The utility model discloses an automobile highlight black film with laser modeling patterns, and relates to the technical field of automobile films. The black film layer is connected to the bottom of the highlight coating; and an icon is formed on the surface of the black film layer through laser etching. According to the automobile highlight black film with the laser modeling patterns, due to the fact that the black film is made of the PVC material, and the low-frequency cold light laser acts on the black film, the color on the surface of the black film is decomposed, the black film is faded, and therefore the patterns in different shapes are formed, and the problem that when an existing automobile black film is used, the color of the black film cannot be changed easily is effectively solved. The technical problem that the decorative effect cannot be achieved due to the fact that the black film is not provided with patterns is solved, the decorative effect of the black film is achieved, and the application range of the black film is widened.

Description

Technical Field

[0001] The utility model relates to the technical field of automotive films, and particularly relates to a high-gloss black automotive film with a laser-shaped pattern. Background Art

[0002] Simply put, a paint protection film is a transparent protective film applied to the automotive paint surface, also known as a car paint protection film. The product material is a polyurethane film containing anti-UV polymers, resistant to yellowing, with excellent toughness, abrasion resistance, easy adhesion, and scratch resistance. After installation, it can isolate the automotive paint surface from the air, prevent acid rain, oxidation, and resist scratches, providing long-term protection for the car paint surface.

[0003] Currently, a Chinese patent with the patent application number "CN202321794608.7" discloses an automotive black film, which includes a clear coat layer, a PVC film layer, and a pressure-sensitive adhesive layer arranged in layers in sequence. An air-permeable structure is provided on the outer side of the pressure-sensitive adhesive layer. The air-permeable structure includes a plurality of air-permeable grooves one and air-permeable grooves two, which are arranged crosswise. The head and tail ends of the air-permeable grooves one and air-permeable grooves two penetrate through the pressure-sensitive adhesive layer. The total thickness of the clear coat layer and the PVC film layer is 100 - 120 μm, the thickness of the pressure-sensitive adhesive layer is 30 - 50 μm, and the depth of the air-permeable grooves one and air-permeable grooves two does not exceed half of the thickness of the pressure-sensitive adhesive layer.

[0004] However, during the implementation of the above technical solution, it is found that at least the following technical problems exist:

[0005] Unable to decorate: The existing automotive black film has a uniform and unified surface color and does not have any patterns. For this reason, after the black film is installed, the vehicle body cannot display colors or patterns other than black. However, in actual use, in order to increase the recognition rate, vehicles require the car film to have a variety of complex and beautiful patterns, which is a major reason restricting the use range of the black film. As Figure 5 shown, for this reason, we propose a high-gloss black automotive film with a laser-shaped pattern. Utility Model Content

[0006] (1) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art, the utility model provides a high-gloss black automotive film with a laser-shaped pattern, which solves the technical problem that the existing automotive black film cannot play a decorative role because it does not have patterns during use.

[0008] (2) Technical Solutions

[0009] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0010] An automotive high-gloss black film with a laser-shaped pattern. The black film includes a transparent protective film, a high-gloss coating, a black film layer, and an adhesive layer arranged in sequence from top to bottom. Among them, when the black of the black film is exposed to light, the film at the position of the black film does not change, but the color on the film is decomposed, just like the situation where a normal outdoor billboard fades over time. Therefore, we utilize this characteristic and irradiate the black film with low-frequency cold light laser, causing the color of the black film layer to change (through laser etching, a state of dark-pattern silver flowers can be formed), thus forming an icon.

[0011] Preferably, the high-gloss coating is used to improve the brightness of the black film and prevent the surface of the black film from becoming dull. In addition, in order to prevent the high-gloss coating from oxidizing quickly, a protective film is connected to the outside of the high-gloss coating to isolate oxygen. In addition, in order not to affect the light of the high-gloss coating, a transparent material is selected for production.

[0012] Preferably, the bottom of the black film layer is coated with an adhesive layer, and a base paper is adhered to the surface of the adhesive layer to protect the adhesive layer through the base paper.

[0013] Preferably, the black film layer includes a black bottom film and a light-shielding film adhered to the surface of the black bottom film;

[0014] Among them, the light-shielding film is divided into two parts. One part is the connecting part, which is located between the high-gloss coating and the black bottom film and is used to connect the high-gloss coating and the black bottom film together;

[0015] The other part is the extending part, which is connected to both sides of the connecting part. In this way, when the surface temperature of the black film layer rises, the extending part expands and is guided to the position of the gap between two adjacent connecting parts, thereby covering the black bottom film. On the contrary, when it contracts due to cooling, the black bottom film covered by it is exposed.

[0016] (III) Beneficial effects

[0017] 1. Since the black film is made of PVC material and then acted on by low-frequency cold light laser, the color on the surface of the black film is decomposed and faded, thus forming various different-shaped patterns. Therefore, it effectively solves the technical problem that the existing automotive black film cannot play a decorative effect due to the lack of patterns on its own, and further realizes the decorative effect of the black film and improves the applicable range of the black film.

