Description

Technical Field

[0001] The present invention relates to the technical field of roof waterproofing, in particular to a super-durable self-cleaning roof waterproofing construction method based on penetration crystallization technology. Background Art

[0002] In the construction industry, roof waterproofing is crucial for ensuring a building's functionality and durability. Traditional roof waterproofing systems primarily rely on SBS waterproofing membranes and concrete cover layers to achieve waterproofing. However, this traditional system has numerous drawbacks. Over long-term use, SBS waterproofing membranes are susceptible to aging and cracking due to environmental factors such as UV radiation and drastic temperature fluctuations, significantly increasing the risk of leakage. Concrete cover layers are also prone to cracking due to shrinkage and external loads, reducing their waterproofing performance. Furthermore, traditional waterproofing systems are costly to maintain, requiring regular inspections and repairs. Their aesthetics are also lacking, making them difficult to meet the increasing functional and aesthetic demands of modern architecture.

[0003] Concrete sealant and curing agent, a colorless, transparent liquid, possesses numerous excellent properties. From production and application to subsequent use, it poses no harmful effects on human health or the ecological environment. It has a wide range of applications, including application to new and existing concrete, terrazzo, corundum wear-resistant materials, mortar, plaster, and all exposed concrete and building material surfaces. It effectively penetrates deep enough to chemically react with calcium hydroxide, calcium aluminide, and calcium silicate in concrete and stonework, forming inert crystals that embed into the concrete's pores, sealing microcracks and solidifying the concrete components into a solid, dense structure. This significantly enhances the concrete surface's hardness, density, wear resistance, strength, and durability, providing excellent protection for concrete structures in exposed environments. However, currently, a systematic and comprehensive application method for concrete sealant and curing agents in roof waterproofing has not yet been established, hindering their full potential in addressing the challenges of traditional roof waterproofing systems. Summary of the Invention

[0004] The present invention aims to solve the above problems and thus provide a super durable self-cleaning roof waterproofing construction method based on osmotic crystallization technology.

[0005] The present invention solves the above problems by adopting the following technical solutions: A super durable self-cleaning roof waterproofing construction method based on osmotic crystallization technology comprises the following steps: Step 1: Change the original three layers of 3mm thick waterproof membrane to two layers of 3mm thick waterproof layer structure, and complete the remaining roofing procedures according to the conventional construction process; Step 2: After the roof protection layer is maintained, clean the cement residue, dust, oil stains and garbage on the concrete base; Step 3: Spray the concrete sealant and curing agent evenly on the surface of the base layer. Increase the spraying amount on the raised parts of the base layer or the parts with faster penetration, so that the surface of the base layer remains moist with the concrete sealant and curing agent for a long enough time to ensure sufficient penetration reaction. Step 4: After the concrete sealant is cured, use a special grinder to grind and polish the roof.

[0006] Furthermore, in step three, the surface of the base layer is maintained in a wet state with the concrete sealing and curing agent for at least 30 minutes, ensuring that the sealing and curing agent has sufficient time to penetrate into the interior of the concrete protective layer and fully react with the chemical components therein to form a more complete inert crystal structure, thereby enhancing the density and integrity of the concrete surface.

[0007] Furthermore, in step four, a cement floor grinder is used, which is equipped with a coarser grinding wheel, a finer grinding wheel, and an even finer grinding wheel in sequence, to perform the first grinding, the second grinding, and the final grinding and polishing respectively; by using grinding wheels of different coarseness and fineness for grinding in stages, the concrete surface can be gradually refined, first dealing with the uneven parts of the base layer and the surface residues after the reaction, and then improving the surface finish through fine grinding; this stepped grinding method makes the surface flatter and smoother, which not only enhances the gloss performance after the sealing and curing agent acts, but also reduces surface pores and defects, further enhancing the surface's anti-fouling and self-cleaning ability, while making the roof appearance more uniform and beautiful.

[0008] Furthermore, in step 2, a broom, a shovel, and sandpaper are used to clean and remove cement residue and dust, a special detergent is used to clean oil stains, and a vacuum cleaner is used to remove residual tiny particles and dust; thus, weak points in waterproof performance caused by local impurity residues are reduced.

[0009] Furthermore, before proceeding to step three, the required amount of concrete sealing and curing agent is accurately calculated based on the actual construction area of ​​the roof; the amount is accurately calculated to avoid insufficient penetration and poor curing effect due to insufficient amount.

