Description

Technical Field

[0001] The utility model relates to the technical field of PET films, and particularly relates to a novel PET film structure. Background Art

[0002] The PET film is also known as a high-temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in the fields of magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging and decoration, screen protection, optical-grade mirror surface protection, etc.

[0003] The existing PET films applied to the screens of electronic devices (such as mobile phones, iPads, etc.) generally have an anti-fingerprint layer, a waterproof layer, an elastic layer, and a base layer. This kind of PET film structure is simple and does not have the functions of anti-blue light and anti-impact protection. Therefore, how to design a PET film structure with anti-blue light and anti-impact functions has become an urgent technical problem to be solved. Summary of the Utility Model

[0004] In order to overcome the existing technical defects, the purpose of the utility model is to provide a novel PET film structure to solve the above technical problems.

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

[0006] According to one aspect of the utility model, a novel PET film structure is designed, including: an anti-fingerprint coating, an anti-blue light coating, a first carbon nanotube layer, an elastic layer, and a base layer, which are arranged in sequence from top to bottom. The thickness of the first carbon nanotube layer is 0.22 - 0.32 mm, and the thickness of the elastic layer is 0.25 - 0.35 mm.

[0007] By adopting the above technical solution, by setting an anti-blue light coating in the PET film, the effect of anti-blue light can be achieved. By setting a first carbon nanotube layer above the elastic layer, the strength and anti-impact performance of the PET can be improved. By setting reasonable thicknesses of the carbon nanotube layer and the elastic layer, while the PET film has good anti-impact performance, the thickness of the PET film is compressed as much as possible, making the overall thickness relatively thin.

[0008] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0009] In some embodiments, a protective layer is adhered to the bottom of the base layer.

[0010] In some embodiments, one end of the bottom of the protective layer is connected with a double-sided adhesive layer, the double-sided adhesive layer is connected with a tearing piece, and the tearing end of the tearing piece is bent 180° at the crease position to the inner side range of the edge of the protective layer. The tearing piece is used to tear off the protective layer when the PET film needs to be used. The tearing end of the existing tearing piece protrudes to the outside of the edge of the protective layer. When the PET film is produced and needs to be packaged, due to the protrusion of one end of the tearing piece, a large packaging box is required for packaging, increasing the production cost. By setting a crease on the tearing piece, the tearing end thereof can be bent 180° to the inner side of the edge of the protective layer, so that the outer contour size of the PET film product can be reduced and the production cost can be lowered.

[0011] In some embodiments, the elastic layer is a thermoplastic polyurethane layer with a thickness of 0.3 mm, and the thickness of the first carbon nanotube layer is 0.25 mm.

[0012] In some embodiments, the base layer is a TUP layer.

[0013] In some embodiments, the protective layer is a release film.

[0014] In some embodiments, a waterproof layer is provided between the elastic layer and the base layer.

[0015] In some embodiments, an ITO layer is provided between the anti-blue light coating and the carbon nanotube layer.

[0016] In some embodiments, a second carbon nanotube layer is provided between the elastic layer and the waterproof layer, and the thickness of the second carbon nanotube layer is 0.2 - 0.28 mm. BRIEF DESCRIPTION OF THE DRAWINGS
