Description
Technical field
The present invention relates to a kind of extinguishing chemical and preparation method thereof, be specifically related to the preparation method of novel anti dissolubility aqueous film-forming foam extinguishing agent.
Background technology
Both at home and abroad extinguishing chemical was required gradually in characteristics such as environmental protection, multi-functional, high efficiency in recent years, the extinguishing chemical great majority that China produces are dry powder, and powder extinguishing agent has tangible limitation, not can do with the large tracts of land fire, do not possess anti-resume combustion ability yet, human body is had injury.
Present non-fusibility aqueous film-forming foam extinguishing agent only is applicable to mixing of fresh water and puts out a fire, and does not put out a fire and be suitable for sea water mixing.Such non-fusibility aqueous film-forming foam extinguishing agent, its selected fluorocarbon surfactant and anti-character of burning agent, be not suitable for and sea water mixing, in case extremely unstable with the performance of sea water mixing fluorocarbon surfactant and the agent of anti-burning, very big to foaming properties and extinguishing property influence.
Summary of the invention
Technical problem solved by the invention is to provide the preparation method of novel anti dissolubility aqueous film-forming foam extinguishing agent, to solve the shortcoming in the above-mentioned background technology.
The non-fusibility aqueous film-forming foam extinguishing agent, this product combination prescription is by weight: compound anti-burning agent 300-400 part, Sodium Benzoate 6-10 part, urea 50-100 part, xanthans 5-9 part, Cocoamidopropyl betaine 200-400 part, APG 20-40 part, ethylene glycol 80-200 part, butyl glycol ether 30-60 part, F1157 10-30 part, F1203 20-60 part, F1268 10-30 part, buffer 20-50 part.
In the present invention, the non-fusibility aqueous film-forming foam extinguishing agent, the best of breed prescription of this product, by weight: 350 parts of compound anti-burning agent, 80 parts of Sodium Benzoates, 70 parts in urea, 7 parts of xanthans, 300 parts of Cocoamidopropyl betaines, 30 parts of APG, 150 parts of ethylene glycol, 40 parts of butyl glycol ethers, 40 parts of 20 parts of F1157, F1203,20 parts of F1268,30 parts of buffers.
The preparation method of non-fusibility aqueous film-forming foam extinguishing agent: start mixer, add compound anti-burning agent 300-400 part, add Sodium Benzoate 6-10 part, urea 50-100 part makes its whole dissolvings, adding xanthans 5-9 part all dissolves, stop to stir, behind swelling 1h～3h, continue to stir adding Cocoamidopropyl betaine 200-400 part, APG 20-40 part, ethylene glycol 80-200 part, butyl glycol ether 30-60 part, evenly be added dropwise to F1203 20-60 part successively, F1157 10-30 part, F1268 10-30 part, stir 30min～60min, adjust the pH value 7.5-8.0 of material, add buffer 20-60 part, continue to stir 10min～30min, stop to stir, then through sedimentation, packing gets final product.
In the present invention, compound anti-burning agent is with the anion fluorocarbon surfactant under agitation, is added drop-wise in the aqueous solution of cationic polymer, makes it to carry out compound.
In the present invention, low molecular weight fluorinated surfactant F1268 can effectively reduce the viscosity of non-fusibility aqueous film-forming foam extinguishing agent, can seal burning steam fast simultaneously, reaches quick extinguishing.
In the present invention, both sexes fluorocarbon surfactant F1157, F1203 they in prescription, reduce surface tension, control blow-off velocity, improve burn resistance can best usage ratio be 1:2;
In the present invention; xanthans is a kind of macromolecular material; on polar solvent, form a kind of gelinite protective layer; it is unaffected that upper foam is protected; it has the effect of good stable foam performance; with Cocoamidopropyl betaine; both sexes fluorocarbon surfactant F1157; F1203; low molecular weight fluorinated surfactant F1268; material compatibilities such as compound anti-burning agent are good; the sea water resistance performance is good; product and seawater; foaming properties and extinguishing property change very little after the mixing of fresh water; this product foaming properties is stable; be applicable to fresh water; the sea water mixing fire extinguishing; the fire-fighting efficiency height, blow-off velocity is fast, and burn resistance can be good; storage period is long, and advantage such as preparation technology is simple.
In the present invention, make novel anti dissolubility aqueous film-forming foam extinguishing agent be applicable to seawater, fresh water, effectively put out a fire with seawater or mixing of fresh water, select compound anti-burning agent, low molecular weight fluorinated surfactant F1268 can adaptation and seawater, mixing of fresh water put out a fire.
In the present invention, after compound anti-burning agent and low molecular weight fluorinated surfactant F1268 and seawater or the mixing of fresh water, its capillary performance variation that reduces the aqueous solution is very little.Compound anti-burning agent is a kind of good hydrophilic and oleophobic stabilizing agent, the heat-resisting burn resistance of foam can be strengthened, it is to be combined into polymer composite by cationic polymer and anion fluorocarbon surfactant, and after its aqueous solution and seawater or the mixing of fresh water, its foaming properties changes very little.After using these two kinds of materials, foaming properties and extinguishing property change very little after novel anti dissolubility aqueous film-forming foam extinguishing agent and seawater, the mixing of fresh water.
In the present invention, compare with existing non-fusibility aqueous film-forming foam extinguishing agent:
After sea water mixing, the coefficient of foaming height, long, the foam stabilization of 25% drainage time, blow-off velocity is fast, attack time is short, and foam good heat resistance, 25% anti-burning time are long, and the product storage period is long.
Non-fusibility aqueous film-forming foam extinguishing agent before and after improving contrasts as following table:
Beneficial effect:
The product of patent manufacturing of the present invention has with low cost, both has been applicable to that fresh water also is applicable to seawater, and is very little by foaming properties and extinguishing property variation after use mixing ratio and seawater or the mixing of fresh water, the coefficient of foaming height, and 25% drainage time is long, foam stabilization.In go out alcohols when fire, foam, form a kind of gelinite protective layer on polar solvent; it is unaffected that upper foam is protected; during alcohols fire or the oils of going out fire; blow-off velocity is fast, can seal burning steam fast; reach quick extinguishing, attack time is short, and foam good heat resistance, 25% anti-burning time are long; the product storage period is long, and advantage such as preparation technology is simple.
