Abstract

In this study, an advanced epoxy putty which was as a multi-purpose restoration material being used to restore missing parts in the artifact preservation treatment process was developed. For the purpose of addressing the issues including the workability issue resulting from high strength, the drooping issue resulting from long hardening time during work process and the issue of contaminating the surface of artifact resulting from stained material on tools or gloves, a property comparison was conducted with existing materials to examine the properties of restoration materials in the form of epoxy putty currently being frequently used. For the purpose of addressing the issues of existing materials and allowing the developed epoxy putty to have similar properties, two types of hardeners with different properties were selected to conduct property experiments. As for the hardeners, mercaptan type hardener and aliphatic amine type hardeners in the total of two types were selected for the development. The result showed that the two types were both in the form of paste and their hardening time of 5-10 minutes were about 3-10 times shorter than that of existing materials, thereby improving the work convenience. In terms of abrasion rate to increase workability, it was improved by about 3 times to allow effective and convenient use. As for the issue of contaminating the artifact surface during the process, white micro-balloon was added as filler to address the issue to reduce the oil ingredient to develop multi-purpose restoration material with low shrinkage & high workability in coloring, light weight and cutting force.

본 연구에서는 유물의 보존 처리 과정에서 결손 부위의 복원을 위해 적용 가능한 다목적용 복원재료로써 Epoxy Putty를 개발하고자 하였다. 기존에 사용되고 있는 재료의 물성에서 드러난 높은 강도로 인한 가공성의 문제, 작업 과정 중 긴 경화 시간으로 인한 처짐 현상, 도구나 장갑에 묻어 유물의 표면을 오염시키는 등의 문제점을 해결하기 위해, 1차적으로 현재 많이 사용되고 있는 Epoxy Putty 형태의 복원 재료 물성을 파악한 후 이를 비교 대상으로 선택하여 경화제와 충전제의 종류에 따른 Epoxy Putty를 개발하였다. 개발 된 Epoxy Putty는 기존 재료의 문제점 해결 및 유사한 물성을 지니기 위해 성상(性狀)이 다른 2종의 경화제를 선정하여 물성 실험을 실시하였다. 경화제로는 Mercaptan 계열의 경화제와 Aliphatic amine 계통의 경화제 2종을 선택하여 개발하였다. 연구 결과 2종 모두 Paste 형태로 경화 시간은 5~10분 내외로 기존 재료에 비해 약 3~10배 정도 짧아 작업의 편리성을 높였으며, 가공성을 높이기 위한 마모율은 약 3배 정도 향상시켜 쉽게 사용할 수 있도록 하였으며, 작업 중 발생하는 표면 오염 등의 단점을 보완하기 위해 충전제로 백색의 Micro-balloon을 첨가하여 사용 중 손에 묻어 나오는 끈적거리는 현상을 줄여주었을 뿐만 아니라 Coloring, 경량성, 절삭력 등이 높은 저수축 및 가공성이 우수한 다목적 복원 재료를 개발하였다.
