| 目的 考察机载电子设备常用灌封材料在西沙环境下的耐老化性能。方法 开展西沙海洋环境下4种灌封材料的棚下暴露实验，暴晒实验时间为3年，分别通过测试表面电阻、体积电阻、介电常数、损耗角正切等手段研究其老化特点。结果 267有机硅、DC160有机硅两类样品外观未出现明显变化，且介电常数、损耗角正切、表面电阻、体积电阻均变化较小，112FR环氧树脂、8836聚氨酯两类样品出现变色、产生针孔起泡等现象，介电常数、损耗角正切、表面电阻和体积电阻均变化幅度较大。结论 在机载电子设备选用绝缘灌封材料时，可优先选用267有机硅、DC160有机硅这两类灌封材料，112FR环氧树脂和8836聚氨酯谨慎选用。 |

| Objective To investigate the aging resistance of commonly used potting materials for airborne electronic equipment in Xisha environment. Methods The experiment was carried out on four kinds of potting materials by exposing them for 3 years in the Xisha marine environment. Their aging characteristics were studied by testing the surface resistance, the volume resistance, the dielectric constant, the loss tangent, etc. Results Samples of 267 silicone, DC160 silicone did not show significant changes in the appearance. Their dielectric constant, loss tangent, surface resistance, volume resistance changed slightly. Samples of 112FR epoxy resin and 8836 polyurethane appeared discoloration, pinhole foaming and other phenomena. Their dielectric constant, loss tangent, surface resistance and volume resistance changed greatly. Conclusion In selection of insulating potting material for airborne electronic equipment, 267 silicone, DC160 silicone might be given preference; 112FR epoxy resin and 8836 polyurethane should be selected carefully. |
