Description
Technical field
The invention belongs to fire-fighting domains, and in particular to a kind of water-based extinguishing agent.
Background technique
It is existing fire proofing to be added, filmogen is extinguishing chemical using water as matrix, although than the effect that individually fire-fights by water
Fruit is much better, and because of the difference in the selection of material, preparation method, extinguishing effect, environment influence be would also vary from.So endeavouring
It is the fire-extinguishing function concurrently and economy, ring for further promoting such extinguishing chemical in extinguishing chemical research, the department of exploitation and technical staff
Guarantor property, still in the novel composing prescription for constantly exploring extinguishing chemical.
Summary of the invention
The object of the present invention is to provide a kind of efficient water-based extinguishing agent of environment-friendly type A, B class and preparation methods, for putting out fire
Calamity, relatively existing water-based extinguishing agent significantly promote extinguishing ability and eliminate the pollution after put out a fire to environment.
It is a further object to provide a kind of preparation methods of extinguishing chemical, and the extinguishing chemical is made to become business
Change product, satisfies social needs.
Water-based extinguishing agent of the invention is made of fire retardant A, extinguishing chemical B, auxiliary agent I, auxiliary agent II, water, surfactant；
Wherein:
Fire retardant A includes: diammonium hydrogen phosphate 15-27 parts by weight, disodium hydrogen phosphate 10-22 parts by weight, dicyandiamide 8-11 weight
Measure part, borax 3-6 parts by weight；
Extinguishing chemical B includes: 2-(2- Butoxyethoxy) ethyl alcohol 15-24 parts by weight, water 5-10 parts by weight；
Auxiliary agent I includes: pull open powder 15-20 parts by weight, diffusant 10-15 parts by weight, lauryl sodium sulfate 10-15 weight
Part, neopelex 15-20 parts by weight, sodium tripolyphosphate 15-20 parts by weight, sodium bicarbonate 30-40 parts by weight；
Auxiliary agent II includes: ammonium hydrogen carbonate 100-150 parts by weight, glycerol 12-20 parts by weight, malt glucide powder 20-25 weight
Part, urea 40-50 parts by weight, salt 20-30 parts by weight；
Water consumption 1500-2000 parts by weight；
Activating agent dosage 30-40 parts by weight.
Diffusant is selected a kind of in commercial disignation CS, DAS, IW, WA, NNO diffusant.
Surfactant selects Ee507T or Ee607 or TSC2180.
It is preferable to use sodium chloride or potassium chloride for salt therein.
The preparation method of extinguishing chemical of the present invention the following steps are included:
1, diammonium hydrogen phosphate 15-27 parts by weight, disodium hydrogen phosphate 10-22 parts by weight, dicyandiamide 8-11 parts by weight, borax are taken
The mixing of 3-6 parts by weight, constitutes fire retardant A；
2,2-(2- Butoxyethoxy is taken) ethyl alcohol 15-24 parts by weight, the mixing of water 5-10 parts by weight, constitute extinguishing chemical B；
3, pull open powder 15-20 parts by weight, diffusant 10-15 parts by weight, lauryl sodium sulfate 10-15 parts by weight, 12 are taken
Sodium alkyl benzene sulfonate 15-20 parts by weight, sodium tripolyphosphate 15-20 parts by weight, the mixing of sodium bicarbonate 30-40 parts by weight, are constituted
Auxiliary agent I；
4, ammonium hydrogen carbonate 100-150 parts by weight, glycerol 12-20 parts by weight, malt glucide powder 20-25 parts by weight, urea are taken
40-50 parts by weight, the mixing of salt 20-30 parts by weight, constitute auxiliary agent II；
5, fire retardant A, extinguishing chemical B, auxiliary agent I, surfactant are mixed.
6, add the water of surplus part to step 5 gained mixture, mix；
7, the auxiliary agent II for adding step 4 to constitute into step 6 gains, mixing, is heated to 80 DEG C or more holdings 1-2 hours, cold
But high-efficiency environment friendly water system extinguishing chemical is obtained afterwards.
The extinguishing mechanism of extinguishing chemical of the present invention is: ammonium salt and disodium hydrogen phosphate in constituent, heat resolve into phosphoric acid and
Ammonia, phosphoric acid with carburization zone resistant to high temperature formed by combustion things surface, have good oxygen barrier, fire-resistant (1500 DEG C or less do not burn)
The ammonia of effect, generation is non-combustion-supporting material, is accumulated in around comburant, air-isolation.After sprinkling, extinguishing chemical is in comburant week
It encloses to form foam protective layer, by combustible and air insulated；Moisture evaporation in fire extinguishing procedure in extinguishing chemical is steamed at a large amount of water
Gas makes comburant and surrounding enviroment cool down rapidly, and the separation layer with air is formed around combustible.
The positive effect of the present invention is: extinguishing chemical of the invention, by being fire-resistant layer, flammable by comburant surface conversion
The gaseous state separation layer of combustible and air that foam protective layer, vapor and ammonia are formed is formed around object, reduces rapidly burning
The overlap action of point and a variety of fire extinguishing approach such as the vapor of temperature of surrounding moment knock down the flame and can ensure not re-ignition,
" the survey report " (N0.Gn201306988 provided according to national fixed fire extinguishing system and fire retarding component quality surveillance inspection center
Number) it can be concluded that, which is apparently higher than existing product, does not generate any environmentally hazardous decomposition product.
Moreover, relatively existing foamite amount is few, stable product quality during deposit nontoxicity, is not precipitated, free from extraneous odour, is not got damp,
Long shelf-life.
