Description

Technical Field

[0001] The utility model relates to the technical field of release films, in particular to a release film with vertical stripes capable of exhausting air. Background Art

[0002] Release film is a special film material that is commonly used to protect the screens and surfaces of electronic products, automotive glass and other surface materials, as well as architectural glass, stone and metal surfaces from wear and damage.

[0003] The patent document with application number 202223205535.1 discloses an ultra-dense grid exhaust release film, which relates to the field of release film technology, including an exhaust layer, which is arranged on one side of a PET substrate, a tensile layer, which is used to prevent the exhaust layer from deforming and affecting the exhaust effect; an air cavity layer, which is used to temporarily store the air in the exhaust layer and discharge it; wherein the exhaust layer is provided with a uniformly distributed diffuse breathable texture, and the diffuse breathable texture is provided with multiple breathable grids.

[0004] However, traditional release films are prone to generate static electricity during use, which weakens the adhesion between film layers and causes demolding of film layers between release films, resulting in poor use effect of the release films. Utility Model Content

[0005] The utility model discloses a vertical-grained release film with exhaust air, aiming to solve the technical problem that a traditional release film is prone to generate static electricity during use, which weakens the adhesion between film layers and causes demoulding of film layers between the release films, resulting in poor use effect of the release film.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The exhaustable vertical-grained release film comprises a release film body, wherein the release film body is provided with a coating layer, an antistatic layer, a vertical-grained film layer and a substrate layer in sequence from top to bottom, both sides of the antistatic layer are provided with a wrapping structure, and a first connecting layer and a second connecting layer are provided on the upper and lower sides of the antistatic layer respectively, and the antistatic layer is used to wrap the coating layer, the vertical-grained film layer and the substrate layer.

[0008] In this scheme, the release film body is composed of a coating layer, an antistatic layer, a vertical-grained film layer and a substrate layer. The antistatic layer is used to prevent the generation of static electricity, thereby improving the stability and safety of the release film body during use. The wrapping structure of the antistatic layer tightly wraps the coating layer, the vertical-grained film layer and the substrate layer on the upper and lower sides of the antistatic layer. The antistatic layer is used to limit the film layer, which prevents static electricity and enhances the adhesion between the film layers. The film layers are tightly connected and will not desiliconize, so the use effect of the release film body is better.

[0009] In a preferred embodiment, the surface of the coating layer is provided with a criss-cross grid, and the grid is used in conjunction with the coating layer.

[0010] By adopting the above technical solution, the grids set on the coating layer make it easier to apply the silicone oil release agent on the coating layer. The crisscrossing grids lock the silicone oil release agent inside each grid and lay it evenly, so that the release film body has ultra-low surface energy, which can effectively prevent glue or adhesive from adhering to the film and achieve the effect of easy peeling.

[0011] In a preferred embodiment, the surface of the vertical-striped film layer is provided with vertical-striped bodies distributed at equal distances, and the vertical-striped bodies are used in conjunction with the vertical-striped film layer, and the vertical-striped bodies respectively form exhaust channels with the antistatic layer and the substrate layer.

[0012] By adopting the above technical solution, a vertical-grain body is set on the vertical-grain film layer, and an exhaust channel is formed between the vertical-grain body and the upper and lower film layers bonded together, which not only increases the surface texture but also provides an escape channel for air, so that air can be effectively removed during the bonding process to prevent the generation of bubbles.

[0013] As can be seen from the above, the exhaust vertical stripe release film comprises a release film body, wherein the release film body is sequentially provided with a coating layer, an antistatic layer, a vertical stripe film layer and a substrate layer from top to bottom, both sides of the antistatic layer are provided with a wrapping structure, and the upper and lower sides of the antistatic layer are respectively provided with a first connecting layer and a second connecting layer, and the antistatic layer is used to wrap the coating layer, the vertical stripe film layer and the substrate layer. The exhaust vertical stripe release film provided by the utility model has the technical effects of antistatic, preventing glue or adhesive from adhering to the film, preventing the generation of bubbles, effectively removing air, not desiliconizing and achieving easy peeling.

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0019] The ventable vertical-grained release film disclosed in the utility model is mainly used in scenarios where conventional release films are prone to generate static electricity during use, which weakens the adhesion between film layers and causes demolding of film layers between the release films, resulting in poor use effects of the release film.

