Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive films, in particular to an adhesive film with high adhesion and good heat insulation effect. Background Art

[0002] As a material widely used on the surface of electronic products, adhesive film plays a vital role in components such as notebooks, cameras, and circuit boards. However, many adhesive film products on the market currently have obvious performance deficiencies. These problems gradually become prominent during the use of electronic products, affecting the user experience and the overall performance of the product.

[0003] Poor thermal insulation: In electronic products, especially highly integrated devices such as laptops and cameras, efficient thermal insulation is a key factor in ensuring product stability and durability. However, many existing film products do not have ideal thermal insulation effects and cannot effectively block heat transfer, causing electronic components to be easily damaged in high temperature environments, affecting product performance and lifespan.

[0004] Delamination and peeling: The original intention of the multi-layer structure design of the film is to improve the overall performance of the product. However, in actual applications, due to insufficient adhesion between the layers or poor material compatibility, delamination and peeling often occur, which not only destroys the overall structure of the film and reduces its heat insulation and protection effects, but also may cause electronic components to be exposed to the external environment, increasing the risk of damage;

[0005] Easy to damage: The mechanical strength and durability of the film are crucial to protecting electronic components from external mechanical damage. However, existing film materials often have problems such as insufficient toughness and poor impact resistance, making the film easily damaged during use. This not only affects the aesthetics of the product, but is also likely to cause damage to electronic components, causing inconvenience and economic losses to users. Utility Model Content

[0006] The utility model provides an adhesive film with high adhesion and good heat insulation effect, aiming to solve the problems that existing adhesive film products are insufficient in heat insulation effect, structural stability and mechanical strength.

[0007] The utility model is achieved in that an adhesive film with high adhesion and good heat insulation effect comprises a film body; a diaphragm structure arranged on both sides of the film body; the diaphragm structure comprises: an inner lining layer arranged on the outer walls of both sides of the film body; a metallized polyester layer arranged on the outer side of the inner lining layer; a magnetron sputtering layer arranged on the outer side of the metallized polyester layer; a barrier layer arranged on the outer side of the magnetron sputtering layer; a wear-resistant layer arranged on the outer side of the barrier layer; the film body, the inner lining layer, the metallized polyester layer, the magnetron sputtering layer, the barrier layer and the wear-resistant layer are connected by a thin adhesive layer.

[0008] Preferably, the metallized polyester layer includes a first metal layer and a multi-layer silicon dioxide layer, and the metal layer and the multi-layer silicon dioxide layer are an integrated structure.

[0009] Preferably, the magnetron sputtering layer includes a second metal layer and aluminum oxide, and the metal layer and the aluminum oxide form an integrated structure.

[0010] Preferably, the thickness of the diaphragm structure is 60-80 um.

[0011] Preferably, a heat conduction channel is provided in the diaphragm structure, and the heat conduction channel is filled with a heat conductive material.

[0012] Preferably, a release paper is arranged on the outer side of the wear-resistant layer and the release paper completely covers the outer surface of the wear-resistant layer.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] First, the device has excellent thermal insulation and stability. It adopts a multi-layer structure, especially the metallized polyester layer, the multi-layer silica layer and the magnetron sputtering layer. These carefully selected material layers jointly enhance the thermal insulation performance of the film. The metal layer effectively blocks the transfer of heat due to its high reflectivity, while the silica layer helps the film resist chemical corrosion and oxidation in the external environment due to its excellent chemical stability. It is worth mentioning that the magnetron sputtering layer not only has excellent thermal insulation performance, but also exhibits excellent resistance to thermal oxidation, which further consolidates the thermal insulation effect and stability of the film. On the whole, the synergistic effect of these material layers enables the device to reach a higher level in terms of thermal insulation and stability.

[0015] Second: The multi-layer structure of the film of this device and the thin adhesive layer between each layer provide good connection and buffering effect, preventing the film from delamination or peeling during use, and can resist external mechanical damage and protect the film from wear and damage. These characteristics jointly enhance the mechanical strength and durability of the film, so that it exhibits good performance in practical applications.

