摘要
以传统镁/聚四氟乙烯配方的红外诱饵剂为基础，以燃烧时间、燃烧温度和红外辐射强度作为考核参数，对以红磷和氧化铜作为功能添加剂的薄膜型低燃温红外诱饵剂进行了实验研究。以镁、聚四氟乙烯、红磷和氧化铜的导热性系数作为参量，综合比较了不同配方对反应速度的影响，以及对燃烧温度、辐射强度的影响。研究结果显示，以红磷和氧化铜为功能添加剂可以改善低火焰温度条件下的燃烧稳定性。当红磷含量为25%，镁粉含量为25%，氧化铜含量为10%~15%，聚四氟乙烯含量为35%~40%时，0.03 cm厚燃烧反应薄膜的燃烧最为稳定，燃烧时间大于3 s，辐射强度在1.5 W/sr左右，燃温为800℃左右。
This research builds upon the traditional composition of the infrared flare （Magnesium/Teflon, MT）, and red phosphorus and copper oxide were chose as functional additives, a composition of thin-film infrared flare with low flame temperature was optimized based on its burning time, flame temperature and radiation intensity. In addition to respective conductivity of the material component were chosen as parameters, combustion rates of different prescriptions were analyzed based on their conductivity, and an indication of the impact of combustion temperature and radiation intensity was fiven. The results of the study show that red phosphorus and copper oxide added can improve combustion stability under lower flame temperature. When the content of red phosphorus was 25%, magnesium powder was 25%, copper oxide was 10%-15%, teflon was 35%-40%, the combustion of the 0.03 cm-thick thin film was most stable, and its combustion time is greater than about 3 s, the most radiation intensity is 1.5 W/sr, the flame temperature is about 800℃.
