A fire retardant ligno-cellulosic panel made from a mixture of (i) ligno-cellulosic material, (ii) at least one polymeric binder resin, and (iii) fire retardant solid particles containing fire retardant inorganic materials and a synthetic polymeric material, wherein the mixture is consolidated under heat and pressure to form the panel. Preferably, the fire retardant solid particles are a fine particle size sanding dust produced during the manufacture and finishing of synthetic particle filled resin materials.

Fire retardant ligno-cellulosic composite materials and a method for making the same

A method of making an aluminum hydroxide and melamine blend. The method comprises jet milling a quantity of coarse particle size melamine until a line particle size melamine is obtain which has a median particle size of from about 0.5 .mu.m to about 45 .mu.m, passing the fine particle size melamine through an air classifier and a cyclone separator, and admixing the fine particle size melamine with a quantity of surface treated aluminum hydroxide in a high speed mixer.
