Description

Technical Field

[0001] The utility model belongs to the field of car cover films, relates to PVC car cover film technology, and specifically is a PVC self-repairing color-changing car cover film structure. Background Art

[0002] Self-repairing and color-changing car film is a film that is applied to the surface of a vehicle to prevent scratches, prevent foreign objects from contaminating the paint, improve the appearance of the vehicle, and meet personalized needs.

[0003] In the existing technology, PVC self-repairing and color-changing car cover films can be mainly divided into two types: one is calendered PVC color-changing film, and the other is cast PVC color-changing film. Among them, cast PVC color-changing film mainly includes a protective film, a self-repairing film, a colored layer, a PVC layer, and a release film layer, which are laminated in sequence. In order to improve the bonding strength, a thicker adhesive layer is usually required between the colored layer and the PVC layer to assist in bonding. However, the thicker adhesive layer will increase the overall thickness of the color-changing film, thus affecting the overall aesthetics.

[0004] Therefore, a PVC self-repairing color-changing car cover film structure is needed to ensure the bonding strength while reducing the overall thickness of the color-changing film and improving the overall aesthetics. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a PVC self-repairing color-changing car cover film structure, which can effectively reduce the overall thickness of the color-changing film while ensuring the bonding strength, thereby improving the overall aesthetics. The present invention is provided with a plurality of protrusions and recessed portions corresponding to the protrusions on the side where the colored layer and the PVC layer are close to each other, and UV colloid is provided at the junction of the protrusions and the recessed portions, that is, the rapid combination of the protrusions and the recessed portions is achieved by means of light curing, and since the protrusions and the recessed portions are embedded in the connection, the thickness formed when the traditional glue layer is combined can be avoided, thereby achieving the purpose of effectively reducing the overall thickness of the color-changing film while ensuring the bonding strength and improving the overall aesthetics.

[0006] To achieve the above-mentioned purpose, the first aspect of the present invention provides a PVC self-repairing color-changing car cover film structure, comprising a protective layer, a self-repairing coating, a colored layer, a PVC layer and a release film adhesive layer arranged in sequence from top to bottom;

[0007] The colored layer and the PVC layer have a plurality of protrusions extending along the outside and recesses matching the protrusions on the side close to each other;

[0008] The convex portion and the concave portion are connected in an embedded manner, and UV colloid is provided at the connection point.

[0009] Furthermore, the cross-sectional area of ​​the raised portion decreases gradually as it approaches the recessed portion.

[0010] Furthermore, the raised portion is configured as a truncated cone structure.

[0011] Furthermore, the raised portion is configured as a prism-shaped structure.

[0012] Furthermore, the outer wall of the raised portion is provided with a glue storage groove for accommodating the overflowed UV colloid.

[0013] Furthermore, the glue storage groove includes a plurality of annular grooves arranged around the protruding direction of the protruding portion.

[0014] Furthermore, the glue storage tank is arranged in a spiral structure.

[0015] Furthermore, the depth of the recessed portion is one third to one half of the thickness of the PVC layer.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By arranging multiple protrusions and recessed portions corresponding to the protrusions on the side where the colored layer and the PVC layer are close to each other, and arranging UV colloid at the junction of the protrusions and the recessed portions, that is, light curing is used to achieve rapid combination of the protrusions and the recessed portions, and since the protrusions and the recessed portions are embedded in the connection, the thickness formed when the traditional glue layer is combined can be avoided, thereby achieving the purpose of effectively reducing the overall thickness of the color-changing film while ensuring the bonding strength and improving the overall aesthetics.

[0018] Furthermore, by providing a glue storage tank on the outside of the raised part, when the raised part and the recessed part are docked, the UV colloid can be immersed into the glue storage tank, and then when the UV colloid is light-cured, it can further limit the raised part and the recessed part in the direction of mutual docking, thereby achieving the purpose of further improving the bonding strength between the colored layer and the PVC layer.

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 and Figure 2 As shown, the first embodiment of the utility model provides a PVC self-repairing and color-changing car cover film structure, including a protective layer 1, a self-repairing coating 2, a colored layer 3, a PVC layer 4 and a release film adhesive layer 5 arranged in sequence from top to bottom.

[0028] It should be noted that the self-healing coating 2 is a self-healing coating known in the prior art. Specifically, self-healing coatings can be roughly divided into three types based on their repair mechanisms: 1. Healing agent-releasing self-healing coating layers; 2. Reversible chemical / physical reaction self-healing coating layers; and 3. Other types.

