摘要：

In order to study the corona aging characteristics of silicone rubber materials with different proportions under haze conditions, three types of silicone rubber materials with different proportions were selected, and the aging characteristics were tested by the static contact angle, scanning electron microscope, and Fourier transform infrared spectrum. The results show that the corona aging characteristics of the three types of silicone rubber materials with different ratios under haze conditions are quite different. Among them, the corona aging characteristics of the A-type materials with low silica gel content and high aluminum hydroxide content is relatively excellent, which are manifested in better surface morphology and fewer attachments. The hydrophilic groups can migrate to the interior of the material at a faster speed, so the recovery rate is the fastest, but the hydrophobicity loss of such materials is relatively serious. At the same time, the characteristic peak areas of the Si—O—Si group and Si—CH3 group in such materials after aging are relatively large, the main chain and side chain are more complete, and the chemical structure damage is the smallest. © 2022 Hunan University.
