| 目的 研究涂层在自然环境试验和实验室模拟环境试验下性能的变化情况，通过再现涂层在自然环境下的环境效应和损伤过程，进而验证该模拟热带海洋大气环境试验方法的合理性。方法 根据涂层在舰船、舰载机等装备上热带海洋大气实际服役环境的分析，通过对热带海洋大气环境温度、湿度、盐雾、太阳辐射环境因素的组合，综合设计模拟热带海洋大气环境试验方法的试验流程，开展3种涂层在海南万宁为期1 a和实验室总周期为7循环的对比试验。结果 3种涂层在自然环境试验和实验室模拟环境试验后，随着试验时间的延长，其性能变化趋势相似，失光率和色差增大，附着力明显降低，交流阻抗值减小。红外光谱分析显示，老化机理均未出现明显变化，以光泽和色差为基准的平均秩相关系数为0.87，为极强相关。结论 本模拟热带海洋大气环境试验方法设计合理，具有良好的模拟性。 |

| The work aims to study the performance changes of coatings in natural and simulated tropical marine atmospheric environments, to verify the rationality of the method for simulating marine atmospheric environment by reproducing the environmental effects and damage processes of coatings in natural environments. Based on the analysis of the coating on ships, carrier based aircraft, and other equipment in the tropical ocean atmosphere, and in combination with environmental factors such as temperature, humidity, salt mist, and solar radiation in the tropical marine atmosphere, a comprehensive experimental process was designed to simulate the tropical ocean atmosphere environment in the laboratory. A comparative test of three coatings in Wanning, Hainan for a period of one year and a total laboratory cycle of seven cycles was conducted. According to the test of three coatings in the natural environment and the simulated environment in laboratory, the performance changes of coatings showed a similar trend. The loss of light and color difference increased, the adhesion significantly decreased, and the AC impedance value decreased. The infrared spectroscopy analysis showed no significant change in the aging mechanism. The average rank correlation coefficient based on gloss and color difference was 0.87, which is highly correlated. The experimental method for simulating tropical marine atmospheric environment is reasonable in design and has good simulation performance. |
