High-strength color-changing film for automobile

Abstract

The utility model discloses a high-strength color-changing film for an automobile, which comprises a heating layer and a temperature-changing layer, and a black lining layer is arranged between the heating layer and the temperature-changing layer. By arranging the black lining layer, the attached color can be effectively isolated, so that the situation that the normal reflection of the color of the temperature change layer is influenced by the surface color of the attached object is avoided, and as the black lining layer is arranged on the heating layer and the temperature change layer support, the black lining layer can also isolate the influence of the color on the heating layer on the color on the temperature change layer.

Description

Technical Field

[0001] The utility model relates to the technical field of thin films, and more specifically to a high-strength color-changing film for automobiles. Background Art

[0002] Patent number CN212083867U discloses an electrothermochromic film, which includes a stacked heating layer and a temperature-variable layer. The heating layer includes a substrate, which is provided with a plurality of grooves. The grooves are filled with conductive material to form a conductive film with a certain resistance value. The temperature-variable layer contains a thermochromic material. The heat generated by the conductive film after power is applied is conducted to the temperature-variable layer, causing it to change color due to the heat.

[0003] Although the above patent can realize a thermochromic film to present a single color or mixed color effect, a gradient and pattern color change effect or a dynamic color change effect, when the thermochromic film is used, the color of the attached object will change the actual color of the pattern. Therefore, it is necessary to improve the existing thermochromic film. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the actual pattern color of the existing temperature-changing color-changing film will be changed when it is used, so a high-strength color-changing film for automobiles is provided to solve the above problem.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A high-strength color-changing film for automobiles comprises a heating layer and a temperature-changing layer, wherein a black lining layer is arranged between the heating layer and the temperature-changing layer.

[0007] Preferably, the black lining layer is formed by coating one or both sides of a film substrate with black paint.

[0008] Preferably, the black lining layer is made of a black substrate.

[0009] Preferably, a reflective layer is provided on the side of the black lining layer opposite to the temperature-changing layer.

[0010] Preferably: a partition hole is provided on the black lining layer in the area between two adjacent grooves on the corresponding heating layer.

[0011] Preferably: the partition hole is filled with heat insulating glue.

[0012] The beneficial effect of the utility model is that the black lining layer can be effectively isolated from the attached color, thereby preventing the surface color of the attached object from affecting the normal color of the temperature-changing layer. Because the black lining layer is arranged between the heating layer and the temperature-changing layer bracket, the black lining layer can also isolate the influence of the color on the heating layer on the color on the temperature-changing layer.

[0016] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0018] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0019] according to Figure 1-2 As shown, a high-strength color-changing film for automobiles includes a heating layer 1 and a temperature-changing layer 3, and a black lining layer 2 is arranged between the heating layer 1 and the temperature-changing layer 3. The black lining layer 2 can effectively isolate the color of the attached object, thereby preventing the surface color of the attached object from affecting the normal color of the temperature-changing layer 3. Because the black lining layer 2 is arranged on the bracket of the heating layer 1 and the temperature-changing layer 3, the black lining layer 2 can also isolate the influence of the color on the heating layer 1 on the color on the temperature-changing layer 3.

[0020] according to Figure 1-2 As shown, there are two embodiments of the black lining layer 2, one of which is that the black lining layer 2 is formed by coating one or both sides of a film substrate with a black coating; the other is that the black lining layer 2 is formed by a black substrate. It should be noted that the black lining layer 2 in the present application is preferably made of a black film.

[0021] according to Figure 1-2As shown, a partition hole 5 is provided on the black lining layer 2 in the area between two adjacent grooves on the corresponding heating layer 1, and the partition hole 5 is filled with heat-insulating glue 6. The heating layer 1 is provided with a plurality of grooves, and the plurality of grooves are filled with conductive materials. The heat of the conductive materials is transferred to the temperature-changing layer 3 through the black lining layer 2. The setting of the partition hole 5 can effectively prevent the heat in the two adjacent grooves from affecting each other, causing the color change disorder of the color-changing material on the temperature-changing layer 3. The filling of the heat-insulating glue 6 further enhances the heat-insulating effect.

[0022] according to Figure 1-2 As shown, a reflective layer 4 is provided on one side of the black lining layer 2 opposite to the temperature-changing layer 3. The reflective layer 4 is made of a reflective film and is used to increase the color-changing brightness of the temperature-changing layer 3.
