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.
Claims12
A method of preparing a fire-retardant petroleum composition, comprising:
- adding a petroleum polymer having a hydroxyl 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 petroleum polymer;
- and
- crosslinking the petroleum polymer, thereby forming a fire-retardant petroleum composition.
