Description
Technical field
The present invention relates to a kind of micro-nano capsule extinguishing chemical, and in particular to coating, rubber slab field specially go out electric information fire
A kind of micro-nano fire extinguishing capsule and preparation method.
Background technology
The fire moment threaten country and people the securities of the lives and property, fire again often because live combustible not
Together, the complicated multifactor fire of a condition of a fire is developed into by single cause.
Extinguishing chemical is to refer to effectively destroy burning condition in combustion zone, reaches the thing for resisting burning or extinction
Matter.Extinguishing chemical species is more such as, water-based extinguishing agent, gas extinguishing agent, fire foam, powder extinguishing agent etc..
Although powder extinguishing agent low cost, simple production process, dust pollution is seriously to human body and one in fire extinguishing procedure
A little goods and materials have certain infringement, also without cooling and usage amount ratio when effect and the fire extinguishing of anti-resume combustion as gas extinguishing agent
It is larger.
Fire foam is mainly used in putting out non-water-soluble liquid fire, and mainly fire brigade is using.
Although water-based extinguishing agent fire extinguishing effectiveness is higher, blow-off velocity is fast, is not easy resume combustion, there is also for being not used to
Electrical fire is puted out a fire to save life and property.
So a storage of research and development is convenient, is had using the high appliance fire extinguishing chemical that specially goes out of simple, safety, fire extinguishing effectiveness
Important meaning.
For problem above, the invention provides a kind of micro-nano fire extinguishing capsule and preparation method, with gas extinguishing agent and
Microcapsule coated material is main material, controls high pressure production equipment using hyundai electronicses, solves existing all kinds of extinguishing chemicals and using
In run into electric information fire pollution or damage problem.

During sparging carbon dioxide so that ambient temperature substantially reduces, and the condensate moisture in air, turns into extremely dense water smoke, to high
It is serious caused by expensive electronic equipment to be stained, carbon dioxide and carbonic acid are dissolved in water, in computer room, communications equipment room
Integrated stamen piece, circuit have considerable influence, and can make electric equipment surface produce accumulation of static electricity.The present invention have to protection without
Mansion is lost, and certain protective effect is played for valuable, accurate instrument.And the present invention do not decompose at normal temperatures, be non-hygroscopic,
Do not lump.It is easy to deposit for a long time, and noresidue after fire extinguishing, it is of the invention in addition that also there is good mobility, dispersivity and electricity
Insulating properties, when a fire, the present invention will not cause the short circuit of electric equipment, and the generation of fire fighter's electric shock accidents.
2nd, can be in the non-renewable resources such as cultural heritage, finance data place, the collection in such as national, provincial library, archives
Treasure storehouse in storehouse, museum；The showroom of one-level paper thin,tough silk matter historical relic；The archive office of financial department, bill room, important money
Expect room and press center；Between the expensive facility in larger medical place etc..Water mists also cause while fire extinguishing to protection
Irremediable loss.Historical relic legacy is therefore a kind of single, non-renewable resource applies the present invention to go out in selection
During main material of being put out a fire in fiery system, it can accomplish that good extinguishing effect, blow-off velocity are fast, not have corrosion to historical relic legacy and destroy, have
Preserved beneficial to the long-term safety of historical relic.The present invention is a kind of new production for being different from common dry powder, foam, gas extinguishing agent completely
Product, through national departments concerned detection and it is substantial amounts of it is demonstrated experimentally that the extinguishing chemical it is corrosion-free to historical relic legacy, without destroy, without resume combustion
Deng effect.

Specifically：
The present invention relates to a kind of micro-nano capsule extinguishing chemical, and in particular to coating, rubber slab field specially go out electric information fire
A kind of micro-nano fire extinguishing capsule and preparation method.
Fluorine ion in the fire extinguishing agent molecule that micro-nano fire extinguishing capsule of the present invention contains contributes to the heat of extinguishing chemical
Stability and chemical inertness, bromide ion are then active ingredient of the extinguishing chemical in fire extinguishing procedure.The fire-fighting principle of extinguishing chemical, mainly
It is that bromide ion destruction fuel produces hydrionic chain chemical reaction in combustion, interrupts burning and reach the mesh of fire extinguishing
, by suppressing the chemical reaction process of burning, make flameout, effect is by the activity in combustion chain reaction of taking away
For material come what is completed, this process is referred to as chain breaking process and process of inhibition, similar to powder extinguishing agent effect.And have simultaneously
The physical action of cooling and the cooling of water system and fire foam.Suitable for put out a fire to save life and property various inflammable, combustible liquid fires and electrically
Equipment fire.
Mainly put out a fire in numerous extinguishing chemicals by two ways, first, by starvation come the physics side of fire smothering
Formula.Second, the chemical mode for making caused free radical be far smaller than the free radical to burn by cutting off pyric chain.Capsule of the present invention
Core extinguishing chemical unit volume fire-fighting efficiency is 1.5 times of other species extinguishing chemicals, and capsule core extinguishing chemical of the present invention contains in addition
There is 40% physics fire-extinguishing function concurrently, 60% is chemical mode fire extinguishing, is the optimal combination in extinguishing chemical, therefore in all extinguishing chemicals
Extinguishing effect be best.

One or more in trifluoro propane, HFC-236fa, heptafluoro-propane, IG541.Above gas extinguishing agent is equal in fire extinguishing procedure
Noresidue is produced, and any physics and damage chemically will not be produced to the electrical and electronic component, antiques, ancient books of scene of fire
It is bad.
Covering material is methyl methacrylate, Methyl Methacrylate, 2- methyl -2- methyl acrylates, isobutene
Sour methyl esters, methyl lose the one or more in resin acid methyl esters, methyl methacrylate (MMA), Methyl metacrylate 99.It is more than use
The microcapsules with polymeric shell wall can by liquid or gas entrapment, seal up for safekeeping and turn into a kind of solia particle in microencapsulation
Product.So that gaseous state or the extinguishing chemical of liquid form the solid-state for being easier to store and carrying.
Organic silicone oil is hydrophobic type organic silicone oil, and hydrophobic type organic silicone oil can make have preferably flowing between microcapsules
Property, prevent from luming.
Nano-scale white carbon black is gas-phase silica of the diameter in 50-100nm, the sky that white carbon can be filled up between microcapsules
Gap reduces the friction between microcapsules, prevents microcapsules rupture.