[0029] The repair agent-releasing self-repairing coating layer mainly includes: 1. microcapsule self-repairing coating layer; 2. liquid core / hollow fiber self-repairing coating layer; 3. redox reaction self-repairing coating layer.

[0030] The reversible chemical / physical reaction self-repairing coating layer mainly includes: 1. Reversible reaction self-repairing coating layer; 2. Shape memory self-repairing coating layer (mainly for polyurethane).

[0031] The self-repairing coating 2 proposed in the present invention can adopt any one of the self-repairing coating layers proposed above.

[0032] Among them, the colored layer 3 and the PVC layer 4 have a plurality of protrusions 31 extending along the outside and recessed portions 41 matching the protrusions 31 on one side close to each other, that is, the bonding strength between the colored layer 3 and the PVC layer 4 is improved by the embedded connection of the protrusions 31 and the recessed portions 41, so as to replace the bonding method using the adhesive layer in the prior art, thereby avoiding the thickness formed by the adhesive layer between the colored layer 3 and the PVC layer 4, thereby achieving the purpose of ensuring the bonding strength between the two while effectively reducing the overall thickness of the color-changing film and improving the overall aesthetics.

[0033] In addition, to ensure the stability of the embedded connection between the raised portion 31 and the recessed portion 41, a UV gel 6 is added. Specifically, the raised portion 31 and the recessed portion 41 are embedded and connected, and the UV gel 6 is provided at the connection. The UV gel 6 is disposed between the raised portion 31 and the recessed portion 41, and can be cured by light, thereby achieving rapid bonding between the raised portion 31 and the recessed portion 41 and improving the bonding speed.

[0034] It should be noted that the UV colloid 6 is always located in the recessed portion 41 , that is, it will not overflow, thereby ensuring that bubbles are not generated due to the overflow of the UV colloid 6 when the colored layer 3 and the PVC layer 4 are combined.

[0035] This device is achieved by respectively arranging a plurality of raised portions 31 and recessed portions 41 corresponding to the raised portions 31 on one side where the colored layer 3 and the PVC layer 4 are close to each other, and arranging a UV glue 6 at the junction of the raised portions 31 and the recessed portions 41, that is, using light curing to achieve rapid combination of the raised portions 31 and the recessed portions 41, and because the raised portions 31 and the recessed portions 41 are embedded in the connection, the thickness formed when the traditional glue layer is combined can be avoided, thereby achieving the purpose of effectively reducing the overall thickness of the color-changing film while ensuring the bonding strength and improving the overall aesthetics.

[0036] In a further embodiment, in order to facilitate the embedded connection between the protrusion 31 and the recess 41 , the shape of the protrusion 31 is further limited.

[0037] Specifically, the cross-sectional area of ​​the raised portion 31 decreases gradually as it approaches the recessed portion 41, so that the top opening diameter of the recessed portion 41 is larger than the bottom opening diameter. Therefore, when the raised portion 31 is docked with the recessed portion 41, even if the axis centers of the raised portion 31 and the recessed portion 41 are not located in the same vertical plane, the embedded docking can still be completed under the inclined guiding action of the inner wall of the recessed portion 41, thereby achieving the purpose of facilitating embedded connection.

[0038] like Figure 4As shown, in one example, the protrusion 31 is configured as a truncated cone structure, and the outer wall of the protrusion 31 is provided with a glue storage groove 7 for accommodating the overflowed UV glue 6.

[0039] like Figure 2 As shown, the glue storage tank 7 includes a plurality of annular grooves arranged around the protruding direction of the protruding portion 31, so that when the UV colloid 6 is light-cured and bonded, the protruding portion 31 can be limited by the annular grooves, so that the protruding portion 31 cannot be separated from the recessed portion 41 along its protruding direction, thereby achieving the purpose of improving the bonding stability of the colored layer 3 and the PVC layer 4.

[0040] like Figure 3 and Figure 4 As shown, in a further example, the glue storage groove 7 is provided in a spiral structure, and it can also be limited along the protruding direction of the protrusion 31, and by providing the glue storage groove 7 in a spiral shape, processing is facilitated.

[0041] In another example, the protrusion 31 is configured as a prism-shaped structure to increase the contact area between the UV colloid 6 and the protrusion 31 and the recessed portion 41 , thereby further improving the connection strength.

[0042] In this embodiment, the depth of the recessed portion 41 is one third to one half of the thickness of the PVC layer 4 .

[0043] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
