Description

Technical Field

[0001] The invention relates to the technical field of building waterproof reconstruction, and in particular to a wall waterproof reconstruction process. Background Art

[0002] The exterior walls of buildings are usually painted with cement plaster or putty to decorate the exterior walls. Some exterior walls are painted with paint and tiled to decorate and protect the walls. However, the exterior walls of some older buildings are usually painted with cement plaster or putty. However, due to long-term exposure to wind, rain and sunlight, the exterior walls will crack, powder, peel, discolor, etc., making the walls prone to water seepage, further affecting the service life of the walls.

[0003] At present, when cracks, peeling and water seepage occur on the external wall, the cracked or peeling parts are usually removed directly, and then directly coated with concrete. After the concrete is dry, a layer of waterproof paint is applied. However, the connection performance between the concrete and the wall base is not good by directly coating the concrete. Under the influence of sunlight and rain, it is easy to hollow out and there is a possibility of secondary water seepage. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a wall waterproofing renovation process, by first filling the places where water seepage or cracks exist in the wall, and when coating the composite concrete, by coating a transition layer, so that under the action of the filler, the transition layer and the composite concrete, not only the connection strength between the composite concrete and the wall base can be enhanced, but also the waterproof performance can be enhanced and the possibility of water seepage can be reduced.

[0005] The present invention solves the above technical problems by the following technical means:

[0006] A wall waterproofing reconstruction process comprises the following steps:

[0007] S1. Mark the leaking area, expand the area around the mark by 10 to 20 cm, and then re-mark the area. Remove the re-marked area.

[0008] S2. Clean the demolished parts, chisel the parts with gaps along the gaps by 0.5 to 15 cm, clean the chiseled materials, and inject modified fillers;

[0009] S3. After the modified filler is cured, apply a transition layer and then apply concrete. After the concrete solidifies, apply a waterproof coating to complete the wall waterproofing transformation.

[0010] By first marking the parts where water leaks or seepage exists, and marking the outside of the seepage or leakage again, the possibility of water leaks or seepage on the outside of the seepage or leakage is avoided, and the parts with gaps are excavated, and the cracked parts corroded by rainwater are removed, and then modified fillers are injected to fill the cracked parts and fully bond them to the cracked wall surface to avoid rainwater from penetrating again. Then, a transition layer is applied to allow the concrete to be fully and firmly bonded to the wall base surface. The concrete uses compound concrete, which has a smaller shrinkage rate and stronger adhesion and waterproofness, and can avoid rainwater penetration, hollowing, etc. Finally, a waterproof coating is applied to the surface of the compound concrete to achieve a three-layer anti-seepage effect.

[0011] Furthermore, the step S1 also includes building a construction frame, and after the construction frame is built, a mesh fence is set around the re-marked position.

[0012] By setting up mesh fences at the marked locations, the splashing and falling of debris during demolition can be reduced.

[0013] Furthermore, in the step S1, after the mesh fence is fixed, the re-marked area and the surrounding area are rinsed with clean water, and whether re-marking is required is determined based on the water stain penetration.

[0014] By soaking the marked area and surrounding walls with clean water, mark as many surrounding walls as possible that may have seepage or leakage to avoid omissions.

[0015] Furthermore, in the step S1, when the water stain infiltration is larger than the re-marked range, a third marking is performed at 3 to 5 cm from the water stain infiltration boundary; when the water stain infiltration is smaller than the re-marked range, the re-marked range is maintained.

[0016] According to the extent of water stains, all areas where water seepage or leakage may occur will be marked to reduce the occurrence of secondary water seepage or leakage.

[0017] Furthermore, in the step S2, when injecting the modified filler, a clean cardboard is used to partially cover the gap, and when the modified filler is cured, the cardboard is peeled off and the residue is removed.

[0018] By using clean cardboard to cover the gap, the loss of modified filler can be reduced and the amount of modified filler used can be reduced.

[0019] Further, the preparation of the modified filler comprises the following steps:

[0020] A1. Place calcium silicate in a crusher, crush it, and pass it through a 300-500 mesh sieve to obtain micron-grade calcium silicate;

[0021] A11. Place micron-sized calcium silicate in epoxy resin and treat it with ultrasonic waves for 10 to 30 minutes to obtain a modified filler.

