Specification of Letters Patent.
Serial no. 425,031.
To all whom'it'may concern: 0
Be it known that I, Gmno BLENIO, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certam new and useful Improvements in Fireproofing Solu tions, of which the following is a descrlption.
My invention relates to fire proofing solutions for treating fabrics, wood, or other fibrous materials to render them proof against fire, and has for its object to prov1de a solution for this purpose which will be effective to render the material treated flame and glow proof without injury to the material, even delicate fabrics, as regards tensile strength or as regards the colors with which the fabric or other material may be dyed or printed, and will at the same time be inexpensive and easily applied.
With these and other objects hereinafter explainedlin view myinvention consists n the solution hereinafter described and claimed.
In preparing my solution for use on fabrics I take 100 gallons of water and (118; solve in it 15 pounds of boracic acid crystals, when this is thoroughly dissolved I add to the solution from 5 to 10 gallons of sulfur-1c acid, depending on the strength of the acid, and then add one half gallon of phosphono acid. When these ingredients are thoroughly mixed and dissolved I add strong ammonia suflicient to render the solution neutral, it
To this solution I find it desirable, though not essential, to add a. small quantity of either gum arabic or tapioca. If gum arabic is used I take for the amount of solution above described from one to five pounds of the gumarabic dissolved in water. If tapioca is used I take the dry tapioca in the proportion of one 'halfounce to each two gallons of the solution, dissolve it in cold water and cook it thoroughly andadrr the gr cooked mass to the solution. 1
To the solutionthus formed I add such amount of water as may be necessary to reduce it to a specific gravity of 12 Baum.-
This forms a stock solution. use I take from this solution such amount as may benecessary for the amount of fabric to be treated and add sufficient water to reduce the specific gravity to 8 Baum, for delicate fabrics such as lace curtains, cheese cloth or like material. F or heavier fabrics less dilution is necessary. The solution if formed of pure materials and made absolutely neutral as above explained will not injure fabrics either as regards tensile strength or color and will render them not only flame proof but also glow proof. 1
The stock solution above described is effective for fire proofing wood to which it may be applied in any of the usual methods of impregnating wood with fire proofing or preservative solutions which will cause it to be absorbed by the pores of the wood. But for fire-proofing wood I prefer to use a larger amount of boracic acid than above described and may use from 15 to 25 ounds of the boracic acid crystals instead of the 15 pounds. The solution is, however, to be rendered neutral with strong ammonia. It need not be diluted below 15 Baum for the stock solution. For use it may be diluted as desired preferably not below 8' Baum. This solution with the additional amount of boracic acid may be used on fabrics with satisfactory resultsbut the larger amount of boracic acid which is desirable for fireproofing wood to counteract any hygroscopic tendency of the sulfuric acid but is not necessary for use on fabrics. It is, however, desirable in the solution for use in fireproofing wood to add the gum arabic or tapioca, preferably the tapioca.
It will, of course, be understood that amounts of the several ingredients may be Varied somewhat, the above statement of amounts being approximate only. The new tralization of the solution is essentialand in making the solution careful tests should be 'made to determine this. It is also important to bring the solution to the specific gravity stated or substantially to such specific avity.
If it is desired to fireproof wood in con= nection with electrical apparatus w/here the wood isrequired to be as near non-conductive as possible, the sulfuric acid may be omitted, the amount of phosphoric acid beingincreased to'from 5 to 10 gallons to 100 gallons of water, the amount of boracic acid crystals used being from 20 to 25 pounds. This solution should be r'rutralized with ammonia as before described. I
\Vhile I prefer to make the stock solution of a specific gravity of 12 Baum as above stated, it may, for the purposes of transportation to avoid unnecessary amount of water, be made ofi much higher specific gravity say 20 Baum or even 25 Baum. This stronger solution should, on receipt at place at which it is to be used, be reduced to 12 Baum by the addition of the necessary amount of water.
Any of the fire-proofing solutions above described when rendered-absolutely neutral as described, particularly if not of a specific.
gravity of over 12 Baum, may be used without injury to the hands of workmen. It is also antiseptic.
Having thus described my invention what I claim is:
1. A solution for fireproofing resulting from 'a mixture of sulfuric acid, boracic acid and phosphoric acid with just suflicient ammonia to render the solution neutral.
2. A solution for fireproofing resultingfrom a mixture of sulfuric acid, boracic acid, phosphoric acid and tapioca with just sufficient ammonia to render the solution neutral.
3. A solution for fireproofing resulti ng from a mixture of sulfuric acid, boracic acid,
Sulfuric acid 5 gallons. Boracic acid crystals 15 pounds. Phosphoric acid 10 gallons.
Water 100 gallons.
Ammonia: Just sufficient to render I the solution neutral.
- In testimony whereof I afiix my signature this 10th day of January, 1919.
GUIDO BLENIO.
