Description

Technical Field

[0001] The utility model relates to the technical field of conductive films, in particular to a conductive film. Background Art

[0002] Conductive films are widely used in liquid crystal displays, OLED displays, touch panels, electromagnetic wave protection, solar cells, heating devices, light-emitting devices and other fields.

[0003] However, in the prior art, it is found that the protective measures for the conductive film are poor and it is easy to wear and water ingress; at the same time, indium is used in most conductive films, but the poor thermal insulation effect of the conductive film may cause the indium to fog when heated. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a conductive film, comprising: a substrate, a surface of which is provided with a plurality of conductive grooves, a conductive layer is fixedly embedded inside the plurality of conductive grooves, and a heat insulation layer 2 is fixedly connected to the surface of the plurality of conductive layers.

[0006] As a preferred implementation, the substrate is an ITO film, a heat insulating layer 1 is fixedly connected to the bottom of the substrate, and the material of the heat insulating layer 1 is zinc oxide.

[0007] As a preferred implementation, the conductive layer is made of indium.

[0008] As a preferred implementation, a waterproof layer is fixedly connected to the top of the second heat-insulating layer, and a protective layer is fixedly connected to the top of the waterproof layer.

[0009] As a preferred embodiment, the material of the second thermal insulation layer is zinc oxide.

[0010] As a preferred implementation, the material of the waterproof layer is isocyanate, and the material of the protective layer is polyethylene terephthalate.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The utility model installs the conductive film at the required positions of liquid crystal displays, OLED displays, touch panels, electromagnetic wave protection, solar cells, heating devices, light-emitting devices, etc. The material of the first and second heat insulation layers is zinc oxide. Zinc oxide can block the penetration of water vapor. This is because the chemical bond force between zinc oxide molecules is strong, forming a dense lattice structure, which makes it difficult for gas molecules to penetrate; the material of the waterproof layer is isocyanate. Isocyanate uses isocyanate polymers as a base material and is combined with a curing agent to form a solid waterproof film during a chemical reaction, showing high waterproof performance; the material of the protective layer is polyethylene terephthalate, which is a highly crystalline polymer with a smooth and shiny surface. It has good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness. The surface of the conductive film is covered by a protective layer, a waterproof layer and a second thermal insulation layer, and the bottom is covered by a first thermal insulation layer to protect the substrate and the conductive layer, thereby increasing the wear resistance and waterproofness of the conductive film. The first thermal insulation layer and the second thermal insulation layer provide thermal insulation protection for the conductive layer at the same time, thereby reducing the heat transfer from the inside and outside of the appliance to the conductive layer, thereby preventing the conductive layer from fogging due to excessively high temperature.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The surface of the conductive film is covered by the protective layer 302, the waterproof layer 301 and the thermal insulation layer 23, and the bottom is covered by the thermal insulation layer 102. The material of 102 and the thermal insulation layer 23 is zinc oxide, which protects the substrate 1 and the conductive layer 2, increases the wear resistance and waterproofness of the conductive film, and the thermal insulation layer 102 and the thermal insulation layer 23 simultaneously provide thermal insulation protection for the conductive layer 2, reduce the heat transfer from the inside and outside of the appliance to the conductive layer 2, and avoid fogging of the conductive layer 2 due to excessive temperature.

[0022] Specifically: the material of the heat insulating layer 102 is zinc oxide, which can block the penetration of water vapor. This is because the chemical bonds between zinc oxide molecules are strong, forming a dense lattice structure, which makes it difficult for gas molecules to penetrate, thus playing a role of heat insulation and preventing the heat inside the appliance from being transferred to the conductive film.

[0023] In one embodiment, the conductive layer 2 is made of indium.

[0024] Specifically: Indium is a metal element with the symbol In and the atomic number 49, located in the fifth period IIIA group of the periodic table. Its single substance is a silvery white metal with a slightly light blue color, very soft in texture, and can be scratched with a fingernail. It has strong plasticity and ductility and can be pressed into sheets.

In this design, the surface of the conductive film is covered by the protective layer 302, the waterproof layer 301 and the heat insulation layer 23, and the bottom is covered by the heat insulation layer 102, which protects the substrate 1 and the conductive layer 2, and increases the wear resistance and waterproofness of the conductive film.

[0027] In one embodiment, the material of the second heat insulation layer 3 is zinc oxide.

[0028] Specifically: the material of the thermal insulation layer 2 3 is zinc oxide, which can block the penetration of water vapor. This is because the chemical bonds between zinc oxide molecules are strong, forming a dense lattice structure, which makes it difficult for gas molecules to penetrate, thus playing a role in thermal insulation and preventing external heat from being transferred to the conductive film.

[0029] In one embodiment, the waterproof layer 301 is made of isocyanate, and the protective layer 302 is made of polyethylene terephthalate.

[0030] Specifically: the waterproof layer 301 is made of isocyanate, which is based on isocyanate polymers and is combined with a curing agent to form a solid waterproof film in the chemical reaction process, showing high waterproof performance; the protective layer 302 is made of polyethylene terephthalate, which is a highly crystalline polymer with a smooth and shiny surface. It has good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness. In this design, the surface of the conductive film is covered by the protective layer 302, the waterproof layer 301 and the heat insulation layer 23, and the bottom is covered by the heat insulation layer 102, which protects the substrate 1 and the conductive layer 2, and increases the wear resistance and waterproofness of the conductive film.

It has good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness. The surface of the conductive film is covered by a protective layer 302, a waterproof layer 301 and a thermal insulation layer 3, and the bottom is covered by a thermal insulation layer 102, which protects the substrate 1 and the conductive layer 2, thereby increasing the wear resistance and waterproofness of the conductive film. The thermal insulation layer 102 and the thermal insulation layer 2 3 simultaneously provide thermal insulation protection for the conductive layer 2, reducing the heat transfer from the inside and outside of the appliance to the conductive layer 2, thereby preventing the conductive layer 2 from fogging due to excessive temperature.
