Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an aerogel felt sandwich thermal insulation and decorative integrated board structure. Background Art

[0002] Vigorously developing ultra-low energy buildings is not only a future trend in the construction industry but also a key component in achieving carbon peak and carbon neutrality. Ultra-low energy buildings offer numerous advantages, including strong insulation, excellent airtightness, low energy consumption, low noise levels, and improved air quality. They can significantly reduce fossil energy consumption, earning them the nickname "breathing green buildings." Due to their ultra-low energy consumption and exceptional quality, ultra-low energy buildings are becoming a new trend in building energy conservation.

[0003] However, ultra-low energy buildings place high demands on building materials. The materials used must not only have an ultra-low heat transfer coefficient to reduce energy consumption, but must also excel in various other properties to ensure the safety and stability of the building.

[0004] Currently, building energy consumption in my country accounts for 36% of total societal energy consumption. Therefore, improving building energy conservation is an inevitable choice for my country to achieve sustainable development and energy conservation and emission reduction. Building energy consumption primarily comes from energy losses in the maintenance structure, and walls form the core of the building envelope. Therefore, effective wall insulation is a reliable way to achieve building energy conservation. In my country, wall insulation primarily comes from exterior wall insulation and interior wall insulation. Exterior wall insulation not only protects the building's main structure and extends its service life, but also increases usable floor space by preventing heat dissipation channels formed by exterior wall ring beams, structural columns and beams, and doors and windows, effectively overcoming the "thermal bridge" phenomenon that is difficult to address with interior wall insulation. Therefore, exterior wall insulation materials have become the mainstream form of building wall insulation in my country.

[0005] Insulation-decorative integrated panels are a key material for exterior wall insulation and energy-saving systems, combining both insulation and decoration. Due to their uniform appearance, ease of construction, minimal climatic influence, and significantly shortened construction schedules, they are increasingly being used in exterior wall insulation and energy-saving systems. However, existing insulation-decorative integrated panels also require thermal insulation and fire resistance, an ultra-low heat transfer coefficient to reduce energy consumption, and excellent other performance characteristics to ensure safety and stability.

[0006] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0007] Existing thermal insulation and decorative integrated panels also put forward requirements for thermal insulation and fire prevention, and at the same time require an ultra-low heat transfer coefficient to reduce energy consumption, and require other excellent performances to meet safety and stability. Therefore, the utility model provides an aerogel felt sandwich thermal insulation and decorative integrated panel structure to solve the above problems.

[0008] The utility model provides an aerogel felt sandwich insulation and decorative integrated panel structure, which comprises a calcium silicate board, an aerogel felt layer, an adhesive layer, a foamed ceramic board and a decorative coating stacked in sequence, wherein the calcium silicate board and the aerogel felt layer are bonded by a two-component polyurethane adhesive, the aerogel felt layer and the foamed ceramic board are compounded by the adhesive layer, and reinforcement layers are further provided on the outer surfaces of both sides of the foamed ceramic board.

[0009] In one implementation, the aerogel felt layer is a nano-silica aerogel felt layer.

[0010] In one implementation, the bonding layer is a bonding mortar layer and / or a polyurethane glue layer.

[0011] In one implementation, the reinforcement layer includes any one of a glass fiber mesh cloth layer, a steel wire mesh, a carbon fiber cloth, ductile concrete, and polymer fibers.

[0012] In one implementation, the decorative coating is any one of a real stone paint layer, a water-in-water layer, and a sand-in-water layer.

[0013] In one implementation, the thickness of the aerogel felt layer is 1-4 cm, the thickness of the calcium silicate board is 0.4-1 cm, and the thickness of the foamed ceramic board is 1-5 cm.

[0014] In one implementation, the calcium silicate board and the aerogel felt layer are bonded by polymer adhesive.

