Description

Novel double-layer toughened film

Technical Field

The invention relates to a toughened film, in particular to a novel double-layer toughened film.

Background

At present, toughened glass films in the market are all of a one-layer structure, and need to be replaced after being broken. Consumers often need to buy the toughened glass film again, and the mobile phone screen is easy to break without any protection in the process of buying and waiting for a new toughened glass film. Of course, some consumers may purchase multiple toughened glass films at the same time, but the toughened glass films are not easy to find when needed, and are more wasted. In addition, in the process of using the toughened glass film by some consumers, due to unskilled film pasting or misoperation, film pasting failure can be caused, and the toughened glass film is scrapped due to one-time film pasting failure of the existing products, so that the waste of funds and product resources of the consumers is caused.

In order to solve the defects, the utility model provides a novel double-layer toughened film, even if the first layer is broken, the second layer can be used continuously; even if the first film sticking fails, the second layer can be torn off and the first layer can be used for continuously sticking the film. The toughened glass film is easy to break, and is usually subjected to instantaneous impact force or is collided with sand grains on the ground when falling on the ground, but the external force is released when the toughened glass film is broken, so that the screen of the mobile phone cannot be further damaged. In the same way, the utility model provides a novel double-deck tempering membrane, broken destruction external force in the twinkling of an eye of first layer toughened glass membrane has obtained the release, and can not further damage second polymer material tempering rete. The clean incomplete foreign matter of remaining of screen, dirt point, dirty etc. cause the pad pasting failure easily to the tempering membrane pad pasting appears to can harm the tempering membrane and lead to the tempering membrane can not continue to use with the silica gel layer of screen pasting and scrap, the utility model provides a novel double-deck tempering membrane, using the first pad pasting of second floor, can continue to use first layer continuation pad pasting, resources are saved.

Disclosure of Invention

The utility model provides a novel double-deck tempering membrane, include from last to the first toughened glass rete, first adhesive layer, the second polymer material tempering rete that set gradually down and from the type rete, its characterized in that, first adhesive layer pastes the lower surface at first toughened glass rete, the lower surface at first adhesive layer is pasted to second polymer material tempering rete.

Furthermore, the first adhesive layer is an AB optical adhesive layer, and the AB optical adhesive layer is respectively attached to the lower surface of the first toughened glass film layer and the upper surface of the second polymer toughened film layer.

Furthermore, AB optics glue film is from last to having set gradually OCA optics glue film, PET substrate, silica gel layer down. Wherein, OCA optical cement layer viscosity is greater than the silica gel layer, because OCA optical cement layer and toughened glass rete are laminated mutually and need great adhesion, and the silica gel layer directly with the cell-phone screen relatively little adhesion of laminating mutually can.

Further, the second polymer material toughened film layer contains a polymer base material and a silica gel structure.

Further, the polymer substrate includes, but is not limited to, high polymer materials such as TPU/PET/PMMA, etc.

Furthermore, the viscosity of the first adhesive layer is less than that of the silica gel of the second polymer material toughened film layer, and the viscosity is the stripping force. Because the setting of this kind of viscosity difference, can avoid second polymer material toughened rete to take off earlier than first layer toughened glass membrane on the one hand, on the other hand can be after first toughened glass membrane breaks into pieces, more easily peel off first layer toughened glass membrane and second polymer material toughened rete.

Preferably, the thickness of the first toughened glass film layer is 0.1-0.33 mm.

Preferably, the thickness of the second polymer material toughened film layer is 0.05-0.2 mm.

Furthermore, a nano silicon scratch-resistant layer is arranged on the upper surface of the toughened film and coated on the upper surface of the toughened film. The toughened film comprises a first toughened glass film and a second high polymer toughened film.

The utility model has the advantages that the utility model provides a novel double-layer toughened film, even if the first layer is broken, the second layer can be used continuously; even if the second layer of adhesive film fails to be used once, the first layer of adhesive film can be used for continuous application. In addition, adopt different adhesion power promptly peeling strength between the AB optical adhesive layer of the first adhesive layer of first toughened glass film lower surface and the silica gel of second polymer material tempering rete respectively, the first layer has broken into pieces, also makes things convenient for first toughened glass film and the separation of second layer protection film.

Detailed Description

The invention is further described below with reference to the figures and examples.

Example 1

As shown in fig. 1-2, the utility model provides a novel double-deck tempering membrane, include from last to the first toughened glass rete 1, first adhesive layer 2, the second polymer material tempering rete 3 that set gradually extremely down and from type rete 4, its characterized in that, the lower surface at first toughened glass rete 1 is pasted to first adhesive layer 2, the lower surface at first adhesive layer 2 is pasted to second polymer material tempering rete 2.

Further, the first adhesive layer is an AB optical adhesive layer, and the AB optical adhesive layer is respectively attached to the lower surface of the first toughened glass film and the upper surface of the second polymer toughened film layer.

Furthermore, AB optics glue film is from last to having set gradually OCA optics glue film, PET substrate, silica gel layer down. Wherein, OCA optical cement layer viscosity is greater than the silica gel layer, because OCA optical cement layer and toughened glass membrane laminating need great adhesion mutually, and the silica gel layer is direct with the cell-phone screen laminating less adhesion mutually can.
