Description

Technical Field

[0001] The invention relates to the technical field of building maintenance, in particular to a method for repairing bathroom leaks. Background Art

[0002] At present, the common method for repairing leaks in bathrooms is to tear down all the tiles and re-waterproof them. However, there are the following shortcomings in tearing down the tiles and re-waterproofing them:

[0003] (1) It is time-consuming to demolish and redo the bathroom, which normally takes about 7-15 days. It also produces a lot of construction waste and pollutes the environment. The construction cost is high and will affect the owner's use.

[0004] (2) If the bathroom is demolished and rebuilt, it will only require a new layer of waterproofing on the bottom layer of the bathroom. If there is no water seepage at the bottom of the bathroom, then after demolishing it, you will only need to re-build a layer of waterproofing on the place where there is no leakage. This will be a waste of effort.

[0005] (3) After the waterproof layer in the bathroom is removed and redone, and the tiles are laid, the mortar layer under the tiles still has no waterproof layer. When water is used later, the water will reach the mortar layer from the tile joints. As the moisture in the mortar layer increases, the water will be under pressure, and the water under pressure will flow upwards. As long as there are gaps or transmission media at high places, it will cause water leakage to other places through the media.

[0006] (4) If removing it can completely solve the leakage problem, then it can be completely solved when the new house is being renovated, and there will be no leakage later.

[0007] (5) As most of the materials on the market are highly elastic, flexible, and general-purpose waterproof materials, most of these materials are not resistant to water blisters. Bathrooms are exposed to water blisters every day, so many owners tear down and redo waterproofing without solving the problem. After a few years, it will cause leakage again. Another reason why tearing down and redoing may not be done well is that after tearing down, all the leaks are not repaired. Therefore, it will leak again right after the waterproofing is done. This is also very common. Summary of the invention

[0008] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for quickly and thoroughly preventing bathroom leakage.

[0009] To achieve the above purpose, the technical solution adopted in the present invention is as follows:

[0041] (1) Short time consumption, no construction waste, no impact on the owner’s use, and low cost.

[0042] (2) The problem of water leakage caused by water accumulation in the caisson can be completely solved because the drainage system will not be permanently blocked.

[0043] (3) You don’t need to discard the tiles, you can build a thick waterproof layer on the bottom of the caisson. Regardless of whether the bottom of the bathroom is leaking or not, you have added a layer of insurance.

[0044] (4) It can completely solve the waterproofing problem of the mortar layer under the tile joints, thus effectively blocking the problem of water transmission medium. Without a medium for water transmission, the daily domestic water can only flow away through the floor drain pipe.

[0045] (5) It can completely solve other water source problems that are prone to water leakage, such as the triangular valve interface, shower pipe interface, floor drain, between the squat toilet tank drain pipe and the squat toilet connection port, and between the toilet bottom pad and the pipe port.

[0046] (6) It can completely solve the problem of water leakage in tile joints. DETAILED DESCRIPTION

[0047] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples. The experimental methods in the following examples without specifying specific conditions are carried out according to conventional methods and conditions, or selected according to the product specifications.

[0048] The toilet leak repairing method of the present invention specifically comprises the following steps:

[0049] S1 laid the ground film in all the corridors of the owner's room;

[0050] S2 Use hydrochloric acid or oxalic acid to disinfect and decontaminate the floor for 20 minutes. Use a steel wool to clean the floor stains.

[0051] S3 toilet leak repair: use professional tools to dismantle the toilet, clean the inside of the toilet, disinfect it with hydrochloric acid or oxalic acid, then use a dust-free cutting machine to cut the gap inside the toilet into 1.5-2mm wide, use a super silent vacuum cleaner to clean the gap and the area around the sewage outlet, then use foam-resistant waterproofing to waterproof the cut gap and the area around the sewage pipe, and raise the waterproofing around the sewage pipe to prevent leakage from the sewage outlet during later drainage.

[0052] S4 squat toilet leak repair: The interface between the squat toilet tank drain pipe and the squat toilet is prone to leaks. Use a dust-free cutting machine to cut the tiles at the interface, and use professional tools to break out the tiles. Then take out the drain pipe, clean it with clean water, and wipe off the moisture on the surface with a clean towel. Use special foam-resistant waterproofing to install and fix the drain pipe, and restore the tiles to their original state.

[0053] S5 Bathtub leak repair: Use special tools to clean the sealant on the corner gaps around the closed or open bathtub, and seal them evenly with anti-mildew and waterproof color sand beautifying agent.

