摘　　要：为了探究烟火药的毫米波辐射,以乳糖/硅粉/硝酸钾为基础配方,少量碳纤维为功能添加剂,结合冷冻干燥制备工艺制备了一种稳定性较好的烟火材料,并对该种材料的燃烧及毫米波辐射性能进行测试分析。结果表明:与传统烟火药制造方法相比,通过冷冻干燥制备工艺制备的烟火药燃烧状态更加稳定;碳纤维的添加提高了烟火药的燃烧温度和毫米波辐射,当硅粉含量为10%、乳糖为30%,添加2%短切长度为1.5mm的碳纤维后,烟火药燃烧温度由770℃增高至950℃,毫米波辐射亮温由500K增高至700K。In order to explore the millimeter wave radiation of pyrotechnic composition,a pyrotechnic material with better stability was prepared by using lactose/silica fume/potassium nitrate as a basic formula,a small amount of carbon fiber as a functional additive,and combining with a freeze-drying process,meanwhile,the combustion and millimeter wave radiation performance of this material were tested and analyzed.The results show that compared with traditional pyrotechnic manufacturing method,the pyrotechnic composition prepared by the freeze-drying preparation process has a more stable combustion state;the addition of carbon fiber improves the combustion temperature of the pyrotechnic composition and millimeter wave radiation.When the content of silicon powder is 10%,lactose is 30%,2%carbon fiber with a chopped length of 1.5mm is added,the combustion temperature of pyrotechnic composition increases from 770℃to 950℃,and the brightness temperature of millimeter wave radiation increases from 500K to 700K.
