Effects of Particle Size of $Al(OH)_3$ on the Electrical Properties of Silicone Rubber

$Al(OH)_3$의 입자크기에 따른 실리콘 고무의 전기적 특성 연구

$Al(OH)_3$ is added to the silicone rubber for improvement of its resistance against surface discharge. In this paper, four kinds of $Al(OH)_3$ were added to the SIR during compounding. SIR was deteriorated by a corona treatment. Hydrophobicity recovery rate after corona treatment and arc resistance of SIR were investigated. Hydrophobicity recovery rate of SIR was evaluated by the measurement of contact angle. Arc resistance was evaluated by measuring weight loss of SIR after arc resistance test.
