Description

Technical Field

[0001] This invention belongs to the field of insulation board technology, specifically a five-constant passive house fireproof vacuum insulation board. Background Technology

[0002] With the rapid development of the green building and passive ultra-low energy building industries in China, the five-constant passive house, with its comfortable living standards of constant temperature, humidity, oxygen, quietness, and cleanliness, is gradually becoming the mainstream construction direction for high-end residences, health and wellness buildings, and public facilities. The five-constant passive house sets far stricter standards than ordinary residences for the building envelope's thermal insulation, fire safety, indoor environmental protection, moisture resistance and durability, and integrated construction support. The interior walls, ceilings, and floors all require specialized internal insulation panels to prevent thermal bridging losses, stabilize the indoor temperature and humidity environment, and ensure year-round living comfort.

[0003] Currently, traditional rock wool is widely used for exterior wall insulation. Its disadvantages include poor insulation performance, water absorption, cake formation, easy delamination, large-area detachment, and a thermal conductivity of 0.045 to 0.05. Secondly, polyurethane boards have mediocre insulation performance, are flammable, have a thermal conductivity of 0.024 to 0.028, and are prone to causing frequent exterior wall fires, resulting in significant losses of life and property. Summary of the Invention

[0004] The purpose of this invention is to provide a fireproof vacuum insulation board for five constant passive houses to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a five-constant passive house fireproof vacuum insulation board, comprising an insulation board body;

[0006] The insulation board body is a three-layer integrated composite layer structure. The middle layer is a fireproof core layer. Silicon crystal protective layers are set on both the inner and outer sides of the fireproof core layer. The two silicon crystal protective layers are cold-pressed together into a whole by an adhesive layer.

[0007] The insulation board body is divided into two types of structures: wall panels and top and bottom panels. The wall panels are vertical strip structures, with internal vertical divisions forming a sealed upper vacuum zone and a lower vacuum zone. An upper mounting plate is integrally formed between the upper and lower vacuum zones, and a lower mounting plate is integrally formed at the bottom of the lower vacuum zone and the lower end of the insulation board body. The top and bottom panels are square flat structures with sealed vacuum cavities inside. Vacuum insulation bags A and / or graphene infrared heating plates B are housed inside the vacuum cavities of the wall panels and the top and bottom panels.

[0008] As a further preferred embodiment of this technical solution, the fireproof core layer is made of aviation glass fiber knitted cotton.

[0009] As a further preferred embodiment of this technical solution, the silicon crystal protective layer is made of calcium silicate board or magnesium oxide board.

[0010] As a further preferred embodiment of this technical solution, the adhesive layer is made of zero-formaldehyde two-component polyurethane adhesive.

[0011] As a further preferred embodiment of this technical solution: the upper mounting plate is 150mm wide and is used for pre-embedding wall switches and low-voltage sockets; the lower mounting plate is 350mm wide and is used for pre-embedding five-hole sockets, floor sockets, and high-power electrical components.

[0012] As a further preferred embodiment of this technical solution: after assembling the vacuum insulation bag A inside the vacuum cavity, the thermal conductivity of the finished insulation board is 0.0020.

[0013] As a further preferred embodiment of this technical solution: the top and bottom plates are provided with a three-layer composite structure consisting of a fireproof core layer, a silicon crystal protective layer, and an adhesive layer, as well as a built-in sealed vacuum cavity.

[0014] As a further preferred embodiment of this technical solution, the insulation board body structure is prefabricated in a factory in an integrated manner.

[0015] As a further preferred embodiment of this technical solution: the upper vacuum zone, lower vacuum zone of the wall panel, and the internal vacuum cavity of the top and bottom plates are all completely sealed vacuum cavities.

