Description
Technical field
The present invention relates to fireproofing extinguishing materials technical fields, and in particular to a kind of coal mine composite fire extinguishing material and its preparation side
Method.
Background technology
The coal mine of pit mining is generally subject to production technique limitation, and more coal can be all left in goaf, is being supplied
Oxygen and accumulation of heat environment are suitable in the case of, through spontaneous combustionof coal will occur after a period of time.Underground coal mine coal spontaneous combustion is coal
One of five big disaster of mine.China is big coal country, has 50% coal mine to have coal spontaneous combustion threat at present, and with China Midwest
It is more serious that new lignite coal field development and old mine enter deep mining, the threat of coal spontaneous combustion.The original substantially of coal spontaneous combustion fire
Reason also obeys combustion triangle shape and quadrangle.But the condition and method of its forming process, the environment of spontaneous combustion, fire extinguishing, there is oneself
The characteristics of.There are one long or short occurrence and development processes for coal spontaneous combustion fire, and because of coal and rock mass poor thermal conductivity, are not easy early
It was found that.Most burning things which may cause a fire disaster are hidden, are frequently experienced in people and are difficult in the goaf entered or inaccessiable coal column, put out in time compared with
It is difficult.And fire once being formed, and the oncoming force is swift and violent.Even working face is forced to stop adopting, several ten million so that more than one hundred million members mechanical equipment envelope
It is damaged, has opened up, to prepare the coal amount frozen in flame range, directly affect mine normal production and connecting.Meanwhile coal mine
Underground belongs to hemi-closure space, and fire is occurring, generating a large amount of toxic and harmful gas (such as CO, CO2, SO2) and toxic during development
Flue dust seriously threatens miner's life security.And water vapour, water-gas generated when putting out a fire etc. can only be moved to a direction, be rescued
The working space of calamity personnel is small, and the room for maneuver is small, and prodigious threat is brought to disaster relief personnel.
Common extinguishing chemical has water, foam, alkyl halide, carbon dioxide etc..The gas such as alkyl halide, carbon dioxide, inert gas
Body extinguishing chemical higher price, and be difficult in open space to play its fire-fighting efficiency；Dry powder fire extinguishing agent fire-fighting efficiency is higher, fire extinguishing
The effect that the fast of speed but when dry-chemical fire extinguishing small to the cooling effect of burning do not have covering and prevent burning from evaporating substantially, dump
Surface easily causes resume combustion, does not play a role substantially inside dump；Fire foam is applied to combustible liquid fire fire-fighting efficiency
Height, the fast of blow-off velocity but coal spontaneous combustion fire efficiency is low, dosage is big, uneconomical for putting out a fire to save life and property.
Therefore, Safety of Coal Mine Production is badly in need of highly effective flame-retardant, quick extinguishing and the new material for being not easy resume combustion.
Invention content
In view of this, the present invention provide it is a kind of can highly effective flame-retardant, quick extinguishing and be not easy the coal mine of resume combustion and gone out with compound
Fiery material, and the preparation method for being used to prepare this material is provided, it is easy to operate.
Coal mine provided by the invention composite fire extinguishing material, the fire extinguishing material weight percent includes following component：
Sandy soil 12-15%, vermiculite 5-7%, pyrophillite 3.2-3.5%, bentonite 2.7-3.5%, nano silicon dioxide 1.7-2.0%,

Further, the fire extinguishing material weight percent includes following component：Sandy soil 13%, vermiculite 6%, pyrophillite
3.3%, bentonite 3.2%, nano silicon dioxide 1.8%, sodium carboxymethylcellulose 1.3%, hydroxyethyl cellulose 0.5%, silicon
Hydrochlorate mixture 1.2%, melamine cyanurate 0.6%, phosphoric acid 0.4%, sodium alginate 0.2%, Tween-80 0.2%,
Polyvinyl butyral 0.2%, chitosan 0.1% and water 68.0%；
Further, the silicate mixture is 0.5-0.6 in mass ratio by sodium metasilicate and lithium metasilicate:2.0 mixing compositions；
Further, the sandy soil, vermiculite, pyrophillite and bentonitic grain size are less than 120 μm.
The invention also discloses a kind of methods preparing coal mine composite fire extinguishing material, include the following steps：First by carboxylic first
Base sodium cellulosate, hydroxyethyl cellulose, silicate mixture, melamine cyanurate, sodium alginate, polyvinyl alcohol contracting fourth
The water of aldehyde, chitosan and 3/4 volume is stirred 10-15min, and sandy soil, vermiculite, pyrophillite and bentonite is added thereto later
It is sufficiently stirred 15-20min, adds Tween-80, nano silicon dioxide, phosphoric acid and remaining water, 30min is mixed.
Beneficial effects of the present invention：
The present invention is mixed using the component of excellent, the less toxic evil of multiple performance according to certain content, can be given full play to
Highly effective flame-retardant, quick extinguishing and the coal mine composite fire extinguishing material for being not easy resume combustion is made in synergistic effect between each raw material component,
Composite fire extinguishing material produced by the present invention is ejected on the coal of spontaneous combustion, can quickly be formed on coal can be coated on coal
On the multilayered structures such as sandy soil layer, non-combustible film layer and porous foam coke layer, so as to play the work(such as heat-insulated, oxygen barrier, suppression cigarette
Effect, and play support and dispersion gel effect and the raw material components such as vermiculite, bentonite etc. with water swellability, it can be with
Its own excellent water swellability is played, to which the water adsorbed using it pointedly carries out fast cooling to coal, is made
Burning stops.Wherein, sandy soil itself are non-ignitable, and sandy soil layer can be formed by being coated to after injection on coal；Silicate mixture and original
Can dissociate gel in water after the effects that acidic materials such as phosphoric acid in material, and nano silicon dioxide etc. can increase the bonding of gel
Effect accelerates the consolidation rate of gel, gel layer is enable preferably to be attached on coal, to the quick self-drying shape on coal
At non-combustible film layer；The collaborations such as sodium carboxymethylcellulose, hydroxyethyl cellulose, chitosan, phosphoric acid, melamine cyanurate can
The high temperature generated using spontaneous combustionof coal forms porous foam coke layer on coal surface.
Composite fire extinguishing material produced by the present invention finally can by coal surface formed multilayered structure, to play every
Hot, oxygen barrier, suppression cigarette and other effects, and can targetedly cooling down to coal, so reach highly effective flame-retardant, quick extinguishing effect
Fruit provides the flame retardant property of material significantly.Meanwhile preparation process of the present invention is easy, is suitable for industrialization promotion and production is answered
With.
Specific implementation mode
