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。

Abstract: Cuprous oxide is the main biocide used in marine antifouling paints, it's very important to investigate the leaching rate and degradation behavior of cuprous oxide. The IS0 15181 test method of copperion release rate was described in this paper, and the copper-ion release rate in different self-polishing antifouling paints formulations was discussed, and the degradation behavior of cuprous oxide in the marine environment 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.

Key words: cuprous oxide, release rate, degradation behavior