[0016] As a further preferred embodiment of this technical solution: a vacuum insulation bag A is placed inside the vacuum cavity to form a heat-insulating plate; a graphene infrared heating plate B is placed inside the vacuum cavity to form a heating plate; a vacuum insulation bag A and a graphene infrared heating plate B are placed inside the vacuum cavity to form a heat-insulating and heating composite plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the insulation board is integrally formed by three layers: a fireproof core layer, a silicon crystal protective layer, and an adhesive layer. The fireproof core layer uses aviation fiberglass knitted cotton, and the silicon crystal protective layer uses calcium silicate board or magnesium oxide board. The whole board meets the Class A non-combustible standard and is smokeless, fireless, and odorless at a high temperature of 1000 degrees Celsius. The adhesive layer uses zero-formaldehyde two-component polyurethane adhesive, which does not release harmful substances into the room. At the same time, the adhesive layer has water-repellent and mildew-proof properties, which can prevent moisture from penetrating into the interior of the board. Long-term use will not cause delamination, mold, water absorption and deformation problems, and completely solves the defects of traditional rock wool and organic polyurethane insulation boards, such as flammability, water absorption and shedding, and pollution of the indoor environment.

[0019] 2. In this invention, the wall panel is equipped with a completely sealed segmented vacuum chamber, and the top and bottom panels have an integrated sealed vacuum chamber. The vacuum chamber can be equipped with a vacuum insulation bag A, a graphene infrared heating plate B, or both components simultaneously. When only the vacuum insulation bag A is installed, the thermal conductivity of the panel is as low as 0.0020, which significantly blocks thermal bridges in the building, reduces indoor heat loss, and lowers the energy consumption of air conditioning and heating equipment. When combined with the graphene infrared heating plate B, low-temperature heating can be achieved. The simultaneous installation of the two can take into account both heat insulation and heating. One set of panels can meet the combined needs of heat insulation in the south, heating in the north, and heat insulation and heating in extremely cold regions, making it applicable to a wider range of scenarios.

[0020] 3. In this invention, the wall panel has an integrally formed upper mounting plate with a width of 150mm between the segmented vacuum cavities, and an integrally formed lower mounting plate with a width of 350mm at the bottom. The upper and lower mounting plates are solid, cavity-free structures of the same material as the fireproof core layer, allowing for direct slotting and pre-embedding of electrical components such as switches, sockets, and floor plugs. Slotting does not damage the sealed heat insulation structure of the vacuum cavity, eliminating the need for additional pre-embedded boxes. The top and bottom panels have no pre-embedded structures and can be directly laid flat on the top surface and the bottom of the floor slab. Both types of panels are prefabricated integrated finished products in the factory, requiring only splicing and assembly on site, significantly shortening the decoration period and reducing on-site construction procedures and construction waste.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Please see Figures 1-5 As shown, the present invention provides a technical solution: a five-constant passive house fireproof vacuum insulation board.

[0031] Example 1:

[0032] In this embodiment, the wall-type vacuum insulation board is a vertical strip-shaped internal wall insulation board. The main component is the insulation board body 1. The insulation board body 1 is a three-layer structure consisting of a fireproof core layer 11, a silicon crystal protective layer 12, and an adhesive layer 13, which are integrated and cold-pressed into a composite form.

[0033] Furthermore, the fireproof core layer 11 is made of aviation fiberglass knitted cotton, and the entire board meets the Class A non-combustible standard. It produces no smoke, open flame, or irritating odor when burned at 1000℃. The inner and outer sides of the fireproof core layer 11 are respectively bonded with a silicon crystal protective layer 12 made of calcium silicate board or magnesium oxide board. The thickness of the silicon crystal protective layer 12 is 3mm-5mm. The fireproof core layer 11 and the silicon crystal protective layer 12 are bonded and fixed together by an adhesive layer 13 made of zero-formaldehyde two-component polyurethane adhesive.

[0034] In this embodiment, the insulation board body 1 is provided with partition ribs to form two independent sealed cavities, namely the upper vacuum zone 2 and the lower vacuum zone 3; the solid area between the upper vacuum zone 2 and the lower vacuum zone 3 is the upper mounting plate 4, which is 150mm wide and can be directly grooved to pre-embed wall switches and low-voltage sockets; the solid area at the bottom of the lower vacuum zone 3 is the lower mounting plate 5, which is 350mm wide and can be grooved to install five-hole sockets, floor sockets, and smart home junction boxes. The grooving operation will not damage the airtightness of the cavity. The upper mounting plate 4 and the lower mounting plate 5 are both made of aviation glass fiber knitted cotton.

