要約(日本語): The surface degradation of silicone rubber used as outdoor insulator under accelerated uv radiation was investigated. The contact angle, electrical resistivity and various analytic tools such as XPS, DSC and FTIR, were used to analyze phenomena of surface degradation due to an exposure to uv and corona discharge.
UV treated specimens showed a slower decrease of surface hydrophobicity and contents of low molecular weight, which play a role to recovery of surface hydrophobicity. Based on the results of GPC, DSC and FTIR, it was found that uv radiation on silicone rubber leads to oxidize surface layer through the crosslinking oxidative reactions. This was also confirmed by the solvent extraction of low molecular weight and XPS result. Therefore, we could derive the specific surface states of the silicone rubber treated by accelerated artificial aging factors and the degradation process.
