摘要：

以水性聚氨酯为粘合剂,掺杂Al和La的ZnO为填料,配以其它助剂制成了红外隐身涂料,应用在帐篷织物表面,探究涂层厚度以及填料含量对红外发射率的影响,并研究了导热系数和红外隐身性能之间的关系。研究发现,涂层厚度和填料含量对涂层织物的红外发射率有着显著的影响。当填料质量分数为70%时,得到的帐篷涂层织物的红外发射率可降至0.622,调节填料含量和涂层厚度,可以的得到红外发射率在0.622~0.932之间的帐篷涂层织物。此外,发现导热系数对红外隐身性能也有一定的影响,红外隐身性能随着导热系数的增加而提高。通过调节填料含量和涂层厚度制作不同红外发射率的涂层帐篷织物,放在不同背景下拍摄红外热成像图,发现涂层在不同的环境中均具有良好的伪装能力。

Abstract:

To increase the survival ability of military supplies, expedite the usage of infrared stealth material, Al, La doped ZnO was used as filler to prepare infrared stealth coating and coated on tent fabrics. The influences of filler content and film thickness on infrared emissivity were studied in detail. The relationship between heat conduction and infrared emissivity was also studied. The infrared emissivity decreased with the increase of the thickness and content of coating filler. The infrared emissivity of coating tent fabric can decrease to 0.622 when filler mass content is 70%. The tent fabrics with infrared emissivity between 0.622 and 0.932 can be obtained by changing the filler content and coating thickness. Moreover, we also found that thermal conductivity has the influence on the infrared stealth ability to some extent. The infrared stealth ability improved with the increase of thermal conductivity. Different infrared emissivity coatings were made by adjusting the filler content and coating thickness and took thermographs under different surroundings. It showed that the coatings have good camouflage ability under different surroundings.
