Description
Technical Field
[0001] This application relates to the field of insulation board technology, specifically to composite insulation boards with fireproof and heat insulation functions. Background Technology
[0002] Insulation board is a rigid foam plastic board made from polystyrene resin as the raw material, along with other raw materials and polymers. It is manufactured by heating and mixing the materials while injecting a catalyst, and then extruding and molding it. Its scientific name is extruded polystyrene foam for thermal insulation (XPS for short). XPS has a perfect closed-cell honeycomb structure, which gives XPS boards extremely low water absorption (almost no water absorption), low thermal conductivity, high compressive strength, and aging resistance (almost no aging and decomposition under normal use).
[0003] However, most existing insulation boards have poor fire resistance and heat insulation properties, and also lack a variety of composite functions such as waterproofing, moisture resistance, and breathability. To overcome these technical challenges, the new composite insulation board achieves functional integration and performance improvement through an innovative layered structural design. The outer weather-resistant and impact-resistant layer uses glass fiber reinforced concrete (GRC) board. Through a three-dimensional interlaced glass fiber reinforcement structure, its wind pressure resistance is greatly enhanced. The middle fire-resistant and heat-insulating core layer uses a composite system of nano-aerogel and rock wool. The former blocks heat conduction with its ultra-low thermal conductivity, while the latter provides fire protection with its Class A non-combustible properties. When exposed to fire, the rock wool fibers expand to form a heat insulation barrier, and the nano-aerogel further inhibits heat radiation, achieving a dual fire-resistant and heat-insulating effect. The inner moisture-proof and breathable layer is composed of a polyvinyl alcohol film and aluminum foil composite. Its unique microporous structure allows it to effectively prevent liquid water penetration while maintaining a water vapor permeability of ≤0.5g / (㎡・24h). This prevents external moisture from entering while allowing internal moisture to escape, completely solving the problem of traditional insulation boards being "waterproof but not breathable, breathable but not waterproof." The contradiction is resolved by the three-layer structure working together to fundamentally solve the performance shortcomings of traditional insulation boards. To address the above problems, a composite insulation board with fireproof and heat insulation functions has been proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a composite insulation board with fireproof and heat-insulating functions, which has advantages such as better fireproof and heat-insulating effects and multiple composite protections, thus solving the problems mentioned in the background technology.
[0005] To achieve the above objectives, this application provides the following technical solution: a composite insulation board with fireproof and heat-insulating functions, comprising a weather-resistant and impact-resistant layer, a fireproof and heat-insulating core layer, and a moisture-proof and breathable layer. The weather-resistant and impact-resistant layer contains a glass fiber reinforced concrete board, the fireproof and heat-insulating core layer contains nano-aerogel and rock wool, and the moisture-proof and breathable layer contains a polyvinyl alcohol film and aluminum foil. The weather-resistant and impact-resistant layer, the fireproof and heat-insulating core layer, and the moisture-proof and breathable layer are fixedly connected to each other.
[0006] Through the above scheme, the composite insulation board consists of a weather-resistant and impact-resistant layer, a fireproof and heat-insulating core layer, and a moisture-proof and breathable layer. The layers are tightly fixed and connected to form an organic whole. The weather-resistant and impact-resistant layer is equipped with a glass fiber reinforced concrete board. The high strength of glass fiber and the rigidity of concrete give the insulation board excellent wind pressure resistance. The fireproof and heat-insulating core layer adopts a composite method of nano-aerogel and rock wool. The ultra-low thermal conductivity of nano-aerogel can effectively block heat transfer, while rock wool provides reliable fire protection with its Class A non-combustible properties. The moisture-proof and breathable layer is composed of a polyvinyl alcohol film and aluminum foil to achieve a balance between waterproofing and breathability, effectively preventing internal condensation and material moisture absorption.
[0007] Furthermore, the side surface of the glass fiber reinforced concrete panel is coated with a photocatalytic coating.
[0008] Through the above method, the photocatalytic coating applied to the side of the glass fiber reinforced concrete panel can degrade pollutants in the air and achieve a self-cleaning effect under ultraviolet irradiation.
