Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a bending-resistant protective film for rolling shutter doors. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. In a fixed slideway, the doors rotate up and down with the reel above the door as the center. Rolling shutter doors are widely used in shops. Like walls, rolling shutter doors play the role of horizontal partitions. They are composed of curtain plates, seat plates, guide rails, supports, reels, boxes, control boxes, rolling door machines, limiters, door lintels, manual quick-release switch devices, push button switches and safety devices. They are generally installed in places where it is inconvenient to use walls for partitions.

[0003] The surface of the rolling shutter door is provided with a protective film, which can isolate the rolling shutter door from water vapor, thereby effectively protecting the protective film.

[0004] The protective films of existing rolling shutter doors are directly attached to the rolling shutter door or bonded to the rolling shutter door by glue. When the rolling shutter is rolled up, the rolling shutter door and the protective film are bent together. However, the rolling shutter door is made of hard material, while the protective film is made of soft material. Therefore, the bending force applied to the protective film and the bending force applied to the rolling shutter door are different in direction and stress. Therefore, the protective film is easily separated from the rolling shutter door, resulting in a gap between the protective film and the rolling shutter door, which cannot effectively isolate water vapor and cannot effectively protect the rolling shutter door. Utility Model Content

[0005] In view of the problems existing in the existing anti-bending protective film of rolling shutter door, the utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a bending-resistant protective film for rolling shutter doors, which solves the problem that the protective films of existing rolling shutter doors are directly attached to the rolling shutter doors or bonded to the rolling shutter doors by glue. When the rolling shutter is rolled up, the rolling shutter door and the protective film are bent together. However, the rolling shutter door is made of hard material, while the protective film is made of soft material. Therefore, the bending force applied to the protective film and the bending force applied to the rolling shutter door are different in direction and stress. Therefore, the protective film is easily separated from the rolling shutter door, resulting in a gap between the protective film and the rolling shutter door, thereby failing to isolate water vapor well and thus failing to protect the rolling shutter door well.

[0007] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0008] A bending-resistant protective film for a rolling door comprises an outer film layer of the protective film, one side of the outer film layer of the protective film is bonded with an elastic layer, and the other side of the elastic layer is provided with an adhesive structure, which can be bonded to the surface of the rolling door by using the adhesive structure.

[0009] As a preferred solution of the bending-resistant protective film for rolling shutter doors described in the utility model, the outer film layer and the elastic layer of the protective film are bonded together by glue, and a first adhesive layer is formed between the outer film layer and the elastic layer of the protective film.

[0010] As a preferred solution of the anti-bending protective film for rolling shutter doors described in the utility model, the bonding structure is composed of a second bonding layer and easy-tear paper, and the second bonding layer and the easy-tear paper are bonded together.

[0011] As a preferred solution of the bending-resistant protective film for rolling shutter doors described in the utility model, the outer film layer of the protective film is set as a polyester film or a polyethylene film.

[0012] As a preferred solution of the anti-bending protective film for rolling shutter doors described in the utility model, wherein: the first adhesive layer and the second adhesive layer are both set as water-based glue.

[0013] As a preferred solution of the anti-bending protective film for rolling shutter doors described in the utility model, the elastic layer is made of rubber material.

[0014] As a preferred solution of the anti-bending protective film for rolling shutter doors described in the utility model, the side of the elastic layer away from the second adhesive layer is sprayed with paint to form a paint layer.

[0015] Compared with existing technologies:

[0016] 1. By setting an elastic layer of rubber material, the elastic layer of rubber material is softer than the rolling door, so it can bend with the rolling door. However, the elastic layer is harder than the outer film layer of the protective film. Therefore, when the outer film layer of the protective film is bent with the rolling door, the stress magnitude and direction of the bending of the outer film layer are closer to the stress magnitude and direction of the bending of the rolling door. Therefore, it is not easy to separate from the rolling door, and it is not easy to generate a gap, so as to achieve a better anti-bending effect and a good protective effect;

