Embodiment 1
[0030] Embodiment 1: be used for the preparation method of coal rock crack-pore plugging consolidation quick-setting material, wherein the quality of each component in component A and component B is shown in table 1 and table 2 below respectively, as figure 1 As shown, the specific steps are:
[0031] ①Preparation of component B: Take the required amount of quicklime, dihydrate gypsum, sodium sulfate, sodium lauryl sulfate, and alkaline aqueous solution and add them to beaker A in sequence, stir with a glass rod for 10 minutes, let it stand for later use, and insert a thermometer Observe the temperature change of the solution;
[0032]②Preparation of component A: Take the required number of graphene oxide, expansion agent (bentonite), and thickened aqueous solution (the thickener is xanthan gum) and add them to beaker B in turn, stir with a glass rod for 2 minutes, then add Stir the required amount of cement for 10 minutes, then add the required amount of alum, stir for 2 mi...
Embodiment 2
[0044] Example 2: Weigh 120g of quicklime, 120g of dihydrate gypsum, 5g of sodium lauryl sulfate, 400g of an alkaline aqueous solution with a pH value of 12.4, and add them to beaker A in turn, stir with a glass rod for 10min, and let it stand for later use , and insert a thermometer to observe the temperature change of the solution; weigh the required number of graphene oxide 0.1g, expansion agent (iron powder) 2.5g, thickened aqueous solution (wherein the thickener is peach gum) 200g and add them to beaker B in turn After stirring for 2 minutes with a glass rod, add 100 g of aluminate cement and stir for 10 minutes, add 5 g of bile alum, stir for 2 minutes, and let it stand for later use; when the temperature of the solution in beaker A rises to 40 ° C, put Add the solution in beaker B to beaker A, and stir for 10 minutes to form a paste-like slurry of coal rock cracks-pore plugging consolidation quick-setting material, and record the hydration of the coal rock crack-pore plu...
Embodiment 3
[0046] Example 3: Weigh 120g of quicklime, 120g of dihydrate gypsum, 5g of dihydrate gypsum, 5g of sodium lauryl sulfate, and 400g of alkaline aqueous solution with a pH value of 12.3, and add them to beaker A in turn, stir for 10min with a glass rod, and let stand for later use , and insert a thermometer to observe the temperature change of the solution; Weigh graphene oxide 0.01g, expansion agent (aluminum powder) 2g, thickened aqueous solution (thickener wherein is xanthan gum and peach gum by 1: 1 ratio and mixed) 150g was added to beaker B in sequence, and after stirring for 2 minutes with a glass rod, 75g of sulfoaluminate cement was added and stirred for 10 minutes, and 2g of bile alum was added, stirred for 2 minutes, and left to stand for later use; When the temperature of the solution in A rises to 40°C, add the solution in beaker B to beaker A, and stir for 10 minutes to form a paste-like slurry of coal rock crack-pore plugging and consolidation quick-setting materia...
