针对传统镁/聚四氟乙烯(Mg/PTFE)诱饵剂燃烧温度高的问题, 通过添加红磷/氧化铜(P/CuO) 高热剂制备一种具有低燃温薄膜型诱饵材料。将P/CuO 高热剂作为添加剂, 通过工艺与配方设计制成薄膜型箔片, 实现了低温点火与低温稳定燃烧, 并对样品的燃烧速度、辐射强度、燃烧温度等参数进行了测试与分析。研究结果显示, 添加P/CuO 高热剂后, 150 mm×15 mm×0.2 mm的0.5 g箔片, 点火温度可从520 ℃下降到390 ℃; 燃烧温度可从1 500 ℃下降到850 ℃, 且能够稳定燃烧; 大于1.0 W·sr-1持续时间从1.2 s增长到1.6 s。从点火温度、稳定燃烧与辐射的性能分析, 基于P/CuO高热剂改性的Mg/PTFE薄膜型诱饵剂适合于抛散引燃型离散面源诱饵的设计需求。

In order to improve the high combustion temperatures of the traditional PTFE/Mg-based infrared decoy, a discrete array infrared decoy material with a low burning temperature was prepared based on an additive of red phosphorus/copper oxide(P/CuO). Thin foils were made by process and formulation designs. It may be achieved that the foils were ignited at low temperature and burn stably at low temperature. The samples were tested for their relative parameters such as burning rate and the obtained parameters were analyzed. The results show that, after red phosphorus/copper oxide thermite is added therein, the ignition temperature of the foils of 0.5 g thin foils with a dimension of 150 mm×15 mm×0.2 mm is decreased from 520 ℃ to 390 ℃, its burning temperature is decreased from 1 500 ℃ to 850 ℃ and they can burn stably. After the thermite added, their action duration increases from 1.2 s to 1.6 s. However the infrared radiation intensity somewhat decreases. By analyzing its performances such as ignition temperature, burning stability and radiation intensity, the performance of PTFE/Mg-based infrared decoy may be improved by adding P/CuO thermite. It is suitable for the design requirement for discrete array infrared decoy ignited by dispersing.
