Definitions
- the concentrate may also contain solubilizing agents.
- solubilizing agents UNITED STATES PATENTS Ahlbrecht ..260/561 X 7 Claims, No Drawings FIELD OF INVENTION
- the invention relates to fire extinguishing foam concentrates which contain water and an organic fluor compound.
- fires particularly fires of fuels and propellants, are combatted by spraying foam in the form of continuous coats or coverings.
- foam blankets are also suitable for preventing the initial formation of fires.
- Suitable prior art foaming agents for such purposes are prepared from protein salts, as for example from keratins, albumins, seed flour and the like which are modified by hydrolysis and stabilized with certain preselected metal salts.
- foaming agents produced from protein hydrolysates cannot successfully be used for the combatting of certain types of fires.
- foaming agents are not suitable for fighting fuel fires or fires of polar substances as, for example, alcohol fires.
- a further drawback of these known foaming agents resides in the fact that they are incompatible with dry fire extinguishing powders which are customarily used simultaneously, particularly if the powders have silicon containing surfaces. If such prior art foaming agents are used in conjunction with dry fire extinguishing powders, the foam has a tendency to collapse.
- foaming agents which are water soluble, ion-active derivatives of a fluorocarbonor a fluorosulfonic acid. Such compounds are usually applied in the form of an aqueous master solution. Concentrates of this kind have been described, for example, in German Pat. No. 1,2 16,1 16. However, also the latter type of prior art foaming agents is not fully satisfactory.
- the prior art fluorocarbon-tensides do not readily form stable aqueous foams of high expansion rate.
- the inventive fire extinguishing foam concentrate is characterized in that it comprises about 1 to by weight of compounds of the general formula wherein a is a number having the value of from one to three inclusive X is hydrogen or Y and Y stands for a hydrophilating group, particularly polyethyleneglykol or a group containing an aminoxyd or ammoniumsalt group.
- the concentrate may advantageously contain a sufficient amount of a solubilizing agent in order to render the concentrate water soluble.
- the fluororganic compounds contained in the concentrate are water soluble. In the event that they are soluble with difficulty only or are substantially insoluble, they may be converted into water miscible form by the addition of a solubilizing agent of a nature known per se.
- solubilizing agents may be used for this purpose.
- triethanolammoniumlaurylsulfate, triethanolammonium dodecylbenzenesulfonate as well as the various ionogenic and nonionogenic tensides with HLB values above 12 are suitable for the indicated purpose.
- the operational characteristics of the fluoro compounds used in the inventive fire extinguishing foam concentrate may in some instances be favorably influenced by by the addition of preselected solubilizing agents.
- solubilizing agents for this purpose the addition of water soluble polysiloxanes has proved to be particularly favorable.
- Such water soluble polysiloxanes, acting as solubilizing agents for the inventive purposes are, for example, polysiloxane-polyalkyleneglykol-mixed block-copolymers as well as polysiloxanes which contain ionogenic groups linked to SiC, for example, organofunctional sulfates of polysiloxanes as disclosed, for example, in German Pat. No. 1,179,937.
- solubilizing agents of the following formula are particularly suitable within a compound mixture, up to 50 mole of trimethylsilyl may be replaced by alkyl, preferably lower alkyl.
- R is aryl or alkyl.
- phenyl is the preferred aryl group.
- R is alkyl
- the preferred alkyl group is methyl.
- Another preferred alkyl group is tri-yyy-trifluoropropyl.
- R may be different within the same siloxane group.
- some phenyl groups or trifluoropropyl groups may be present.
- the group R moreover, may be trimethylsiloxy.
- n stands for zero or one.
- the organosilicon compound is comprised of a sulfate group which is linked to the siloxane group through a carbon bridge. However, if n 0 then the organosilicon compound is a sulfonate.
- m has a value of from one to three, preferably one to 1.3.
- nonionogenic siloxanetensides of the following general formula E II
- R, R and m have the same meaning as indicated above.
- R is hydrogen, alkyl or aryl. If R is aryl then phenyl is the preferred group; if R is alkyl, lower alkyl is preferred.
- M stands for In the latter group, I has a value of from one to three.
- u has a value offrom seven through 30.
- organosilicon solubilizing agents have the par ticular advantage that they contribute not only to the solu' bilization but also significantly contribute to the formation of an effective fire extinguishing foam proper.
- HVT in the Table stands for half value time and indicates the time period which passed until an amount of liquid had been reformed which corresponded to one half of the original amount.
- the height of the foam was measured in millimeters.
- the foam which was produced according to this foam impact method in tap water of about 10 German hardness was also used for extinguishing gasoline, supergasoline and butanol fires.
- ccm. of these liquids were in 2) each case fed to a pot of 14.5 cm. diameter.
- the liquids were or the group then ignited and after a burning time of 2 minutes the extinguishing or fire combatting procedure was initiated.
- the U T results are tabulated in Tables Ila l to Ila 3, [lb 1 to 11b 3 and CH3 He 1 to He 3.
- a is a number having a value of from one to three inclusive
- X is hydrogen or Y and Y is a hydrophilating group; said concentrate additionally containing a solubilizing agent in an amount sufficient to render the concentrate water soluble, said solubilizing agent having an hlb value above 12.
- solubilizing agent is triethanol ammonium laurylsulfate, triethanol ammonium dodecyl benzene sulfonate, an ionogenic tenside or a non-ionogenic tenside.
- hydrophilating group Y is polyethyleneglyko] or a group containing aminoxide or ammoniumsalt.
- the active ingredient is a compound of the general formula (CHs)a S i0 Si(CHa)a said agent being contained in the concentrate in an amount by weight corresponding to three to 15 times the quantity of said active ingredient.