[0054] Reconstruct the waterproof layer on the bottom layer of S6 caisson: Since it is not a full-excavation leak repair, the waterproof layer cannot be directly applied on the bottom layer. We can reconstruct the waterproof layer on the bottom floor. The method is: dig the tile opening at the pipe package of the bathroom to the bottom layer, open the pipe package at the bottom layer, and find the drain pipe. If there is water in the caisson, you need to use a pump to drain the water in the caisson, the drier the better, until no water comes out again, use the special crystal stone for the bathroom to stir it and introduce it into the caisson. The crystal stone is a liquid water agent that can be well diffused throughout the bottom floor of the sanitary base. The thickness of the waterproof layer is preferably 30mm. The crystal stone can react with the cement mortar layer to make the mortar layer soaked by the crystal stone become as hard as stone. In this way, the mortar layer becomes a waterproof layer, and a thick waterproof layer is reconstructed on the bottom layer.

[0055] Installation and treatment of S7 drainage system: After the reconstructed waterproof layer is dry, open an opening the size of a one-inch pipe at the lowest point of the pipe package, and use our drainage device pipe odor-proof port to obliquely insert it into the opened pipe port. The drainage device is divided into a water inlet and an odor-proof port. The odor-proof port is the water outlet. When there is no water, the odor-proof port is automatically closed to prevent the odor in the pipe from entering the bathroom caisson. This odor-proof device can also effectively prevent the water in the pipe from backflowing into the bathroom caisson. The length of the pipe is controlled at about 10mm, and it is inserted into the opening evenly and obliquely. The pipe exposed outside the pipe is bonded and smoothed with a foam-resistant waterproof glue, so that water in the bathroom can smoothly enter the drain pipe, and water in the drain pipe cannot enter the bathroom caisson. Use a bubble-resistant and water-absorbing fiber net to protect the drainage outlet of the drainage device, and put more water-absorbing fiber cloth outside the fiber net. The fiber net cannot be inserted into the drainage device to prevent the drainage device from being blocked after a long time. The drainage device is empty and has no pressure, and the water in the caisson will naturally drain into it. In this way, the water inlet of the drainage device will never be blocked by silt or other scale, causing the drainage system to be blocked in the later stage, and the caisson will be full of water and cause leakage again. This step ensures that the caisson will not be full of water, overflow or there will be water in the caisson and cause leakage again.

[0056] S8 uses a dust-free cutting machine to cut the gaps between bathroom floor and wall tiles into 1.5-2mm wide and 8-10mm deep joints.

[0057] S9 uses a super-quiet vacuum cleaner to clean the mud and water in the tile joints; then uses a special grout to hook out the loose sand and sand again, and cleans it again with a super-quiet vacuum cleaner. This will provide a better effect for the next step of mortar layer treatment.

[0058] Use a bag to twist it into a ball to block the S10 floor drain, preparing for the next step of making the crystal stone.

[0059] S11 Use the mortar layer under the tile joints to recreate the waterproof layer: open the crystal stone and stir it evenly, pour it evenly on the ground, and sweep it into the gaps with a broom until it can no longer penetrate. In this way, the tile gaps are full, and the mortar layer can fully absorb the crystal stone. The mortar layer reacts and crystallizes to become as hard as stone, thus achieving a waterproof effect. This waterproof layer does not shrink, expand, or age. This waterproof layer cannot be touched or stepped on, so it is a permanent waterproof layer.

[0060] S12 tile joints re-creation waterproof layer: After the gap crystallization stone is fully reacted, use a super silent vacuum cleaner to clean the excess material in the gap, and use mildew-proof waterproof epoxy colored sand to fill the ground gap and wall gap, and wipe off the excess material. This kind of gap waterproofing is beautiful, mildew-proof waterproof epoxy colored sand, no mold, good waterproof performance, high temperature resistance, abrasion resistance, no shrinkage, no expansion, and a variety of colors. In this way, the more you fill the leak, the more beautiful it will be.

[0061] S13 floor drain repair: Use a dust-free cutting machine to cut out the floor drain, then dig out the floor drain, and the dug-out part should be 20mm deeper than the floor drain pipe. Use a super-quiet vacuum cleaner to clean the floor drain, stir the foam-resistant waterproof into a paste (non-flowing state), fill the dug-out part with the waterproof paste, and install the floor drain back. In this way, the floor drain will not leak due to water flowing from the edge of the floor drain to the mortar layer during the use of water. The foam-resistant waterproof is in a rigid waterproof layer, with the same properties as cement, and does not shrink, age, deform, or evaporate. Therefore, the floor drain is a permanent waterproof layer after repair.

[0062] S14 Triangle valve and shower head leak repair: turn off the main valve of the water inlet pipe, remove all the triangle valves and shower heads in the bathroom, fill the space between the water pipe and the tile with foam-resistant waterproof material, and make a slope to prevent the triangle valve and shower head from not being tightened and seeping into the tile and entering the mortar layer to cause leakage. The triangle valve and shower head must be replaced with new sealing gaskets and water-stop tapes to ensure that the triangle valve and shower head will not leak again. After this is done, even if the owner replaces the triangle valve and shower head with a new one later, if they are not tightened, the water will flow to the outside of the tile. This is easy to see and easy to solve the problem. The water will never seep into the inside of the tile again, and it will not cause leakage again.

