Abstract
Due to the pressing issue of global warming, eco-friendly buildings have gained significant attention, and among them, wooden buildings are particularly notable for their eco-friendliness. Wood offers several advantages, including sound insulation and carbon dioxide reduction. However, wood is vulnerable to corrosion and pests, which is why it is often treated with a type of paint known as oil stain. While oil stain provides insect-repellent, antibacterial, and water-resistant properties, it lacks fire resistance, leading to real-life accidents. This study addresses this issue by incorporating a flame retardant into oil stain and applying it to three different types of wood. The research focuses on analyzing the flame retardant's performance and the characteristics of the treated wood, examining flame retardant effectiveness, moisture content, and wood absorption. The findings indicate that as the flame retardant content increases, so does its fire-resistant performance. Among the wood types, acacia plywood exhibited the highest performance, while MDF plywood demonstrated the lowest. Interestingly, variations in moisture content and absorption were not significantly affected by the increased addition of the flame retardant.
