목재밀도와 방염처리방법에 따른 방염성능분석 연구

Analysis of Flame-Retardant Performance Based on Wood Density and Flame-Retardant Treatment Method

이 연구를 위해 실생활 및 건축 인테리어 재료로 많이 사용되는 목재 중 밀도가 다른 4종류(가문비나무, 저/중/고밀도 MDF)를 선정하였다. 이들 각각에 대해 방염도료(수성과 유성) 및 방염액을 3가지 방염처리방법(롤러법, 붓칠법, 분무법)으로 2~5회 도포 및 분무하여 방염성능을 시험하였다. 시험결과를 토대로 밀도가 다른 4종류의 목재시료에 대해 방염도료(수성/유성) 및 방염액, 방염처리방법, 방염도포횟수별 방염성능과 착화시간을 비교 분석하였으며, 이러한 연구 결과는 목재의 밀도와 방염처리방법에 따른 방염성능 변화에 대한 실증적 자료로 활용될 수 있을 것이다.

For this study, four types of wood with different densities (spruce and low-, medium-, and high-density fiberboards) were selected from wood widely used as materials in real life, particularly in architectural interiors. For each wood type, flame-retardant paints (water- and oil-based) and flame-retardant liquids were applied two to five times using three flame-retardant treatment methods (roller, brush, and spray) to test the flame-retardant performance. For the four types of wood specimens with different densities, their flame-retardant performances and ignition times were compared and analyzed according to the applied flame-retardant paint (water- and oil-based) and liquid, treatment method, and frequency at which a specific paint was applied. These results can be used as empirical data on changes in flame-retardant performance based on density of wood and flame-retardant treatment method.
