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 cold-resistant sea water resistance type 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 that China produces has fire foam and powder extinguishing agent, fire foam is applicable to mostly and mixing of fresh water foaming fire extinguishing, is not suitable for sea water mixing foaming fire extinguishing.Powder extinguishing agent has tangible limitation, the large tracts of land of can not putting out a fire to save life and property oils and alcohols fire, anti-resume combustion poor performance.
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 the cold-resistant sea water resistance type aqueous film-forming foam extinguishing agent of novel sea water resistance, to solve the shortcoming in the above-mentioned background technology.
Cold-resistant sea water resistance type 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, both sexes hc-surfactant 200-400 part, APG 20-40 part, ethylene glycol 80-200 part, butyl glycol ether 30-60 part, FC1157 10-30 part, FC1203 20-60 part, low molecular weight fluorinated surfactant 20-40 part, buffer 20-60 part.
In the present invention, the best of breed prescription of cold-resistant sea water resistance type aqueous film-forming foam extinguishing agent product, by weight: 350 parts of compound anti-burning agent, 8 parts of Sodium Benzoates, 70 parts in urea, 7 parts of xanthans, 300 parts of both sexes hc-surfactants, 30 parts of APG, 150 parts of ethylene glycol, 40 parts of butyl glycol ethers, 40 parts of 20 parts of FC1157, FC1203,30 parts of low molecular weight fluorinated surfactants, 40 parts of buffers.
The preparation method of novel anti dissolubility 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 both sexes hc-surfactant 200-400 part, APG 20-40 part, ethylene glycol 80-200 part, butyl glycol ether 30-60 part, evenly be added dropwise to FC1203 20-60 part successively, FC1157 10-30 part, low molecular weight fluorinated surfactant 20-40 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 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 FC1157, FC1203 they in prescription, reduce solution 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 the both sexes hc-surfactant; both sexes fluorocarbon surfactant FC1157; FC1203; low molecular weight fluorinated surfactant; 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 cold-resistant sea water resistance type 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 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 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 the compound anti-burning agent of macromolecule by cationic polymer and anion fluorocarbon surfactant, 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 cold-resistant sea water resistance type 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.
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 foam exquisiteness, and the coefficient of foaming height, 25% drainage time is long, foam stabilization.During the oils of going out fire, by moisture film and the fire extinguishing of foam double action, blow-off velocity is fast, and burn resistance can be good; 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, burn resistance can be strong, 25% anti-burning time is long; the product storage period is long, and advantage such as preparation technology is simple.
