Description

Technical Field

[0001] The utility model relates to the technical field of new energy base films, in particular to a non-silicon release film for new energy tapes. Background Art

[0002] Non-silicon release film is a kind of film material with special functions. It is different from traditional silicon-based release film. It does not contain silicon and is mainly composed of elements such as oxides and nitrides. This film material has many significant advantages, such as excellent chemical stability, high temperature stability and corrosion resistance. Therefore, it can play an excellent release effect in high temperature and strong acid and alkali environment.

[0003] Existing non-silicone-based release films are widely used in new energy tapes. They have stable performance and strong temperature and weather resistance. However, during use, when the non-silicone-based release film is pulled, it is unevenly stressed and damaged. Utility Model Content

[0004] The utility model discloses a non-silicon release film for a new energy adhesive tape, aiming to solve the technical problem that the existing non-silicon-based release film is damaged due to uneven force when being pulled during use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A non-silicone release film for new energy tape comprises a base film, wherein a first elastic layer is arranged on the top of the base film, a second elastic layer is arranged on the bottom of the base film, a wear-resistant layer is arranged on the top of the first elastic layer, and a protective layer is arranged on the bottom of the second elastic layer.

[0007] By respectively arranging the first elastic layer and the second elastic layer on the upper and lower surfaces of the base film, when the base film is pulled, the pulling force can be dispersed to the first elastic layer and the second elastic layer as a whole, thereby reducing the stress at the pulling position, thereby preventing the base film from being damaged, improving the durability of the base film, and extending the service life of the base film.

[0008] In a preferred embodiment, the protective layer includes an outer corona layer, an antistatic layer is arranged on the top of the outer corona layer, an inner corona layer is arranged on the top of the antistatic layer, the inner corona layer is arranged at the bottom of the second elastic layer, and the outer corona layer is arranged on the top of the outer protective layer.

[0009] By setting up the antistatic layer, the antistatic performance can be improved during the die-cutting process, which is very important for improving die-cutting accuracy and ensuring product quality. The main function of the antistatic layer is to prevent the generation and accumulation of static electricity, thereby avoiding various problems caused by static electricity during the die-cutting process, such as material adhesion, reduced accuracy, etc. The outer corona layer and the inner corona layer effectively change the morphology of the base film surface, changing it from a smooth plane to a rough surface, thereby enhancing the adhesion between the antistatic layer and the antistatic layer, effectively preventing the antistatic layer from falling off. At the same time, the outer corona layer and the inner corona layer also improve the wettability and wettability of the base film, so that the antistatic coating can be more evenly covered on the surface of the film layer, further enhancing the composite stability.

[0010] As can be seen from the above, the non-silicone release film for new energy tape comprises a base film, a first elastic layer is arranged on the top of the base film, a second elastic layer is arranged on the bottom of the base film, a wear-resistant layer is arranged on the top of the first elastic layer, and a protective layer is arranged on the bottom of the second elastic layer. The non-silicone release film for new energy tape provided by the utility model has the technical effect of reducing the stress of the pulling part, thereby preventing the base film from being damaged, improving the durability of the base film, and extending the service life of the base film.

[0019] The non-silicone release film for new energy tape disclosed in the utility model is mainly applied to the scenario where the existing non-silicone-based release film is damaged due to uneven force when being pulled during use.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A non-silicone release film for new energy tape includes a base film 5, a first elastic layer 4 is arranged on the top of the base film 5, a second elastic layer 6 is arranged on the bottom of the base film 5, a wear-resistant layer 3 is arranged on the top of the first elastic layer 4, and a protective layer 7 is arranged on the bottom of the second elastic layer 6.

[0021] By respectively arranging the first elastic layer 4 and the second elastic layer 6 on the upper and lower surfaces of the base film 5, when the base film 5 is pulled, the pulling force can be dispersed to the first elastic layer 4 and the second elastic layer 6 as a whole, thereby reducing the stress at the pulling position, thereby preventing the base film 5 from being damaged, improving the durability of the base film 5, and extending the service life of the base film 5.

[0022] Reference Figure 1 and Figure 5 In a preferred embodiment, an OCA adhesive layer 2 is provided on the top of the wear-resistant layer 3, a release paper 1 is provided on the top of the OCA adhesive layer 2, an outer protective layer 8 is provided on the bottom of the protective layer 7, the wear-resistant layer 3 is made of PET material, the outer protective layer 8 is made of PET material, and the first elastic layer 4 and the second elastic layer 6 are both provided with mutually crossed elastic connecting keys 12, and a connecting column 13 is provided in the middle part of the elastic connecting key 12.

[0024] By setting the antistatic layer 10, the antistatic performance can be improved during the die-cutting process, which is very important for improving the die-cutting accuracy and ensuring product quality. The main function of the antistatic layer 10 is to prevent the generation and accumulation of static electricity, thereby avoiding various problems caused by static electricity during the die-cutting process, such as material adhesion, reduced accuracy, etc. The outer corona layer 9 and the inner corona layer 11 effectively change the morphology of the surface of the base film 5, changing it from a smooth plane to a rough surface, thereby enhancing the adhesion between the antistatic layer 10 and the antistatic layer 10, effectively preventing the antistatic layer 10 from falling off. At the same time, the outer corona layer 9 and the inner corona layer 11 also improve the wettability and wettability of the base film 5, so that the antistatic coating can be more evenly covered on the surface of the film layer, further enhancing the composite stability.

[0025] Working principle: By arranging the first elastic layer 4 and the second elastic layer 6 on the upper and lower surfaces of the base film 5 respectively, when the base film 5 is pulled, the pulling force can be dispersed to the first elastic layer 4 and the second elastic layer 6 as a whole, thereby reducing the stress at the pulling position. The combination of the outer corona layer 9, the inner corona layer 11 and the antistatic layer 10 enhances the overall performance of the base film 5 and improves stability and reliability.
