Study on Correlation between Marine Environmental Test and Accelerated Tests in Laboratory for Ship Coatings——Coating Systems for Marine Atmosphere

采用光泽-色泽仪、涂膜粉化率测定仪、fdIr,SEM及AfM等现代测试分析手段,对海洋大气区7种常用舰船涂料体系在实际海洋环境暴露试验以及室内人工加速老化及腐蚀试验前后的涂层性能变化进行了对比分析,并结合厦门地区的气象环境谱探索了实验室加速试验与实际海洋大气暴露试验的相关性。Seven ship coating systems were exposed in marine atmospheric environment and accelerated weathering tests in lab.Some modern analyses,such as gloss and color measurement,coat chalk rating,precise thickness meter,FDIR,SEM,AFM were applied to characterize the properties of the coating systems.The results of performance change before and after exposure were compared.The weather environmental spectrum of Xiamen area was also combined for discussion of the correlation between marine environmental exposure tests and accelerated weathering tests in lab
