Fire-retardant properties of wood particleboards treated with boric acid

Feuerhemmende Eigenschaften von mit Borsäure imprägnierten Spanplatten

Abstract

The fire-retardant performance of wood particleboards treated with three percentages (8, 12, and 16%) of boric acid was determined. Particles were treated during wood particles blending with adhesive. Fire-retardant properties were measured according to ASTM D3806 Standard Test Method of Small-Scale Evaluation of Fire-Retardant Paints, (2-Foot Tunnel Method). Particleboards treated with 16% boric acid showed the best fire-retardant properties, particularly in terms of weight loss, flame spread speed and afterflame time. The use of white birch inner bark particles as dispersant also lowered particleboard weight loss during fire testing. The use of boric acid not only decreased the flame spread speed but also greatly improved the internal bond and thickness swelling of manufactured particleboards over controls.

Zusammenfassung

Untersucht wurde das feuerhemmende Verhalten von Spanplatten, die mit 8, 12 und 16 % Borsäure imprägniert wurden. Die Imprägnierung der Späne erfolgte im Rahmen der Klebstoffzugabe. Die feuerhemmenden Eigenschaften wurden gemäß ASTM D3806 im Kleinprüfstand bestimmt (2-Fuß-Tunnelmethode zur Prüfung feuerhemmender Anstriche). Die mit 16 % Borsäure behandelten Spanplatten zeigten die besten feuerhemmenden Eigenschaften, insbesondere hinsichtlich Masseverlust, Flammenausbreitungsgeschwindigkeit und Nachbrennzeit. Die Verwendung von Bastpartikeln der Papierbirke als Dispersionsmittel führte ebenfalls zu einer Reduzierung des Masseverlustes der Spanplatten beim Brandversuch. Die Verwendung von Borsäure hatte nicht nur einen Rückgang der Flammenausbreitungsgeschwindigkeit zur Folge, sondern führte auch zu einer Verbesserung der Querzugfestigkeit und der Dickenquellung der hergestellten Spanplatten im Vergleich zu den Kontrollplatten.
