Abstract :
ATH is added to the silicone rubber(SIR) for the improvement of its resistance against surface discharge. Hydrophobicity recovery properties and arc resistance of SIR could be different by the content, surface treatment state and particle size of ATH. For material study, ATH with different particle sizes was added during compounding. SIR was deteriorated by a corona treatment. Hydrophobicity recovery rate after corona treatment and arc resistance of silicone samples were investigated. Hydrophobicity recovery rate of SIR were evaluated by the measurement of contact angle. Arc resistance was evaluated by measuring weight loss after arc resistance test. Surface state of SIR after corona treatment was investigated by a scanning electron microscope. It was observed that the hydrophobicity recovery rate and arc resistance were different from particle size of ATH.
