摘　　要：氧化亚铜(Cu2O)作为在目前海洋防污涂料广泛使用的防污剂,研究其渗出速率和在海洋环境中的降解行为具有重要的意义。介绍了ISO15181铜离子渗出速率测试方法,并研究了不同配方的自抛光型防污涂料的铜离子渗出速率,最后研究了氧化亚铜在海洋环境中的降解行为。结果表明:铜离子渗出速率可通过涂料配方进行调整,氧化亚铜在海洋环境中的最终降解产物是碱式碳酸铜。Cuprous oxide is the main biocide used in marine antifouling paints, it＇s very important to in- vestigate the leaching rate and degradation behavior of cuprous oxide. The ISO 15181 test method of copper- ion release rate was described in this paper, and the copper - ion release rate in different self - polishing an- tifouling paints formulations was discussed, and the degradation behavior of cuprous oxide in the marine en- vironment was investigated. The results showed that the release rate of copper - ion could be adjusted by paint formula, the final degradation product of cuprous oxide in the marine environment was basic cupric carbonate.
