摘要
通过傅里叶红外变换光谱以及光泽、色差、附着力等测试手段,对冷轧钢板表面环氧底涂以及环氧底漆+聚氨酯面漆涂层体系经过紫外老化(UV)、中性盐雾试验(NSS)或紫外老化-中性盐雾腐蚀循环试验(UV–NSS)后的性能进行了对比研究。相比传统的单一NSS和UV试验,UV–NSS试验提供了一个动态多因素相互作用的试验体系,更接近复杂的服役环境,反映出涂层实际的耐腐蚀效果。
The performances of an epoxy primer and an epoxy primer + polyurethane topcoat system after ultraviolet aging(UV) test, neutral salt spray(NSS) test, and cyclic ultraviolet aging + neutral salt spray(UV–NSS) test were analyzed compactively by Fourier-transformer infrared spectroscopy and testing their glossiness, color difference, and adhesion strength. As compared with the traditional NSS and UV tests, UV–NSS test provides a dynamic multi-factor interaction system, which is more similar to the complicated service environments, and more effectively reflects the actual anticorrosion performance of coatings.
