of the energetic copper salts of hydroxypyridines in the propellant is not obvious. The catalysis difference between lead salt 2hydroxy3,5dinitropyridine and 4hydroxy3,5dinitropyridine is due to their different thermal decomposition mechanism and different carbon content formed in the decomposition process.
