摘要: 为探讨水性红外迷彩在篷布上的实际应用,从颜填料和助剂两方面研制了发射率为0.589、0.761和0.953,颜色分别为土黄、翠绿和墨绿色的红外迷彩涂层材料;采用紫外-可见光-近红外分光光度计、红外热像仪、SEM、TG-DTG等手段对该红外迷彩涂料的可见光-近红外隐身性能、红外隐身性能、表面形貌、热稳定性、柔韧性等其他性能进行表征。结果表明:研制的红外迷彩可见光-近红外反射光谱曲线与背景相似,红外热图分割效果良好,涂层表面形貌、稳定性、柔韧性等性能满足篷布使用要求。Abstract: In order to investigate the use of water-based infrared camouflage coatings on tarpaulin, coatings with different infrared emissivities(0.589, 0.761 and 0.953) and different colors(khaki, emerald and dark green) were developed from fillers and auxiliaries; UV-Vis-NIR spectrophotometer, infrared thermal imager, SEM, and TG-DTG were used to characterize the performances of infrared camouflage coatings such as visible light-near infrared stealth, infrared stealth, surface topography, heat stability etc. The research results show that the visible light-near infrared reflectance spectra of infrared camouflage tarpaulin are similar with the background, the partition effectiveness of infrared map is good, and the usage requirements are met by the performances of the surface topography, heat stability and flexibility.
