Problems solved by technology

[0002] Nowadays, there are many mobile phones with curved screens. The film of the existing technology is made of hard film (glass film, acrylic film, pet film). The elastic phenomenon causes the mobile phone and the film body to not fit in place, and the film body has warping and peeling phenomena, and the flexible film of the prior art has the problem of leaving traces easily
Above-mentioned technical problem can't satisfy people's requirement, needs to be improved badly

Abstract

The invention discloses a pasting film and a pasting method thereof. The pasting film is of a composite layer structure and comprises a base material layer, a silica gel layer, a semi-solidified gluelayer, a polyethylene glycol terephthalate layer, a glue layer and a self-exhausting glue layer; the pasting method of the pasting film comprises the following steps that liquid semi-cured glue is prepared into semi-cured glue through a UV curing method or a temperature curing method or a moisture curing method, the glue layer and the self-exhausting glue layer are attached, pressing and exhausting are conducted, air between a film body and a screen is exhausted, the film body and the screen are tightly attached, secondary curing is carried out by adopting a UV curing method, a temperature curing method or a moisture curing method and the like. According to the pasting film and the pasting method, the 3D film and the screen can be tightly attached, tolerance is filled, the problem that thecurved screen and the 3D film are not tightly attached is solved, air is exhausted through exhaust glue, bubbles are avoided, a glue layer does not rebound or deform, full attachment is comprehensively achieved, and compared with a flexible film, the pasting film and the pasting method have the advantage that marks are not prone to being left.

Description

technical field [0001] The invention relates to a sticking film and a sticking method thereof, and belongs to the technical field of films, sheets and adhesives on carriers. Background technique [0002] Nowadays, there are many mobile phones with curved screens. The film of the existing technology is made of hard film (glass film, acrylic film, pet film). The elastic phenomenon causes the mobile phone and the film body to not fit in place, and the film body has warping and peeling phenomena, and the flexible film of the prior art has the problem of leaving traces easily. Above-mentioned technical problem can't satisfy people's requirement, needs to be improved badly. Contents of the invention [0003] The object of the present invention is to provide a sticking film and a sticking method thereof, so as to solve the shortcomings of the prior art. [0004] The present invention adopts following technical scheme to realize: [0005] A film, comprising a base material laye...
