Description

Technical Field

[0001] The utility model belongs to the field of building waterproofing, and in particular relates to an exposed roof waterproofing structure. Background Art

[0002] Currently, there are several methods for waterproofing roofs: 1) Using traditional wet-laid waterproofing membranes for paving, and then applying a cement protective layer on the surface of the membrane to protect against foreign objects, resist ultraviolet rays, and resist aging. However, waterproofing membranes have some difficult-to-overcome drawbacks in practical applications. For example, multiple waterproofing membranes must be overlapped for paving. If the overlap is not properly positioned, it will cause leakage hazards. In addition, it is not convenient to use waterproofing membranes for waterproofing special-shaped roofs. 2) Using an interface treatment agent to treat the roof surface first and then applying a layer of reflective thermal insulation coating. The interface treatment agent is used to increase the adhesion of the reflective thermal insulation coating to the base surface. However, the reflective thermal insulation coating and the interface treatment agent generally have poor water resistance, resulting in poor overall waterproof performance, and the interface treatment agent is prone to cracking. 3) Applying waterproofing paint on the roof and then applying a cement protective layer. Due to the weight of the cement protective layer, this method can only be used on concrete roofs and is not suitable for metal roofs with lighter load-bearing capacity. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a roof sealing, waterproof, reflective and heat-insulating integrated structure suitable for waterproofing exposed roofs.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A roof sealing, waterproof, reflective and heat-insulating integrated structure comprises a waterproof sealing layer formed by coating a self-energy long-lasting waterproof paste on a base surface, and a reflective heat-insulating waterproof coating layer formed by coating a reflective heat-insulating waterproof coating on the outermost layer and drying it.

[0006] A reinforcement layer is also laid between the waterproof sealing layer and the reflective heat-insulating waterproof coating layer.

[0007] The reinforcement layer is tear-resistant cloth, mesh cloth or non-woven fabric.

[0008] The total thickness of the waterproof sealing layer and the reinforcement layer is 1.0 mm, and the thickness of the reflective heat-insulating waterproof coating layer is 0.5 mm.

[0009] The tear-resistant cloth is a core-skin composite long-fiber tear-resistant cloth, and weighs 40 grams per square meter.

[0010] When the self-energy long-lasting waterproof paste is coated on the metal base surface, the reinforcing layer is laid on the lap joints between adjacent metal plates.

[0011] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0012] 1. The utility model uses self-energy long-lasting waterproof paste to replace the traditional interface treatment agent. The self-energy long-lasting waterproof paste is based on a variety of polymer materials with rubber properties as functional base materials. It can be bonded to the interfaces of various materials (concrete, metal, plastic, etc.). It can not only bond the reflective heat-insulating waterproof coating to the base surface, but also has good water resistance. The waterproof layer formed has a creep-resistant and crack-resistant sealing waterproof effect.

[0013] 2. The outermost reflective heat-insulating waterproof coating layer has excellent UV resistance and light-reflecting properties, which can reduce the building's absorption of solar radiation heat, prevent the building surface from absorbing heat and causing the temperature to rise, and reduce the transfer of heat into the room, thereby achieving the purpose of reflective heat insulation.

[0014] 3. This utility model employs a layer of tear-resistant fabric as a reinforcement layer between the self-energy long-lasting waterproof paste and the reflective thermal insulation waterproof coating. The fabric acts as a framework within the composite layer. The pores and high specific surface area of ​​the fabric allow the coating to penetrate the fabric, forming a secure bond. The fabric's resistance to pulling and tearing prevents cracking in the coating, which could lead to waterproof failure. The combined use of tear-resistant fabric and coating not only improves waterproofing performance but also enhances surface smoothness during construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Example 1

[0020] See also Figure 1As shown, this embodiment discloses a roof sealing, waterproof, reflective and heat-insulating integrated structure, which includes a waterproof sealing layer 2 coated on a concrete base surface 1, a reinforcement layer 3 laid on the surface of the waterproof sealing layer 2, and a reflective heat-insulating waterproof coating layer 4 coated on the outermost layer.

[0021] The waterproof sealing layer 2 is formed by applying a self-energy long-lasting waterproof paste on the concrete base surface 1 and allowing it to dry. The self-energy long-lasting waterproof paste can adopt the applicant's previously authorized patented technology "waterproof sealing paste that undergoes chemical cross-linking and physical mortise and tenoning with cement" (Patent No. ZL201310276909.5). The self-energy long-lasting waterproof paste uses synthetic rubber latex and rubber-modified emulsified asphalt as raw materials, and adds functional additives. Through the coupling effect of the functional additives, the synthetic rubber molecules and asphalt molecules are coupled to form reactive macromolecules, which undergo chemical bonding and adsorption with the base surface, generating a strong chemical force. The rubber molecules and asphalt molecules can form physical adsorption when in contact with the cement or concrete base surface. Therefore, the waterproof paste can undergo physical mortise and tenoning and chemical cross-linking bonding with the cast-in-place concrete, producing an irreversible bonding effect, thereby organically growing together with the concrete. Self-energy long-lasting waterproof paste uses a variety of polymer materials with rubber properties as functional base materials. Through the grading of large and small molecular weights and the optimized combination of different molecular structures, the strength and toughness of the product are balanced. It can be bonded to the interfaces of various materials, and the waterproof layer formed has a creep-resistant and crack-resistant sealing and waterproof effect.

