Description

Technical Field

[0001] The utility model relates to the technical field of release films, in particular to a high-residue release film for ultra-thin adhesive tapes. Background Art

[0002] High-residue release film is a high-performance, multifunctional film material with a wide range of applications. It is not only used to fix and protect small components in the manufacture of electronic products, but also used for body bonding and interior assembly in automobile manufacturing, and even used for sealing and connecting aircraft and spacecraft in the aerospace field.

[0003] The patent document with application number 201520122820.8 discloses a release film, which includes a transparent substrate and a pattern printed on the transparent substrate, and the pattern defines a plurality of transparent windows on the transparent substrate. The release film provided by the utility model can inspect and observe the glue spreading condition of the tape when applied to the tape, and when the tape is applied to the product.

[0004] However, traditional high-residue release films used for ultra-thin tapes are more likely to deform or get damp on both sides when pulled by external forces or in a humid environment, affecting the tape's fitting accuracy and stability, making it impossible for the tape to be accurately fitted to the target object, thereby affecting the quality and performance of the entire product. Utility Model Content

[0005] The utility model discloses a high-residue release film for ultra-thin tapes, aiming to solve the technical problem that when pulled by external force or in a humid environment, both sides of the release film are more likely to deform or get damp, affecting the lamination accuracy and stability of the tape, making it impossible for the tape to be accurately laminar on the target object, thereby affecting the quality and performance of the entire product.

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

[0007] A high-residue release film for ultra-thin tapes, comprising a substrate layer, a release agent layer and a surface treatment layer, further comprising: a first protective layer is arranged on the top outer wall of the substrate layer, a first waterproof layer and a second waterproof layer are connected at both ends of the release agent layer and the surface treatment layer, a card slot is opened on the outer wall on the opposite side of the first waterproof layer and the second waterproof layer, a connecting slot is opened at both ends of the release agent layer and the surface treatment layer, and a second protective layer and a third protective layer are card-connected to the inner wall of the card slot and the connecting slot.

[0008] In this case, a wrapping structure is formed on the outside of the substrate layer through layer-by-layer structure clamping, which reduces the possibility of interlayer separation due to external force or environmental changes, effectively improves the stability of the outer structure of the release film, and provides all-round protection for the release film. The addition of the first waterproof layer and the second waterproof layer in the vertical direction can effectively prevent moisture penetration, and the performance durability is improved, thereby extending its service life.

[0009] In a preferred embodiment, dovetail grooves are provided on the outer walls on opposite sides of the second protective layer and the third protective layer, both ends of the first protective layer are clamped on the inner walls of the dovetail grooves, the first protective layer, the second protective layer and the third protective layer are in an H-shaped structure and are all made of carbon fiber material.

[0010] The first protective layer, the second protective layer and the third protective layer are connected through the dovetail groove structure to form an H-shaped structure, which disperses stress and pressure in the longitudinal and transverse directions, effectively resisting deformation and distortion caused by external forces, thereby ensuring that the ultra-thin tape can maintain its complete shape and performance during use. Carbon fiber material has the characteristics of high strength and light weight, which can enhance the overall structural strength of the release film, making it more resistant to external physical impact and stress, thereby extending its service life. In addition, the thermal expansion coefficient of carbon fiber material is low. In a high temperature environment, the deformation of the protective layer is small, which can maintain the overall dimensional stability of the release film.

[0011] In a preferred solution, microporous structures are provided on one outer wall of the first waterproof layer and the second waterproof layer.

[0012] The design of the microporous structure ensures that the waterproof layer still has a certain degree of air permeability, which helps prevent internal moisture accumulation, keeps the release film dry, and ensures a balance between waterproofness and breathability.

[0013] As can be seen from the above, a high residual release film for ultra-thin tape includes a substrate layer, a release agent layer and a surface treatment layer, and also includes: a first protective layer is arranged on the top outer wall of the substrate layer, the first waterproof layer and the second waterproof layer are connected at both ends of the release agent layer and the surface treatment layer, a card slot is opened on the outer wall on the opposite side of the first waterproof layer and the second waterproof layer, the release agent layer and the surface treatment layer are opened at both ends of the connection groove, and the second protective layer and the third protective layer are clamped on the inner wall of the card slot and the connection groove. The high residual release film for ultra-thin tape provided by the utility model has the technical effect of improving the stability of the release film and the waterproof performance.

[0019] 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.

