Abstract

Systems, apparatuses, and methods are described that combine a sorbent containing a flame retardant with a substrate, which is capable of responding to temperature increases to prevent, suppress, delay the spread of, or otherwise mitigate a proximal thermal event. A flame retardant system has a flame retardant material that is incorporated into a matrical sorbent material, which is incorporated into a substrate. The matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature, e.g., a temperature that is greater than 300° C. in one embodiment.

First claim

What is claimed is:

1. A flame retardant system, comprising:
a flame retardant material incorporated into a matrical sorbent material that is incorporated into a substrate;
wherein the matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature; and
wherein the matrical sorbent material is a microporous aluminum-based Metal Organic Framework (MOF) material having a pore volume of at least 1.0 mL/g and a decomposition temperature near 300° C. to release the flame retardant material.

2. The flame retardant system of claim 1 , wherein the flame retardant material comprises huntite in combination with hydromagnesite.

3. The flame retardant system of claim 1 , wherein the flame retardant material comprises huntite in combination with aluminum hydroxide.

4. The flame retardant system of claim 1 , wherein the flame retardant material comprises huntite in combination with magnesium hydroxide.

5. A flame retardant system, comprising:
a flame retardant material incorporated into a matrical sorbent material that is incorporated into a substrate;
wherein the matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature; and
wherein the matrical sorbent material is a zirconium-based Metal Organic Framework (MOF) material having a pore volume of at least 1.0 mL/g and a decomposition temperature near 300° C. to release the flame retardant material.

6. The flame retardant system of claim 1 , wherein the MOF material comprises a thermally stable MOF having a pore volume of at least 3.0 mL/g and a decomposition temperature near 300° C. to release the flame retardant material.

7. The flame retardant system of claim 1 , wherein the MOF material comprises an isoreticular MOF having a pore volume of at least 3.0 mL/g and a decomposition temperature near 300° C. to release the flame retardant material.

8. The flame retardant system of claim 5 , wherein the matrical sorbent material comprises a zeolite material having a pore volume of at least 1.0 mL/g and a release temperature near 300° C. to release the flame retardant material.

9. The flame retardant system of claim 1 , wherein the matrical sorbent material is configured to release the flame retardant material upon exposure to a temperature that is greater than 250° C.

10. The flame retardant system of claim 1 , wherein the substrate comprises a meshed fabric.

11. The flame retardant system of claim 1 , wherein the substrate comprises a liquified coating material.

12. The flame retardant system of claim 11 , wherein the liquified coating material incorporating the flame retardant material that is incorporated into the matrical sorbent material is applied to a composite material.

13. The flame retardant system of claim 11 , wherein the liquified coating material incorporating the flame retardant material incorporated into the matrical sorbent material is applied to a solid surface.

14. The flame retardant system of claim 1 , wherein the substrate incorporating the flame retardant material that is incorporated into the matrical sorbent material comprises a cable sheath.

15. The flame retardant system of claim 1 , wherein the substrate incorporating the flame retardant material that is incorporated into the matrical sorbent material comprises a thin film arranged on a flexible tape material.

16. The flame retardant system of claim 1 , wherein the substrate incorporating the flame retardant material that is incorporated into the matrical sorbent material comprises a thin film arranged on a foil wrap material.

17. The flame retardant system of claim 1 , wherein the MOF material comprises MIL-53 having a structure with inorganic [M-OH] chains that are connected to four neighboring inorganic chains by therephthalate-based linker molecules.

18. The flame retardant system of claim 5 , wherein the zirconium-based Metal Organic Framework (MOF) material comprises one of UiO-66 or UiO-67.
