초록

손상된 석조문화재 보존을 위한 다양한 강화제가 개발되고 있다. 강화제의 종류에는 에폭시계, 이크릴계, 이소시아네이트계, 알콕시실란계 등이 있다. 본 연구에 사용된 강화제는 1T1G_5 wt 0.08 %로 T (TEOS: Tetraethyl Orthosilicate)와 G (GPTMS: 3-Glycidoxy propyl trimethoxy silane)로 알콕시실란계이다. 강화제 처리 결과 처리 전 쇼어경도값이 낮은 높아지며, 색도 변화는 강화제 처리 후 초기에는 약간 어두워지지만 시간이 지남에 따라 원래의 밝기로 환원된다. 초음파 속도 변화는 강화제 처리 후 초기에는 증가하지만 시간이 지남에 따라 약간 감소하여 일정하게 유지된다. 초음파 속도 증가에 대한 효율은 풍화가 많이 진행되어 초음파 속도가 느린 암석일수록 강화효율이 높다.

Consolidants were extended use for conservation of weathered stone heritage. Epoxy, acryl, isocyanate, and alkoxysilane consolidants are most commonly used products. Consolidant of 1T1G_5 wt 0.08 % that consists of T (TEOS: Tetraethyl Orthosilicate) and G (GPTMS: 3-Glycidoxy propyl trimethoxy silane) were used this study. A shore hardness values show increasing after treated with consolidant in granite. Surface brightness after treated with consolidant are changing slightly dark but turns the original color over time. Ultra-sonic velocity is increased after treated with consolidant but slightly reduced over time to remain constant. It has the advantage of being effective after treated with consolidant in granite and efficiency of consolidation increase with slow velocity before treated with consolidant.
