Abstract

A test piece was produced using deteriorated pine tree for the conservation treatment of woodblocks cultural heritage, and weight change, color change and penetration diffusion characteristics of the test piece according to the application of Dammar, Wax, Paraloid B-72, Animal glue and H.P.C treatment agent. As a result, it was confirmed that Dammar is the most suitable treatment agent for the strengthening of the material while maintaining the original color of the wood. A test piece was produced using deteriorated porous natural wood, which the damage condition is similar to that of woodblocks cultural heritage and the main tree of woodblocks cultural heritage based on above result, and the application of each Dammar concentration (2%, 5%) and wetting of each Dammar concentration (10%, 15%) were conducted in order to find out the application concentration and treatment method of Dammar, and weight change, penetration diffusion characteristics, etc. were observed. As a result, it was found that the Dammar 2% application was the best as an effective method for the strengthening of the material while maintaining the original color of the wood. Therefore, it is judged that Dammar 2% application is most suitable for the strengthening treatment of woodblocks cultural heritage with severe insect damage and degradation.

본 연구에서는 목판 문화재의 보존처리를 위해 열화된 소나무를 이용하여 시험편을 제작하고 Dammar, Beeswax, Paraloid B-72, 아교, H.P.C 처리제 적용에 따른 시험편의 중량변화와 수축률, 색 변화, 침투확산 특성을 관찰하였다. 그 결과 목재 본래의 색을 유지하며 재질 강화에 효과적인 처리제로 Dammar이 가장 적합한 것으로 확인되었다. 위 결과를 토대로 목판 문화재와 손상 상태가 유사하며 목판 문화재의 주요수종과 유사한 열화된 산공재 수종을 이용하여 시험편을 제작하고 Dammar의 적용농도 및 처리 방법을 알아보고자 Dammar 농도별(2%, 5%) 도포와 Dammar 농도별(10%, 15%) 함침을 진행하였으며 중량변화, 침투확산 특성 등을 관찰하였다. 그 결과 목재 본연의 색을 유지하면서 재질 강화에 효과적인 방법으로 Dammar 2% 도포가 가장 우수한 것으로 나타났다. 따라서, 충해 및 열화가 심한 목판 문화재의 강화처리에는 Dammar 2% 도포가 가장 적합한 것으로 판단된다.
