Description

Technical Field

[0001] This utility model belongs to the field of multicolor adhesive film technology, and in particular relates to a high-temperature resistant multicolor adhesive film. Background Technology

[0002] Fabric-covered films are widely used in numerous industrial and everyday applications. However, existing ordinary fabric-covered films have many shortcomings. When exposed to high-temperature environments, such as in high-temperature industrial production workshops, kitchen appliance surface decoration, and protective decoration of automotive engine peripheral parts, ordinary fabric-covered films are prone to serious problems. On the one hand, their color stability is poor at high temperatures, and they are prone to fading, which greatly affects the decorative aesthetics. Therefore, some high-temperature resistant, multi-colored fabric-covered films have emerged on the market.

[0003] However, some high-temperature resistant multicolor adhesive films on the market may experience relative displacement between the colored layer and the protective layer when the film is subjected to external forces such as stretching or bending during use. Traditional coatings may delaminate or peel off due to insufficient interfacial adhesion. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a high-temperature resistant multicolor adhesive film. By setting grooves and raised textures, when the film material is subjected to external forces such as stretching or bending, the structure of the raised textures embedded in the grooves can prevent relative displacement between the color layer and the protective layer, avoiding the delamination and peeling problems caused by insufficient interfacial adhesion of traditional coatings. After the raised textures are embedded in the grooves, the contact area between the color layer and the protective layer is maximized. Compared with a smooth interface, this structure has a higher bonding strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant multicolor adhesive film, comprising a base layer, a coloring layer, and a protective layer. The base layer is made of a high-temperature resistant polymer material. A coloring layer is disposed on the upper surface of the base layer. The coloring layer contains a high-temperature resistant pigment and a heat stabilizer. A protective layer is disposed on the upper surface of the coloring layer. The protective layer is made of a transparent high-temperature resistant material. A groove is formed at the top of the coloring layer, and a textured protrusion is formed at the bottom of the protective layer. The textured protrusion is disposed inside the groove.

[0006] Furthermore, the high-temperature resistant polymer material of the base layer is polyimide, the high-temperature resistant pigment in the coloring layer is ceramic pigment, and the base layer also contains nano-silica and coupling agent.

[0007] Furthermore, the heat stabilizer in the coloring layer is a phosphite heat stabilizer, and the transparent high-temperature resistant material of the protective layer is a fluorinated resin.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By incorporating grooves and raised textures, when the film material is subjected to external forces such as stretching or bending, the structure of the raised textures embedded in the grooves can prevent relative displacement between the coloring layer and the protective layer, thus avoiding the delamination and peeling problems caused by insufficient interfacial adhesion in traditional coatings. After the raised textures are embedded in the grooves, the contact area between the coloring layer and the protective layer is maximized. Compared with a smooth interface, this structure has a higher bonding strength. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Example

[0016] See appendix Figure 1-3 As shown, a high-temperature resistant multicolor adhesive film includes a base layer 1, a coloring layer 2, and a protective layer 3. The base layer 1 is made of a high-temperature resistant polymer material. The upper surface of the base layer 1 is provided with the coloring layer 2, which contains high-temperature resistant pigments and heat stabilizers. The upper surface of the coloring layer 2 is provided with the protective layer 3, which is made of a transparent high-temperature resistant material. The top of the coloring layer 2 is provided with a groove 5, and the bottom of the protective layer 3 is provided with a textured protrusion 4, which is located inside the groove 5.

[0017] The high-temperature resistant polymer material of the base layer 1 is polyimide, and the high-temperature resistant pigment in the coloring layer 2 is ceramic pigment. The base layer 1 also contains nano-silica and a coupling agent. The nano-silica is used to enhance the mechanical properties and thermal stability of the base layer 1, and the coupling agent is used to improve the compatibility between the nano-silica and the polyimide.

[0018] The heat stabilizer in the coloring layer 2 is a phosphite heat stabilizer, and the transparent high-temperature resistant material in the protective layer 3 is a fluorinated resin.

[0019] Working principle: Because the base layer 1 is made of high-temperature resistant polymer and the coloring layer 2 is made of heat stabilizer and high-temperature resistant pigment, this adhesive film has strong stability at high temperatures. Due to the selection of high weather resistance and high-temperature resistant pigments, coupled with the synergistic effect of heat stabilizer, the color change is almost imperceptible to the naked eye, meeting the decorative and aesthetic needs of high-temperature scenarios. The outermost protective layer 3 is made of fluorinated resin material, which can effectively block ultraviolet rays and resist chemical corrosion and wear. The coloring layer 2 can be mixed with different high-temperature resistant pigments to create a rich variety of colors to meet the personalized decorative needs of users. Through the setting of grooves 5 and textured protrusions 4, when the film material is subjected to external forces such as stretching or bending, the structure of the protrusions embedded in the grooves 5 can prevent relative displacement between the coloring layer 2 and the protective layer 3, avoiding the delamination and peeling problems caused by insufficient interface adhesion of traditional coatings. After the protrusions are embedded in the grooves 5, the contact area between the coloring layer 2 and the protective layer 3 is maximized. Compared with a smooth interface, the bonding strength of this structure is higher.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0021] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
