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.
La présente invention se rapporte à une composition ignifuge et à un procédé de fabrication de matériaux cellulosiques ignifuges comprenant la composition ignifuge. L'invention se rapporte plus spécifiquement à des compositions liquides, comprenant des compositions liquides comprenant de l'urée et un composé contenant du bore pour rendre les produits cellulosiques ignifuges. Le composé contenant du bore comprend typiquement des acides boriques; des borates (c'est-à-dire, des sels d'acide borique); des oxydes boriques (c'est-à-dire, tout composé contenant du bore et de l'oxygène), et des mélanges de ceux-ci.
