摘要:为规避使用自燃型面源红外诱饵材料，并解决燃烧型面源红外诱饵材料的燃烧不稳定和长波段辐射强度较弱的问题，采用传统的镁/聚四氟乙烯(Mg/PTFE) 红外诱饵剂，在一定的成型工艺下形成了一种面源红外诱饵材料，并通过加入四氯化钛（TiCl4）来提高8～14μm波长范围的辐射强度，添加红磷/氧化铜（P/CuO）高热剂来降低点火温度、提高燃烧稳定性。对样品的燃烧稳定性、辐射强度和装药作用后红外云团进行了测试，结果表明，红外面源诱饵材料在引燃后能保持较为稳定的燃烧状态，空中引燃抛撒后形成了一定面积的有效红外干扰云，并且上升时间、持续时间、辐射强度和辐射面积满足面源红外诱饵的使用需求。较自燃型面源红外诱饵，该型诱饵形成的红外干扰云具有更加良好的整体聚集性和气动悬浮性。
Abstract:To avoid the use of spontaneous combustion type of surface source infrared decoy material and solve the problems of combustion instability and weak long-wave radiation intensity of burning surface source infrared decoy materials, one kind of surface-type infrared decoy was fabricated with traditional PTFE/Mg-based infrared decoy by a special process. Meanwhile, titanium tetrachloride was added to increase the infrared radiation of 8～14μm, red phosphorus/copper oxide (P/CuO) was added to lower the ignition temperature and improve combustion stability. The combustion stability, radiation intensity and infrared cloud after charging were tested. The results show that the surface-type infrared decoy can maintain a stable burning state after ignition, the infrared interference cloud with certain effective area can be formed after dispersing surface-type infrared decoy in air, the rise time, duration time, infrared radiation intensity and radiation area can meet the usage needs. The infrared interference cloud formed by combustion of this type of decoy has better overall aggregation and aerodynamic suspension than that formed by spontaneous combustion type of surface source infrared decoy.
