Resumen:
The aim of this paper was to know the fire performance of wood panels (Araucaria angustifolia) impregnated in pressure vessel with post-cured alkaline silicates (water glasses). Several commercial silicates based on sodium ions and potassium ions with 3.0/1.0 and 3.5/1.0 silica/alkali molar ratios were selected. Various treatments for curing were applied for polymerization, reaching metallic silicic polymers of high water insolubility.
Experimental panels were tested in a Limiting Oxygen Chamber (Limiting Oxygen Index) and in a Two-Foot Tunnel (Flame-spread index and Panel consumption). Test results displayed a high fire retardant efficiency of some post-cured alkaline silicates.
Keywords: wood, fire-retardant impregnant, soluble alkaline silicates, Limiting Oxygen Chamber, Two Foot Tunnel.