[0009] Furthermore, four fixing blocks are overlapped on the side of the glass fiber reinforced concrete panel, and screws are threadedly connected to the inside of the fixing blocks and the inside of the glass fiber reinforced concrete panel. Cadmium telluride thin-film solar cells are fixedly installed on the surface of the four fixing blocks.
[0010] With the above solution, the side-mounted fixing blocks are connected to the glass fiber reinforced concrete board by screws. The cadmium telluride thin-film solar cells installed on the surface of the fixing blocks give the insulation board the function of generating electricity, achieving the dual benefits of energy saving and power generation. At the same time, if the cadmium telluride thin-film solar cells are damaged, they can be disassembled and maintained by unscrewing the screws.
[0011] Furthermore, the glass fiber reinforced concrete slab has expanded graphite on its side, and magnesium hydroxide is disposed on the side of the expanded graphite.
[0012] Through the above scheme, the combination of expanded graphite and magnesium hydroxide allows the expanded graphite to form a heat-insulating carbon layer when exposed to fire, while the magnesium hydroxide decomposes to release water vapor for cooling, further enhancing the fire resistance.
[0013] Furthermore, a first carbon fiber mesh is fixedly connected to the surface of the nano-aerogel, and a second carbon fiber mesh is fixedly connected to the surface of the rock wool.
[0014] Through the above scheme, in the fireproof and heat-insulating core layer, the first carbon fiber mesh and the second carbon fiber mesh are fixedly connected to the surface of the nano-aerogel and the rock wool, respectively, to enhance the structural stability and deformation resistance of the material.
[0015] Furthermore, a honeycomb skeleton is fixedly connected to the side of the second carbon fiber mesh.
[0016] Through the above scheme, the honeycomb skeleton connected to the side of the second carbon fiber mesh can improve the compressive strength of the plate while ensuring its lightweight nature.
[0017] Furthermore, the surface of the aluminum foil is coated with a ceramicized silicone rubber coating.
[0018] Through the above solution, the ceramicized silicone rubber coating applied to the surface of the moisture-proof and breathable aluminum foil layer is flexible at room temperature and sinterstalled into a ceramic hard shell at high temperature to prevent flame penetration.
[0019] Furthermore, fiber optic sensors are installed inside the fireproof and heat-insulating core layer and the moisture-proof and breathable layer, and a display is fixedly installed on the surface of the ceramicized silicone rubber coating.
[0020] Through the above scheme, the fiber optic sensors installed in the fireproof and heat-insulating core layer and the moisture-proof and breathable layer can monitor data such as temperature and humidity in real time, and display them intuitively on the display on the surface of the ceramicized silicone rubber coating, so as to realize intelligent management and early warning.

These layers are tightly connected to form an organic whole. The weather-resistant and impact-resistant layer contains a glass fiber reinforced concrete board, utilizing the high strength of the glass fiber and the rigidity of the concrete to give the insulation board excellent wind pressure resistance. The fire-resistant and heat-insulating core layer uses a composite of nano-aerogel and rock wool. The ultra-low thermal conductivity of the nano-aerogel effectively blocks heat transfer, while the rock wool provides reliable fire protection due to its Class A non-combustible properties.

[0029] The fire-resistant and heat-insulating composite insulation board in this embodiment is composed of a weather-resistant and impact-resistant layer 1, a fire-resistant and heat-insulating core layer 2, and a moisture-proof and breathable layer 3. The layers are tightly connected to form an organic whole. The weather-resistant and impact-resistant layer 1 is internally fitted with a glass fiber reinforced concrete board 101. The high strength of the glass fiber and the rigidity of the concrete give the insulation board excellent wind pressure resistance. The fire-resistant and heat-insulating core layer 2 is a composite of nano-aerogel 201 and rock wool 202. The ultra-low thermal conductivity of nano-aerogel 201 can effectively block heat transfer, while rock wool 202 provides reliable fire protection due to its Class A non-combustible properties. The moisture-proof and breathable layer 3 is a composite of polyvinyl alcohol film 301 and aluminum foil 302, achieving a balance between waterproofing and breathability, effectively preventing internal condensation and material moisture absorption.
