Abstract

A solid-solid hybrid gas generator composition includes a solid gas generator material and a solid, flame retardant material. The flame retardant material may include one or more bromine-, chlorine- and phosphorous-containing compounds. The gas generator material and flame retardant material may be in the same vessel.

Claims

1. A solid-solid hybrid gas generator composition consisting essentially of a solid gas generator material and a solid bromine-containing flame retardant material.

2. The gas generator composition according to claim 1, wherein said flame retardant material comprises a bromine-containing compound having a bromine content greater than 58%.

3. The gas generator composition according to claim 1, wherein the flame retardant material is selected from the group consisting of tetrabromobisphenol A, tribromophenol, brominated diphenyl oxides, dibromostyrene, tetrabromophthalic anhydride, hexabromocyclododecane, and combinations thereof.

4. The gas generator composition according to claim 1, wherein the gas generator material comprises a nitrogen compound selected from the group consisting of ammonium 5-nitroaminotetrazole, triaminoguanidinium 5-nitroaminotetrazole, aminoguanidinium 5,5'"'"'-bitetrazole, and guanidinium 5,5'"'"'-bitetrazole.

5. The gas generator composition according to claim 4, wherein the gas generator material further comprises a polymer.

6. The gas generator composition according to claim 5, wherein the polymer is a copolymer of 3,3-bis(azidomethyl) oxetane and tetrahydrofuran or a copolymer of 3,3-bis(azidomethyl) oxetane and 3-nitromethyl-3-methyloxetane.

7. The gas generator composition according to claim 5, wherein a weight ratio of the nitrogen compound to the polymer is about 50:

50.

8. The gas generator composition according to claim 1, wherein the gas generator material and flame retardant material are in the same vessel.

14. The gas generator composition according to claim 1, wherein the flame retardant material is selected from the group consisting of tetrabromobisphenol A, tribromophenol, dibromostyrene, tetrabromophthalic anhydride, hexabromocyclododecane, and combinations thereof.

9. A process for suppressing a fire comprising:

producing an inert gas and a chemically-acting fire suppression agent from a composition consisting essentially of solid gas generator material and a solid, bromine-containing flame retardant material; and

applying the inert gas and the agent to the fire.

10. The process according to claim 9, wherein the produced inert gas is N₂, O₂, H₂ O or CO₂.

11. A system for suppressing a fire, comprising a vessel containing a gas generator composition consisting essentially of a solid gas generator material and a solid, bromine-containing flame retardant material.

12. The system according to claim 11, wherein the flame retardant material is selected from the group consisting of tetrabromobisphenol A, tribromophenol, brominated diphenyl oxides, dibromostyrene, tetrabromophthalic anhydride, hexabromocyclododecane, and combinations thereof.

13. The system according to claim 11, wherein the gas generator material comprises a nitrogen compound selected from the group consisting of ammonium 5-nitroaminotetrazole, triaminoguanidinium 5-nitroaminotetrazole, aminoguanidinium 5,5'"'"'-bitetrazole, and guanidinium 5,5'"'"'-bitetrazole.

15. A solid-solid hybrid gas generator composition, comprising:

a solid gas generator material; and

a solid halogen-containing flame retardant material comprising at least one of chlorine- or phosphorous-containing compounds.

16. A process for suppressing a fire comprising:

producing an inert gas and a chemically-acting fire suppression agent from a solid gas generator material and a solid flame retardant material comprising at least one of chlorine- or phosphorous-containing compounds; and

applying the inert gas and agent to the fire.

17. A system for suppressing a fire, comprising a vessel containing a gas generator composition comprising a solid gas generator material and a solid flame retardant material comprising at least one of chlorine- or phosphorous-containing compounds.
