Description
Technical field
The invention belongs to coal mine fireproofing extinguishing materials technical field, relate to a kind of mining high intensity height water pluralgel and prevent
Fire extinguishing material and preparation method thereof.
Background technology
At present, safety of coal mines situation is the most effectively contained, particularly serious disaster accident happens occasionally.Coal-mine fire is main
Being that coal spontaneous is got angry, owing to air leaks into loose coal, coal molecular surface active structure contacts with oxygen in air, sends out
Raw physical absorption, chemisorbed and chemical reaction, release heat simultaneously, under certain accumulation of heat environment, coal body constantly aoxidizes,
Heat release, intensification, when coal temperature exceedes its critical temperature, continue to heat up, reach ignition point, ultimately result in coal body burning
Cause coal-mine fire.Coal body spontaneous combustion is the exothermic result of coal oxidation, and coal oxidation produces heat, heat radiation of being leaked out
With thermal pressure drive, after various factors coupling influence, coal temperature changes, produced by coal oxidation heat diffusion and
Accumulation is considered again the process of a heat transmission.
Coal bed fire is different from other type of fire, has the feature that himself is intrinsic, such as: burning things which may cause a fire disaster point is hidden, generally
Position relatively is higher, is spatially distributed；Loose coal recovery electric heating system is good, and heat is difficult to scatter and disappear；Can low temperature oxygen deprivation aoxidize, and
The highest response speed of temperature is the fastest, and thermal discharge is the most；Being produced gas hot fluid circulation by the temperature difference, spontaneous combustion convection current is from oxygen supply etc..
According to the feature of above spontaneous combustion of coal seam, spontaneous combustion of coal seam preventing and extinguishing fire technology should have features: reduces coal body internal temperature；
Improve reaction activity；Reduce or completely cut off the oxygen content flowing through loose coal；Temperature tolerance is good, is not likely to produce high temperature gas flow and adds
The characteristics such as heat loose coal around.Current water filling, be in the milk, note retardant, note noble gas etc. only have one therein or
Two kinds of characteristics, therefore there is when putting out coal bed fire certain limitation.
For technology such as preventing and treating spontaneous combustionof coal, domestic and international widely used grouting, gel-filled, note noble gases.Wherein technique of gel extinguishing fires
Technology has the more comprehensive overall characteristic of ratio, and before colloid plastic, the aqueous solution of each component has good mobility, it is simple to
The big flow of pipe network, carrying at a distance, before each component mixing plastic, the pressure injection that is in a liquid state enters portion in loose high-temperature coal body,
Occurring gelation to lose flowability within a certain period of time, colloid can rest on eminence in loose coal, wraps up coal body,
Absorbing and cooling temperature, blocks the passage that leaks out, and reduces the activity of coal surface molecule, improves reaction activity, hinders gas the most right
Stream, isolation coal, oxygen contact, colloid also has preferable heat-resisting quantity, will not produce a large amount of high-temperature steam, can reduce water
The danger of gas explosion, reduces developing fire speed.When utilizing colloidal materials preventing and treating nature of coal seam fire, it is possible to break simultaneously
There are essential three conditions in bad coal spontaneous combustion, has higher fire-fighting efficiency, and the success rate stamped out a fire is higher.
Gel preventing and extinguishing fire technology of the prior art exist subject matter be relatively costly, may produce toxic and harmful,
Gel formation time is uncontrollable, gel formation effect is bad, solid water is poor, narrow application range etc..
Summary of the invention
It is an object of the invention to provide a kind of low cost, intensity is big, viscosity is high, good stability, be widely used, nontoxic nothing
The mining high intensity height water pluralgel fireproofing extinguishing materials of evil, solves problems of the prior art.
It is a further object of the present invention to provide the preparation method of above-mentioned fire extinguishing material.
The technical solution adopted in the present invention is, a kind of mining high intensity height water pluralgel fireproofing extinguishing materials, by following former
Expect according to mass fraction than composition:
Sulphoaluminate cement clinker 10～20 parts, Calx 2～3 parts, waterglass 4～5 parts, water 200～250 parts.
Another technical scheme of the present invention is, the preparation of a kind of mining high intensity height water pluralgel fireproofing extinguishing materials
Method, specifically follows the steps below: according to mass fraction ratio, weighs sulphoaluminate cement clinker 10～20 parts, stone
Ash 2～3 parts, waterglass 4～5 parts, water 200～250 parts；Sulphoaluminate cement clinker is mixed with water and is sufficiently stirred for,
Waterglass mixes with water and is sufficiently stirred for, and after stirring, is sufficiently mixed by two kinds of serosity and continues stirring, with often
The speed of minutes 60～90 turns stirs 3～5 minutes, adds Calx and continues stirring 3-5 minute, to obtain final product.
The invention has the beneficial effects as follows owing to including sulphoaluminate cement clinker, Calx, waterglass, first by aluminium sulfate
Clinker and waterglass are sufficiently mixed with water respectively, then by after both the above mixed serum mix and blend, add specific
After the Calx mixing of ratio, stirring, obtain this product.This product cost is low, intensity big, and viscosity is high, good stability, tool
There is the characteristic that mining closure fireproofing extinguishing materials requirement is possessed.
Detailed description of the invention
