Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel technology, specifically a vacuum insulation panel with improved surface strength. Background Technology

[0002] Vacuum insulation panels are a type of vacuum insulation material, composed of a core filler and a protective surface layer, vacuum-sealed together. This effectively prevents heat transfer caused by air convection, thus significantly reducing its thermal conductivity. Vacuum insulation panels contain no ODS (Oxygen Dessert) materials, making them environmentally friendly and energy-efficient. They are currently the world's most advanced high-efficiency insulation material and are widely used in the refrigeration, freezing, and insulation industries.

[0003] Some existing vacuum insulation panels have brittle surfaces. For example, vacuum insulation panels made with phenolic foam cores are prone to surface dents when pressure is applied during use, and these dents are irreversible. The brittle surface of these panels inevitably leads to pressure being applied during transportation or use, causing dents and thus affecting their application.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vacuum insulation panel with improved surface strength. By setting reinforcing layers on the upper and lower surfaces of the core material, the resulting vacuum insulation panel has high surface strength and is less prone to surface dents during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vacuum insulation panel with improved surface strength includes a membrane material, a core material, a first reinforcing layer, a second reinforcing layer, and an adsorbent.

[0008] A vacuum cavity is formed within the membrane material; the core material is disposed within the vacuum cavity; the first reinforcing layer is disposed within the vacuum cavity and is located on one surface of the core material; the second reinforcing layer is disposed within the vacuum cavity and is located on the other surface of the core material; the adsorbent is disposed within the vacuum cavity.

[0009] Furthermore, the membrane material includes an upper barrier membrane and a lower barrier membrane, and the edges of the upper barrier membrane and the lower barrier membrane are heat-sealed together.

[0010] Furthermore, the core material is a brittle foam-type core material.

[0011] Furthermore, the core material is phenolic foam core material.

[0012] Furthermore, the first reinforcing layer has a thickness of 0.05mm-2mm, and the second reinforcing layer has a thickness of 0.05mm-2mm.

[0013] Furthermore, the first reinforcing layer and the second reinforcing layer are made of non-metallic materials or metallic materials.

[0014] Furthermore, the first and second reinforcing layers are made of PET, PP, PE, PS, PA, or PTFE materials; or, the first and second reinforcing layers are made of glass fiber mat, glass fiber cement coated mat (also known as cement mortar paper), or glass fiber cloth.

[0015] Furthermore, the first and second reinforcing layers are stainless steel foil, galvanized steel foil, nickel-plated steel foil, or aluminum sheets.

[0016] Furthermore, it also includes a first protective layer and a second protective layer, wherein the first protective layer is disposed on one surface of the membrane material and the second protective layer is disposed on the other surface of the membrane material.

[0017] Furthermore, the first protective layer and the second protective layer are made of PET, PP, PE or PS materials.

[0018] Furthermore, it also includes a side protective layer, which is disposed on the outer side of the membrane material.

[0019] This invention provides a vacuum insulation panel with improved surface strength. It offers the following advantages: because the first reinforcing layer is located on one surface of the core material and the second reinforcing layer is located on the other surface of the core material, the first and second reinforcing layers sandwich the core material, thus protecting it. During use or transportation, the protective effect of the first and second reinforcing layers results in high surface strength, making the surface of the vacuum insulation panel less prone to dents during use.

[0021] Figure 2 This is a cross-sectional view of a vacuum insulation panel for improving surface strength in another embodiment of this application.

[0022] The membrane material includes 1, an upper barrier membrane 11, a lower barrier membrane 12, a core material 2, a first reinforcing layer 3, a second reinforcing layer 4, an adsorbent 5, a first protective layer 6, a second protective layer 7, and a side protective layer 8. Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1 and Figure 2 As shown, a vacuum insulation panel for improving surface strength according to this utility model includes a membrane material 1, a core material 2, a first reinforcing layer 3, a second reinforcing layer 4, and an adsorbent 5; a vacuum cavity is formed inside the membrane material 1; the core material 2 is disposed in the vacuum cavity; the first reinforcing layer 3 is disposed in the vacuum cavity and is located on one surface of the core material 2; the second reinforcing layer 4 is disposed in the vacuum cavity and is located on the other surface of the core material 2; and the adsorbent 5 is disposed in the vacuum cavity.

