Abstract

The invention discloses a protection film capable of being attached to a cambered-surface edge and a preparation method of the protection film. The protection film is of a laminar structure, and comprises a first PET release film layer, a self-repairing coating, a TPU layer, an OCA layer, a PET layer, a silica gel layer and a second PET release film layer which are sequentially laminated. The protection film has the advantages that the self-repairing layer has good adhesive force; the formation size is accurate; the repairing speed is high; the cambered-surface edge is stable; rebounding is avoided, and the like.

Description

technical field [0001] The invention relates to the field of protective films for electronic products, in particular to a protective film that can fit the edge of an arc surface and a preparation method thereof. Background technique [0002] 2.5D curved surface mobile phones and 3D curved surface mobile phones are becoming more and more popular. From the flagship phones released from 2015 to 2016, it can be seen that the market share of curved surface mobile phones is close to 90%. And judging from the increasing data and some information, Curved mobile phones are a major development trend, and the market share will continue to increase. [0003] In order to cope with curved mobile phones, mobile phone protective films have also successively developed TPU+acrylic film, hot-bent PET film, and hot-bent tempered glass film; but even so, there is no product that can perfectly solve the problem of sticking curved mobile phones; such as (1 ) TPU + acrylic adhesive film: TPU mater...
