Development of Aging Equipment and Testing Method for UV Effected Degradation Characteristics of Silicone Rubber

자외선 열화에 의한 실리콘고무의 열화 특성 연구를 위한 열화장치 및 시험방법의 개발

In this paper, the testing equipment for evaluating aging characteristics of outdoor silicone rubber insulator resulting from the environmental aging effect with regards to sunlight(UV) was developed. Influence of sunlight effect aging is seriously increase due to destruction of ozone layer which is occurred by consumption of fossil fuel. For this purpose, silicone rubber was aged under the artificial sunlight by exposure of xenon lamp radiation in the accelerating aging chamber and various test and analysis were performed such as breakdown strength, contact angle. And FT-IR analysis has been followed.