[0030] The working principle of the above embodiment is as follows: First, the weather-resistant and impact-resistant layer 1 uses glass fiber reinforced concrete board 101 as its core. Glass fibers are evenly distributed in the concrete to form a three-dimensional reinforcement network. When subjected to external forces such as wind pressure and hail, the glass fibers disperse stress due to their high strength, while the concrete provides rigid support. The combination of the two gives the insulation board a strong wind pressure resistance. The photocatalytic coating 5 applied to the side of the glass fiber reinforced concrete board 101 generates electron-hole pairs under ultraviolet irradiation. This oxidizes and decomposes pollutants such as formaldehyde and nitrogen oxides in the air into harmless substances. At the same time, under the washing of rainwater, the decomposed dirt is more easily removed, achieving self-cleaning and reducing external erosion. Damage to the insulation board; the side-mounted fixing block 14 is tightly connected to the glass fiber reinforced concrete board 101 by screws 15, providing stable support for the cadmium telluride thin-film solar cell 4. After the cadmium telluride thin film absorbs light energy, the internal electrons are excited to generate electron-hole pairs. Under the action of the electric field inside the cell, the electrons and holes move to the two poles respectively, forming an electric current to generate electricity, converting solar energy into electrical energy for the building. In addition, the combination of expanded graphite 6 and magnesium hydroxide 7, when exposed to fire, the expanded graphite 6 rapidly expands to many times its original volume, forming a dense heat-insulating carbon layer, blocking heat transfer and flame spread. The magnesium hydroxide 7 decomposes when heated, absorbing a large amount of heat and releasing water vapor, reducing the surrounding temperature and further suppressing the fire. Then, the fireproof and heat-insulating core layer 2 adopts a composite structure of nano-aerogel 201 and rock wool 202. Nano-aerogel 201 has a nano-scale porous structure, and its extremely low thermal conductivity can significantly reduce the heat conduction efficiency and effectively prevent heat from being transferred by conduction. Rock wool 202 is a Class A non-combustible material. When exposed to fire, its fiber structure is stable and will not burn or melt and drip, and can directly isolate flames. The first carbon fiber mesh 8 is fixedly connected to the surface of nano-aerogel 201, and the second carbon fiber mesh 11 is connected to the surface of rock wool 202. With its high strength and high elastic modulus, the carbon fiber mesh enhances the structural stability of nano-aerogel 201 and rock wool 202, preventing the materials from deforming or breaking under temperature changes and external forces. The honeycomb skeleton 12 on the side of the second carbon fiber mesh 11, through biomimetic structural design, reduces the weight of the board while increasing the compressive strength, so that when the insulation board is under pressure, the honeycomb structure can evenly distribute stress and avoid local damage. Then, the polyvinyl alcohol film 301 in the moisture-proof and breathable layer 3 is combined with the aluminum foil 302 to form a unique moisture-proof and breathable system. The polyvinyl alcohol film 301 has hydrophilic groups and has a certain permeability to water vapor, while the aluminum foil 302 can effectively block liquid water. When the external moisture exists in the form of water vapor, it can be discharged through the microporous structure of the polyvinyl alcohol film 301. When it encounters liquid water (such as rainwater), the aluminum foil 302 acts as a barrier to prevent moisture from penetrating into the interior of the insulation board and ensure that the interior is dry. The ceramicized silicone rubber coating 13 coated on the surface of the aluminum foil 302 maintains elasticity at room temperature and does not affect the flexibility of the moisture-proof and breathable layer 3. In a high-temperature environment, the ceramicized silicone rubber quickly sinters into a ceramic-like hard shell, further enhancing the fire resistance and preventing flames from penetrating into the internal structure. Finally, the fiber optic sensor 9 installed in the fireproof and heat-insulating core layer 2 and the moisture-proof and breathable layer 3 can monitor the temperature and humidity changes inside the insulation board in real time based on the principle of light reflection and refraction. When the temperature and humidity change, it will cause the refractive index of the medium around the optical fiber to change, which will affect the propagation characteristics of light in the optical fiber. By detecting the change of light signal, temperature and humidity data can be accurately obtained. These data are transmitted through optical fiber to the display 10 on the surface of the ceramicized silicone rubber coating 13 for intuitive presentation. When the data exceeds the preset threshold (such as excessive temperature or excessive humidity), an early warning can be issued in time, which will facilitate the staff to take measures and realize the intelligent monitoring and management of the insulation board performance.