[0022] Calcium silicate is a good inorganic filler. It is mixed with thermosetting resin to improve the chemical and moisture resistance of thermosetting resin, reduce molding shrinkage, and has excellent dimensional stability, toughness, hardness, electrical and thermal insulation. Epoxy resin has good bonding strength and chemical resistance, and low shrinkage. By first crushing calcium silicate and then mixing it evenly with epoxy resin through ultrasound, on the one hand, it can form resin mortar to enhance the filling performance of gaps, and on the other hand, it can further reduce the shrinkage, so that the modified filler can better fill the gaps.

[0023] In this embodiment, the epoxy resin is epoxy resin 6101, and the power of the ultrasonic wave is 200-300W.

[0024] Furthermore, the mass ratio of the calcium silicate to the epoxy resin is (0.2-0.75):1.

[0025] Furthermore, in the step S3, the transition layer is a flexible resin, and the coating thickness of the flexible resin is 1 to 3 mm.

[0026] In this embodiment, the flexible resin is FUCHEM810, which has the effects of corrosion resistance, high elongation and low linear shrinkage. By selecting the flexible resin as the transition layer, the problem of stress difference between the concrete base layer and the resin mortar surface layer can be solved, while ensuring that the resin mortar itself does not crack.

[0027] Furthermore, in the step S3, the concrete is a composite concrete, and the preparation of the composite concrete comprises the following steps:

[0028] The mortar and epoxy resin are mixed evenly, and then the dispersant and basalt fiber are added, and mechanical stirring is performed for 10 to 20 minutes. After the stirring is completed, the compounded concrete is obtained.

[0029] In this embodiment, the epoxy resin is epoxy resin 6101. By mixing the epoxy resin with mortar to form a resin mortar, and then adding a dispersant and basalt fiber, the waterproof, weather resistance and bonding properties of the composite concrete can be improved, the shrinkage rate of the composite concrete can be reduced, the bonding performance with the concrete base can be improved, and the waterproof performance can be further improved. Combined with the waterproof coating applied on the outermost layer, a three-layer waterproof effect can be achieved.

[0030] Furthermore, the dispersant is one or a combination of polyethylene wax, polyethylene glycol 200, paraffin wax, and microcrystalline wax.

[0031] In this embodiment, the dispersant is preferably polyethylene glycol 200, which has good dispersibility and bonding properties, so that the basalt fiber can be evenly dispersed in the compound concrete, further reducing the shrinkage rate of the concrete and the possibility of hollowing.

[0032] The invention adopting the above technical solution has the following beneficial effects:

[0033] By first marking the parts where water leaks or seepage exists, and marking the outside of the seepage or leakage again, the possibility of water leaks or seepage on the outside of the seepage or leakage is avoided, and the parts with gaps are excavated, and the cracked parts corroded by rainwater are removed, and then modified fillers are injected to fill the cracked parts and fully bond them to the cracked wall surface to avoid rainwater from penetrating again. Then, a transition layer is applied to allow the concrete to be fully and firmly bonded to the wall base surface. The concrete uses compound concrete, which has a smaller shrinkage rate and stronger adhesion and waterproofness, and can avoid rainwater penetration, hollowing, etc. Finally, a waterproof coating is applied to the surface of the compound concrete to achieve a three-layer anti-seepage effect.

[0082] Example 6, Preparation of Waterproof Body III

[0083] Preparation of modified fillers

[0084] A1. Place 20 parts by mass of calcium silicate in a crusher, crush it, and pass it through a 300-500 mesh sieve to obtain micron-grade calcium silicate;

[0085] A11. Place 7.5 parts by mass of micron-sized calcium silicate in 10 parts by mass of epoxy resin 6101, and perform ultrasonic treatment for 30 minutes at a power of 300 W to obtain a modified filler.

[0086] Preparation of compound concrete

[0087] 10 parts by mass of mortar and 18 parts by mass of epoxy resin 6101 were mixed evenly by mechanical stirring, and then 1.2 parts by mass of polyethylene glycol 200 and 3.2 parts by mass of basalt fiber were added and mechanically stirred for 15 minutes.

