Abstract

A fire suppression composition and method of encapsulation, thermal runaway prevention is provided. The fire suppression composition includes exfoliated vermiculite mixed with a liquid propellant, wherein the composition is chemical free, non-toxic, and biodegradable. Performance additives may be optionally added to improve the performance of the fire suppression composition. The fire suppression composition is intended for a variety of uses, and fire fighting systems. Although it may be used to fight a variety of fires, it is particularly useful for lithium ion battery fires. The exfoliated vermiculite is configured to encapsulate the object or substrate on fire, preventing thermal runaway and escalating fire situations.

Claims (16)

1 . A fire suppression composition comprising:

particle reduced thermally exfoliated vermiculite in powdered form having a particle size ranging from 5-100 micrometers;

a liquid propellent;

a fire retardant hydrocolloid additive;

a nitrogenous phosphate salt; and,

wherein the fire suppression composition is biodegradable.

2 . The fire suppression composition of claim 1 , wherein the fire suppression composition comprises 5-20% thermally exfoliated vermiculite and 80-95% liquid propellant by weight.

3 . The fire suppression composition of claim 1 , wherein the liquid propellant is water.

4 . The fire suppression composition of claim 1 , further comprising an adhesive, wherein the adhesive is configured to reduce an amount of thermally exfoliated vermiculite needed for the composition.

5 . The fire suppression composition of claim 4 , wherein the fire suppression composition comprises 1-10% thermally exfoliated vermiculite and 90-99% liquid propellant by weight.

6 . The fire suppression composition of claim 1 , wherein the fire suppression composition is configured to be held within a fire extinguisher tank or a tank positioned in a vehicle.

7 . The fire suppression composition of claim 1 , further comprising a stabilizing resin, wherein the stabilizing resin is non-toxic, non-flammable, and biodegradable.

8 . A fire suppression composition configured to extinguish a fire on an object, the fire suppression composition comprising:

particle reduced thermally exfoliated vermiculite in powdered form having a particle size ranging from 5-100 micrometers;

a liquid propellent; and

an adhesive.
