The three-component polyurethane injecting paste material performance parameter for the leak stopping of gushing water crack of above four kinds of examples preparation is shown in Table
1。
Each embodiment material result of table 1
Viscosity, required intensity of 1 material of consolidated statement etc. finally have chosen high activity hydrophilic polyether polyalcohol: polyethers N210
=70:30, gained component A viscosity is big, and reaction speed is fast, it is ensured that can penetrate into tiny hole when material slip casting easily
In gap and crack, so that plugging effect is more preferable.In construction, implements to drill in gushing water crack position, pass through two-component grouting pump
By the tri- component pressure injection crack A, B, C, it can react rapidly when the mixing of two components, form a kind of viscosity of the larger liquid.It should
Material can largely absorb moisture, start to foam rapidly, and enter the milky white state of foam at 30 seconds or so, start to coagulate within 70 seconds or so
Glue, one and half or so enter tack-free state, and subsequent polyurethane foam solidification is supported crack.The material has technique
Simply, transporting it is good, it is adaptable, before curing have good mobility, water imbibition is strong, anti-flammability is strong, curing time is fast
The features such as.Gushing water in coal-mine can be successfully managed, and the crack that can be generated to gushing water reinforces.
Material result of the present invention includes:
1, compaction is filled
Polyurethane slurries are in addition to pump pressure, and reaction generates CO after meeting water2, generate very big interior pressure.Both pressure are common
Effect pushes slurry stream dynamic, can not only fill up crack in the rock mass interconnected, and can also by filling less than enclosed type
Minute fissure and hole compacting, play filling compaction to fragmented rock body, increase rock mass natural resiliency modulus, while also mentioning
The high intensity of fragmented rock body.
2, cementation
After roadway grouting, a large amount of active isocyanate end groups contained in performed polymer carry out chain extension, degassing, branch after meeting water
Change and cross-linking reaction, form gelinite not soluble in water.There are a large amount of polar groups, such as urea bond, ehter bond in gel molecular,
There is very strong cementation with fissure-plane.This cementation has highly important work to prevention crack propagation and absciss layer
With.
3, network skeleton acts on
Polyurethane gle body is solidified into hard polyurethane foam, and network-like skeleton structure is formed in country rock body, to improve
The bearing capacity of country rock body, and with good toughness and viscosity, make the coal and rock residual strength with higher after reinforcing.For
Solve the problems, such as that the water drenching of tectonic province breaking surrounding rock and breaking roof all achieve good effect rich in pool burst problem.
4, change rock mass damage machining function
After polyurethane injecting paste material blind, reinforcement material is full of in crack, and there are certain bulbs of pressure, in addition material
Expect the cementation to fissure-plane, the stress of crack end is made significantly to weaken or disappear, so that surrounding rock failure mechanism be forced to be sent out
Raw fundamental shifts: i.e. by being changed into three-dimensional stress constraint in two-dimensional state of stress, increase the strength degree of coal and rock significantly
Add, to improve the ability of country rock body resistance to deformation destruction.
Material advantages of the present invention also reside in:
(1) environmentally friendly and fire-retardant, in underground, coal body itself has the hidden danger of spontaneous combustion, and untreated polyurethane oxygen refers in addition
Number reaches 20%, can also generate the toxic gases such as a large amount of flue dust and CO, HCN when belonging to combustible material, and burning, strong to human body
Health and environment have totally unfavorable influence.For this purpose, the flame retardant property for improving injecting paste material is always a weight of mining safety
Want the hot research topic of project and polyurethane industrial.The approach for improving polyurethane injecting paste material flame retardant property mainly has two
Item: first, introducing the atoms such as halogen, phosphorus, antimony on polyethers or isocyanic acid ester bond, structural fire proofing is obtained；Second, being exactly
The compound of the elements such as halogen, phosphorus is added, i.e. addition fire retardant.And positive high-efficiency low-toxicity is dustless at present or few dirt, low for fire retardant
Smoke direction is developed, and the necessarily choosing that will become polyurethane industries among others with or without the use of halogen containing flame-retardant is reduced；
(2) high activity hydrophilic polyether polyalcohol (EO:PO=85:15), common polyether N210, toluene di-isocyanate(TDI) (-
NCO content is 7%~8%) 0.1% foam stabiliser is added, available optimal adhesion strength is added on this basis
The kaolin of 20wt%, viscoelastic polyurethane knotting strength is up to 1.9MPa or so, and unit intensity compressive strength is up to 2.02MPa/ (g/
cm3), shore hardness is up to 56A；
(3) dihydric alcohol and diamine for being added to low molecular weight further increase the intensity of polymer as chain extender.
(4) it is added to antistatic agent appropriate, organic material is reduced in underground and generates the risk that electrostatic sets off an explosion.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