[0017] 2. The shape of the protective film is the same as that of the rolling door, so that it can fit better with the rolling door. Compared with the existing smooth protective film, it can be easier to set on the rolling door and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] The utility model provides a bending-resistant protective film for rolling shutter doors. Figure 1-2 The shape of the protective film is the same as that of the rolling door, so that it can better fit with the rolling door. Compared with the existing smooth protective film, it is not troublesome to bend the protective film a little bit to fit with the rolling door. It can be easier to be set on the rolling door and is more convenient to use. It includes a protective film outer film layer 3, and the protective film outer film layer 3 is set as a polyester film or a polyethylene film. An elastic layer 1 is bonded to one side of the protective film outer film layer 3, and the elastic layer 1 is set as a rubber material. The other side of the elastic layer 1 is provided with a bonding structure, which can be bonded to the surface of the rolling door using the bonding structure. Specifically, the The bonding structure is composed of a second bonding layer 4 and an easy-tear paper 5, and the second bonding layer 4 and the easy-tear paper 5 are bonded together; the elastic layer 1 of rubber material is softer than the rolling door, so it can bend with the rolling door, but the elastic layer 1 is harder than the outer film layer 3 of the protective film, so when the outer film layer 3 of the protective film is bent with the rolling door, the bending stress magnitude and direction of the outer film layer 3 are closer to the bending stress magnitude and direction of the rolling door, so it is not easy to separate from the rolling door, and thus it is not easy to produce a gap, thereby achieving a better anti-bending effect and a good protective effect.

[0023] The easy-tear paper 5 is torn off, so that the protective film can be adhered to the rolling door using the second adhesive layer 4, thereby making the installation of the protective film more convenient.

[0024] The protective film outer layer 3 and the elastic layer 1 are bonded together by glue, and a first bonding layer 2 is formed between the protective film outer layer 3 and the elastic layer 1. The first bonding layer 2 and the second bonding layer 4 are both set to water-based glue, and the water-based glue is a self-adhesive glue, so it has better ductility. Therefore, when the rolling shutter door is bent, it is easy to bend with the rolling shutter door, and it is not easy to separate from the rolling shutter door.

[0025] When in use, the easy-tear paper 5 is torn off, so that the protective film can be bonded to the rolling door using the second adhesive layer 4, making the installation of the protective film more convenient. The shape of the protective film is the same as that of the rolling door, so that it can better fit the rolling door. Compared with the existing smooth protective film, it is not troublesome to bend the protective film a little bit to fit the rolling door, so it can be more easily set on the rolling door and is more convenient to use.

[0026] The texture of the elastic layer 1 made of rubber material is softer than that of the rolling door, so it can bend with the rolling door. The texture of the elastic layer 1 is harder than that of the protective film outer film layer 3. Therefore, when the protective film outer film layer 3 is bent with the rolling door, the bending stress magnitude and direction of the outer film layer 3 are closer to the bending stress magnitude and direction of the rolling door. Therefore, it is not easy to separate from the rolling door, and it is not easy to produce a gap, thereby achieving a better anti-bending effect and a good protective effect.

[0027] Embodiment 2: The difference from Embodiment 1 is that paint is sprayed on the side of the elastic layer 1 away from the second adhesive layer 4 to form a paint layer; the paint layer is used to color the elastic layer 1, so that the protective film can be produced in a desired color to meet the needs of people with different color preferences.

[0028] When in use, the easy-tear paper 5 is torn off, so that the protective film can be bonded to the rolling door using the second adhesive layer 4, making the installation of the protective film more convenient. The shape of the protective film is the same as that of the rolling door, so that it can better fit the rolling door. Compared with the existing smooth protective film, it is not troublesome to bend the protective film a little bit to fit the rolling door, so it can be more easily set on the rolling door and is more convenient to use.

[0029] The texture of the elastic layer 1 made of rubber material is softer than that of the rolling door, so it can bend with the rolling door. The texture of the elastic layer 1 is harder than that of the protective film outer film layer 3. Therefore, when the protective film outer film layer 3 is bent with the rolling door, the bending stress magnitude and direction of the outer film layer 3 are closer to the bending stress magnitude and direction of the rolling door. Therefore, it is not easy to separate from the rolling door, and it is not easy to produce a gap, thereby achieving a better anti-bending effect and a good protective effect.

In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
