Abstract
Description
Technical Field
[0001] The utility model belongs to the field of heat insulation materials, and in particular relates to a heat insulation protective layer based on aerogel. Background Art
[0002] Aerogel is a nanoscale porous solid material formed by the sol-gel process, whereby gas replaces the liquid phase in the gel through a specific drying method. Aerogel is currently the world's best thermal insulation material. Its thermal insulation properties can be used to create new, highly efficient thermal insulation composite materials for energy-saving buildings, offering excellent thermal insulation, fire retardancy, sound insulation, and light transmission properties.
[0003] Most existing technologies fill aerogel materials in interlayers and use the interlayers to protect the aerogel materials. However, in the construction field, especially when used outdoors or under outdoor conditions, the thermal insulation layer structure of a building will face the impact of different external environments. The structural strength of aerogel materials is relatively brittle, and the aerogel materials are easily broken and disintegrated when impacted, affecting the thermal insulation performance. Utility Model Content
[0004] The utility model provides an aerogel-based thermal insulation protective layer, which aims to solve the problem that the aerogel material protection structure of the current building thermal insulation layer structure is easily broken under external impact, affecting the thermal insulation performance of the aerogel.
[0005] The utility model is realized as follows: a heat-insulating protective layer based on aerogel, comprising:
[0006] A pressing plate layer, the pressing plate layer comprising a main pressing plate, an outer guide frame and a flexible layer; the outer guide frame is arranged on the main pressing plate, and the flexible layer is arranged inside the outer guide frame;
[0007] A base support is provided with an aerogel layer inside the base support, and a pressure-bearing column is also provided inside the base support, one end of the pressure-bearing column is connected to the base support, and the other end passes through the aerogel layer; the outer guide frame extends into the base support, and the flexible layer is supported on the end of the pressure-bearing column away from the base support.
[0008] Preferably, the aerogel layer is provided with through holes for accommodating the pressure-bearing columns to pass through.
[0009] Preferably, an inner isolation layer is further provided inside the base, and the inner isolation layer is provided between the aerogel layer and the base. The function of the inner isolation layer is to separate the base from the aerogel layer.
[0010] Preferably, the flexible layer is further provided with a accommodating limiting hole, and the limiting hole is adapted to the structure of the top surface of the pressure-bearing column.
[0011] When the outer guide frame extends into the bottom bracket, the end of the pressure column away from the bottom bracket is inserted into the limiting hole. The limiting hole is a blind hole structure to prevent the pressure column from directly contacting the main pressure plate, allowing the pressure column to become a heat transfer channel.
[0012] Preferably, the end surface of the main pressure plate away from the flexible layer is further provided with a reflective layer, and the reflective layer is a reflective heat-insulating film, which plays a long-lasting reflective and heat-insulating role on infrared heat in the solar spectrum.
[0013] Preferably, the pressure-bearing column structure is any one of a cylinder, a square column or a quadrangular pyramid.
[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:
[0015] 1. The aerogel-based thermal insulation protective layer provided by the utility model is supported by the flexible layer on the end of the pressure column away from the base. When an external impact occurs, the flexible layer will alleviate the impact force generated by the outside world. At the same time, the pressure column reduces the deformation between the base and the pressure plate layer by actively bearing pressure, thereby preventing the aerogel layer from being directly subjected to force and breaking.
[0016] 2. The aerogel-based thermal insulation protective layer provided by the utility model supports the pressure plate layer through the pressure-bearing column, so that the aerogel layer is in the accommodation area constructed by the pressure-bearing column, the pressure plate layer and the bottom support. The pressure-bearing column reduces the deformation between the bottom support and the pressure plate layer, avoiding the external impact force after deformation to cause the aerogel layer to break, thereby avoiding affecting the use effect of the aerogel layer.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0025] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0026] The present invention provides a thermal insulation layer based on aerogel. Figure 1-Figure 5 As shown, the aerogel-based thermal insulation protective layer includes:
[0027] The platen layer 100 includes a main platen 110, a reflective layer 120, an outer guide frame 130, and a flexible layer 140. The reflective layer 120 is disposed on the side of the main platen 110 facing the outdoor environment. The outer guide frame 130 is disposed on the end surface of the main platen 110 away from the reflective layer 120. The flexible layer 140 is disposed inside the outer guide frame 130.