[0025] Thus, the vacuum insulation panel with improved surface strength according to this utility model has a first reinforcing layer 3 located on one surface of the core material 2 and a second reinforcing layer 4 located on the other surface of the core material 2, which sandwiches the core material 2, thereby protecting it. During use or transportation, the protective effect of the first reinforcing layer 3 and the second reinforcing layer 4 results in high surface strength of the vacuum insulation panel, making it less prone to surface dents during use.

[0026] In this embodiment, the membrane material 1 includes an upper barrier membrane 11 and a lower barrier membrane 12, with the edges of the upper barrier membrane 11 and the lower barrier membrane 12 heat-sealed together. During manufacturing, the upper barrier membrane 11 and the lower barrier membrane 12 are first heat-sealed on three sides to form a barrier bag with an opening. After the core material 2, the first reinforcing layer 3, the second reinforcing layer 4, and the adsorbent 5 are packed into the bag, the opening is then vacuum-sealed to form a vacuum insulation board.

[0027] In this embodiment, the core material 2 is a brittle foam core material, such as phenolic foam core material. Vacuum insulation panels made with phenolic foam core material are very lightweight and have good flame-retardant properties. Since phenolic foam core material is relatively brittle, by providing a first reinforcing layer 3 and a second reinforcing layer 4 on the surface of the phenolic foam core material, the phenolic foam core material can be effectively protected, making it less likely for the surface of the vacuum insulation panel to dent during use.

[0028] In this embodiment, the first reinforcing layer 3 has a thickness of 0.05mm-2mm, and the second reinforcing layer 4 has a thickness of 0.05mm-2mm.

[0029] The first reinforcing layer 3 and the second reinforcing layer 4 are materials that are not easily released in a vacuum. The first reinforcing layer 3 and the second reinforcing layer 4 are non-metallic or metallic materials. The thickness of some metallic materials can be 0.05mm-0.5mm, and the thickness of some non-metallic materials can be 0.2mm-2mm. The first reinforcing layer 3 and the second reinforcing layer 4 are placed on the upper and lower surfaces of the core material 2 after being dried to remove moisture.

[0030] Specifically, the first reinforcing layer 3 and the second reinforcing layer 4 of the non-metallic materials are made of PET, PP, PE, PS, PA, or PTFE; the first reinforcing layer 3 and the second reinforcing layer 4 are glass fiber mat, glass fiber cement coated mat (also known as cement mortar paper), or glass fiber cloth. The first reinforcing layer 3 and the second reinforcing layer 4 of the metallic materials are stainless steel foil, galvanized steel foil, nickel-plated steel foil, or aluminum sheet. The edges of the metallic materials are passivated and placed on the upper and lower surfaces of the core material 2 to prevent the metallic materials from damaging the membrane material 1.

[0031] After testing, the first reinforcing layer 3 and the second reinforcing layer 4 made of these materials, with a thickness of 0.05mm-2mm, both have a certain degree of hardness and toughness. When they are in close contact with the core material 2, they can disperse the large pressure locally borne on the surface of the core material 2, maintain the internal skeleton structure of the core material 2 from being damaged, and thus can better protect the core material 2.

[0032] like Figure 2 As shown, in a preferred embodiment of this utility model, a first protective layer 6 and a second protective layer 7 are further included. The first protective layer 6 is disposed on one surface of the membrane material 1, and the second protective layer 7 is disposed on the other surface of the membrane material 1. The first protective layer 6 and the second protective layer 7 are made of PET, PP, PE, or PS materials.

[0033] By setting the first protective layer 6 and the second protective layer 7, the surface strength of the vacuum insulation panel is further improved. Since the first protective layer 6 and the second protective layer 7 are set on the upper and lower surfaces of the membrane material 1, the membrane material 1 can be effectively protected, making the membrane material 1 less prone to damage, thereby improving the service life of the vacuum insulation panel.

[0034] In this embodiment, a side protective layer 8 is also included. The side protective layer 8 is disposed on the outer side of the membrane material 1. By providing the side protective layer 8, the strength of the side of the vacuum insulation panel can be improved.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
