摘要
以环氧改性有机硅为基料、铝粉为填料,制备了低红外发射率涂层。研究固化温度对涂层综合性能(力学特性和耐腐蚀性能)的影响,并对其影响机理进行分析。结果表明,当固化温度为180℃,制得的涂层能在保持低红外发射率的同时具有最佳的综合性能,涂层中填料与树脂基体形成的界面结合良好,呈致密膜状,基本实现了红外隐身涂层低发射率与工程应用性能的兼容。
Low infrared emissivity coatings were prepared using epoxy-modified silicone and Al powder as adhesive and pigment, respectively. The influence and mechanism of curing temperature on mechanical and anti-corrosion properties of low infrared emissivity coatings were researched. The results indicate that the comprehensive performances reach the optimum when the coatings are cured at 180 ℃, the interface formed by adhesive and pigment is tight, and the coatings are compact. The coatings keep the low infrared emissivity, which can realize the compatibility of low infrared emissivity and engineering applications.
