摘要
从填料添加量、粘合剂的选用、填料和粘合剂的优化组合三个方面对红外隐身涂料在8～14μm波段的红外发射率进行研究。研究表明:填料的添加量与涂料发射率有线性和"U"型曲线两种典型关系;当以物理性能良好的聚氨酯为粘合剂时,涂料发射率较高,以红外透明性能较好的三元乙丙橡胶为粘合剂时,涂料发射率可与填料发射率相近;当三元乙丙橡胶与Cu粉优化组合形成涂料时,涂层发射率最低可达0.2。初步分析涂层低发射率的机理,并对其工程化应用展开初探。
Infrared emissivity of camouflage coating in 8-14μm was studied frmn three aspects, ie, the content of pigment, different adhesives, the optimization combination of pigment and adhesives. There were two typical relationships of ＂U＂ shaped curve and linear between pigment content and coating emissivity. The infrared emissivity was high when polyurethane resin （PU） with good physical properties was used as the adhesive. However, when choosing EPDM rubber with good infrared transparent performance as coating adhesive, the results were good. After adding copper powder in EPDM rubber, the infrared emissivity of coating declined, the minimum reached 0.2. The preliminary mechanism and engineering application of the low emissivity coating were also studied.
