Description
Technical field
The present invention relates to extinguishing chemical technical field, in particular to it is a kind of with fluorocarbon chain length be 4 carbon Anion Gemini
The water-based extinguishing agent of type fc-surfactant production.
Background technique
Water-based extinguishing agent be the eighties since come a kind of efficient fire-extinguishing agent for growing up, this kind of fire foam
Main component is formulated by surfactant and stabilizer, cosolvent, antifreeze, fire retardant, gas generating agent and water.When by water system
When extinguishing chemical is ejected into the pasta of burning, foam can form water membrane, inhibit the evaporation of oil product in pasta rapid deployment
And completely cut off air, to achieve the purpose that put out oil product burning.Fire foam used at present contains PFOA/PFOS class mostly
Fluorine-containing surfactant is big to environmental hazard although effect is good；Part is free of the fire extinguishing of this kind of fluorine-containing surfactant
Agent, containing fluorination albumen in formula, extinguishing effect can not reach perfect condition.Compounding is a kind of not to contain lasting organic contamination
The fluorine-containing water-based extinguishing agent of object is very necessary.
Contain PFOS or PFOA in the fluorine-containing surfactant generally used in existing water-based extinguishing agent, contains long perfluor alkane
The fluorine-containing surfactant of base chain also have the biological metabolism stability of height, remote migration characteristic, high bioconcentration,
And potential bio-toxicity, extensive concern is caused in terms of environment and ecological protection.Such as perfluoro octyl sulfonic acid
(PFOS) and its world derivative Yi Bei Convention of Stockholm is classified as one of lasting organic pollutant (POPS), be restricted and
It is forbidden to use.Surfactant of the others containing perfluor long alkyl chain such as perfluoro caprylic acid (PFOA) and its derivative application and
Bring Environmental and ecological problems are also by the great attention of people.Develop under existing national industrial policies and the above international background
Using novel environmentally friendly fluorine-containing surfactant, substitution contains long-chain perfluoroalkyl fluorine-containing surfactant, has
Important economy and society meaning, is trend of the times.
Existing water-based extinguishing agent is in production preparation by a certain proportion of water, fire retardant, antifreeze, surface-active
The substances such as agent, couplant are mixed in a certain ratio together, carry out premix use with water by a certain percentage again in use, or straight
Connect filling use.Due to be liquid condition make this be extinguishing chemical in transport that there is volumes is big, weight is big, packing cost is high
Etc. disadvantages.Water is traditional firing-fighting medium, but also results in water in solid since the surface tension of Natural Water is big, mobility is excessively good
The certainty problem such as poor adhesive force on substance.Some researches show that have 80% water due to above by vain in fire extinguishing procedure
It slatterns, this is more and more not received under current water resource distant view background increasingly in short supply.In resource occupation and
Under the social concern overall background that environmental pollution is getting worse, water-based extinguishing agent is to have very by force due to the characteristic itself of itself
Plasticity, but the problems such as existing water-based extinguishing agent is due to formula and itself physicochemical property, generally need to consider packaging and
Transportation cost certainly will just be caused along with extinguishing grade of fire-fighting authoritative department in China's for water-based extinguishing agent is of less demanding
The low problem of the fire-fighting efficiency of water-based extinguishing agent in use.This also annoyings this industry of water-based extinguishing agent and fire-fighting
The use of department.
Existing research the result shows that, when in fluorinated surfactant fluorocarbon chain length be 4 carbon when, just do not have bioaccumulation
Property and persistent environmental harm.But when fluorocarbon chain length is 4 carbon in fluorinated surfactant, the fluorinated surfactant of traditional structure
Critical micelle concentration is very high, and surface tension is higher.
Twin type surfactant (gemini surfactants) be a kind of band there are two hydrophobic chain, two hydrophilic groups and
The compound of one bridged group.It is compared with conventional surfactant, twin type surfactant has very high surface-active,
Its aqueous solution has special phase behavior and rheological characteristic, has caused broad interest and the concern of academia and industry personage.It is existing
There is the not research for the surfactant that fluorocarbon chain length is 4 carbon in water-based extinguishing agent in technology.
Summary of the invention
