Description

A kind of environment-friendly type aqueous film-forming foam extinguishing agent
Technical field
The present invention relates to extinguishing chemical Material Field, and in particular to a kind of environment-friendly type aqueous film-forming foam extinguishing agent and its preparation side Method.
Background technology
Fluorine is electronegativity highest element in nature, so the covalent bond of carbon-fluorine (C-F) key has the property of ionic bond Can, bond energy is very high, up to 452kJ/mol, and because the atomic radius of the fluorine atom of covalent bonding is bigger than oxygen atom, can be effectively By fluoridized C-C keys shielding protection, therefore by contrast, fluorine-containing surfactant has good chemical stability and heat steady It is qualitative.
Because the water-soluble liquid energy of fluorine-containing surfactant sprawls this unique property on pasta, in fluorine-containing surfactants In many applications of agent, most strikingly can as aqueous film-forming foam extinguishing agent (AFFF) main component.MJPZ steeps The fire extinguishing function of foam extinguishing agent is mainly what is taken on jointly by the froth bed and water film that float on pasta.When the water prepared When film-forming foam is ejected into fuel oil surface, the rapid drawout on pasta of foam meeting, while foam gradually separates out liquid to cool down Pasta.The liquid of precipitation also transforms into water membrane on pasta upper berth, and EVAP is suppressed jointly with froth bed.And the aqueous solution The effect of sprawling can also drive foam to flow to the region not yet put out a fire rapidly and further put out a fire.Therefore aqueous film-forming foam extinguishing agent Dual extinguishing ability becomes one kind of oils fire extinguishing people's favor the most by it.Aqueous film-forming foam extinguishing agent is lived by fluorochemical surface Property agent, hc-surfactant and improve the additives of foaming properties and (foam stabiliser, thickening agents, anti-burning agent, antifreeze, help Solvent, cosolvent, cushioning liquid and bacteriostatic agent etc.) and water composition.
But it is expensive because fluorine surfactant synthesizes difficult, make aqueous film-forming foam extinguishing agent be difficult to promote.It is existing Aqueous film-forming foam extinguishing agent containing sustainable organic pollution (POPs) by United Nations Environment Programme because being limited.U.S. etc. Western countries use in total ban in 2015, and China interior over the next several years will also gradually decrease and finally thoroughly forbid containing POPs fire foam.The U.S. have developed corresponding substitute, but its technology is holded in close confidence, and product price is very high It is expensive, it is ten times of existing aqueous film-forming foam extinguishing agent.