[0015] Beneficial effects: The aerogel felt sandwich insulation and decorative integrated board structure provided by the utility model is composited by simultaneously adopting calcium silicate board, aerogel felt layer and foamed ceramic board, combining the characteristics of calcium silicate board with light weight, high strength, good thermal insulation and durability, high specific surface area, low thermal conductivity and good thermal insulation performance of aerogel felt layer, and low thermal conductivity coefficient, excellent thermal insulation and fireproof and sound insulation performance of foamed ceramic board, so that the structure has excellent thermal insulation performance and ultra-low heat transfer coefficient. At the same time, the fire protection grade of the structure is A, which can significantly improve the comprehensive performance of the aerogel felt sandwich insulation and decorative integrated board, meet the needs of ultra-low energy consumption buildings, achieve better insulation, sound insulation, fireproof and durability effects, while reducing building energy consumption and improving living comfort, and provide an aerogel felt sandwich insulation and decorative integrated board structure with light weight, good thermal insulation performance, high fireproof and waterproof grades.

[0025] See also Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the overall structure of the aerogel felt sandwich insulation and decorative integrated panel structure provided by the utility model.

[0026] The utility model provides an aerogel felt sandwich insulation and decorative integrated panel structure, which includes a calcium silicate board 1, an aerogel felt layer 2, an adhesive layer 3, a foamed ceramic board 4 and a decorative coating 5 stacked in sequence. The calcium silicate board 1 and the aerogel felt layer 2 are bonded by a two-component polyurethane adhesive, the aerogel felt layer 2 and the foamed ceramic board 4 are compounded by the adhesive layer 3, and a reinforcement layer 6 is further provided on the outer surfaces of both sides of the foamed ceramic board 4.

[0027] Calcium silicate board 1 is a building board primarily made from lime, silicate, and inorganic fiber reinforcement. It features lightweight, high strength, excellent thermal insulation, durability, and superior processability and construction properties. It is primarily used in ceilings, partitions, and as a fireproofing material for steel columns and beams. Aerogel felt 2 boasts thermal stability and thermal shock resistance exceeding that of quartz glass, offering superior insulation and warmth retention compared to mineral wool. It is also non-flammable, making it an excellent fireproof material. It also offers excellent sound insulation, over four times that of standard metal and glass.

[0028] Preferably, the calcium silicate board 1 and the aerogel felt layer 2 are secured by a plastic expansion plug (not shown), the outer end of which is flush with the outer surface of the calcium silicate board. The multi-layer composite structure of the board and the method of securing it with the plastic expansion plug simplify the installation process, saving construction time and labor costs, and are less affected by climatic conditions, significantly shortening the construction period.

[0029] In other embodiments, polymer glue can also be used as a bond between the calcium silicate board 1 and the aerogel felt layer 2, which further reduces the weight of the aerogel felt sandwich insulation and decorative integrated panel structure and improves the fire resistance. At the same time, it is also beneficial to extend the service life of the aerogel felt sandwich insulation and decorative integrated panel structure and reduce the manufacturing cost of the aerogel felt sandwich insulation and decorative integrated panel structure.

[0030] Furthermore, the aerogel felt layer 2 is a nano-silica aerogel felt layer. This material, with its extremely low thermal conductivity, significantly improves the insulation performance of the overall board, effectively reducing building energy consumption. The composite structure of the calcium silicate board 1, aerogel felt layer 2, and foamed ceramic board 4 is secured via a bonding mortar layer and / or polyurethane adhesive layer, providing a high-strength and stable structure and extending the service life of the board.

[0031] Specifically, the bonding layer 3 is a bonding mortar layer and / or a polyurethane adhesive layer. The bonding layer 3 can also be a reinforced adhesive layer or an epoxy resin adhesive layer for stretch bonding. Using a reinforced adhesive layer or an epoxy resin adhesive layer for stretch bonding as the bonding layer 3 can provide strong tensile strength and adhesion, helping to ensure the stability and durability of the entire board, reducing deformation or degradation caused by temperature changes, and thus extending the service life.

