Abstract
The present invention discloses a high water content fire extinguishing filling material, which is prepared from the following raw materials, by weight: 40-50% of calcium sulfoaluminate cement, 30-40% of lime CaO, and 20-30% of bentonite. The preparation method comprises: processing calcium sulfoaluminate cement, lime and bentonite into solid fine material with a particle size of 200 mesh and a screen residue of not more than 10%, and uniformly mixing the materials according to the ratio to obtain the high water content fire extinguishing filling material. During use, 3 parts of water and 1 parts of the high water content fire extinguishing filling material are uniformly stirred, and blended into a high water content flowing slurry with a mass concentration of 25% and a volume water content of more than 85%, and the obtained slurry is poured into a region requiring fire extinguishing, and can be solidified after 30 min so as to provide a good blocking barrier effect and achieve a fire extinguishing purposes. The high water content fire extinguishing filling material has characteristics of good fluidity, easy slurry preparation, easy pumping, and low cost.
Description
Technical field
The invention belongs to material of construction and mining material technical field, particularly relate to a kind of high moisture fire extinguishing packing material and preparation and using method.
Background technology
Mine fire is one of colliery 5 big spontaneous combustion disasters, the generation of every fire, gently then influence is produced, and weight person may burn coal resources and pit gear, then may ignite gas and dust explosion or fiery cigarette of even more serious person poisons mine, leads to the great serious accident of loss of life and personal injury.
Prevent that a kind of thinking that mine fire spreads expansion from being that shutoff is carried out in tunnel or worked-out section, its mainly act on be prevent from leaking out, secluding air.
The foaming and intumescing packing material is the plugging material of using always, but its curing speed is slow, and the bubble of generation is easy to run off.Silicate cement is abundant as the composition of foaming and intumescing packing material, and it needs other more auxiliary materials, and the curing speed speed is subjected to auxiliary material, temperature effect bigger.
The space in tunnel or worked-out section is bigger, simultaneously, for the necessary security surplus, needs a large amount of packing materials during shutoff, and therefore a large amount of uses must bring huge cost consumption.
Therefore, researching and developing a kind of efficient, cheap fire extinguishing packing material is of great practical significance for Coal Production.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, provides a kind of high moisture
The fire extinguishing packing material, its price cheapness is used efficiently, and the shutoff curing speed is fast, and the present invention provides preparation and the using method of this packing material simultaneously.
Technical scheme of the present invention is as follows:
A kind of high water fire extinguishing packing material is to be made by following raw materials by weight percent: aluminosulfate cement: 40-50%; Lime CaO:30-40%; Wilkinite: 20-30%.
Preferably, the weight percent of high each raw material of water fire extinguishing packing material is: aluminosulfate cement: 50%; Lime CaO:30%; Wilkinite: 20%.
The preparation method of the high water of the present invention fire extinguishing packing material, is processed into 200 mesh screen residues with aluminosulfate cement, lime and wilkinite and is not more than 10% solid segmentation material ⑴; ⑵, mix by following weight percent then: aluminosulfate cement: 40-50%, lime CaO:30-40%, wilkinite: 20-30%.
The using method of the high water fire extinguishing of the present invention packing material, 3 parts of water and 1 high water fire extinguishing packing material material are stirred, be modulated into mass concentration 25%, volumetric(al) moisture content is at the high moisture mobile slurries more than 85%, then slurries are circulated into the location that needs fire extinguishing, can be fixed after 30 minutes, play good shutoff and intercept, arrive the fire extinguishing purpose.
Excellent effect of the present invention:
1, high water fire extinguishing packing material good fluidity of the present invention, slurrying and pumping are easy, are convenient to carry, and can not stop up transfer line.
2, about 600 yuan/ton of the prices of aluminosulfate cement on the market, the price of lime is about 300 yuan/ton, 200 yuan/ton of bentonitic prices, therefore the cost by the high water fire extinguishing of this kind packing material of above material preparation is cheap.
