Description

Explosion-proof writing film

Technical Field

The utility model relates to an explosion-proof writing film.

Background

The membrane of writing of prior art is common has two kinds, the first kind is by 0.2 mm's dull polish PC layer, 0.13mmAB glue film, half disconnected type rete, take the gluing from the type strip, 1/2/3 tear the mark glue and synthesize, the second kind is by 0.2mm dull polish PC layer, the double-sided glue film, magnet strip about the manual subsides in the back is prevented static PU strip and is synthesized, following defect that prior art exists, the first kind writes that the membrane production process is loaded down with trivial details, tear 1 mark location, 2 marks tear from the type membrane examination subsides, then bend the screen and accomplish. The second writing film sticking film has magnets on the left and right sides, needs manual operation for four times in the production process and is easy to fall off after die cutting is finished. The labor cost is increased in the production process.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a writing film which is simple in structure, simple in film pasting operation and has an explosion-proof function.

The technical scheme adopted by the utility model is as follows: the utility model provides an explosion-proof membrane of writing, its characterized in that, it includes the AB glue film, glass layer and dull polish PC layer, wherein, this AB glue film has upper surface and lower surface, this glass layer has last glass face and lower glass face, this dull polish PC layer has top surface and bottom surface, the upper surface at this AB glue film is laminated to the lower glass face on this glass layer, the last glass face at this glass layer is laminated to the bottom surface on this dull polish PC layer, the thickness on this AB glue film is 0.1mm-0.25mm, the thickness on this glass layer is 0.15 mm-0.3 mm, the thickness on this dull polish PC layer is 0.1mm-0.2 mm.

The lower surface of the AB glue layer is provided with a release film.

The bottom surface of the frosted PC layer is attached to the upper glass surface of the glass layer through a double-faced adhesive layer.

The utility model has the beneficial effects that: when the glass layer is used specifically, the release film is torn off to aim at the position of the tablet personal computer, the lower surface of the AB glue layer is attached to the surface of the tablet personal computer, the AB glue layer automatically exhausts air, so that a consumer can better, more simply and more conveniently complete the whole film attaching process, the dull polish PC layer disclosed by the utility model can better protect the tablet personal computer and prevent the tablet personal computer from slipping off, and the glass layer disclosed by the utility model can protect the display screen of the tablet personal computer, so that the effects of being not easy to break and preventing explosion are realized.