[0028] The bottom bracket 200 is connected to the main pressure plate 110. The bottom bracket 200 is provided with an aerogel layer 400. The bottom bracket 200 is also provided with a pressure column 310. The aerogel layer 400 is provided with a through hole 410 for accommodating the pressure column 310 to pass through.
[0029] The flexible layer 140 is supported on the end of the pressure column 310 away from the base 200. When an external impact occurs, the flexible layer 140 will alleviate the impact force generated by the external environment. At the same time, the pressure column 310 reduces the deformation between the base 200 and the pressure plate layer 100 by actively bearing pressure, thereby preventing the aerogel layer 400 from being directly subjected to force and breaking.
[0030] In this embodiment, the bottom support 200 is similar to a trough-shaped structure and is mainly used to support the aerogel layer 400. The bottom support 200 can be made of impact-resistant metal material or engineering plastic alloy, and its shape is mainly used to protect the outer layer of the aerogel layer 400. The flexible layer 140 and the outer guide frame 130 extend into the bottom support 200 and are in contact with the aerogel layer 400. Here, the outer guide frame 130 is nested around the flexible layer 140. On the one hand, it protects the structural shape of the flexible layer 140. On the other hand, the outer guide frame 130 increases the connectivity between the pressure plate layer 100 and the bottom support 200, thereby avoiding misalignment between the main pressure plate 110 and the bottom support 200 due to the soft material of the flexible layer 140.
[0031] For ease of display, this application adopts a square structure as the appearance of the base 200, and its actual structure is mainly a rectangular structure. During use, it can be assembled on the wall or roof of an existing building. It is usually composed of multiple aerogel-based thermal insulation protective layers spliced together to form an overall structure, and the reflective layer 120 adopts a reflective thermal insulation film. The magnetron sputtering process is used to evenly sputter precious metals such as gold, silver, titanium, nickel, and indium onto an optical-grade PET substrate to form a multi-layer dense high-insulation metal film layer, which has a long-lasting reflective and thermal insulation effect on infrared heat in the solar spectrum.
[0032] As a preferred embodiment of this embodiment, an inner isolation layer 300 is further provided inside the base 200; the inner isolation layer 300 is provided between the aerogel layer 400 and the base 200, and the function of the inner isolation layer 300 is to separate the base 200 from the aerogel layer 400.
[0033] In this embodiment, the inner isolation layer 300 mainly serves to separate the aerogel layer 400 from the base 200. Since the base 200 made of metal generates charged particles upon heating, these charged particles float freely into the aerogel layer 400, which can affect the performance of the medium in the aerogel layer 400. Separating the aerogel layer 400 from the base 200 by the inner isolation layer 300 can reduce the impact of the charged particles.
[0034] As a preferred implementation in this embodiment, the outer guide frame 130 is nested outside the flexible layer 140. The flexible layer 140 is made of heat-insulating rubber material to meet the needs of heat insulation and shock absorption. The flexible layer 140 is also provided with a accommodating limiting hole 150. The limiting hole 150 is adapted to the structure of the top surface of the pressure-bearing column 310.
[0035] In this embodiment, the end of the pressure column 310 away from the bottom bracket is inserted into the limiting hole 150. Here, the pressure column 310 enhances connectivity with the pressure plate layer 100 with the help of the limiting hole 150, so that the aerogel layer 400 is within the accommodation area constructed by the pressure column 310, the pressure plate layer 100 and the bottom bracket 200. The pressure column 310 supports the pressure plate layer 100, thereby preventing the pressure plate layer 100 from being deformed and directly squeezing the aerogel layer 400 after external force impact; thereby reducing damage to the aerogel layer 400 and extending the thermal insulation protection time of the thermal insulation layer to the greatest extent;
[0036] It should be noted that the limiting hole 150 is a blind hole structure to prevent the pressure column 310 from directly contacting the main pressure plate 110, so that the pressure column 310 becomes a heat transfer channel, and the heat is prevented from being directly transferred to the bottom bracket 200 through the insulation of the flexible layer 140.
[0037] As a preferred implementation in this embodiment, the pressure-bearing column 310 can adopt any one of a cylindrical structure and a square column structure. The pressure-bearing column 310 can also be designed as a quadrangular pyramid structure for ease of assembly.
[0038] It should be noted that for the aforementioned embodiments, for simplicity of description, they are all expressed as a series of action combinations. However, those skilled in the art should be aware that the present invention is not limited by the order of the actions described, because according to the present invention, certain steps may be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in this specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present invention.
