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

Abstract

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.
