For example, the elasticity of the composite adhesive film is poor, and it is difficult to achieve a buffering and protective effect once the composite adhesive film is squeezed, thus unable to protect the laminated article. Moreover, the anti-corrosion effect of some composite adhesive films is poor, and the service life of the composite adhesive film is short.

[0004] There is an urgent need for a corrosion-resistant elastic thin composite adhesive film to solve the technical defects mentioned in the above technology. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-4, A corrosion-resistant elastic thin composite adhesive film, comprising a composite adhesive film main body 1.

A aluminized layer 8 is fixedly connected to the bottom of the composite adhesive film main body 1. An anti-corrosion coating 9 is provided at the bottom of the aluminized layer 8. A positioning patch 10 is fixedly adhered to the bottom of the anti-corrosion coating 9. A buffer assembly is provided between the composite adhesive film main body 1 and the tensile layer 2;

[0026] The buffer assembly includes a buffer cavity 5. The buffer cavity 5 is arranged between the composite adhesive film main body 1 and the tensile layer 2. Elastic buffer pads 6 are arranged inside the buffer cavity 5. Elastic connection layers 7 are arranged on both sides of the elastic buffer pads 6;

[0027] The top of the elastic buffer pad 6 is fixedly connected to the bottom of the tensile layer 2. The bottom of the elastic buffer pad 6 is fixedly connected to the top of the composite adhesive film main body 1. The elastic buffer pads 6 and the elastic connection layers 7 are evenly distributed inside the buffer cavity 5;

[0028] Specifically, as Figure 1 and Figure 4 shown, the buffer cavity 5 has the effect of buffer protection. During the use of the composite adhesive film main body 1, once the composite adhesive film main body 1 is squeezed, the elastic buffer pads 6 and the elastic connection layers 7 inside the buffer cavity 5 can undergo a certain degree of elastic deformation to achieve buffer protection and reduce the damage to the composite adhesive film main body 1 caused by extrusion.

[0029] Embodiment 2: Positioning chutes 13 are provided on both sides and the two sides of the top of the appearance layer 4. A first positioning block 14 is fixedly connected to one side inside the connection groove 12. A second positioning block 15 is fixedly connected to the top inside the connection groove 12. The edge of the appearance layer 4 is embedded inside the connection groove 12. Both the first positioning block 14 and the second positioning block 15 are embedded inside the positioning chute 13. The appearance layer 4 and the connection groove 12 are adhered by glue. The appearance layer 4 is made of a waterproof material;

[0030] Specifically, as Figure 1 and Figure 3 shown, when connecting the appearance layer 4, the two sides need to be first embedded inside the connection groove 12 and limited and fixed by the first positioning block 14 and the second positioning block 15, and then the two ends of the appearance layer 4 are adhered to the waterproof layer 3 with glue. The range of glue adhesion becomes smaller, which is convenient for replacing the appearance layer 4. After the appearance layer 4 is removed, other appearance layers 4 can be adhered to achieve the function of repeated use.

[0031] Embodiment 3: Four groups of positioning patches 10 are provided. The positioning patches 10 are installed at the four corners at the bottom end of the anti-corrosion coating 9. A positioning strip 11 is fixedly connected between the positioning patches 10.

[0032] Specifically, as Figure 1 and Figure 2 shown, both the waterproof layer 3 and the appearance layer 4 made of waterproof material can achieve the waterproof effect, preventing moisture from penetrating the wrapping paper and wetting the interior when the composite film body 1 is in use. The aluminized layer 8 of the composite film body 1 can prevent water vapor from passing through, avoiding the problem of the composite film body 1 getting damp and mildewing. The anti-corrosion coating 9 at the bottom of the composite film body 1 is applied with an anti-corrosion agent, which can delay the time of deterioration.

[0033] Working principle: When the present utility model is in use, it is necessary to first install the composite film body 1 on the designated article. The positioning patches 10 and the positioning strip 11 of the composite film body 1 can achieve the effect of positioning packaging. When connecting the appearance layer 4, the two sides need to be first embedded inside the connecting groove 12 and limited and fixed by the first positioning block 14 and the second positioning block 15, and then glue is used to bond the two ends of the appearance layer 4 to the waterproof layer 3. The range of glue bonding becomes smaller, which is convenient for replacing the appearance layer 4. After the appearance layer 4 is removed, it can adhere to other appearance layers 4 to achieve the function of repeated use. The buffer cavity 5 at the top of the composite film body 1 has the effect of buffer protection. During the use of the composite film body 1, once the composite film body 1 is squeezed, the elastic buffer pads 6 and the elastic connection layer 7 inside the buffer cavity 5 can undergo a certain degree of elastic deformation to achieve buffer protection, reducing the damage to the composite film body 1 caused by extrusion. The waterproof layer 3 can prevent moisture from penetrating the composite film body 1 and wetting the interior. The aluminized layer 8 of the composite film body 1 can prevent water vapor from passing through, avoiding the problem of the composite film body 1 getting damp and mildewing during use. The anti-corrosion coating 9 at the bottom of the composite film body 1 is applied with an anti-corrosion agent, which can delay the deterioration time of the composite film body 1 and extend the service life of the composite film body 1.