[0035] Among them, the upper vacuum zone 2 and the lower vacuum zone 3 are both completely sealed vacuum cavities. The internal functional components are assembled in three ways: the first is to only install the vacuum insulation bag A, which is made of aluminum foil with a thickness of 10mm-25mm; the finished board has a thermal conductivity of 0.0020; the second is to only install the graphene infrared heating plate B, which has a low-temperature heating function; the third is to simultaneously install the vacuum insulation bag A and the graphene infrared heating plate B, which has both ultra-low thermal conductivity insulation performance and heating function.

[0036] In this embodiment, Figure 4 Vacuum insulation bag A is made of aluminum foil with a thickness of 10mm-25mm. Its function is highly efficient thermal insulation, with a thermal conductivity as low as 0.0020. In contrast, conventional rock wool has a thermal conductivity of only 0.045-0.05, and polyurethane insulation boards have a thermal conductivity of 0.028, showing a significant difference in thermal conductivity. Furthermore, the integrated process of combining the composite vacuum cavity with vacuum insulation bag A in this embodiment can simultaneously meet the core requirements of passive houses in terms of thermal insulation, livability, energy saving, and environmental protection, integrating multiple functions such as Class A fire resistance, vacuum insulation, zero formaldehyde, waterproofing, mildew resistance, and sound insulation.

[0037] Furthermore, Figure 5 The graphene infrared heating panel B is an integrally embedded component within the panel. It provides warmth through far-infrared heating, transferring heat from the ground to the human body. This aligns with the therapeutic concept of warming the feet and cooling the head. The heating temperature is stably controlled within the range of 35℃ to 45℃. Power supply options include direct 220V supply or a transformer-stepped voltage of 36V for safety. After installation, there is no need for additional radiators or traditional underfloor heating. It boasts advantages such as low initial investment, no maintenance required, extremely low energy consumption, and clean, safe, and pollution-free operation.

[0038] In this embodiment, all structures of the entire panel are prefabricated and integrated in the factory. After the raw materials are cut, they are glued and cold-pressed to obtain the basic composite substrate. Then, the cavity partition ribs and the solid structure of the mounting plate are processed. After filling the corresponding functional components, the cavity is sealed. The panel is transported to the construction site and directly attached to the wall for splicing and fixing. Electrical components are only installed in the grooves in the upper mounting plate 4 and the lower mounting plate 5.

[0039] Example 2:

[0040] In this embodiment, the top and bottom plate type vacuum insulation board is a square flat plate structure, which is suitable for laying on the roof and bottom of the floor of passive house. The basic composite structure is consistent with the wall panel, including the insulation board body 1, fireproof core layer 11, silicon crystal protective layer 12, and adhesive layer 13. The fireproof core layer 11, silicon crystal protective layer 12, and adhesive layer 13 are made of the same materials as the wall panel. The thickness of silicon crystal protective layer 12 is controlled to be 3mm-5mm. The three-layer structure is pre-cooled and pressed in the factory.

[0041] Furthermore, the top and bottom plates have a three-layer composite structure consisting of a fireproof core layer 11, a silicon crystal protective layer 12, and an adhesive layer 13, and an integrated built-in sealed vacuum chamber. There are no upper or lower mounting plates, nor is a segmented chamber layout. The vacuum chamber inside the top and bottom plates is completely sealed and supports three assembly methods: only assembling the vacuum insulation bag A, only assembling the graphene infrared heating plate B, and simultaneously assembling both the vacuum insulation bag A and the graphene infrared heating plate B. The vacuum insulation bag A is made of aluminum foil with a thickness of 10mm-25mm. After assembling the vacuum insulation bag A, the thermal conductivity of the plate is also 0.0020.

