초록

본 연구는 다양한 천연물계 항균물질로부터 추출된 추출액(extract)들의 자체 항곰팡이 성능을 평가하고, 이를 적용한 항균모르타르의 항곰팡이 성능과 그 지속성능, 그리고 항균성능 등에 대해 종합적으로 고찰함으로써 효율적인 건축물 내 항균대책 및 친환경 항균 건자재(모르타르 포함) 개발을 위한 기초적 자료를 제공하고자 수행하였다. 시험결과, 마조람 추출액 및 이를 적용한 항균모르타르의 항곰팡이 성능은 현재 널리 사용되고 있는 유기계 화학 항곰팡이제 및 이를 적용한 모르타르와 동등수준의 높은 항곰팡이 성능을 나타내었다. 특히 마조람 추출액 5% 혼입 모르타르는 장기 항곰팡이 성능뿐 아니라 대장균, 녹농균 및 황색포도상구균에 대한 항균성능에서도 뛰어나 그 활용가능성이 크게 기대되었으며, 향후 이에 대한 보다 상세한 검토가 요구된다.

This study discusses the long-term antifungal effect and antifungal performance of Hwangtoh mortars with various natural antifungal substances on five types of mold: Chaetomium globosum, Aspergillus niger, Aureobasidium pullulans, Gliocladium virens, and Penicillium pinophilum, which can be easily detected in the indoors and outdoors of buildings in damp environments. The antifungal performances of various natural antifungal substances extracted from Marjoram, Phytoncide, Thyme, Ginkgo leaves, and Chitosan (oligosaccharide) were investigated on the five types of mold, as a basic experiment. Using the natural antifungal substances selected for the basic experiment, antifungal mortars were made, and their antifungal performance and long-term antifungal effects were also investigated. The results clearly showed that the marjoram extract and their associated mortars had excellent antifungal performance. Also, their long-term antifungal effects were outstanding and at an equivalent level to those of the mortars with organic chemical antifungal agents. The optimum addition rate of the marjoram extract in the mortar was 5% by mass of binder. It was also shown that the phytoncide extract in the mortar needed an addition rate of more than 10% according to the mass of binder, considering the long-term antifungal effect and the antifungal performance.
