본 연구는 전통 옻칠 기법을 이용하여 금속표면을 코팅하고, 물성을 평가하여 옻칠의 금속코팅 적용성 여부를 알아보고자 했다. 이를 위해 SS275 금속 시편(60*60 mm)과 원주 생칠을 이용하였다. 또한 칠 횟수(1, 2, 3)와 가열온도(120℃, 150℃)를 변이조건으로 설정하여 총 6개의 시편을 제작하였다. 분석은 색도측정, 접촉각 및 표면에너지 측정, 내약품성 시험, Cross-cut 시험을 이용하였다. 분석결과 부식성이 개선되고 금속표면에 대한 옻칠의 밀착력이 우수함을 확인하였다. 접촉각 및 표면에너지는 큰 변화를 보이지 않았다. 또한 색도 역시 큰 차이는 보이지 않았다. 본 연구를 통해 금속 표면에 옻칠이 진행되면 방수성 및 방식성이 좋아짐을 확인하였으며, 적정한 옻칠 횟수와 가열온도를 확인하였다. 차후 경도와 마모율과 같은 물리적인 특성 연구와 일정한 두께로 옻을 칠하는 방안을 연구하여 금속의 적용 가능성을 확인하고자 한다.

This study uses traditional lacquer techniques to coat the metal surface and evaluates its physical properties to check the applicability of the lacquer coating. For this purpose, a total of six specimens were produced by setting the variation conditions for the number of times (1, 2, 3) and the heating temperature (120℃, 150℃) using SS275 metal(60*60 mm) and 'Wonju lacquer'. For analysis, chromaticity measurements, contact angle/surface energy measurements, Chemical Resistance, and cross-cut tests were used. The analysis showed that the corrosivity was improved and the adhesion of lacquer to the metal surface was excellent. There was no significant change in contact angle/surface energy. Also, there was no significant difference in color. Through this study, it was confirmed that lacquer on metal surfaces improves waterproofing and has a anticorrosion effect. We could also check the proper number of lacquer and heating temperature. Additional physical characteristics such as hardness and wear rate should be studied. It is also necessary to study how lacquer can be painted with a certain thickness.
