Description
Technical field
The invention belongs to coal mine gas plugging material fields, and in particular to a kind of gas discharge in mine hole hole sealing bag blocks
Material and preparation method thereof.
Background technique
Gas accident is one of disaster the most serious in coal mining accident, and the generation of accident is to people's property and life security
Heavy losses are brought, and gas drainage under suction is one of the essential measure for preventing and treating coal mine gas disaster.During gas drainage under suction, watt
The sealing in this extraction hole be the key that guarantee gas drainage under suction everything goes well with your work carry out, the quality of sealing quality, it will directly affect negative
The effect to draw out methane is pressed to occur gap between releasing pipe and hole wall if gas extraction hole sealing effect does not reach requirement,
Making the negative pressure not reached requirement in goaf, during gas drainage under suction, the gap that gas can prolong between extraction hole gushes out or sprays,
Making distinguished and admirable gas in drill site and tunnel is more than limiting concentration, causes serious security risk.
Closure for gas extraction hole, traditional approach include two kinds of method for blocking, and one is plugging material is sufficiently mixed
It closes, then is impregnated with the fabrics such as towel, cotton yarn with mixed raw material, along gas drainage pipe direction, bundle paragraph by paragraph, be then fed into pumping
In discharge hole；Another kind is to twine hole sealing bag with adhesive tape to tie up on gas drainage pipe, is then fed into extraction hole, the later period is again with sealing of hole material
Block unencapsulated gap.There is complicated for operation, low efficiency, local reaction temperature height, sealing of hole effect and pay no attention in both modes
The disadvantages of thinking.
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of gas discharge in mine hole hole sealing bag closure materials

Performed polymer be less prone to cross-linked network, there is preferable flexibility, and be not easy to be oxidized.
The addition of silicate in component A, silicate can absorb the carbon dioxide in ambient enviroment in the presence of water,
The higher silicic acid gel of intensity is formed, when silicic acid molecule has 6 hydrones, there is maximum intensity.On the other hand, silicate
As a kind of fireproof inorganic object, the timely external environment of reaction heat is transmitted in A, B component reaction process, reduces reaction highest
Temperature.
The addition of diglycol and curing agent AQ210 in component A, can rapidly with isocyanide unreacted in B component
Acid group carries out chain extension and cross-linking reaction, can effectively improve the intensity and cohesive force of foam after reaction.
Polytetrahydrofuran ether is reacted with the isocyano in same component first in B component, generates base polyurethane prepolymer for use as, is formed
Backbone with certain molecular weight improves the foam flexibility generated after two component reactions.
Compared with prior art, beneficial effects of the present invention are as follows:
1, A of the present invention, B component good fluidity can be reached inside extraction hole along gas drainage pipe direction；
2, the base polyurethane prepolymer for use as that B component of the present invention is formed, improves intensity, adhesion strength and the stabilization of foam after sealing of hole
Property；
3, non-ignitable silicate is added in component A of the present invention, on the one hand reduces highest internal reaction temperature, on the other hand
The flame retardant property of material is improved, the security performance of sealing material can be effectively improved；
4, chain extender and curing agent are added in component A of the present invention, improves the toughness and rigid nature of foam after reaction, together
When also improve foam for the caking property of hole wall, effectively prevent because the bubble that collapses, contracting bubble, caking property is not strong due to there is showing for gap
As；
5, in component A of the present invention glycerol and OP-10 addition, effectively improve the intersolubility and group of each component in component A
The stability of material is closed, effect is without influence after long term storage；
6, preparation method of the invention and process for using are simple, it is only necessary to which a worker can complete all operationss, significantly
It improves work efficiency while reducing cost of labor.
