초록

목조문화재의 대부분은 외부 환경에 그대로 노출되어 있어 위치와 크기에 의해 보존에 관련하여 많은 어려움을 가지고 있다. 그중 흰개미나 곰팡이에 의해 발생하는 생물학적 피해는 큰 비용과 시간을 소모하게 한다. 생물학적 피해를 예방하기 위해 목재 보존제를 처리하는 방식을 선택하여 사용한다. 목재 보존제를 선별하여 최악의 환경조건인 온도는 60±3℃, 습도는 55±5%, 광량은 0.35 W/m2로 열화 처리를 하여 화학적 변화를 분석하였다. 열화 과정을 통해 색차변화에서는 Control 군에 비하여 목재 보존제 처리에서 그 변화량이 감소하는 것을 확인하였다. 목재 보존제의 열화 과정에서 함유된 유효성분 함량을 측정한 결과에서도 비교 대상인 Wood Keeper A에 비해 Gori22와 Bondex Preserve III가 유효성분 함량이 높은 것을 확인하였다. 실험을 통해 목재 보존제가 열화 과정에서 목재 시편의 변화에 영향을 주는 정도와 유효성분의 함량을 측정하여 유효 기간 및 처리 기간을 예측할 수 있다. 추후 다양한 목재 보존제를 갖추어 선택적으로 환경이나 지형 및 기간에 맞추어 목재 보존제를 선정하는 데 주요 평가 요인이 될 가능성을 제시하였다.

Wooden cultural heritage are exposed to the external environment as they and there are many difficulties in conservation due to their location and size. Among them, biological damage caused by termites or mold consumes a lot of money and time. Select and use wood preservatives to prevent biological damage: Wood preservatives were selected and the worst environmental conditions, temperature 60±3℃, humidity 55±5%, and light intensity of 0.35 W/m2, were subjected to aging treatment to analyze chemical changes. Through the deterioration process, it was confirmed that the change in color difference decreased in the wood preservative treatment compared to the Control group. As a result of measuring the content of the active ingredient contained in the deterioration process of the wood preservative, it was confirmed that the active ingredient content of Gori22 and Bondex Preserve III was higher than that of the comparative Wood Keeper A. Through experiments, the shelf life and treatment period can be predicted by measuring the extent to which wood preservatives affect the change of wood specimens during the deterioration process and the content of active ingredients. In conclusion, various wood preservatives were prepared, and the possibility of selectively selecting wood preservatives according to the environment, topography and period was presented as a major evaluation factor.
