Abstract

This paper reports on the results of weathering test, tracking test and salt-fog test of various kinds of cycloaliphatic epoxy systems. UV irradiation dramatically induced the loss of surface hydrophobicity due to the chain scission attack at the surface under UV irradiation. It could be seen that samples containing an UV absorbent/antioxidant and a silicone oil additive have a good performance in weathering test, while ATH(alumina tri-hydrate) filled ones have high resistance against tracking failure than others. Under salt fog chamber test, specimens mixed with silicone oil are able to suppress leakage current development. It was thought that silicone oil mixed into cycloaliphatic epoxy system could lead to lower the surface energy and to retain hydrophobic properties for a long time, which are desirable for outdoor use.

본 논문은 옥외용 절연재료로 사용되는 싸이클로알리파틱계 에폭시 재료의 여러 가지 컴파운드 비에 따른 내후성, 내트래킹 및 염무시험 결과를 나타낸 것이다. 시험 결과, 내후성 시험 동안의 자외선 조사로 인하여 표면에 결합쇄의 절단으로 표면 발수성 손실이 나타났다. 자외선 차단제와 산화안정제 및 실리콘 오일 첨가제가 포함된 시료에서 내후성이 우수한 것으로 나타났으며, 충전재 중 ATH가 포함된 시료에서 내트래킹성의 향상을 확인하였다. 염무시험에서는, 에폭시 수지 내에 실리콘 오일 성분이 포함된 시료가 누설전류 억제 효과를 나타내었다. 본 논문을 통하여 옥외용 절연재료로 사용되는 싸이클로알리파틱 절연재료의 옥외성능에 실리콘 오일성분이 표면에너지를 낮추고 발수성을 오랜 기간 유지할 수 있어 옥외 성능에 바람직함을 알 수 있었다.
