Abstract

Recently, perforated plywood has become widely used as an indoor sound absorber. Flame retardant treatment is essential for utilization of wood materials as indoor building materials. Among the various flame retardant treatment methods, we focused on pressure impregnation of water-soluble phosphate flame retardant (WPFR) on commercial Hinoki (Chamaecyparis obtusa) plywood. Perforation rates were 0.06, 0.1, 0.3, and 1.7%, and impregnation times were 30, 60, and 90 min. Then, we evaluated the impregnation effect according to the plywood perforation frequency and impregnation time using Pearson's coefficient correlation analysis and multi-linear regression analysis. The higher were the perforation frequency and impregnation time, the greater was the impregnation effect.
