Description

Technical Field

[0001] This utility model relates to the field of thermal insulation cotton technology, and in particular to an aerogel thermal insulation cotton. Background Technology

[0002] Aerogel insulation cotton is a flexible insulation material made of nano-aerogel as the main material and composite with fiber materials. As a highly efficient insulation material, aerogel insulation cotton has been widely used in construction, aerospace, transportation and other fields.

[0003] However, existing aerogel thermal insulation cotton has some shortcomings in actual use. Due to the limited strength and stability of the aerogel thermal insulation cotton itself, it is prone to "cotton leakage", which affects its thermal insulation effect and service life. In addition, the surface of aerogel thermal insulation cotton is easily damaged by external forces such as friction and scratches during use, which reduces its protective performance. Therefore, we propose an aerogel thermal insulation cotton to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the limited strength and stability of the gel insulation cotton itself, the tendency for "cotton slippage" to occur, and the susceptibility of its surface to damage from external forces such as friction and scratches, which reduces its protective performance. Therefore, this invention proposes an aerogel thermal insulation cotton.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aerogel thermal insulation cotton includes an aerogel thermal insulation cotton body. A mesh layer is provided at both the top and bottom of the aerogel thermal insulation cotton body. The mesh layer is used to improve the overall strength and stability of the aerogel thermal insulation cotton body. A scratch-resistant and abrasion-resistant protective structure is provided on the top of the mesh layer at the top of the aerogel thermal insulation cotton body. A contact structure is provided on the bottom of the mesh layer at the bottom of the aerogel thermal insulation cotton body. The protective structure includes an abrasion-resistant layer, which is bonded to the top of the mesh layer at the top of the aerogel thermal insulation cotton body. The contact structure includes a thermal insulation layer, which is bonded to the bottom of the mesh layer at the bottom of the aerogel thermal insulation cotton body.

[0007] In one possible design, both of the mesh layers are made of glass fiber, which is insulating and corrosion resistant.

[0008] In one possible design, a fireproof layer is provided between the wear-resistant layer and the mesh layer located on top of the aerogel insulation cotton body, the top of the fireproof layer and the bottom of the wear-resistant layer are bonded together, and the bottom of the fireproof layer is bonded to the mesh layer located on top of the aerogel insulation cotton body.

[0009] In one possible design, the wear-resistant layer is made of waterproof polyurethane, and the fireproof layer is made of glass wool with heat insulation and fireproof properties.

[0010] In one possible design, the insulation layer is made of quartz fiber, which has high temperature resistance and stability.

[0011] In one possible design, aluminum foil is adhered to the bottom of the insulation layer.

[0012] In this application, firstly, the aerogel thermal insulation cotton includes an aerogel thermal insulation cotton body, a protective structure, a contact structure, two mesh layers, etc., wherein the two mesh layers are respectively disposed at the top and bottom of the aerogel thermal insulation cotton body, the protective structure is disposed at the top of the mesh layer located at the top of the aerogel thermal insulation cotton body, and the contact structure is disposed at the bottom of the mesh layer located at the bottom of the aerogel thermal insulation cotton body.

[0013] The mesh layer is made of glass fiber, which has good insulation, corrosion resistance and fire resistance and is relatively inexpensive, effectively improving the overall strength and stability of the aerogel insulation cotton; the mesh layer can also prevent the aerogel insulation cotton from "running away" during use.

[0014] The protective structure includes a wear-resistant layer made of waterproof polyurethane. The wear-resistant layer is bonded to the top of the mesh layer located on top of the aerogel insulation cotton body, which effectively enhances the scratch and wear resistance of the aerogel insulation cotton. In addition, a fireproof layer is set between the wear-resistant layer and the mesh layer and is made of glass wool with heat insulation and fireproof properties, which further improves the fire resistance of the product.

[0015] The contact structure includes a heat insulation layer made of quartz fiber with high temperature resistance and stability. The heat insulation layer is bonded to the bottom of the mesh layer located at the bottom of the aerogel insulation cotton body, which effectively improves the heat insulation effect of the aerogel insulation cotton. In addition, aluminum foil is also bonded to the bottom of the heat insulation layer, which further improves the heat insulation effect and reduces heat transfer.

[0016] Beneficial effects: In this utility model, the aerogel thermal insulation cotton is provided with a mesh layer at both the top and bottom of the aerogel thermal insulation cotton body, which effectively improves the overall strength and stability of the aerogel thermal insulation cotton and prevents the occurrence of "cotton running away".

[0017] In this utility model, the aerogel thermal insulation cotton, through the setting of a protective structure, effectively enhances the scratch and abrasion resistance of the aerogel thermal insulation cotton and extends its service life.

[0018] In this utility model, the aerogel thermal insulation cotton, through the addition of an insulation layer, further improves the thermal insulation effect of the aerogel thermal insulation cotton, reduces heat transfer, and improves thermal insulation performance.

[0019] In this invention, the mesh layer effectively improves the overall strength and stability of the aerogel insulation cotton, preventing the "cotton slippage" phenomenon. The protective structure effectively enhances the scratch and abrasion resistance of the aerogel insulation cotton, extending its service life. The insulation layer further improves the insulation effect of the aerogel insulation cotton, reduces heat transfer, and improves its insulation performance. Attached Figure Description

[0024] 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.

[0025] Example 1: Refer to Figure 1-3 A type of thermal insulation cotton includes an aerogel thermal insulation cotton body 1. To improve the overall strength and stability of the aerogel thermal insulation cotton body 1 and prevent "cotton slippage," a mesh layer 2 is provided at both the top and bottom of the aerogel thermal insulation cotton body 1. These two mesh layers 2 are made of glass fiber, which has good insulation, corrosion resistance, and fire resistance, and is relatively inexpensive, ensuring the stability and durability of the thermal insulation cotton in various environments.

[0026] A scratch- and abrasion-resistant protective structure 3 is provided on top of the mesh layer 2 located at the top of the aerogel insulation body. This protective structure 3 specifically includes an abrasion-resistant layer 5, which is made of waterproof polyurethane. This material choice allows the abrasion-resistant layer 5 to effectively resist external scratches and abrasion while maintaining its waterproof performance, thus extending the service life of the insulation.

[0027] A fireproof layer 6 is also provided between the wear-resistant layer 5 and the mesh layer 2 located on top of the aerogel insulation cotton body. The fireproof layer 6 is made of glass wool with heat insulation and fire resistance properties. The fireproof layer 6 further enhances the fire resistance of the insulation cotton, enabling it to maintain structural integrity and heat insulation effect even in high-temperature environments. The top of the fireproof layer 6 is bonded to the bottom of the wear-resistant layer 5, and the bottom is bonded to the mesh layer 2 located on top of the aerogel insulation cotton body, forming a stable multi-layer structure.

[0028] A contact structure 4 is provided at the bottom of the mesh layer 2 at the bottom of the aerogel insulation cotton body. This contact structure 4 includes an insulation layer 7, which is made of quartz fiber with high temperature resistance and stability. This material selection allows the insulation layer 7 to effectively block heat transfer, further improving the thermal insulation effect of the insulation cotton. The insulation layer 7 is bonded to the bottom of the mesh layer 2 at the bottom of the aerogel insulation cotton body, forming a tight bond.

[0029] This application can be used in the field of thermal insulation cotton technology, or in other fields applicable to this application.
