Meanwhile, the whole heat insulation plate can be attached to the surface of a needed object in the later period by means of the characteristic that the heat insulation plate can deform.

And the whole shaped microporous fire-resistant heat-insulating plate can be bent around one side of the opening groove by utilizing the vacuum blocking layer which covers the outer side of the microporous fire-resistant heat-insulating plate and the vacuum state of the interior of the microporous fire-resistant heat-insulating plate and cooperating with the deformation force of the vacuum blocking layer, so that the shaped microporous fire-resistant heat-insulating plate is attached to the surface of an object. And the vacuum barrier layer can also play roles in protecting the microporous fire-resistant heat insulation plate and reducing heat transfer, so that three purposes are achieved.

Description

Technical Field

[0001] This utility model relates to the field of heat insulation board technology, and in particular to a multi-groove structure heat insulation board. Background Technology

[0002] Currently, thermal insulation panels are generally manufactured using high-pressure roll forming, resulting in a flat shape. When attaching such panels to curved surfaces with small radii of curvature, the panels are simply bent and adhered to the surface. However, when attaching them to curved surfaces with large radii of curvature, the material limitations prevent excessive bending. Forcing bending can cause breakage, and the panels cannot adhere tightly to the curved surface, reducing insulation effectiveness. To address this, the panels are typically cut into strips, and the sides of these strips are beveled. Multiple strips are then joined together to form a composite insulation structure that fits the curved surface. This assembly method is cumbersome, complex, and costly. Utility Model Content

[0003] To achieve the above objectives, this utility model provides a multi-groove structure heat insulation board, comprising:

[0004] A microporous fire-resistant insulation board has several openings on one side, and the microporous fire-resistant insulation board can be bent and deformed into a cylindrical or C-shaped shape along the side with the openings.

[0005] A vacuum barrier layer is wrapped around the outside of the microporous fire-resistant insulation board. The vacuum barrier layer is in a vacuum state and is deformable.

[0006] In some possible implementations, the microporous refractory insulation board is formed by pressing inorganic non-metallic oxides, inorganic additives and inorganic fibers after high-speed mixing.

[0007] In some possible implementations, the vacuum barrier layer is made of PE or EVA material.

[0008] In some possible implementations, the vacuum barrier layer is made of one or two of PE, PE composite NY, PE composite PET, PE composite VMPET, PE composite PET\NY, PE composite VMPET\NY, or PE composite AL\VMPET\NY.

[0009] In some possible implementations, the vacuum barrier layer is made of one or two of EVA, EVA composite NY, EVA composite PET, EVA composite VMPET, EVA composite PET\NY, EVA composite VMPET\NY, or EVA composite AL\VMPET\NY.

[0010] In some possible implementations, the vacuum barrier layer has a thickened shaping portion on the back side of the microporous refractory insulation board on the side where the opening groove is provided.

[0011] In some possible implementations, the thickened shaping section is provided with steel wire or a shaped bending element.

[0012] In some possible implementations, the opening depth of the slot is greater than half the thickness of the microporous fire-resistant insulation board.

[0013] In some possible implementations, the opening slot is V-shaped or U-shaped.

[0014] In some possible implementations, the vacuum barrier layer is provided with a protective layer on the side of the microporous refractory insulation board that is not provided with the opening slot.

[0015] Compared to existing technologies, the advantages of this invention are as follows: The multi-groove structure insulation board of this invention uses a microporous fire-resistant insulation board as the insulation core. This effectively utilizes its microporous structure to reduce the weight of the entire board, while its deformable properties allow the entire insulation board to be adhered to the desired object surface. By opening several grooves on one side of the microporous fire-resistant insulation board, workers can easily bend it according to actual usage. The groove design improves bending convenience and prevents breakage during bending. Furthermore, a vacuum barrier layer is used to cover the outside of the microporous fire-resistant insulation board, effectively shaping it. The internal vacuum state and the deformation force of the vacuum barrier layer allow the shaped microporous fire-resistant insulation board to bend around one side of the grooves, ensuring it adheres to the object surface. In addition, the vacuum barrier layer also protects the microporous fire-resistant insulation board and reduces heat transfer, achieving three benefits in one step. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0022] Reference Figures 1 to 3 The multi-groove structure insulation board shown includes a microporous fire-resistant insulation board 10 and a vacuum barrier layer 20. The microporous fire-resistant insulation board 10 has several open grooves 11 on one side. The microporous fire-resistant insulation board 10 can be bent and deformed into a cylindrical or C-shaped shape along the side with the open grooves 11. The vacuum barrier layer 20 covers the outside of the microporous fire-resistant insulation board 10. The vacuum barrier layer 20 is in a vacuum state and can be deformed.

