천연 원료 종류에 따른 탄산칼슘계 백색 안료를 백악과 호분으로 구분하여 제조하고 재료학적 특성을 분석하였으며 내후성, 항진균, 방염성 평가를 실시하여 성능을 비교하였다. 백악 안료는 calcite, dolomite, 호분 안료는 calcite, aragonite가 주구성 물질이며 백악 안료는 광물 조성에 의한 Mg, 호분 안료는 단백질에 기인한 P, S 성분이 특정인자로 확인된다. 안료의 입자 형태는 백악 안료의 경우 광물 특유의 결정 구조를 보이지만 호분 안료는 원료에 따라 판상 또는 주상 조직으로 구분되고 응집된 상태로 비표면적이 큰 편이다. 흡유량은 석회암 및 백운 석이 원료인 백악 안료는 유사한 반면 호분 안료는 원료에 따른 차이를 보이는데 벚굴 > 꼬막 > 대합 순으로 흡유량이 높았다. 색도분석 결과, 백악과 호분 안료 모두 L* 값이 90이상이고 은폐력도 90이상으로 백색도 및 채색 작업성이 양호하였다. 촉진내후성시험 결과, 최종 색차값 (ΔE)이 2.02 미만으로 육안으로 인지하기 어려운 수준이며 백악 안료에 비해 호분 안료가 색 및 도막 안정성이 우수하였다. 항진균 시험 결과, 탄산칼슘계 백색 안료 모두 부후균에 대한 예방 효과가 높았으며, 이 중에서도 대합과 꼬막을 원료로 한 호분 안료의 방부성이 우수하였 다. 또한 대합과 꼬막이 원료인 호분 안료는 방염성을 지니는 것으로 나타나 유기질 문화유산 에 적용 시 보존성을 높이는데 기여할 것으로 판단된다.
Abstract
Calcium carbonate white pigments were manufactured by classifying them into Baekak(chalk) and Hobun(Shell) according to the type of natural raw material, and their material characteristics were analyzed. Their performances were compared by evaluating their weather resistance, antifungal activity, and flame retardancy. The main components of Baekak pigments are calcite and dolomite, and those of Hobun pigments are calcite and aragonite. Depending on the raw material, the specific factors identified are Mg from the mineral composition of Baekak pigments, and P and S from the protein composition of Hobun pigments. The particle shape of the pigment shows a crystal structure unique to minerals in the case of Baekak pigments, but the Hobun pigments are classified into plate-shaped or columnar structures depending on the raw material and are in an aggregated state with a large specific surface area. While the absorption amount of Baekak pigments made from limestone and dolomite is similar, that of Hobun pigments shows differences depending on the raw material, with the absorption amount being high in the order of oyster > cockle > clam. As a result of the color analysis, both the Baekak and the Hobun pigments had L* values of over 90 and opacity of over 90, indicating good whiteness and painting workability. As a result of the accelerated weathering test, the final color difference value(ΔE) was less than 2.02, which was difficult to recognize with the naked eye, and the Hobun pigment showed superior color and film stability compared to the Baekak pigment. As a result of the antifungal test, all calcium carbonate-based white pigments showed high preventive effects against decay fungi, and among them, the pigment made from clams and cockles showed excellent antiseptic properties. In addition, the pigment made from clams and cockles has been shown to have flame retardant properties, and it is expected that it will contribute to enhancing the preservation of organic cultural heritage when applied to it.
