Problems solved by technology

[0002] Buildings are prone to water leakage from roofs, roofs, interior walls, exterior walls, toilets, basements, factory sewage pools, reservoirs, etc. in use. In order to prevent building water leakage from affecting the service life of buildings, it is necessary to Waterproofing treatment, the traditional waterproofing treatment includes covered waterproofing such as modified asphalt waterproofing membrane, etc. The disadvantage is that the waterproofing material is covered on the building after construction. Short, generally need to be replaced in about two or three years; there are also polyurethane waterproof coatings, which are generally diluted with organic solvents such as toluene and xylene when using such coatings, which contain volatile toxic gases and are not easy to remove. Construction personnel have strict requirements; in addition, there are polymer cement-based waterproof coatings, which generally have higher costs

Embodiment 1

[0014] Liquid water-based waterproofing agent, its components and the mass-number ratio between each component are:

[0015] Aluminum silicate 2, aluminum potassium sulfate 2, aluminum sulfate 3, sodium hydroxide 1, water 72.

[0016] Preparation:

[0017] Weigh each component according to the proportion of the formula, then add aluminum silicate, expansion agent, and aluminum sulfate into water successively, stir in the reaction kettle for 2 hours, then add sodium hydroxide, and mix thoroughly for 7 hours to prepare a mixed solution. Then filter to remove impurities in the solution.

[0018] How to use: First, pre-treat the base surface of the object to be applied, remove oil stains and other impurities on the base surface, keep the base surface dry, and then apply this liquid water-based waterproofing agent to the concrete base surface by brushing or spraying. In order to enhance the waterproof effect, it can be sprayed several times after each brush is dry.

Embodiment 2

[0020] Liquid water-based waterproofing agent, its components and the mass-number ratio between each component are:

[0021] Aluminum silicate 3.5, aluminum potassium sulfate 2.5, aluminum sulfate 3.5, sodium hydroxide 9, water 81.

[0022] Preparation:

[0023] Weigh each component according to the proportion of the formula, then add aluminum silicate, expansion agent, and aluminum sulfate into water successively, stir in the reaction kettle for 2 hours, then add sodium hydroxide, and mix thoroughly for 7 hours to prepare a mixed solution. Then filter to remove impurities in the solution.

[0024] How to use: First, pre-treat the base surface of the object to be applied, remove oil stains and other impurities on the base surface, keep the base surface dry, and then apply this liquid water-based waterproofing agent to the concrete base surface by brushing or spraying. In order to enhance the waterproof effect, it can be sprayed several times after each brush is dry.

Embodiment 3

[0026] Liquid water-based waterproofing agent, its components and the mass-number ratio between each component are:

[0027] Aluminum silicate 5, ferric chloride 3, aluminum sulfate 4, sodium hydroxide 18, water 90.

[0028] Preparation:

[0029] Weigh each component according to the proportion of the formula, then add aluminum silicate, expansion agent, and aluminum sulfate into water successively, stir in the reaction kettle for 2 hours, then add sodium hydroxide, and mix thoroughly for 7 hours to prepare a mixed solution. Then filter to remove impurities in the solution.

[0030] How to use: First, pre-treat the base surface of the object to be applied, remove oil stains and other impurities on the base surface, keep the base surface dry, and then apply this liquid water-based waterproofing agent to the concrete base surface by brushing or spraying. In order to enhance the waterproof effect, it can be sprayed several times after each brush is dry.
