Embodiment 1

[0054] (1) 70 grams of aluminum sulfate

[0055] (2) Sodium stearate 20 grams

[0056] (3) Sodium hydroxide (28% aqueous solution) 30 grams

[0057] (4) 1000 grams of water

[0058] Sodium hydroxide aqueous solution (3) is added in water (4) under stirring, then aluminum sulfate (1) is added and dissolved under stirring, then sodium stearate (2) is added in the described solution under stirring to obtain this product Invented water leakage preventer.

[0059] 600 g of water was added to 2.6 kg of commercially available sand-mixed cement (trade name: Katei Cement, manufactured by Tokyo Sun Home KK) and mixed thoroughly, then it was packed into a mold frame and allowed to cure as figure 1 shape.

[0060] Cut the cement container in half ( figure 2 Schematic), the two halves of the container were then joined with a 1 mm thick, 5 mm wide polyester film spacer placed between the two halves with a gap and then reinforced with wire. Water was added to the container and water i...

Embodiment 2

[0063] (1) 80 grams of aluminum ammonium sulfate

[0064] (2) Sodium Oleate 20g

[0065] (3) Sodium hydroxide (28% aqueous solution) 20 grams

[0066] (4) 1000 grams of water

[0067] Add sodium hydroxide aqueous solution (3) into water (4) under stirring, then add aluminum ammonium sulfate (1) under stirring to dissolve, then add sodium oleate (2) into the solution under stirring to obtain the present Invented water leakage preventer.

[0068] Separately, the same container as in Example 1 was produced. 50 grams of the water leakage preventing agent of the present invention were applied to the seams of the container. The container was left for 3 hours and no water leaked through the seams after filling. The container filled with water was left for 3 days and no water leaked from the seams.

[0069] The container which was drained of water and dried at 60° C. for 3 days was treated with the above-mentioned water leakage preventive agent of the present invention. The con...

Embodiment 3

[0070] (1) 33 grams of aluminum sulfate

[0071] (2) Sodium semi-hard tallowate soap 14g

[0072] (3) Cellulose powder 10g

[0073] (4) Zeolite powder 8 grams

[0074] (5) Lithium hydroxide monohydrate 21 grams

[0075] (6) 1000 grams of water

[0076] Add lithium hydroxide monohydrate (5) into water (6) under stirring, then add semi-hard sodium tallowate soap (2), cellulose powder (3) and zeolite powder (4) into the above solution under stirring Disperse in the solution, and then add aluminum sulfate (1) into the solution under stirring to obtain the water leakage preventive agent of the present invention.

[0077] Separately, the same container as in Example 1 was produced.

[0078] 50 grams of the water leakage preventing agent of the present invention were applied to the seams of the container. The container was left for 3 hours and no water leaked through the seams after it was filled with water. The container filled with water was left for 3 days and no water leak...

Abstract

The present invention provides a water seepage preventive agent with excellent waterproof performance, which can seal leaks by a simple method without damaging the surface of buildings. The water leakage preventing agent of the present invention includes (a) a surfactant, (b) an aluminum compound, and (c) an alkaline substance, and if necessary, water.

Description

technical field [0001] The present invention relates to a water leakage preventive agent having excellent waterproof leakage performance and a method for waterproof leakage, more particularly, the present invention relates to a water leakage preventive agent capable of entering water leakage cracks or channels and filling gaps to prevent water intrusion; And relates to a method for preventing water leakage by applying a water leakage preventing agent on the roof, floor or wall of a building, or spraying the water leakage preventing agent to the roof, floor or wall of a building to achieve waterproofing method of leakage. Background technique [0002] To prevent water seepage in roofs, floors or walls, sealants must be applied or filled at leaks such as holes, cracks and gaps. If the location of the leak cannot be determined, a total repair such as re-roofing, replacement of waterproofing, and complete coating or re-tiling of the walls will be required. That said, simple ma...