There was no cracking, hollowing or degumming as a whole, and the overall shrinkage rate was less than 0.23%, indicating that the modified filler, the transition layer and the composite concrete can be firmly bonded together through the mutual cooperation of the modified filler, which can not only enhance the connection strength between the composite concrete and the wall base, but also enhance the waterproof performance and reduce the possibility of water seepage.

[0089] Example 7 (Comparative Example 1), Preparation of Waterproof Body IV

The waterproof body was soaked in clean water for 30 days. After the soaking was completed, it was taken out and observed. There was no cracking or hollowing as a whole, and the overall shrinkage rate was less than 0.25%. However, debonding occurred on some edges, indicating that the addition of a transition layer can enhance the bonding strength between the modified filler and the composite concrete.

[0091] Example 8 (Comparative Example 2), Preparation of Waterproof Body 5

[0092] Ordinary cement and mortar are mixed and filled into the mold with a filling thickness of 3 cm. After the concrete solidifies, acrylic resin is directly coated. After the acrylic resin is cured, a waterproof body is obtained. The waterproof body is placed in clean water and soaked for 30 days. After the soaking is completed, it is taken out and observed. There is no cracking as a whole, but the overall shrinkage rate of the acrylic resin layer is greater than 1.1%, and there is debonding at the edge. This shows that when acrylic acid is directly coated on the part of the wall that is seeping or leaking, and then ordinary cement is directly coated for waterproofing, the waterproofing time limit is not long and the waterproofing effect is not good.

[0093] Example 9 (Comparative Example 3), Preparation of Waterproof Body 6

[0094] Ordinary cement and mortar are mixed and filled into the mold with a filling thickness of 3 cm. After the concrete solidifies, polyurethane resin is directly coated. After the polyurethane resin is cured, a waterproof body is obtained. The waterproof body is placed in clean water and soaked for 30 days. After the soaking is completed, it is taken out and observed. There is no cracking as a whole, but the overall shrinkage rate of the polyurethane resin layer is greater than 0.84%, and there is partial debonding at the edge. This shows that when polyurethane is directly coated on the part of the wall that is seeping or leaking, and then ordinary cement is directly coated for waterproofing, the waterproofing time limit is not long and the waterproofing effect is not good.

[0095] Through Examples 1 to 3, it is explained that by first marking the parts where water leakage or seepage exists, and marking the outside of the seepage or leakage again, the possibility of water leakage or seepage on the outside of the seepage or leakage is avoided, and the parts where gaps exist are excavated, and the cracked parts corroded by rainwater are removed, and then the cracked parts are filled by injecting modified fillers, and are fully bonded to the cracked wall surface to avoid rainwater from penetrating again, and then by coating a transition layer, the concrete can be fully and firmly bonded to the wall base surface, and the concrete adopts compound concrete, which has a smaller shrinkage rate and stronger adhesion and waterproofness, and can avoid rainwater penetration, hollowing, etc. Finally, a waterproof coating is coated on the surface of the compound concrete to achieve a multi-layer anti-seepage effect, thereby increasing the water discharge life of the modified wall, and the modification method in this embodiment can also be used for concrete pools, exterior walls and other walls that are directly in contact with the external environment.

[0096] Through the above-mentioned Examples 4 to 9, it can be explained that by adopting the mutual cooperation of modified fillers, transition layers and composite concrete, compared with the method of directly coating adhesives on the seepage or leakage parts and then coating concrete, it has a smaller shrinkage rate (that is, it reduces the possibility of hollowing and cracking) and stronger adhesion and waterproofness, and can avoid rainwater penetration, hollowing, etc. Finally, a waterproof coating is coated on the surface of the composite concrete to achieve a multi-layer anti-seepage effect, thereby improving the water release time limit of the wall after the renovation.

[0097] It should be noted that if no specific experimental steps or conditions are specified in the examples, the conventional experimental steps or conditions described in the literature in the field can be used. If no manufacturer is specified for the reagents or instruments used, they are all conventional reagent products that can be purchased commercially.
