| Abstract: |
| 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. |