[0016] Third: By opening a heat-conducting channel in the diaphragm structure and filling it with thermally conductive materials, the thermal conductivity of the film can be effectively improved and its thermal insulation effect can be enhanced. This design enables the film to perform better in application scenarios with high temperatures or requiring efficient thermal insulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should be noted that, since existing adhesive film products have insufficient thermal insulation effects, structural stability and mechanical strength, this solution achieves excellent thermal insulation and stability through a multi-layer structural design. The carefully selected material layers such as the metallized polyester layer 3 and the magnetron sputtering layer 4 work synergistically to enhance the thermal insulation performance of the adhesive film and effectively resist the invasion of the external environment.

[0028] The barrier layer 5 is located outside the magnetron sputtering layer 4, and its main function is to prevent external factors such as moisture and oxygen from penetrating into the film body 1 through the magnetron sputtering layer 4; by forming a barrier, it prevents the contact between external factors and internal materials, thereby maintaining the stability and performance of the film body 1; the wear-resistant layer 6 is located outside the barrier layer 5, and is made of high-hardness material, with excellent wear resistance and scratch resistance; it can resist external mechanical damage and protect the film body 1 from wear and damage;

[0031] In this embodiment, the high reflective performance of the first metal layer 8 effectively improves the thermal insulation effect of the film body 1. Silicon dioxide is a material with high chemical stability and can resist chemical corrosion and oxidation in the external environment. By alternately stacking silicon dioxide films and the first metal layer 8, a structure similar to optical interference is formed. This structure can further improve the reflective effect of the metal layer and enhance its ability to block heat.

[0034] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the thickness of the diaphragm structure 14 is 60-80 um.

[0035] In this embodiment, the thickness of the diaphragm structure 14 will affect the overall performance of the membrane body 1, including thermal insulation effect, mechanical strength, durability and other aspects. Selecting a diaphragm structure 14 thickness of 60-80 microns can balance factors such as mechanical strength, thermal insulation effect and manufacturing cost to a certain extent, so that the membrane body 1 exhibits good performance in practical applications.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, a heat-conducting channel 12 is provided in the diaphragm structure 14 , and the heat-conducting channel 12 is filled with a heat-conducting material.

[0037] In this embodiment, when heat acts on the membrane body 1, the thermally conductive material can quickly absorb and transfer the heat, and quickly transfer the heat to other parts of the membrane body 1 through the thermal conductive channel 12, which can effectively reduce the accumulation of heat in the diaphragm structure 14 and reduce the transfer of heat to the inside of the membrane body 1, thereby improving the thermal insulation effect of the membrane body 1.

[0040] Working principle: The membrane body 1 is the basic structure of the film and carries the functions and characteristics of the entire film; the inner lining layer 2 is located on the outer walls of both sides of the membrane body 1, and its main function is to provide support and protection to ensure that the film is not easily deformed or damaged during use; in addition, the inner lining layer 2 also enhances the fit and sealing between the membrane body 1 and the diaphragm structure 14, effectively preventing external factors such as moisture and oxygen from penetrating into the membrane body 1;

[0041] The metallized polyester layer 3 is located on the outside of the inner lining layer 2. This layer has the ability to reflect heat, which can reduce the possibility of heat transfer to the inside of the film body 1, thereby improving the thermal insulation effect of the film body 1; the multi-layer silicon dioxide layer 9 further enhances the stability and durability of the first metal layer 8, and maintains the performance of the film stable by resisting chemical corrosion and oxidation in the external environment;

[0045] The diaphragm structure 14 is located inside the film, and its thickness has an important influence on the overall performance of the film; selecting a diaphragm structure 14 thickness of 60-80 microns can balance factors such as mechanical strength, thermal insulation effect and manufacturing cost to a certain extent, so that the film can show good performance in practical applications; when heat acts on the film, the thermal conductive material in the heat conduction channel 12 can quickly absorb and transfer heat, reduce the accumulation of heat in the diaphragm structure 14, and thus improve the thermal insulation effect of the film;

[0046] The release paper 13 is a protective material and is arranged on the outside of the wear-resistant layer 6 to completely cover its outer surface. The presence of the release paper 13 can prevent the wear-resistant layer 6 from being scratched, contaminated or otherwise damaged during the manufacturing, transportation and storage processes, thereby protecting the integrity and aesthetics of the film.
