Description
Technical field
The invention belongs to technical field of fire control, and in particular to a kind of ultralow temperature fire foam.
Background technology
Extinguishing chemical is to refer to effectively destroy burning condition, terminates the material of burning.Fire foam be a kind of volume compared with
It is little, the bubble population that surface is surrounded by liquid, proportion is between 0.001～0.5.Because the proportion of foam is far smaller than general flammable
The proportion of liquid, thus the surface of liquid can be floated on, form a foam blanket.Meanwhile, foam has certain again
Viscosity, can adhere to the surface of general flammable solid.The foam blanket that fire foam is formed on comburant surface, can make combustion
Burn thing surface and air insulated.In prior art, ultralow temperature fire foam has the disadvantages that：First, due to flame combustion
Temperature is higher, and usual fire scene temperature reaches more than 1100 DEG C so that when fire foam is sprayed onto on ignition point, extinguishing chemical moment quilt
Evaporation, so as to not reach covering buffer action, affects fire extinguishing, therefore, need to be until ignition temperature be reduced, the bubble that extinguishing chemical is produced
Foam ability stable existence, ability quick extinguishing, and temperature reduce absorbing heat by moisture evaporation, and cooling effect is bad so that
Blow-off velocity is slower, meanwhile, at subzero 50 degrees Celsius, extinguishing chemical is solidified the fire foam of prior art so that cannot
Suitable for low temperature environment, its adaptability is weaker；Second, the refrigerating material of existing ultralow temperature extinguishing chemical is in order to reach ultralow temperature system
Cold effect, what is had still can be using R-13 as super low temperature refrigeration agent, i.e. Freon 13, because R-13 belongs to CFC class things
Matter（First limited ODS substance C lass I Ozone-depleting Substances）--- ozone layer is had destruction,
And there are greenhouse effects, cause environmental disruption.Certainly, there is the addition triethanolamine phosphorus in ultralow temperature fire foam on market
Acid esters, its principle be by the photon that discharges during its absorption burning, cut off luminous energy to heat energy convert by way of controlling combustion
The temperature of reaction release is burnt, ignition temperature moment is reduced to below burning-point, reach quick extinguishing effect, then by fully wetting
Infiltration emulsification combustible, in the middle of combustible and froth bed thin film is formed, and reaches starvation, nips off burning chain reaction
The purpose rapidly put out a fire, blow-off velocity is fast and not resume combustion.Additionally, the triethanolamine phosphate for adding can be reduced to freezing point
Subzero 50 degrees Celsius, it is ensured that in low temperature environment, do not freeze, enhance the boisterous adaptability of extinguishing fluid.But added with
There is extinguishing chemical material mixture ratio in the ultralow temperature fire foam of triethanolamine phosphate, not good to there is extinguishing chemical unstable
Problem, the time one is grown, and its extinguishing effect can relatively low or even failure.
The content of the invention
It is an object of the present invention to provide a kind of ultralow temperature fire foam, using environment-friendly type super low temperature refrigeration material, it is adaptable to
Low temperature environment, the extinguishing chemical environmental protection for obtaining, and long-time stable, effectively.
In order to realize object above, the technical solution used in the present invention is：A kind of ultralow temperature fire foam, according to weight
The raw material of percentage includes：Diethylene glycol monobutyl ether 3 ~ 5%, compounding fluorocarbon surfactant 6 ~ 10%, Sodium Benzoate 10 ~ 15%, into

The method have technical effect that：Refrigerating material is belonged to using fluoroform and carbon dioxide, wherein fluoroform
HFC class materials（Non- ODS materials Ozone-depleting Substances）--- therefore do not damage the ozone layer completely, have
The characteristics of cleaning, low toxicity, good extinguishing effect；Carbon dioxide is nature naturally occurring material, ODP=0, GWP=1. wide material sources,
With low cost, CO2 safety non-toxics are non-combustible, even if under do not decompose generation pernicious gas yet.The evaporation latent heat of CO2 is larger, unit
Volume refrigerating capacity compressor is at a relatively high, therefore compressor and part dimension are less.Triethanolamine phosphate can be reduced to freezing point subzero
50 degrees Celsius, it is ensured that in low temperature environment, do not freeze.Diethylene glycol monobutyl ether plays stabilizer function.Using above-mentioned material proportioning
The ultralow temperature foam fire-fighting agent material for obtaining afterwards, it is adaptable to low temperature environment, the extinguishing chemical environmental protection for obtaining, and long-time stable, have
Effect, the term of validity was up to 5 years as long as.