[0023] In this invention, the microporous fire-resistant insulation board 10 can be a conventional insulation board, while the vacuum barrier layer 20 can be a traditional insulation membrane structure. The width of the opening groove 11 needs to be determined based on actual usage requirements. In practical applications, the larger the radius of curvature of the object's arc surface, the larger the width and depth of the opening groove 11, and vice versa.

[0024] This multi-groove structure insulation panel uses a microporous fire-resistant insulation board 10 as the insulation core. This effectively utilizes its microporous structure to reduce the weight of the entire panel, while its deformable properties allow the entire insulation panel to be adhered to the desired object surface. Several openings 11 are formed on one side of the microporous fire-resistant insulation board 10, facilitating bending by workers according to actual usage. The openings 11 design improves bending convenience and prevents breakage of the microporous fire-resistant insulation board 10 during bending. A vacuum barrier layer 20 is then used to cover the outside of the microporous fire-resistant insulation board 10, effectively shaping it. Utilizing the internal vacuum state and the deformation force of the vacuum barrier layer 20, the shaped microporous fire-resistant insulation board 10 can be bent around one side of the openings 11, allowing it to adhere to the object surface. Furthermore, the vacuum barrier layer 20 also protects the microporous fire-resistant insulation board 10 and reduces heat transfer, achieving three benefits in one step.

[0025] In some possible implementations, the microporous fire-resistant insulation board 10 is formed by high-speed mixing and pressing of inorganic non-metallic oxides, inorganic additives, and inorganic fibers. The inorganic non-metallic oxides can be silicon dioxide, titanium dioxide, fumed alumina, etc., while the inorganic additives can be adhesives or flame-retardant and heat-insulating materials, such as silicon carbide, carbon black, zirconium silicate, zirconium oxide, etc., and the inorganic fibers can be conventional glass fiber, carbon fiber, aluminosilicate fiber, ceramic fiber, basalt fiber, high-silica fiber, quartz fiber, alumina fiber, etc.

[0026] Furthermore, in some embodiments, to facilitate bending of the microporous refractory insulation board 10, the depth of the opening groove 11 is greater than half the thickness of the microporous refractory insulation board 10. Simultaneously, the opening groove 11 is V-shaped or U-shaped.

[0027] In some possible implementations, the vacuum barrier layer 20 in this application is made of PE or EVA material due to its certain vacuum barrier properties.

[0028] More specifically, the vacuum barrier layer 20 is made of one or two of PE, PE composite NY, PE composite PET, PE composite VMPET, PE composite PET\NY, PE composite VMPET\NY, or PE composite AL\VMPET\NY.

[0029] In another embodiment of this application, the vacuum barrier layer 20 is made of one or two of EVA, EVA composite NY, EVA composite PET, EVA composite VMPET, EVA composite PET / NY, EVA composite VMPET / NY, or EVA composite AL / VMPET / NY.

[0030] See Figure 3 The vacuum barrier layer 20 has a thickened shaping portion 21 on the back side of the microporous refractory insulation board 10, on the side with the opening groove 11. The main purpose of the thickened shaping portion 21 is to prevent the outer surface of the vacuum barrier layer 20 from breaking, and to enhance the strength of the entire outer surface of the vacuum barrier layer 20, thereby improving its protective capability. Therefore, in the improved embodiment described above, the thickened shaping portion 21 contains a steel wire or a shaped bending component. The steel wire can be a high-strength steel wire with pre-stress, and the shaped bending component can be a conventional slat structure or a rigid plastic part.

[0031] In some possible implementations, to enhance protection, the vacuum barrier layer 20 is provided with a protective layer 22 on the side of the microporous fire-resistant insulation board 10 that is not provided with the opening groove 11. The protective layer 22 is a conventional protective paint layer or an aluminum foil film.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
