On the other hand, the present invention also provides a kind of preparation method of sea water resistance type non-fusibility aqueous film-forming foam extinguishing agent, comprises the following steps: at first, start mixer, add deionized water 300-400 part, add Sodium Benzoate 6-10 part, urea 20-80 part to make its whole dissolvings; Then, after adding xanthans 5-9 part all to dissolve, stop stirring, after swelling 1h～3h, continue to stir and add Cocoamidopropyl betaine 100-400 part, APG 20-60 part, ethylene glycol 80-200 part, butyl glycol ether 20-60 part, add uniformly successively again F1203 10-50 part, F1157 10-50 part, F1460 10-60 part, and stirring 30min～60min, adjust the pH value of material to 7.3-7.8, add buffer 20-60 part, continue to stir 10min～30min, stop stirring; Finally, will after above-mentioned solution sedimentation, pack, obtain sea water resistance type non-fusibility aqueous film-forming foam extinguishing agent.
According to a preferred embodiment of the invention: in the method, each component is counted by weight: 350 parts of deionized waters, 8 parts of Sodium Benzoates, 30 parts, urea, 6 parts of xanthans, 30 parts of 200 parts of Cocoamidopropyl betaines, 30 parts of APG, 120 parts of ethylene glycol, 30 parts of butyl glycol ethers, 25 parts of FC1157,25 parts of FC1203,30 parts of F1460 and buffers.
According to a preferred embodiment of the invention: in the method, the ratio of described F1157 and F1203 is 1:1.
Compared with prior art, beneficial effect of the present invention is as described below.
1, the F1460 that has adopted du pont company to produce, it can effectively reduce viscosity 30% left and right of non-fusibility aqueous film-forming foam extinguishing agent, can also accelerate blow-off velocity, shortens attack time 1/3rd; It not only is applicable to fresh water but also be suitable for seawater, with seawater or mixing of fresh water foaming, can seal fast polar solvent burning steam, reaches the quick extinguishing purpose.
2, adopt both sexes fluorocarbon surfactant F1157, F1203, they reduce surface tension, control blow-off velocity, the raising ability of anti-burning of solution in formula.
3, because xanthans is a kind of macromolecular material, form a kind of gelinite protective layer on polar solvent, upper foam is effectively protected unaffected, it has the effect of good stable foam performance, Cocoamidopropyl betaine, the APG APG, both sexes fluorocarbon surfactant F1157, F1203, and the material compatibilities such as F1460 that du pont company is produced are good, the sea water resistance performance is strong, product and seawater, after mixing of fresh water, foaming properties and extinguishing property change very little, this product foaming properties is stable, be applicable to fresh water, the sea water mixing fire extinguishing, fire-fighting efficiency is high, blow-off velocity is fast, ability of anti-burning is good, storage period is long, and the advantages such as preparation technology is simple.
4, adopt the mode of multiple hydrocarbon surface-active combination, use two kinds of hydrocarbon surface-active combinations of Cocoamidopropyl betaine and APG APG, can mutually learn from other's strong points to offset one's weaknesses like this, more be adapted to fresh water, seawater, also be adapted to the mutual supplement with each other's advantages of foaming properties under low temperature, high-temperature condition; Because Cocoamidopropyl betaine is to belong to amphoteric surfactant, the APG APG is to belong to nonionic surface active agent, makes them under the solution state of meta-alkalescence or slant acidity, can keep good foam solution performance.
