## Abstract

A method for creating a mixture for fire prevention and suppression, comprising introducing phosphoric acid and anhydrous ammonia gas into a reactor, then introducing urea into the reactor in a controlled rate to achieve a pH of the mixture is 7+/−0.1. Next amino functionalized siloxane is introduced into the mixture, and then powdered volcanic ash (pumice) is introduced. The powdered volcanic ash is introduced into the mixture by means of a turbo-shear high performance mixer. The resulting URAP can be sprayed as fire prevention coating onto vegetation, structural buildings, lumber material and/or other combustible structures. The URAP mixture performs as a fire suppressant by coating substrates and starving combustion's necessary oxygen access.

## Claims

### Claim 1

A method for creating a mixture for fire prevention and suppression, comprising:
introducing phosphoric acid and anhydrous ammonia gas into a reactor;
monitoring the mixture until a pH for the mixture stabilizes between 6.4 to 6.7;
introducing urea into the mixture wherein the pH of the mixture is 7+/−0.1; and
introducing amino functionalized siloxane into the mixture.

### Claim 2 (depends on 1)

The method of claim 1, wherein:
an amount of the urea introduced into the mixture is between 1% to 15% weight per volume.

### Claim 3 (depends on 1)

The method of claim 1, wherein:
an amount of the urea introduced into the mixture is between 5% to 12% weight per volume.

### Claim 4 (depends on 1)

The method of claim 1, wherein:
an amount of the amino functionalized siloxane introduce into the mixture is between 0.1% to 15% weight per volume.

### Claim 5 (depends on 1)

The method of claim 1, wherein:
an amount of the amino functionalized siloxane introduce into the mixture is between 2% to 5% weight per volume.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
introducing powdered volcanic ash into the mixture;
wherein the powdered volcanic ash is introduced into the mixture by means of a turbo-shear high performance mixer.

### Claim 7 (depends on 6)

The method of claim 6, wherein:
an amount of the volcanic ash introduced into the mixture is between 1% to 15% weight per volume.

### Claim 8 (depends on 6)

The method of claim 6, wherein:
an amount of the volcanic ash introduced into the mixture is between 5% to 10% weight per volume.

### Claim 9

A mixture for fire prevention and suppression, comprising:
phosphoric acid, anhydrous ammonia gas, urea, amino functionalized siloxane and powdered volcanic ash;
wherein a pH of the mixture is 7+/−0.1;
wherein an amount of the urea introduced into the mixture is between 1% to 15% weight per volume;
wherein an amount of the amino functionalized siloxane introduce into the mixture is between 0.1% to 15% weight per volume; and
wherein an amount of the volcanic ash introduced into the mixture is between 1% to 15% weight per volume.

### Claim 10

A method for creating a mixture for fire prevention and suppression, comprising:
introducing phosphoric acid and anhydrous ammonia gas into a reactor;
introducing urea into the mixture;
introducing amino functionalized siloxane into the mixture; and
introducing powdered volcanic ash into the mixture;
wherein the powered volcanic ash is introduced by means of a turbo-shear high performance mixer.

### Claim 11 (depends on 10)

The method of claim 10, further comprising:
introducing psyllium into the mixture;
wherein a pH of the mixture is 7+/−0.1;
wherein an amount of the urea in the mixture is between 5% to 12% weight per volume;
wherein an amount of the amino functionalized siloxane in the mixture is between 2% to 5% weight per volume; and
wherein an amount of the volcanic ash in the mixture is between 5% to 10% weight per volume.