[0042] In this embodiment, the performance, function, and advantages of the vacuum insulation bag A and graphene infrared heating plate B used are completely consistent with those of Embodiment 1. The vacuum insulation bag achieves ultra-low thermal conductivity and energy-saving insulation, while the graphene infrared heating plate achieves far-infrared therapy-style low-temperature heating. The two can be assembled individually or in combination, allowing the top and bottom panels to also have the comprehensive characteristics of Class A fire resistance, vacuum insulation, zero formaldehyde, waterproof and mildew-proof, and sound insulation, making them suitable for the five constant insulation and heating requirements of the entire roof and the bottom of the floor slab.

[0043] In this embodiment, the top and bottom plates are uniformly cut into standard square sizes, eliminating the need for processing segmented cavities and electrical embedded solid plates. After integrated prefabrication, they are directly transported to the site and laid flat on the top surface and bottom of the floor slab. There is no need to cut grooves to embed electrical components, and they are combined with the wall panels to form a complete internal insulation system for the whole house.

[0044] Working principle or structural principle: The whole relies on the synergistic effect of three-layer inorganic composite fireproof substrate and sealed vacuum cavity to achieve integrated fireproof, heat preservation and heating effect. The board is divided into two types of prefabricated components, wall board and top and bottom board, to build the whole house indoor and outdoor heat preservation system. The insulation board body 1 has a fireproof core layer 11 made of aviation glass fiber knitted cotton as the middle main body, and the inner and outer sides are respectively bonded with a silicon crystal protective layer 12 made of calcium silicate board or glass magnesium board. The three-layer structure is formed by cold pressing and curing a bonding layer 13 made of zero formaldehyde two-component polyurethane adhesive to form a complete integrated substrate. The fireproof core layer 11 and silicon crystal protective layer 12 are both inorganic non-combustible materials. They have no open flame, no smoke and no irritating odor in a high temperature environment of 1000℃, achieving the basic fireproof performance of Class A of the board. The bonding layer 13 has water-repellent and mildew-proof properties, which can prevent water vapor from penetrating into the interior of the board, prevent the board from getting damp and delaminating, and prevent the growth of mold, ensuring the long-term stability of the board structure.

[0045] The wall panel is equipped with two independent and completely sealed upper vacuum zone 2 and lower vacuum zone 3. The top and bottom panels are equipped with an integrated, completely sealed vacuum chamber. After the air is removed from the vacuum chamber, the channels for air heat conduction and heat convection are eliminated. The chamber can be filled with a vacuum insulation bag A, a graphene infrared heating plate B, or both vacuum insulation bag A and graphene infrared heating plate B simultaneously. When vacuum insulation bag A is filled, heat exchange can be further reduced, so that the thermal conductivity of the finished panel reaches 0.0020, which effectively blocks the cold and heat bridges of the building walls, ceiling, and floor, reduces the loss of indoor cold and heat energy and reduces the energy consumption of air conditioning and heating equipment. When graphene infrared heating plate B is installed alone, the heating plate releases low-temperature heat when energized, and the vacuum chamber can prevent heat from escaping outward to achieve uniform indoor heating. When the two components are installed simultaneously, they have both ultra-low thermal conductivity insulation and stable heating capabilities, which can meet the needs of different climate regions.

[0046] The wall panel has an integrally formed upper mounting plate 4 with a width of 150mm between the upper vacuum zone 2 and the lower vacuum zone 3, and an integrally formed lower mounting plate 5 with a width of 350mm at the bottom. The upper mounting plate 4 and the lower mounting plate 5 are made of the same material as the fireproof core layer 11 and are solid without cavities. Various switches, sockets and junction boxes can be directly embedded by grooving. The grooving operation will not damage the sealed heat insulation structure of the upper vacuum zone 2 and the lower vacuum zone 3, realizing the integrated construction of heat insulation and electrical embedding. The top and bottom plates are solid plates without segmented vacuum zones and electrical embedding, and are directly laid flat on the roof and the bottom of the floor slab, forming a complete heat insulation closed loop for the whole house in conjunction with the wall panel.
