Abstract
The invention discloses a kind of glue composite fire extinguishing agents, using water as base-material, add a variety of auxiliary reagents such as ammonium dihydrogen phosphate, expansible graphite, silica, hydroxyethyl cellulose, xanthan gum, by improving formula and preparation process, it is made to have the advantages that fire extinguishing effectiveness height, good flame retardation effect, anti-re-ignition effect are good compared to common extinguishing chemical.Meanwhile the ingredient safety non-pollution of extinguishing chemical of the invention, and removed conveniently after use, attachment can be removed with water.
Description
Technical field
The invention belongs to extinguishing chemical preparation technical fields, and in particular to glue composite fire extinguishing agent.
Background technique
Fire is arch enemy of man, no matter superficial fire or underground fire, not only result in a large amount of casualties, also
It will cause the heavy losses of property and natural resources.How fast and effeciently to stamp out a fire, reduces loss to the maximum extent, always
It is the research topic being of great significance.
Extinguishing chemical refers to effectively destroying burning condition, make the substance of fire end, extinguishing mechanism is mainly
Cooling, asphyxia, isolation and Chemical Inhibition.Currently, extinguishing chemical can substantially be divided into two major classes: physics according to the difference of extinguishing mechanism
Extinguishing chemical and chemical.Physical extinguishant includes water, foam, carbon dioxide, nitrogen, argon gas and other inert gases, it
In fire extinguishing procedure while reducing combustion mixture temperature, combustible is isolated, to play the role of fire extinguishing in dilution oxygen；
Chemical includes that halon extinguishing agent, dry powder fire extinguishing agent etc. are a variety of, it is the chain reaction by cutting off living radical
And inhibit burning.
Up to the present, water is still most-often used extinguishing chemical, and it is excellent that it has, and source is wide, cheap, fire extinguishing property is strong
Point.But water is also clearly present, be easy to run off the disadvantages of big including mobility.Water-based extinguishing agent is to be increased using water as base-material by addition
Thick dose, initiator, the additives such as antifreeze, change the performance of water, to improve a series of extinguishing chemicals of extinguishing ability.However mesh
There is some shortcomingss for preceding water-based extinguishing agent, and such as applicable fire phases are not comprehensive, fire-fighting efficiency is low, fire re-ignition is high
Deng.Therefore, it is badly in need of the applied widely, high-effect fire-extinguishing of one kind in the market and prevents the fire-extinguishing agent of fire re-ignition.
