preparation example Construction

[0034] Such as figure 1 Shown, the preparation method of the nondestructive plugging agent based on inorganic silicate comprises the steps:

[0035] Step 1: Make component A, turn on the mixer, add sodium silicate solution, surfactant, and complexing agent to the mixer in sequence, and stir evenly for a period of time to obtain component A;

[0036] Step 2, making component B, adding calcium salt and water in turn to another blender or the mixer in step 1 that has been rinsed, and stirring evenly for a period of time to obtain component B.

[0037] Preferably, in the above-mentioned preparation method of non-destructive lost circulation plugging agent based on inorganic silicate, it also includes: step 3, distributing component A in step 1 and component B in step 2 into storage.

[0038] figure 2 It is a flowchart of the construction method of the non-destructive plugging agent based on inorganic silicate of the present invention;

[0039] Such as figure 2 As shown, the ...

Embodiment 1

[0044] Embodiment 1: (A component: sodium silicate solution 90%, sodium dodecylbenzene sulfonate 1%, EDTA9%; B component: concentration is the calcium nitrate solution 100% of 5%)

[0045] Preparation of component A: measure by weight, take 90kg of sodium silicate solution, 1kg of sodium dodecylbenzene sulfonate, and 9kg of EDTA, and slowly add them to the started mixer in turn. After all the materials are added, stir evenly for 30 Minutes, shut down, put into warehouse, obtain about 100kg of A component.

[0046] Preparation of component B: measure by weight, take 5kg of calcium nitrate and 95kg of water, and slowly add them into the started mixer in turn. After all the materials are added, stir evenly for 30 minutes, stop the machine, put them into the warehouse, and get B The components are about 100kg.

[0047]Then, use a batch knife or a wallpaper knife to remove the movable spoils in the joints of the floor tiles, clean up the ground garbage, and then block the floor dr...

Embodiment 2

[0048] Embodiment 2: (A component: potassium silicate solution 88%, sodium dodecylbenzenesulfonate 1%, EDTA-4Na11%; B component: concentration is 8% calcium chloride solution 100%)

[0049] Preparation of component A: measure by weight, take 88kg of potassium silicate solution, 1kg of sodium dodecylbenzenesulfonate, and 11kg of EDTA-4Na, and slowly add them to the started mixer in sequence. Stir for 1 hour, stop the machine, put it into storage, and obtain about 100kg of component A.

[0050] Preparation of component B: measure by weight, take 8kg of calcium chloride and 92kg of water, and slowly add them into the started mixer in turn. After all the materials are added, stir evenly for 1 hour, stop the machine, put them into the warehouse, and get B The components are about 100kg.

[0051] Then, use a batch knife or a wallpaper knife to remove the movable spoils in the joints of the floor tiles, clean up the ground garbage, and then block the floor drain; take 5kg of compone...

Abstract

The invention relates to the technical field of building materials and discloses a lossless plugging agent based on inorganic silicate and preparation and construction methods of the lossless pluggingagent. The lossless plugging agent comprises an A composition and a B composition, wherein the A composition comprises the components, by weight, of 80%-95% of silicate solution, 0.5%-1.5% of surfactant and 3.5%-19.5% of complexing agent, and the B composition is 100% of calcium solution. The problems that the silicate and the calcium solution react instantaneously and rapidly, the gel is not uniform due to the fact that the gel is only generated in the position of the bonding interface, the strength is low and the service life is short are solved by the aid of the compounding of the A composition and the B composition; the complexing agent is added into the A composition so that the silicate can generate a metal complex, the mobility is increased, the B composition is poured into the A composition and mixed uniformly, the calcium solution cannot react with the silicate immediately under the action of the complexing agent to generate calcium silicate hydrate, at this moment the mixedliquid is still a uniform solution in a flowing state, the mixed liquid gradually penetrates into a water leakage seam below a tile, and a leakage water channel is plugged permanently.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a non-destructive plugging agent based on inorganic silicate and its preparation and construction methods. Background technique [0002] Bathrooms and kitchens are areas with a high incidence of water leakage in houses. The main reasons are: large water consumption, easy to accumulate water, and the acidity and alkalinity of daily chemicals such as detergents will accelerate the corrosion and aging of the waterproof layer. The structure is complex and there are many pipes. Construction is very difficult. The traditional treatment method can only be re-waterproofed as a whole. The specific method is to remove the decorations such as tiles on the surface first to expose the base surface. After the base surface is treated, the whole body is brushed with waterproof slurry. After curing, do a closed water test, and then restore the surface after passing the test. Tiles and...