[0018] 2. Since the light-shielding film is made of a material that is easy to expand when heated, and an expansion space is reserved between the black film layer and the high-gloss coating. When the light-shielding film expands due to heat (in high-temperature summer), it covers the black film layer and fills the gap between the black film layer and the high-gloss coating, thereby improving the light-shielding effect of the black film; on the contrary, when the temperature drops (in low-temperature winter), the light-shielding film contracts, thus exposing the black bottom film and reducing the light absorption rate, thereby improving the light-transmitting effect of the black film.

[0026] In the embodiment of the present application, by providing an automotive high-gloss black film with a laser-shaped pattern, the technical problem that the existing automotive black film cannot play a decorative effect due to the lack of a pattern during use is effectively solved. When the existing automotive black film is used, since the black film is made of PVC material and then acted on by low-frequency cold light laser, the color on the surface of the black film is decomposed and faded, thereby forming various patterns of different shapes, and thus realizing the decorative effect of the black film and improving the application range of the black film; since the light-shielding film is made of a material that is easily expanded by heat and an expansion space is reserved between the black film layer and the high-gloss coating, when the light-shielding film expands due to heat (in hot summer), it covers the black film layer and fills the gap between the black film layer and the high-gloss coating, thereby improving the light-shielding effect of the black film; conversely, when the temperature drops (in cold winter), the light-shielding film shrinks, thereby exposing the black bottom film and reducing the light absorption rate, thereby improving the light transmittance of the black film.

[0027] Embodiment 1

[0028] The technical solution in the embodiment of the present application effectively solves the technical problem that the existing automotive black film cannot play a decorative effect due to the lack of a pattern during use. The general idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides an automotive high-gloss black film with a laser-shaped pattern. The black film includes a transparent protective film 1, a high-gloss coating 2, a black film layer, and an adhesive layer 4 arranged in sequence from top to bottom. Among them, the high-gloss coating 2 is used to improve the brightness of the black film and prevent the surface of the black film from being dull. In addition, in order to prevent the rapid oxidation of the high-gloss coating 2, a protective film is connected to the outside of the high-gloss coating 2 to isolate oxygen. In addition, in order not to affect the light of the high-gloss coating 2, a transparent material is selected for production.

[0030] For the adhesive layer 4 (glue layer) at the bottom of the black film layer, it is mainly used for subsequent bonding with the vehicle surface. However, in order to prevent the glue from being adhered by dust in the air or the black films to each other, a paper base paper 5 is sleeved outside it. When in use, it can be torn off and used directly. In order to solve the problem that traditional black films cannot display images, we use laser etching to process the black film, as follows:

[0031] Through daily observation, it can be seen that during normal use, the black color of the black film remains unchanged after being illuminated, but the color on the film is decomposed, just like the situation that an outdoor billboard fades after a long time. Therefore, we utilize this characteristic to irradiate the black film with low-frequency cold light laser, so that the color of the black film layer changes (through laser etching, a state of dark pattern silver flowers can be formed), which forms the icon 6. Moreover, by controlling the route of the low-frequency cold light laser, a specific-shaped pattern can be formed. And the material of the black film is all PVC film, thereby increasing the recognition of the vehicle and further expanding the application range of the black film.

[0032] Embodiment 2

[0033] Based on Embodiment 1, the embodiment of this application is that the black film can adjust its own light-shielding rate according to the temperature change situation. The general idea is as follows:

[0034] The black film layer in the black film is divided into two parts. One is the black bottom film 31 with an unchangeable shape; the other is the light-shielding film 32 that can expand when affected by high temperature. In order to maintain the light-shielding effect of the black film itself, the light-shielding film 32 is adhered to the surface of the black bottom film 31, as Figure 1 shown;

[0035] And the light-shielding film 32 is also divided into two parts. One part is the partial structure that cannot expand. This part of the structure (connection part) is located between the high-gloss coating 2 and the black bottom film 31, and the high-gloss coating 2 and the black bottom film 31 are connected together through this part, as Figure 1 shown, the part directly connected to the high-gloss coating 2 and the black bottom film 31;

[0036] Another part is a partial structure that is prone to expansion when heated. This partial structure (the connecting part) is located on the side wall of the non-expandable part. To facilitate the expansion of the connecting part, a cavity is formed between the high-gloss coating 2 and the black bottom film 31. As Figures 1-4 shown, in this way, when the surface temperature of the black film layer rises, the extension part can expand and be guided towards the position of the gap between two adjacent connecting parts, so as to cover the black bottom film 31, as Figure 3 and Figure 4 shown. On the contrary, when it contracts due to cooling, the black bottom film 31 covered at the bottom of the light-shielding film 32 will be exposed.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples given for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