[0032] Specifically, the reinforcement layer 6 includes any one of a glass fiber mesh cloth layer, a steel wire mesh, a carbon fiber cloth, ductile concrete and polymer fibers. Among them, the glass fiber mesh cloth layer can improve the tensile strength and crack resistance, enhance the overall rigidity and stability of the board, and prevent cracking and deformation caused by temperature changes and loads. The steel wire mesh can enhance the impact resistance and structural strength of the board, and is particularly suitable for construction applications that require high strength and durability. Carbon fiber cloth can provide high strength and lightweight reinforcement effects, while having corrosion resistance and high temperature resistance, and is suitable for high-demand engineering projects. Polymer fibers can provide good flexibility and toughness, enhance the crack resistance of the board, while maintaining a low weight. The reinforcement layer 6 enhances the tensile, compressive and crack resistance of the foamed ceramic board 4, and improves the overall mechanical strength and durability.

[0033] Specifically, the decorative coating 5 can be any of a natural stone paint layer, a water-in-water layer, and a water-in-sand layer, providing an aesthetically pleasing exterior, meeting the requirements for integrated building exterior wall decoration, and reducing construction steps and time. The decorative coating 5 enhances overall aesthetics and protective properties, increases surface wear resistance and anti-pollution capabilities, and improves the overall value and applicability of the product.

[0034] Specifically, the thickness of the aerogel felt layer 2 is 1-4 cm, the thickness of the calcium silicate board 1 is 0.4-1 cm, and the thickness of the foamed ceramic board 4 is 1-5 cm. The thickness design of each layer of material not only ensures sufficient thermal insulation effect, but also controls the overall thickness, saves space, and reduces the overall weight of the building.

[0035] The above-mentioned aerogel felt sandwich insulation and decorative integrated board structure is a structure in which a calcium silicate board 1 is composited as the backing board of an aerogel felt layer 2, and then bonded and composited by an adhesive layer 3 and a foamed ceramic board 4 with a decorative coating 5. The aerogel felt layer 2 has an extremely high specific surface area, extremely low thermal conductivity, and good thermal insulation performance due to its unique nanoporous structure and extremely low density. At the same time, the foamed ceramic board 4 with the decorative layer 5 also has excellent properties such as low thermal conductivity, thermal insulation, fire resistance, and sound insulation. As a result, the structure has excellent thermal insulation performance and an ultra-low heat transfer coefficient, meeting the requirements of energy-saving standards. At the same time, the structure has a fire protection grade of Class A, which greatly reduces the thermal conductivity of the entire board, increases thermal resistance, and has a good thermal insulation effect. The overall thickness of the insulation board is significantly reduced, saving a lot of material. The structure is industrially produced with stable quality and performance. It is simple and quick to install by on-site adhesive anchoring. The addition of a foamed ceramic panel (4) with a decorative coating (5) reduces the number of exterior wall insulation construction steps, lowers labor costs, and shortens the construction period. This aerogel felt sandwich insulation and decorative integrated panel structure offers the advantages of high thermal insulation efficiency, labor and material savings, fire safety, and weather resistance. This overcomes the difficulty of combining fire protection with high energy efficiency in insulation materials, and is far superior to commonly used materials on the market in terms of safety, fire protection, material, labor, and time savings. It represents a major breakthrough in the field of energy-saving building materials.

[0036] To sum up, the aerogel felt sandwich insulation and decorative integrated board structure provided by the utility model is composited by simultaneously adopting calcium silicate board, aerogel felt layer and foamed ceramic board, combining the characteristics of calcium silicate board of light weight, high strength, good thermal insulation and durability, high specific surface area, low thermal conductivity and good thermal insulation performance of aerogel felt layer, and low thermal conductivity coefficient, excellent thermal insulation and fireproof and sound insulation performance of foamed ceramic board, so that the structure has excellent thermal insulation performance and ultra-low heat transfer coefficient. At the same time, the fire protection grade of the structure is A, which can significantly improve the comprehensive performance of the aerogel felt sandwich insulation and decorative integrated board, meet the needs of ultra-low energy consumption buildings, achieve better thermal insulation, sound insulation, fireproof and durability effects, and at the same time reduce building energy consumption and improve living comfort.
