preparation example Construction

[0034] A preparation method of a high-strength anti-seepage leakage repairing material, comprising the steps of:

[0035] Put half of the total weight of cement and half of the total weight of quartz sand into the mixer and stir and mix for 10 minutes to prepare the main material mixture, wherein the stirring speed is 20r / min;

[0036] Swelling agent, dispersible latex powder, lithium chloride, calcium chloride, calcium stearate, hydroxypropyl methylcellulose, sodium hexametaphosphate, construction polypropylene fiber and water reducer are added in turn to the main material mixture and stirred and mixed 10min, make auxiliary material mixture, wherein stirring speed is 25r / min;

[0037] Add the remaining cement and quartz sand to the auxiliary material mixture and stir and mix for 20 minutes (stirring speed is 30r / min) to prepare a high-strength anti-seepage and leakage repairing material.

[0038] Example 1 to Example 5 High-strength anti-seepage and leak-remediation material...

Embodiment 3

[0048] The performance of the high-strength anti-seepage and leak-remediation material prepared in Example 3 is the best. Taking the high-strength anti-seepage and leak-remediation material prepared in Example 3 as an example, the repair work of waterproofing and leak-proofing at the pipe root is carried out.

[0049] Clean and level the base surface to be constructed, and remove floating ash and oil stains, take high-strength anti-seepage leakage repairing material and pure water with a volume ratio of 1:0.4, pour the high-strength anti-seepage leakage repairing material into pure water and stir until there is no agglomeration, and obtain high-strength anti-seepage leakage repairing material Anti-seepage leakage repair slurry.

[0050] According to the conventional treatment method, remove the groove at the position to be repaired, fill the groove with high-strength anti-seepage and leakage repairing slurry in a diagonal direction or circular rotation, and use a caulking knife...

Abstract

The invention relates to a high-strength anti-permeability leak-repairing material and a preparation method thereof. The high-strength anti-permeability leak-repairing material comprises the followingcomponents in parts by weight: 710-800 parts of cement, 140-160 parts of quartz sand, 20-30 parts of a swelling agent, 35-45 parts of dispersing emulsion powder, 4-6 parts of lithium chloride, 5-10 parts of calcium chloride, 4-6 parts of calcium stearate, 4-6 parts of hydroxypropyl methyl cellulose, 2-3 parts of a water reducing agent, 4-6 parts of sodium hexametaphosphate and 4-6 parts of construction polypropylene fiber. The high-strength anti-permeability leak-repairing material is prepared from the components as follows: stirring and mixing a half of cement and a half of quartz sand for 10min, thereby acquiring a main material mixture; successively adding the other components except for the cement and quartz sand into the main material mixture, stirring and mixing for 10min, thereby acquiring an auxiliary material mixture; adding the residual cement and quartz sand into the auxiliary material mixture, stirring and mixing for 20min, thereby acquiring the high-strength anti-permeability leak-repairing material. The high-strength anti-permeability leak-repairing material prepared according to the formula and method has the characteristics of excellent cracking resistance, high toughness and excellent adhesiveness.

Description

technical field [0001] The invention relates to the field of anti-seepage and anti-leakage at corner positions, in particular to a high-strength anti-seepage and leak-remediation material and a preparation method thereof. Background technique [0002] In the process of building construction, the structure of pipe roots, floor drains, yin and yang corners and other parts is relatively complex. These positions are usually weak parts and are prone to cracking due to environmental and other factors. The anti-seepage reinforcement of corner positions is particularly important. [0003] Conventional waterproof and anti-seepage materials are shown in the Chinese patent application publication number CN102167547A, which discloses a permeable crystalline waterproof material that can quickly repair cracks. The material includes cement, expansion agent, quartz sand, mineral additives, Water agent, retarder, crystal settler, complexing agent, calcium ion compensator and crystal growth a...
