Description

Technical Field

[0001] This utility model relates to a puncture-resistant vacuum insulation board, specifically a puncture-resistant vacuum insulation board, belonging to the field of building material technology. Background Technology

[0002] Vacuum insulation panels are a type of high-efficiency thermal insulation material, mainly composed of a core filling material, a barrier membrane, and a getter. Their working principle is to create a vacuum environment by extracting the internal air, thereby eliminating heat transfer caused by air convection and conduction.

[0003] Traditional vacuum insulation panels are easily punctured by sharp objects during actual use. For example, in building insulation projects, sharp objects such as nails and steel bars may accidentally come into contact with the insulation panels during construction. In cold chain transportation equipment, sharp tools or sharp edges of goods during handling may also puncture the insulation panels. When a vacuum insulation panel is punctured, air enters the vacuum layer inside the insulation panel, thereby destroying its vacuum environment and causing a significant decrease in the insulation performance of the panel.

[0004] To address these issues, we have developed a puncture-resistant vacuum insulation panel. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a puncture-resistant vacuum insulation panel. The specific technical solution is as follows:

[0006] A puncture-resistant vacuum insulation panel includes an insulation panel body, an anti-puncture plate is provided at the upper end of the insulation panel body, the anti-puncture plate includes a bottom plate and a top plate, a partition plate is connected between the bottom plate and the top plate, the partition plate divides the interior of the anti-puncture plate into an outer cavity and an inner cavity, the outer cavity is filled with a first component liquid, the inner cavity is filled with a second component liquid, and a partition strip connects the outer cavity and the inner cavity.

[0007] Preferably, the insulation board body includes a core material, which is a high-efficiency insulation material, such as nanoporous silica.

[0008] Preferably, a getter is uniformly connected within the core material.

[0009] Preferably, the stab-proof plate is made of a high-strength fiber-reinforced composite material, such as glass fiber reinforced plastic.

[0010] Preferably, the inner cavity is located between the outer cavity and the insulation plate body, and the first component liquid is doped with liquid pigment.

[0011] Preferably, the first component liquid and the second component liquid will produce a chemical reaction upon contact, and the two react to form a colloidal shape.

[0012] Preferably, the partition strip evenly divides the outer cavity and the inner cavity into multiple small cavities, and each small cavity does not interfere with the others.

[0013] Preferably, the heat insulation board body and the outer end of the anti-stab board are wrapped with a barrier film. The barrier film adopts a multi-layer composite structure, such as being composed of aluminum foil and a polymer film. The outer end of the barrier film is set with an anti-slip texture.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This puncture-resistant vacuum insulation panel features a puncture-resistant plate made of high-strength fiber-reinforced composite material. This plate possesses extremely high strength and hardness, effectively resisting punctures from sharp objects, thus significantly reducing the risk of punctures and extending the panel's lifespan. With its inner and outer cavities, when the puncture-resistant plate is punctured, the partition plate is penetrated, connecting the inner and outer cavities. This allows the first and second component liquids to mix, producing a chemical reaction that forms a colloid that seals the puncture hole, providing immediate repair and preventing further air ingress into the vacuum insulation panel, minimizing the decline in insulation performance.

[0016] 2. This puncture-resistant vacuum insulation panel features partition strips that evenly divide the outer and inner cavities into multiple smaller cavities. Each smaller cavity is independent of the others, so when one smaller cavity is punctured, the others remain unaffected, preventing a significant drop in overall insulation performance. This makes the vacuum insulation panel less prone to complete failure due to localized punctures, thus extending its lifespan. Whether in long-term building insulation projects or in repeatedly used transport insulation packaging, this reduces the frequency of replacements and lowers costs. Attached Figure Description

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figure 1 — Figure 5 The system includes an insulation board body 1, which includes a core material 101. The core material 101 is made of a high-efficiency insulation material, such as nanoporous silica, which has an extremely low thermal conductivity and can effectively prevent heat transfer. A getter 102 is uniformly connected inside the core material 101. The getter 102 is used to absorb any gas that may seep in and maintain the vacuum level.

[0025] The upper end of the insulation panel body 1 is provided with an anti-stab plate 2. The anti-stab plate 2 is made of high-strength fiber-reinforced composite material, such as glass fiber reinforced plastic, which has extremely high strength and hardness and can effectively resist the puncture of sharp objects from the outside, thereby greatly reducing the risk of the vacuum insulation panel being punctured and extending the service life of the vacuum insulation panel. The insulation panel body 1 and the anti-stab plate 2 are wrapped with a barrier film 3. The main function of the barrier film 3 is to form a closed space, prevent the penetration of outside air and water vapor, maintain the vacuum degree inside the core material 101, and thus maintain the insulation performance. The barrier film 3 adopts a multi-layer composite structure, such as being composed of aluminum foil and a polymer film. The aluminum foil layer can effectively block the penetration of gas molecules and maintain the internal vacuum environment. The polymer film provides flexibility and a certain tensile strength. The outer end of the barrier film 3 is set with an anti-slip texture. The anti-slip texture increases the roughness of its surface, thereby providing more contact area and allowing the film or coating material to better adhere to the surface of the vacuum insulation panel, reducing the possibility of peeling or flaking.

[0026] The stab-proof plate 2 includes a bottom plate 201 and a top plate 202. The bottom plate 201 is connected to the insulation plate body 1. A partition plate 203 connects the bottom plate 201 and the top plate 202, dividing the stab-proof plate 2 into an outer cavity 204 and an inner cavity 205. The two cavities are not connected under normal conditions. The inner cavity 205 is located between the outer cavity 204 and the insulation plate body 1. The outer cavity 204 is filled with a first component liquid 2041, which is mixed with a liquid pigment. When the top plate 202 is punctured, the first component liquid 2041 will flow out, and the color of the pigment will cause the flow to be disturbed. The liquid has a conspicuous characteristic, thus alerting construction personnel that the inner cavity 205 is filled with the second component liquid 2051. When the first component liquid 2041 comes into contact with the second component liquid 2051, a chemical reaction will occur, and the two react to form a colloid. This characteristic is a mature technology, such as: water-soluble polyurethane grouting material: this material uses water as a crosslinking agent, and it quickly solidifies and expands upon contact with water, forming a water-impermeable elastic colloid, thereby sealing cracks and blocking leakage channels; oil-based grouting liquid: this material reacts rapidly with water and expands and solidifies, forming a high expansion rate, super-structural elastic colloid, thereby achieving the purpose of sealing leaks.

[0027] A partition strip 206 connects the outer cavity 204 and the inner cavity 205. The partition strip 206 evenly divides the interior of the outer cavity 204 and the inner cavity 205 into multiple small cavities. Each small cavity does not interfere with the others. In this way, when one small cavity is punctured, the other small cavities are not disturbed, so that the overall heat insulation performance will not decrease significantly.

[0028] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
