Zusammenfassung: | The present invention relates to a solvent-free low-viscosity epoxy-based sealant composition for improving insulation properties of a ceramic thermal spray coating layer and a ceramic coating part using the same. The solvent-free low-viscosity epoxy-based sealant composition includes: 30 to 50 wt% of an epoxy resin; 45 to 65 wt% of a curing agent; 4.5 to 11 wt% of a reactive diluent; and 0.1 to 2 wt% of a curing catalyst, improves permeability by lowering the viscosity and contact angle, and can penetrate deep into pores occurring in the existing ceramic spray coating, so that it is possible to provide a highly reliable ceramic thermal spray product by improving insulation resistance characteristics of ceramic thermal sprayed products and reducing the defect caused by arcing.
본 발명은 세라믹 용사 코팅층의 절연 특성 향상을 위한 무용제 저점도 에폭시계 실란트 조성물 및 이를 이용한 세라믹 코팅 부품에 관한 것으로, 에폭시 수지 30~50중량%, 경화제 45~65중량%, 반응희석제 4.5~11중량% 및 경화촉매 0.1~2중량%를 포함하는 것을 기술적 특징으로 하며, 점도 및 접촉각을 낮춰 침투성을 향상시켰으며, 기존 세라믹 용사 코팅에서 발생하는 기공의 깊은 곳까지 침투할 수 있으므로, 세라믹 용사 제품들의 절연저항 특성을 향상시켜 아킹에 의한 불량을 개선하여 신뢰성이 높은 세라믹 용사 제품을 제공할 수 있는 장점이 있다. |
