摘　　要：为明确典型防护涂层体系在南海地区服役性能,实现实验室人工加速试验对涂层在自然环境下老化过程的良好模拟,收集南海特征区域海洋大气环境数据,设计人工紫外老化试验,并对比人工紫外老化及南海自然暴露过程中涂层表面形貌和防护性能的变化。结果表明,人工紫外老化试验可较好反应防护涂层体系在南海地区的使用情况,与南海自然暴露试验相关性良好,基于涂层附着力、色差和失光率测试的加速因子分别为8.6,8.8和11.6。In order to clarify the service performance of typical protective coating systems in the South China Sea and achieve a good simulation of the artificial aging process of the laboratory to natural environment,atmospheric and environmental data in the characteristic area of the South China Sea were collected,and an artificial accelerated aging test was designed.On this basis,contrastive analysis of the coating surface morphologies and protective performances during artificial aging and natural exposure in the South China Sea were carried out.The result shows that the artificial UV aging test can well reflect the service of the protective coating system in the South China Sea,and that it has a good correlation with the natural exposure test in the South China Sea.The acceleration factors based on the coating adhesion,color and gloss test are 8.6,8.8 and 11.6,respectively.
