Description

Technical Field

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

[0002] Vacuum insulation panels are materials used to reduce heat transfer and are widely used in construction, industrial equipment, and refrigeration. Their structure generally includes an inner insulation material (core) and an outer covering layer. The interior of the covering layer is maintained under vacuum. A patent published on September 24, 2021, with publication number CN214272448U, discloses a vacuum insulation panel. The background section explains the importance of vacuum: A vacuum prevents the penetration of external gases during the use of the vacuum insulation panel, extending its lifespan. Therefore, the covering material must possess barrier properties to prevent the penetration of common gases. It is evident that maintaining the internal vacuum and protecting the internal insulation material using the covering layer is crucial.

[0003] In the existing technology, whether the inner core is powder-pressed or plate-shaped as in the above-cited prior art, it is necessary to ensure that it maintains a normal state, protect it with a covering layer and create vacuum conditions for it, so that it can maintain its normal heat insulation function.

[0004] However, in reality, the usage and storage environments of insulation panels are often quite chaotic. A thin outer layer is insufficient to provide substantial protection for the internal insulation material. Damage such as scratches and punctures to the outer layer is frequent, especially on the two main panels which have large surfaces and are more susceptible to damage. This can disrupt the vacuum environment and even damage the main insulation material, directly impairing its insulation performance, compromising the structure, and affecting quality. Some design concepts (such as those in patent documents) involve multiple processing steps for the outer layer, applying various processes and incorporating multiple materials to improve its puncture resistance. However, this approach is too expensive, difficult to manufacture, and has high R&D and operating costs, limiting its practicality. Furthermore, whether its actual protective capability can reach the required height remains to be verified.

[0005] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, a vacuum insulation panel is specially provided to solve the technical problems of poor protective ability of the coating layer of existing vacuum insulation panels, which makes the insulation effect of the insulation panel affected. Utility Model Content

[0006] The purpose of this utility model is to provide a vacuum insulation panel to solve the technical problem that the coating layer of existing vacuum insulation panels has poor protective ability and is easily damaged, which affects the insulation effect of the insulation panel.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A vacuum insulation panel includes an inner core and a covering layer covering the outer side of the inner core. The inside of the covering layer is evacuated. The inner core is plate-shaped. A mortar coating layer is provided outside the covering layer. The mortar coating layer is uniformly coated with mortar to form a mortar layer.

[0009] The main raw material for forming the mortar layer is mortar, which is low in cost. After the mortar layer is formed, it has a certain hardness and can play a good protective role for the inner structure.

[0010] As a preferred embodiment, the slurry layer is formed by fixing a woven fabric to the outside of the coating layer.

[0011] The woven fabric is thin, inexpensive, easy to purchase, and has a good coating effect, making it a good choice for coating layers while reducing costs.

[0012] In a preferred embodiment, the grout layer is fixed outside the corresponding covering layer on the outer sides of the upper and lower surfaces of the inner core, and the mortar layer is located outside the upper and lower grout layers.

[0013] In a preferred embodiment, each of the six sides of the coating layer is covered with a grout layer, and each grout layer is coated with a mortar layer. The mortar layers on adjacent sides are connected, and the mortar layers on all sides form an integral grout layer that completely covers each grout layer.

[0014] As a preferred embodiment, the thickness of each mortar layer is the same. Here, "the same" means that the thickness is as similar as possible within a controllable range, not that it is absolutely the same.

[0015] The beneficial effects of this utility model are:

[0016] This vacuum insulation panel adds a protective structure to the existing structure. On the one hand, it can ensure that the internal structure is not damaged and maintain its normal insulation function. On the other hand, the protection is formed by mortar, which is low in cost and has low manufacturing process requirements, thus reducing the application cost and improving its practicality in actual production and use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0028] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Implementation method 1, see Figures 1-3 A vacuum insulation panel includes an inner core 1 and a covering layer 4 covering the outer side of the inner core 1. The inside of the covering layer 4 is vacuumed. The inner core 1 is plate-shaped. A mortar layer is provided outside the covering layer 4. Mortar is uniformly coated on the outside of the mortar layer to form a mortar layer 2.

[0030] The main raw material for mortar layer 2 is mortar, which is low in cost. After mortar layer 2 is formed, it has a certain hardness and can play a good protective role for the inner structure.

[0031] The slurry coating layer is formed by fixing a woven woven fabric 3 to the outside of the covering layer 4.

[0032] 3-layer woven fabric is thin, inexpensive, easy to purchase, and has a good coating effect. It is very effective as a coating layer and can reduce costs.

[0033] The grout layer is fixed outside the corresponding covering layer 4 on the outer sides of the upper and lower surfaces of the inner core 1, and the mortar layer 2 is located outside the upper and lower grout layers.

[0034] The proposed solution in this embodiment 1 involves attaching a grid cloth 3 and a mortar layer 2 to the upper and lower main surfaces, which mainly provides protection from the two large areas on the upper and lower surfaces. The process is simple as it only requires processing the upper and lower surfaces.

[0035] Implementation method 2, see Figures 4-6 The difference between this embodiment and embodiment 1 is that each of the six sides of the coating layer 4 is covered with a grouting layer, and each grouting layer is coated with a mortar layer 2. The mortar layers 2 on adjacent sides are connected, and the mortar layers 2 on all sides form an integral grouting layer that covers each grouting layer.

[0036] The thickness of each mortar layer 2 is the same. Here, "the same" means that the thickness is as similar as possible within a controllable range, not that it is absolutely the same.

[0037] This second implementation method uses a multi-faceted, full-coverage slurry coating mode, which can protect the internal structure from all directions and provide better protection.

[0038] Regardless of whether implementation method 1 or implementation method 2 is adopted, it is possible to improve the protective capability while achieving the insulation effect. The specific beneficial effects are:

[0039] This vacuum insulation panel adds a protective structure to the existing structure. On the one hand, it can ensure that the internal structure is not damaged and maintain its normal insulation function. On the other hand, the protection is formed by mortar, which is low in cost and has low manufacturing process requirements, thus reducing the application cost and improving its practicality in actual production and use.

[0040] Furthermore, due to the addition of a layered structure, the insulation effect is not only unaffected, but can also be improved to some extent.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
