摘　　要：目的研究灌封材料在南海海洋大气中的环境效应。方法在南海西沙永兴岛开展24个月棚下大气暴露试验,分析其性能劣化规律,评价其环境适应性。开展实验室高温及湿热人工模拟试验,并对比分析自然与人工模拟试验的相互关系。结果参与试验的16种材料有5种材料环境适应性较好,10种环境适应性一般。高温试验后参与试验的材料主要性能指标与棚下的相关性均为中等强度相关或之下,11种材料的介电常数性能、体积电阻性能劣化加速倍数超过2倍以上。湿热试验后有11种材料主要性能指标与棚下的相关性均为中等强度相关或强相关,10种材料表面电阻性能劣化加速倍数超过3倍以上,14种材料体积电阻性能劣化加速倍数超过3倍以上。结论在西沙棚下海洋大气环境中,该批试验的灌封材料环境适应性一般。湿热试验与西沙棚下大气暴露试验相关性较好,湿热试验对性能劣化加速性较好。Objective To study the marine environmental effect of a few encapsulating materials in South China Sea. Methods The exposure test of a few encapsulating materials was carried out under shelter on Yongxing Island of Xisha in South China Sea for 24 months. The environmental effect and the environmental adaptability were analyzed. At the same time, the high temperature test and the humidity-heat test were completed. The correlativity between the environmental test and the artificial simulation test was compared and analyzed. Results There were 5 kinds of materials with better environmental adaptability and 10 kinds of mate- rials with medium environmental adaptability in the tested 16 materials; the correlation between high temperature test and marine atmosphere expose test was medium or lower than medium, and there were 11 kinds of materials, which acceleration factor of di- electric constant and volume resistance were more than 2 times; there were 11 kinds of materials, which correlation between humid- ity-heat test and marine atmosphere expose test was medium or higher than medium, and there were 10 kinds of materials, which acceleration factor of surface resistance were more than 3 times, and there were 14 kinds of materials, which acceleration factor of volume resistance were more than 3 times. Conclusion The environmental adaptability of the tested encapsulating materials was medium under shelter on Xisha of South China Sea. The correlation between humidity-heat test and marine atmosphere expose test were preferable, and the humidity-heat test has better performance degradation acceleration effect.
