FIRE-RETARDANT WOOD AND WOOD COMPOSITES, AND COMPOSITIONS USEFUL FOR MAKING SAME
An amino-functionalized polyglycerol phosphate flame retardant can be synthesized through polycondensation of glycerol and phosphoric acid, followed by crosslinking with one or more amino functionalized compounds such as ethylene diamine or polyethyleneimine. The formulation is optionally enhanced with halloysite nanotubes or other clay minerals, which not only act as direct flame retardants but can also serve as carriers for flame-retardant compounds, aiding in controlling the migration of the flame retardants, and enhancing their long-term effectiveness. The flame-retardant is preferably combined with a water-resistant glue, allowing its application as a durable coating on wood substrates. The coating provides fire, water, and biological resistance.