[0020] Reference Figure 1 and Figure 2 The exhaust vertical-grain release film comprises a release film body 1, on which a coating layer 2, an antistatic layer 3, a vertical-grain film layer 4 and a substrate layer 5 are sequentially arranged from top to bottom. Both sides of the antistatic layer 3 are arranged as a wrapping structure. The upper and lower sides of the antistatic layer 3 are respectively provided with a first connecting layer 6 and a second connecting layer 7. The antistatic layer 3 is used to wrap the coating layer 2, the vertical-grain film layer 4 and the substrate layer 5.

[0021] In the specific working process, the release film body 1 is composed of a coating layer 2, an antistatic layer 3, a vertical-grained film layer 4 and a substrate layer 5. The antistatic layer 3 is utilized to prevent the release film body 1 from generating static electricity during use. The wrapping structure of the antistatic layer 3 wraps the limiting coating layer 2, the vertical-grained film layer 4 and the substrate layer 5. The coating layer 2 is tightly wrapped on the upper side of the antistatic layer 3, and the vertical-grained film layer 4 and the substrate layer 5 are tightly wrapped on the lower side of the antistatic layer 3. While preventing static electricity, the adhesion between the film layers is enhanced, and the film layers are tightly connected and will not desiliconize.

[0022] Among them, notches are provided on the outer walls on both sides of the coating layer 2 and the substrate layer 5, and the notches are adapted to the antistatic layer 3. In this way, the structure of the antistatic layer 3 is utilized to limit and clamp the coating layer 2 and the substrate layer 5, so that the film layers are tightly connected.

[0023] Among them, the first connecting layer 6 is used to connect the coating layer 2 and the antistatic layer 3, and the second connecting layer 7 is used to connect the vertical-striped film layer 4 and the substrate layer 5. In this way, the first connecting layer 6 and the second connecting layer 7 play a connecting role. The first connecting layer 6 is used to connect the coating layer 2 on the upper side of the antistatic layer 3, and the second connecting layer 7 is used to connect the vertical-striped film layer 4 and the substrate layer 5 on the lower side of the antistatic layer 3, so that the film layers are fixed and stable.

[0024] Reference Figure 1 and Figure 3 In a preferred embodiment, the surface of the coating layer 2 is provided with a criss-cross grid 8 , and the grid 8 is used in conjunction with the coating layer 2 .

[0025] Specifically, the coating layer 2 needs to be coated with a silicone oil release agent. A grid 8 is provided on the coating layer 2 to make it easier to apply the silicone oil release agent. The grids 8 crisscrossed horizontally and vertically lock the silicone oil release agent inside each grid 8, making the laying more uniform.

[0026] Reference Figure 1 In a preferred embodiment, the surface of the vertical-grained film layer 4 is provided with vertical-grained bodies distributed at equal distances, and the vertical-grained bodies are used in conjunction with the vertical-grained film layer 4, and the vertical-grained bodies form exhaust channels between the antistatic layer 3 and the substrate layer 5 respectively.

[0027] Specifically, a vertical-grain body is provided on the vertical-grain film layer 4. The vertical-grain shape is usually in the form of an elongated strip or a linear structure, which is distributed at a certain interval and arrangement, and forms an exhaust channel with the upper and lower film layers bonded together, which not only increases the surface texture but also provides an escape channel for the air, so that the air can be effectively removed during the bonding process to prevent the generation of bubbles.

[0028] Reference Figure 1 In a preferred embodiment, the substrate layer 5 is made of PET material.

[0029] Specifically, the substrate layer 5 uses PET polyester film as the substrate. The PET material has good mechanical properties, chemical stability and transparency, so that the release film body 1 can maintain stable performance and a long service life during use.

[0030] Working principle: When in use, the release film body 1 is composed of a coating layer 2, an antistatic layer 3, a vertical-grained film layer 4 and a substrate layer 5. The wrapping structure of the antistatic layer 3 allows the upper and lower sides of the antistatic layer 3 to limit and fix the coating layer 2, the vertical-grained film layer 4 and the substrate layer 5, thereby preventing static electricity and enhancing the adhesion between the film layers. The film layers are tightly connected and will not desiliconize. A grid 8 is arranged on the coating layer 2 to evenly spread the coated silicone oil release agent. A vertical-grained body is arranged on the vertical-grained film layer 4 to provide an escape channel for air, effectively remove air and prevent the generation of bubbles. The substrate layer 5 is made of PET material so that the release film body 1 can maintain stable performance and a long service life during use.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