[0010] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: This method enhances the roof's overall waterproofing capabilities and reduces the likelihood of leakage by adjusting the number of waterproof membrane layers and combining the penetration of a sealing and curing agent into the concrete protective layer. The sealing and curing agent can form a denser structure in the concrete protective layer, reducing the path for water penetration and synergizing with the adjusted waterproof membrane layer to enhance the waterproofing effect. The sealing and curing agent penetrates into the concrete cover and reacts, which helps to improve the density and integrity of the concrete and reduce the cracking of the cover caused by shrinkage and load, thereby maintaining its long-term structural integrity and waterproof performance. The hardness, wear resistance and durability of the concrete cover of the roof treated with this method are improved, which can better resist the erosion of external environmental factors, reduce the need for repairs and renovations due to structural damage or performance degradation, and thus reduce long-term maintenance costs. The grinding and polishing steps during the construction process, combined with the glossy effect that gradually emerges during the use of the sealing and curing agent, improve the appearance of the roof, enhance the aesthetics of the building, and meet the dual needs of modern architecture for functionality and aesthetics.

[0012] A super durable self-cleaning roof waterproofing construction method based on osmotic crystallization technology comprises the following steps: Step 1: Change the original three layers of 3mm thick waterproof membrane to two layers of 3mm thick waterproof layer structure, and complete the remaining roofing procedures according to the conventional construction process; Step 2: After the roof protection layer is maintained, clean the cement residue, dust, oil stains and garbage on the concrete base; Step 3: Spray the concrete sealant and curing agent evenly on the surface of the base layer. Increase the spraying amount on the raised parts of the base layer or the parts with faster penetration, so that the surface of the base layer remains moist with the concrete sealant and curing agent for a long enough time to ensure sufficient penetration reaction. Step 4: After the concrete sealant is cured, use a special grinder to grind and polish the roof.

[0013] In step three, the surface of the base layer is kept moist with the concrete sealer and curing agent for at least 30 minutes; this ensures that the sealer and curing agent has sufficient time to penetrate into the concrete protective layer and fully react with the chemical components therein to form a more complete inert crystal structure, thereby enhancing the density and integrity of the concrete surface.

[0014] In step four, use a cement floor grinder equipped with a coarser grinding wheel, a finer grinding wheel, and an even finer grinding wheel to perform the first grinding, the second grinding, and the final grinding and polishing respectively. By using grinding wheels of different coarseness and fineness for grinding in stages, the concrete surface can be gradually refined. First, the uneven parts of the base layer and the surface residues after the reaction are dealt with, and then the surface finish is improved through fine grinding. This stepped grinding method makes the surface flatter and smoother, which not only enhances the gloss performance after the sealing and curing agent acts, but also reduces surface pores and defects, further enhancing the surface's anti-fouling and self-cleaning ability, while making the roof appearance more uniform and beautiful.

[0015] In step 2, use a broom, shovel, and sandpaper to clean and remove cement residue and dust, use a special detergent to clean oil stains, and use a vacuum cleaner to remove residual tiny particles and dust; reduce weak points in waterproof performance caused by local impurity residues.

[0016] Before proceeding to step three, accurately calculate the required amount of concrete sealing and curing agent based on the actual construction area of ​​the roof; accurately calculate the amount to avoid insufficient penetration and poor curing effect due to insufficient amount.

[0017] This method enhances the roof's overall waterproofing capabilities and reduces the likelihood of leakage by adjusting the number of waterproof membrane layers and combining the penetration of a sealing and curing agent into the concrete protective layer. The sealing and curing agent can form a denser structure in the concrete protective layer, reducing the path for water penetration and synergizing with the adjusted waterproof membrane layer to enhance the waterproofing effect. The sealing and curing agent penetrates into the concrete cover and reacts, which helps to improve the density and integrity of the concrete and reduce the cracking of the cover caused by shrinkage and load, thereby maintaining its long-term structural integrity and waterproof performance. The hardness, wear resistance and durability of the concrete cover of the roof treated with this method are improved, which can better resist the erosion of external environmental factors, reduce the need for repairs and renovations due to structural damage or performance degradation, and thus reduce long-term maintenance costs. The grinding and polishing steps during the construction process, combined with the glossy effect that gradually emerges during the use of the sealing and curing agent, improve the appearance of the roof, enhance the aesthetics of the building, and meet the dual needs of modern architecture for functionality and aesthetics.
