Abstract

A low temperature flameless aerosol producing fire extinguishing composition containing potassium nitrate and binding fuel is characterized by using cellulose-fibrous mass as a binding fuel, with potassium nitrate at 30-70% and fibrous cellulose mass making up the remainder. A production method for the composition is further provided.

Claims

1. A low temperature flameless aerosol producing fire-extinguishing composition comprising potassium nitrate and binding fuel, wherein as a binding fuel, cellulose-fibrous mass is present, in the following ratio, in mass percentage:

potassium nitrate from 30-70%

cellulose-fibrous mass remainder

2. The composition of claim 1, comprising paper as a cellulose-fibrous mass.

3. The composition of claim 1, comprising cotton cloth as a cellulose-fibrous mass.

4. The composition of claim 1, comprising water soluble copper and/or iron (III) nitrates as combustion catalysts.

5. A production method for a low temperature flameless aerosol producing composition, wherein when cellulose fibrous mass is swelling in hot saturated water solution it soaks in potassium nitrate, followed by removal of excess water to 40-60% moisture content and drying to 1-2% moisture.

6. The production method of claim 5, wherein products from the composition are formed to needed size and shape.

7. The production method of claim 6, wherein formation of the product is achieved through winding previously dried by forced hot air to 1-2% moisture content sheets into rolls of required diameter.

8. The production method of claim 6, wherein formation of the product is achieved by form pressing, using hydraulic press with a matrix heated to 90-95°

C., applying 30-150 Mpa pressure, followed by drying the product to 1-2% moisture content.

9. The production method of claim 6, wherein formation of the product is acomplished using smooth or ribbed rolls heated to 80-100°

C. by gathering and drying to 1-2% moisture content a “

sock”

'"'"' made from the material that is periodically cut, removed from the tool and then wound into rolls of the required diameter.

10. The production method of claim 5, wherein during saturation of the cellulose-fibrous mass with potassium nitrate, the combustion catalyst is added, chosen from copper and/or iron(III) nitrates.

11. The production method of claim 5, wherein after drying and/or forming products to the required size and shape with 1-2% moisture content, the surface of the products is treated with hydrophobing agent such as lacquer with thickness of dry film 50-80 micron.

12. The production method of claim 11, wherein the lacquer used for hydrophobing the products'"'"' surface comprises nitrocellulose or epoxy lacquer.
