Composition of a wood combustion inhibitor based on a magnesium complex containing phosphorus and nitrogen

详细

A flame retardant for wood impregnation based on a magnesium complex containing phosphorus and nitrogen was developed. It considerably reduces the wood loss in fire tests. Application of the flame retardant in an amount of 300 g m^–2 allows preparation of materials with the fire performance corresponding to group I of materials. The mechanism of the fireproofing action of the flame retardant on wood and the thermal degradation of the impregnated wood were studied.
