FIRE RESISTANT CELLULOSIC MATERIALS AND METHOD OF MAKING THE SAME

摘要

The invention relates to a fire resistant composition and a method of making fire resistant cellulosic materials comprising the fire resistant composition. More specifically, the invention relates to liquid compositions, including liquid compositions comprising urea and a boron- containing compound for imparting fire resistance to cellulosic products. The boron-containing compound typically compries boric acids; borates (i.e., boric acid salts); boric oxides (i.e., any compound containing boron and oxygen), and mixtures thereof.
