FIRE-RESISTANT FIBROUS MATERIAL AND METHOD OF PRODUCING THE No Drawing.
The object of my invention is to produce a fire resistant fibrous material by the treat ment of a combustible fibrous material with a liquid mixture of a solution of a water 6 soluble magnesium salt, such, for nstance, as magnesium sulphate and a solut on of a water soluble bicarbonate, such, for instance, as potassium bicarbonate; the so treated fibrous material even when exposed to the ele- 10 ments retainin its fire resistant qual ties,
thereby rendering the treated fibrous material suitable alike for outside :51 llIislige Presu posin' g magnesium p a an otassiuih bicarbonate are to be used to prosues the liquid mixture for treating the combustible fibrous material, a solution of the magnesium sulphate ismixed with a solution of the potassium bicarbonate at normal room temperature (about centi- 0 grade) and the resultant mixture a water clear liquid which will remain without reaction for a reasonable time so long as the mixture is kept at normal room temerature.
In treating combustible fibrous material, such, for instance, as wood, render it resistant, the fibrous material istreated with the liquid mixture at substantially its normal temperature. After this treatment the fibrous material is subjected to heat, thereby releasing carbon dioxide and precipitating magnesium carbonate, which aprecipitate will render the fibrous materi permanently fire resistant even if the material is exposed to the elements, thus rendering the material suitable for outside as well as inside use. p As an example: I prepare a mixture of a 15% solution of magnesium sulphate with .a 10% stilution 08f poltlasgigm zfiizcsrbonate dkovmg' 3 gr. g r mone of cold .water and 200 gr KHCO in one litre of cold water and mixing them together at ordinary" room temperature). This water clear'liquid mixture is then used, while still cold, to treat the combustible fib teri such as w for example musm .tena1 b im regn' atin the same under heavy sli re aclosefchamber so that the h quid will be well distributed throughout the material. The im regnated-fibrous material maythen be en footed-to heat heating the material to precipitate ma substantially (p erably aga ofbfriiiilne 3013:;

carbonate throughout the material being treated, which precipitate renders the treated fibrous material fire resistant even when the material is exposed for considerable periods, to the elements. 7
Other water soluble magnesium salts which might be used are magnesium chlorate and magnesium nitrate and other water soluble bicarbonates which might be used are sodium bicarbonate and ammonium bicarbonate.
What I claim is 1. Treating combustible fibrous material with a mixture of a solution of a water soluble ma nesium salt and a solution of a water soluble bicarbonate and subsequently sium carbonate and thereby render the m a terial fire resistant.
2. Treating combustible fibrous material with a mixture of a solution of magnesium sulphate and a solution of a water soluble icarbonate' and subsequently heating the material to precipitate magnesium carbonate and thereby render the material fire resistant. p a
3. Treating combustible fibrous material with a mixture of. a solution of a water 801- uble magnesium salt and a solution of potassium' bicarbonate and subsequently heating precipitate magnesium cary render the material fire resistant.
4. Treating combustible fibrous material with a mixture of a solution of magnesium sulphate and a solution of potassium bicarbonate and subsequently heating the material to preci itate magnesium carbonate and thereby render the material fire resistant.
5. Impregnating combustible fibrous marial with a mixture of a solution of a water soluble ma esium salt and a solution of a water solub e bicarbonate-under pressure and subsequently heating the material to precipitate magnesium carbonate and thereby render the material fire resistant. p
6. Impregnating combustible fibrous-mawith a of a solution of magnesium sulphate and a solution of a water soluble bicarbonate under pressure and subsequently heating'the materialto Erecipitate magnesium carbonate and there y render the material fire resistant.
7. Impregnating combustible fibrous mawith a mixture of a solution of a water soluble magnesium salt and a solution bicarbonate under pressure and subsequently of potassium bicarbonate under pressure and heating the material to precipitate magne- 10 subsequently heatin the material to recipisium carbonate and thereby render the ma: tate magnesium car onate and there y renterial fire resistant.
5 der the material fire resistant. In testimony, that I claim the foregoing 8. Impregnating combustible fibrous maas my inventlon, I have signed my name terial with a mixture of a solution of magthis 9th day of December, 1926. nesium sulphate and a solution of potassium ALEXANDER WINOGRADOFF.