[0022] The reflective thermal insulation and waterproof coating layer 4 is formed by applying the reflective thermal insulation and waterproof coating onto the reinforcement layer 3 and allowing it to dry. The reflective thermal insulation and waterproof coating is primarily made from the following raw materials: polymer emulsion, synthetic rubber latex, reflective fillers, thermal insulation fillers, additives, and functional additives. Thermal insulation fillers include ceramic powder and hollow glass microspheres; additives include wetting agents, dispersants, thickeners, defoamers, fungicides, and preservatives; and functional additives include hydrophobic agents and crosslinking agents.

[0023] The reflective heat-insulating waterproof coating layer 4 has excellent UV resistance and light reflection properties, maintains a high solar reflectance for a long time, can reduce the building's absorption of solar radiation heat, prevent the building surface from absorbing heat and causing the temperature to rise, and reduce the transfer of heat into the room, thereby achieving the purpose of reflective insulation.

[0024] The reinforcement layer can be made of tear-resistant cloth, mesh cloth or non-woven fabric.

[0025] The tear-resistant cloth is a skin-core composite long fiber tear-resistant cloth. The skin-core composite long fiber tear-resistant cloth is made by bonding the long fibers together through hot pressing. The structure of the long fiber is that an outer layer of PE / PP / PA material is wrapped around the inner core of PET. The melting point of the outer layer material is lower than that of the PET in the inner core. During the hot pressing process, the outer layer materials of the long fibers are hot-melt bonded together while the inner core remains in a solid form, thereby forming a tear-resistant cloth with high connection strength and not easy to separate.

[0026] The weight of the core-sheath composite long fiber tear-resistant cloth is 40g / m 2 There are multiple pores on the core-skin composite long fiber tear-resistant cloth, which has a high specific surface area. The coating can penetrate into the pores and form a stable connection through bonding.

[0027] In addition to using skin-core composite long fiber tear-resistant cloth, mesh cloth can also be used. Mesh cloth has excellent physical and mechanical properties and adaptable application performance. It is a very suitable reinforcing material for waterproof coatings. On the one hand, the excellent mechanical tensile strength and the creep property of waterproof sealant produce a synergistic effect to resist cracking, vibration and other movements of the base layer. On the other hand, the uniform mesh size can well ensure the effective coating thickness of the waterproof coating and ensure the uniformity of the waterproof structure.

[0028] The reinforcement layer can also be made of non-woven fabric, which has excellent ductility and permeability. When used in combination with waterproof sealant, it can greatly improve the surface smoothness of the paint construction. It can also accelerate the drying speed of the paint through the penetration gaps of the non-woven fabric, while greatly improving the tensile properties of the paint layer.

[0029] The combined thickness of the waterproof sealant layer 2 and the reinforcement layer 3 is 1.0 mm, and the thickness of the reflective, heat-insulating, waterproof coating layer 4 is 0.5 mm, for a total thickness of 1.5 mm. To avoid coatings that are too thin, resulting in ineffective waterproofing, and too thick, resulting in excessive cost and waste, a thickness of 1.5 mm provides optimal waterproofing.

[0030] This embodiment is constructed by the following method (taking the use of tear-resistant cloth as the reinforcement layer as an example):

[0031] ⑴ Clean the base: clean the dust, floating slurry and other debris on the base surface, use cement mortar to repair the defects on the base surface, make arc chamfers at the inside corners and pipe roots, moisten the base, and sweep away excess water.

[0032] ⑵ Apply self-energy long-lasting waterproof paste and lay tear-resistant cloth

[0033] Apply the self-energy long-lasting waterproof paste to the nodes prone to leakage, such as pipe roots, gutters, downspouts, corners, etc., with a brush (or scraper, roller brush, spray, etc.). First apply a layer of self-energy long-lasting waterproof paste, then lay a layer of tear-resistant cloth to make the tear-resistant cloth completely soaked with the self-energy long-lasting waterproof paste.

[0034] For large-area painting: Apply the self-energy long-lasting waterproof paste evenly on the base surface, roll on the tear-resistant cloth while applying the paste, and gently roll to expel the air.

[0035] ⑶ Apply the outermost layer of reflective heat-insulating waterproof coating: After the bottom layer of waterproof paste has dried, evenly apply the reflective heat-insulating waterproof coating on the tear-resistant cloth so that the reflective heat-insulating waterproof coating is completely immersed in and covers the tear-resistant cloth.

[0036] Example 2

[0037] See also Figure 2 As shown, this embodiment discloses a roof sealing, waterproof, reflective and heat-insulating integrated structure, which includes a waterproof sealing layer 2 coated on a metal base surface 5, a reinforcement layer 3 laid on the surface of the waterproof sealing layer 2, and a reflective heat-insulating waterproof coating layer 4 coated on the outermost layer. The metal base surface 5 is a color steel tile roof, etc. The difference from Example 1 is that the reinforcement layer 3 used on the metal roof is only laid on the lap joint 6 between adjacent color steel plates, and during construction, the corrugated surface or ridges of the metal roof are not suitable for roller brushes and scrapers, and waterproof paste or reflective heat-insulating waterproof coating can be applied with a brush or spray.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
