Abstract
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.

A method of preparing a cellulose-based fire retardant composition, comprising:
- adding cellulose having a hydroxyl group to water, thereby forming a solution;
- adding ammonium hydroxide to the solution;
- subsequently adding diammonium phosphate to the solution and binding diammonium phosphate groups to the cellulose;
- and
- crosslinking the cellulose, thereby forming a cellulose-based fire retardant composition.
A method of preparing a cellulose-based fire retardant composition, comprising:
- adding cellulose powder having a hydroxyl group to liquid ammonia to form a solution;
- subsequently adding diammonium phosphate to the solution and binding diammonium phosphate groups to the cellulose;
- and
- crosslinking the cellulose, thereby forming a cellulose-based fire-retardant composition.
A cellulose-based fire retardant, prepared by:
- adding hydroxyl cellulose powder to water, thereby forming a solution;
- heating the solution;
- adding ammonium hydroxide to the solution;
- subsequently adding diammonium phosphate to the solution and binding diammonium phosphate groups to the cellulose;
- and
- crosslinking the cellulose, thereby forming a cellulose-based fire retardant liquid.
A fire-retardant cellulosic polymer made by a method comprising:
- adding one or more cellulose polymers having a hydroxyl group to water, thereby forming a solution;
- adding ammonium hydroxide to the solution;
- subsequently adding diammonium phosphate to the solution, thereby binding diammonium phosphate groups to the one or more cellulose polymers;
- and
- crosslinking the one or more cellulose polymers.
A cellulose-based fire retardant comprising one or more cellulose molecules having an oxygen atom from a hydroxyl group, wherein said one or more cellulose molecules are crosslinked by a diammonium moiety.
A method of preparing a cellulose-based fire retardant composition, comprising:
- adding cellulose having a hydroxy group to water, thereby forming a solution;
- adding ammonium hydroxide to the solution;
- subsequently adding at least one diammonium salt to the solution and binding a diammonium group to the cellulose;
- and
- crosslinking the cellulose, thereby forming a cellulose-based fire retardant composition.
A method of preparing a cellulose-based fire retardant composition, comprising:
- adding cellulose having a hydroxy group to water, thereby forming a solution;
- adding ammonium hydroxide to the solution;
- subsequently adding a polyphosphate having a diammonium group to the solution and binding the polyphosphate to the cellulose;
- and
- crosslinking the cellulose, thereby forming a cellulose-based fire retardant composition.
A method of preparing a cellulose-based fire retardant composition, comprising:
- adding one or more cellulose polymers having a hydroxy group to water, thereby forming a solution;
- catalytically binding a diammonium group to the one or more cellulose polymers in solution;
- and
- crosslinking the one or more cellulose polymers, thereby forming a cellulose-based fire retardant composition.
