Description

Anti-oil and hot pressure protective film

technical field

The utility model relates to the technical field of mobile phone protective films, in particular to an oil-pollution-proof thermal-press protective film.

Background technique

With the continuous advancement of science and technology, more and more touch panels are used in display devices, but the passive wear of the touch panel will lead to the reduction of performance and aesthetics, and eventually lead to the loss of its use value and economic losses. Therefore, the hard coating that can be applied to the surface of the substrate has become the current research.

Although the highly transparent liquid crystal protective films currently on the market have a good anti-scratch effect, their anti-oil and fingerprint performance is very poor. When in use, the protective film is easily stained by grease or sweat from the user's fingers to leave fingerprints, and is easily scratched, affecting the clarity of the screen.

Utility model content

In view of the above deficiencies, the purpose of this utility model is to provide an ingenious and reasonable structural design, anti-scratch, and hydrophobic and oil-repellent, good cleaning effect and anti-oily hot-pressing protective film.

In order to achieve the above purpose, the utility model provides a technical solution as follows: an oil-stain-resistant hot-pressing protective film, which includes a protective layer, a use layer and a release layer that are laminated sequentially from top to bottom. The layer includes a PET protective film layer and an adhesive layer that are sequentially pasted from top to bottom, and the use layer includes an acrylic varnish layer, a high-transparency PET film layer and a high-transparency layer that are sequentially pasted from top to bottom. Silica gel layer, the release layer is a fluorine release film.

As an improvement of the utility model, the thickness of the PET protective film layer is 45-55 microns.

As an improvement of the utility model, the adhesive layer is a silica gel layer.

As an improvement of the utility model, the thickness of the adhesive layer is 8-12 microns.

As an improvement of the utility model, the thickness of the acrylic varnish layer is 2-6 microns.

As an improvement of the utility model, the thickness of the high-permeability PET film layer is 16-20 microns.

As an improvement of the utility model, the thickness of the high permeability silica gel layer is 36-44 microns.

As an improvement of the utility model, the thickness of the fluorine release film is 45-55 microns.

The beneficial effects of the utility model are as follows: the utility model has a reasonable structural design, and the protective layer effectively protects the use layer from being scratched or damaged by external forces before use, thereby ensuring product quality; the high-permeability PET film layer in the use layer is coated with With acrylic varnish layer, hydrophobic and oil-repellent, easy to wipe the surface without oil or water residue, also play a role in hardening the PET surface, anti-oil, good cleaning effect; high-transparency PET film layer has strong toughness, is not easy to break, wear-resistant, safe Reliable, through the high-permeability silica gel layer, it can be smoothly adsorbed on the surface of the object to be pasted, which is convenient for operation and sticking. At the same time, the fluorine release film can keep the surface of the high-permeability silica gel layer clean and avoid sticking other sundries , and is easy to peel off, brings convenience to use, strong practicability, and is conducive to wide popularization and application.

detailed description

Embodiment: Referring to Fig. 1, an embodiment of the present invention provides an oil-stain-resistant hot-pressing protective film, which includes a protective layer 1, a use layer 2 and a release layer 3 that are laminated sequentially from top to bottom. The protective layer 1 includes a PET protective film layer 11 and an adhesive layer 12 that are laminated sequentially from top to bottom, and the use layer 2 includes an acrylic varnish layer 21 that is laminated sequentially from top to bottom, a high-transparency PET film layer 22 and high permeability silica gel layer 23, the release layer 3 is a fluorine release film. An anti-blue light PET film layer (not shown in the figure) can also be pasted on the upper surface of the high-transparency PET film layer 22 by OCA glue, which not only has the anti-blue light effect, but also can further improve the explosion-proof effect.

Specifically, the thickness of the PET protective film layer 11 is 45-55 microns, preferably 50 microns. The adhesive layer 12 is preferably a silica gel layer. The thickness of the adhesive layer 12 is 8-12 microns, preferably 10 microns. The thickness of the acrylic varnish layer 21 is 2-6 microns, preferably 4 microns. The thickness of the high-transparency PET film layer 22 is 16-20 microns, preferably 18 microns. The thickness of the high permeability silica gel layer 23 is 36-44 microns, preferably 40 microns. The thickness of the fluorine release film is 45-55 microns, preferably 50 microns.

Before use, the protective layer 1 and the release layer 3 effectively protect the use layer 2 from being scratched or damaged by external force before use, so as to ensure product quality. When pasting, the release layer 3 is peeled off, and the high-permeability silica gel layer 23 can be smoothly adsorbed on the surface of the object to be pasted, and can be automatically exhausted, and the operation is convenient. When in use, because the high-permeability PET film layer 22 of the use layer 2 is coated with an acrylic varnish layer 21, which is hydrophobic and oil-repellent, it is easy to wipe the surface without oil or water residue, and also plays the role of hardening the PET surface, preventing oil and cleaning. Good; the high-transparency PET film layer 22 has strong toughness, is not easy to break, is wear-resistant, and is safe and reliable.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also change and modify the above embodiment. Therefore, the utility model is not limited to the specific implementation manners disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention. The use of other protective films that are the same or similar to them are all within the protection scope of the present invention.