[0020] The utility model discloses a high-residue release film for ultra-thin tape, which is mainly used in scenarios where, when pulled by external force or in a humid environment, both sides of the release film are more likely to deform or get damp, affecting the fitting accuracy and stability of the tape, making it impossible for the tape to be accurately fitted on the target object, thereby affecting the quality and performance of the entire product.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A high-residue release film for ultra-thin tape comprises a substrate layer 1, a release agent layer 2 and a surface treatment layer 3, and further comprises: a first protective layer 4 is arranged on the top outer wall of the substrate layer 1, a first waterproof layer 7 and a second waterproof layer 8 are connected to both ends of the release agent layer 2 and the surface treatment layer 3, a card groove is opened on the outer wall on the opposite side of the first waterproof layer 7 and the second waterproof layer 8, a connecting groove is opened at both ends of the release agent layer 2 and the surface treatment layer 3, and a second protective layer 5 and a third protective layer 6 are carded on the inner walls of the card groove and the connecting groove.

[0022] In the specific implementation process, a wrapping structure is formed on the outside of the substrate layer 1 through the layer-by-layer structure being connected together, which reduces the possibility of interlayer separation caused by external force or environmental changes, effectively improves the stability of the outer structure of the release film, and provides all-round protection for the release film. The addition of the first waterproof layer 7 and the second waterproof layer 8 in the vertical direction can effectively prevent moisture penetration, and the performance durability is improved, thereby extending its service life.

[0023] Reference Figure 2 and Figure 3 In a preferred embodiment, dovetail grooves are opened on the outer walls of the opposite sides of the second protective layer 5 and the third protective layer 6, and both ends of the first protective layer 4 are clamped on the inner walls of the dovetail grooves. The first protective layer 4, the second protective layer 5 and the third protective layer 6 are in an H-shaped structure and are all made of carbon fiber material.

[0024] The first protective layer 4, the second protective layer 5 and the third protective layer 6 are connected by a dovetail groove structure to form an H-shaped structure, which disperses stress and pressure in the longitudinal and transverse directions, effectively resists deformation and distortion caused by external forces, thereby ensuring that the ultra-thin tape can maintain its complete shape and performance during use. The carbon fiber material has the characteristics of high strength and light weight, which can enhance the overall structural strength of the release film, making it more resistant to external physical impact and stress, thereby extending its service life. The carbon fiber material has a low thermal expansion coefficient. In a high temperature environment, the deformation of the protective layer is small, and the overall dimensional stability of the release film can be maintained.

[0025] Reference Figure 1 and Figure 2 In a preferred embodiment, the top outer wall of the first protective layer 4 is connected to the bottom outer wall of the release agent layer 2, and the release agent layer 2 is made of an organosilicon modified material.

[0026] The release agent layer 2 made of the organosilicon modified material has an excellent property of reducing the adhesion of the surface of the object, so that the ultra-thin tape can be easily peeled off from the release film without leaving any residual adhesive or traces.

[0027] Reference Figure 1 and Figure 4 In a preferred embodiment, microporous structures are provided on the outer walls of one side of the first waterproof layer 7 and the second waterproof layer 8.

[0028] The design of the microporous structure ensures that the waterproof layer still has a certain degree of air permeability, which helps prevent internal moisture accumulation, keeps the release film dry, and ensures a balance between waterproofness and breathability.

[0029] Reference Figure 2In a preferred embodiment, the bottom outer wall of the substrate layer 1 is connected to the top outer wall of the surface treatment layer 3, and the surface treatment layer 3 is coated with a siloxane coating. The siloxane coating has excellent adhesion and durability, effectively improves the water resistance and corrosion resistance of the substrate layer 1, and can resist erosion by various environmental factors, such as ultraviolet rays, moisture, chemicals, etc.

[0030] Reference Figure 1 In a preferred embodiment, the substrate layer 1 is made of PET. PET, as the substrate layer 1 of the high-residue release film of the ultra-thin tape, can meet the needs of various application scenarios due to its excellent physical properties, heat resistance, chemical compatibility, electrical insulation and easy processing.

[0031] Working principle: When in use, the H-shaped carbon fiber protective structure disperses stress and pressure in both the longitudinal and transverse directions, so that the release film can maintain better stability when subjected to external forces, reducing the possibility of deformation and damage. The microporous structure on the side of the release film has a certain air permeability, which helps to prevent internal moisture accumulation, keep the release film dry, and extend its service life.

[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. 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.
