| 目的 研究267有机硅、DC160有机硅、112FR环氧树脂、8836聚氨酯4种灌封材料西沙海洋大气环境与实验室环境试验的相关性。方法 在西沙海域环境开展267有机硅等4种灌封材料的棚下暴露试验，暴晒试验时间为3年。同时在实验室开展湿热试验，分别通过测试表面电阻、体积电阻、介电常数、损耗角正切研究两种试验环境的相关性。结果 将以体积电阻、表面电阻、介电强度、损耗角正切为基准相关性评价结果进行平均，得出灌封材料实验室加速试验和自然暴露试验的秩相关系数为0.66，为强相关。4种灌封材料的加速系数分别是6.6，4.9，4.5，8.3。结论 建立了灌封材料在西沙海洋环境试验和实验室湿热环境试验的相关性，可为后续西沙环境试验的加速处理提供依据。 |

| Objective To study on the correlation between potting materials such as 267 silicone, DC160 silicone, 112FR epoxy resin and 8836 polyurethanein Xisha ocean atmospheric environment and laboratory environmental test. Methods Exposure test under shed was carried for 267 silicone, etc four potting materials in Xisha sea environment for 3 years, while damp heat test was carried out in the laboratory. The relevance of the two test environments was studied through testing surface resistance, volume resistance, dielectric constant, loss tangenty. Results The rank correlation coefficient between the laboratory accelerated test and the natural exposure test was 0.66, which was the average correlation between the volume resistance, the surface resistance, the dielectric strength and the loss tangent. They were strongly correlated. The accelerating coefficients of the four potting materials were 6.6, 4.9, 4.5 and 8.3 respectively. Conclusion The correlation between the potting materials and the hot and humid environment tests in the Xisha environment is established by the rank correlation coefficient method, which can provide basis for accelerated and simplified treatment of subsequent Xisha environmental test. |
