A cellulose-based fire retardant composition is made by (1) adding cellulose to water, thereby forming a solution; (2) adding liquid ammonia to the solution; and (3) subsequently adding solid diammonium phosphate to the solution, thereby forming a viscous cellulose-based fire retardant liquid.

La présente invention concerne une composition ignifuge à base de cellulose fabriquée selon plusieurs étapes consistant (1) à ajouter de la cellulose à de l'eau, de manière à former une solution; (2) à ajouter de l'ammoniac liquide à la solution; puis (3) à ajouter du phosphate diammonique solide à la solution, de manière à former un liquide ignifuge visqueux à base de cellulose.
