싸이클로알리파틱 에폭시 절연재료의 옥외 성능에 미치는 충전재 및 첨가물의 영향

초록

This paper reports on the evaluation of weathering resistance, tracking test and salt-fog of various kinds of cycloaliphatic epoxy systems. It was found that UV irradiation induced the loss of hydrophobic level due to the chain scission attack at the surface. It could be seen that samples containing an UV absorbent/antioxidant and a silicone oil additive have a good performance in weathering ageing, whereas ATH filled ones have high resistance against tracking failure than others. Under salt-fog test,specimens 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 performances.
