Description

Anti-cracking toughened film

Technical Field

The invention relates to a toughened film technology, in particular to an anti-cracking toughened film.

Background

The protective film can be divided into a digital product protective film, an automobile protective film, a household protective film, a food fresh-keeping protective film and the like according to the application. At present, most of digital products adopt a rear toughened screen cover and a front cover, and when the digital products fall to the ground, the back of the toughened screen is extremely easy to damage, so that a special toughened screen back protective film needs to be attached to the back of the toughened screen.

The protective film is mainly used on the screen of the mobile phone, the rear covers of some mobile phones use the toughened screen backs, the protective film needs to be attached to the rear covers of the mobile phones for protection, most of the existing protective films for the toughened screen backs of the mobile phones are manufactured for preventing the falling of the ground from being damaged, the conventional toughened film protective layers are good in use hand feeling and popular with users, but the protective films are easy to break, cracks and the like occur, the use effect of the users is seriously influenced, and the problem that the protective films are urgently needed to solve at present is solved.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the anti-cracking toughened film which is simple in structure, convenient for improving the anti-seismic and buffering effects, reducing the risk of breaking the anti-cracking toughened film, improving the structural strength and prolonging the service life of the anti-cracking toughened film.

The technical scheme of the invention is as follows: the utility model provides an anti-cracking tempering membrane, leaves the type rete including tempering layer, PET optical layer, glue film and PE, the tempering layer is flute structure, and the lower surface on tempering layer is located to the PET optical layer, and the PET optical layer passes through the glue film and leaves the type rete with PE and be connected.

Further, the tempering layer includes upper strata, middle flute layer and lower floor, upper strata and lower floor are the tempering layer, and the middle level is the corrugated layer of PET making.

Further, the upper layer, the middle corrugated layer and the lower layer are integrally arranged, and colorless and transparent repair liquid is arranged in the corrugated layer.

Further, the thickness of the corrugated layer is 10-20 μm.

Further, the thickness of the tempering layer is 40-100 μm.

Further, the upper surface of the tempering layer is provided with an explosion-proof membrane.

Further, the PET optical layer comprises a first PET optical layer and a second PET optical layer, and a filter disc is arranged between the first PET optical layer and the second PET optical layer.

Further, the filter is a blue light filter, an ultraviolet light filter or an electromagnetic wave filter.

Furthermore, the filter disc is made of a metal nano high-reflection coating.

The invention has the following characteristics: this scheme is effectual has improved antidetonation, the buffering effect of tempering membrane, has reduced the cracked risk of tempering membrane, can play automatic prosthetic effect to its self simultaneously, improves the used repeatedly of tempering membrane this moment, and then is convenient for improve the protection effect to the cell-phone.

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.

fig. 2-is another schematic structural diagram of the toughened film of the invention.

Detailed Description

As shown in the attached drawings: the utility model provides an anti-cracking tempering membrane, leaves the rete including tempering layer, PET optical layer, glue film and PE, and the tempering layer is flute structure, and the lower surface on tempering layer is located to the PET optical layer, and the PET optical layer passes through the glue film and leaves the type rete with PE and be connected. Preferably, the tempering layer includes upper strata, middle flute layer and lower floor, and upper strata, middle flute layer and lower floor are toughened glass and make, and upper strata, middle flute layer and lower floor are integrative to be set up, are equipped with colorless transparent repair liquid in the flute layer.

The anti-seismic buffer capacity that can effectual improvement tempering layer of this scheme, the setting on flute layer has promoted the antidetonation effect greatly, and the effectual risk of breaking that reduces the tempering layer can play automatic prosthetic effect to the tempering layer after breaking, has improved the used repeatedly number of times of tempering membrane, and then has improved life, reduces use cost simultaneously.

In another embodiment, the rigidized layer comprises an upper layer, a middle corrugated layer, and a lower layer, both of which are rigidized layers, with the middle layer being a corrugated layer made of PET. The buffering effect on promotion flute layer that can further be further, the cracked risk of reduction tempering upper strata and lower floor that can further, and then promote the antidetonation buffering effect on tempering, prevent the breakage. Preferably, the upper layer, the middle corrugated layer and the lower layer are integrally arranged, and the colorless and transparent repair liquid is arranged in the corrugated layer.

In an embodiment, the thickness of the corrugated layer is 10-20 μm; preferably, the thickness of the corrugated layer is 11-18 μm; preferably, the thickness of the corrugated layer is 12, 14, 15 or 16 μm, so that the buffering effect of the corrugated layer is improved, and the shock resistance is ensured.

In an embodiment, the thickness of the tempered layer is 40-100 μm; preferably, the thickness of the toughened layer is 45-90 μm; more preferably, the thickness of the toughened layer is 50, 60, 70 or 85 μm; and then promote the setting of middle flute layer, be convenient for its structural strength's promotion avoids thickness undersize to influence its structural strength simultaneously.

Preferably, the upper surface of the tempering layer is provided with an explosion-proof membrane. The tempering film breaking process is prevented from dropping, meanwhile, the repair liquid can be prevented from overflowing in the straight-going repair process through the repair liquid after breaking, the repair effect is convenient to promote, the surface of the tempering film is effectively protected, and meanwhile, the scratch is avoided.