[0063] The foam-resistant waterproof material used in the present invention comprises:

[0064] 10 parts of ethylene ethanol, 0.68 parts of sodium sulfate, 0.06 parts of hydroxyethyl cellulose, 0.4 parts of propylene glycol polyoxypropylene polyethylene ether, 5.6 parts of water glass, 0.07 parts of borax, 1.2 parts of urea, 0.75 parts of sodium benzoate, 81.24 parts of distilled water, 0.02 parts of defoaming agent organosiloxane, 0.8 parts of toner mineral pigment, and 0.8 parts of antioxidant dialkyl dithiophosphate zinc.

[0065] Configuration process:

[0066] (1) The water requirement during the production process is very high, and it must be distilled water. Add distilled water to the reaction tank and heat it to 80 degrees, then start adding polyvinyl alcohol, and heat it to 90 degrees while stirring until the polyvinyl alcohol is completely dissolved.

[0067] (2) Stop heating, stir for 20-30 minutes, then add sodium sulfate, hydroxyethyl cellulose, propylene glycol polyoxypropylene polyethylene ether, antioxidant, and color powder, stir thoroughly for 40 minutes, then slowly add water glass while stirring, and stir for another 30 minutes after adding.

[0068] (3) Borax must be mixed with hot water and soaked for 10 hours. It can be used after it is completely melted. The mixed borax solution should be added in two times. The first time, add three quarters of the borax solution. After adding, stir it thoroughly for 30 minutes. Then add the remaining borax solution and stir it thoroughly. Finally, add urea and sodium benzoate and stir thoroughly.

[0069] Hydroxyethyl cellulose is a thickener, propylene glycol polyoxypropylene polyethylene ether is a defoaming agent, sodium benzoate is a preservative, urea is a stabilizer, and antioxidants have antioxidant and anti-aging properties.

[0070] Product features: strong practicality, no toxic gas or liquid emission during the production process, no harm to human health, no pollution to the environment, safe and reliable.

[0071] Waterproof performance and principle: The weight ratio of waterproof glue to cement is 1:2.5. After mixing with cement and brushing, the strength of cement will be enhanced, and the glue will block the capillaries in cement to achieve a permanent waterproof effect. When soaked in water, the waterproof glue will automatically expand and better block the capillaries in cement, thereby achieving a better waterproof effect. After the cement structure is stable, it will not age or deteriorate, and can resist blisters for a long time, so this waterproof can resist blisters for a long time.

[0072] The crystallized stone waterproof material used in the present invention is divided into component A and component B in the formula, wherein component A is composed of: 5 parts of 35% silica sol, 1.8 parts of stearic acid, 5.4 parts of 10% triethanolamine, 0.1 parts of sodium polyacrylate, 0.16 parts of sodium dodecylbenzene sulfonate, 1.6 parts of ethanol, and 85.94 parts of water;

[0073] Component B is composed of m-phenylenediamine (m-PDA) and MPD.

[0074] Configuration process:

[0075] (1) Add warm water to a stainless steel reaction kettle, gradually add stearic acid while stirring until it is completely dissolved, then slowly drop 10% triethanolamine solution, stir thoroughly and emulsify for about 1 hour to form a uniform emulsion.

[0076] (2) In another stainless steel container, weigh sodium polyacrylate and sodium dodecylbenzene sulfonate and mix them thoroughly. After dispersing them evenly with 90% ethanol, slowly add the mixture into the emulsion that is constantly stirred. After the dispersion and emulsification are completed in about 40 minutes, slowly add 35% silica sol dropwise, add water and stir for 30 minutes.

[0077] Curing agent, also known as hardener, curing agent or curing agent, is a kind of substance or mixture that promotes or controls the curing reaction. Curing agent is a chemical reaction such as condensation, ring closure, addition or catalysis that causes irreversible changes in the reaction. Curing is completed by adding curing (cross-linking) agents.

[0078] Product Features: This waterproof material is a composite of high-quality organic polymer materials and high-quality inorganic materials. It has the flexibility of organic materials and the durability of inorganic materials.

[0079] Product performance: It expands rapidly inside the cement mortar, blocks the micropores of the mortar layer, and penetrates into the micropores to produce water-insoluble substances and hydrophobic substances with the alkaline substances such as calcium hydroxide inside. It also plays the role of reducing water and early strength, greatly improving the hardness and density of the mortar layer, thus playing the role of moisture-proof, waterproof, anti-seepage and anti-aging.
