Abstract

Furfurylated wood exhibits excellent dimensional stability and corrosion resistance, making it a promising material for constructing buildings, but it is highly flammable. Herein, flame-retardant furfurylated poplar wood was produced via a two-step process utilizing boric acid (BA) and ammonium dihydrogen phosphate (ADP) as flame-retardant components, and biomass-derived furfuryl alcohol (FA) as a modifier. The acidity of BA and ADP allowed them to catalyze the polymerization of FA, which formed a cross-linked network that immobilized BA and ADP inside the wood. The addition of BA/ADP substantially delayed the time to ignition from 10 to 385 s and reduced the total heat release and total smoke release by 58.75% and 77.31%, respectively. Analysis of the pyrolysis process showed that the decomposition products of BA and ADP protected the underlying furfurylated wood and diluted combustible gases. This method significantly improved the fire retardancy and smokeless properties of furfurylated wood, providing promising prospects for its application as an engineering material.
