Description
Technical field
The utility model relates to protect technical field of membrane, and in particular, to a kind of tempering thermoplastic curved surface film.
Background technique
Mobile phone is one of most common electronic product in daily life, and to prevent screen from being scratched or being broken into pieces, people are universal
One layer of mobile phone toughened protective film can be sticked on mobile phone screen surface.
With the development of science and technology camber display screen is a dark horse.It is one that camber display screen, which is different from conventional mobile phone screen,
The feature of plane has certain radian.Compared with flat-faced screen, camber display screen has better sensory experience, higher
Screen display resolution, lower screen thickness, thus receive pursuing for people.Such as Samsung Galaxy S8, millet
Note 2, vivi v9 etc. is the mobile phone with full view hyperbolic face.In mobile phone toughened protective film structure in the prior art
Primary structure is tempered glass, since tempered glass intensity is high, can with flat-faced screen is good is bonded, there is fabulous guarantor
Shield effect.However, cannot be matched well with the toughened protective film that tempered glass produces with camber display screen, can go out in fitting
Phenomena such as existing gap, is easy to appear alice, bubble, shape is unsightly.For this purpose, manufacturer increases often through in tempering cuticula
Add the thickness of OCA glue, attempt blind, eliminates bubble, prevent alice.The thickness of OCA glue in common mobile phone toughened protective film
Degree reaches 175um or more.However, on the one hand OCA glue thickness, which reaches 175um, increases peeling force；On the other hand, due to OCA glue
It is expensive, also increase the cost of mobile phone toughened protective film.
It solves to exist in the prior art to adapt to the needs of camber display screen it would therefore be highly desirable to research and develop tempering thermoplastic curved surface film
The problem of.
Utility model content
For this purpose, the utility model provides a kind of tempering thermoplastic curved surface film, the tempering thermoplastic curved surface film polycarbonate membrane
(Polycarbonate, PC film) or polycarbonate (PC) and polymethyl methacrylate (PMMA) composite material replace tempering
Glass, manufactured tempering thermoplastic curved surface film can be sufficiently bonded with camber display screen, avoid the production of alice, gap and bubble
It is raw, the dosage of OCA glue is also greatly reduced, production cost has been saved, there is great economic significance, is suitable for display screen,
The fields such as vehicle glass.
The technical solution of the utility model is as follows: a kind of tempering thermoplastic curved surface film, including PC layers；The PC layers of one side applies
