Description
Technical field
The utility model is related to a kind of PET protection film more particularly to a kind of low dyestripping voltage antistatic PET protection films, belong to
In protective film of electronic product field.
Background technology
Transparent anti static PET protection film has been widely used for touch panel (TP, the Touch of touch screen factory now
Panel processing procedure) and shipment protection.
Currently, global touch screen market development is getting faster, and industry size is in rapid growth.In smart mobile phone, tablet electricity
The multi-field applications such as brain, stylus electricity, wearable device, onboard system, information management system can deepen continuously.It touches simultaneously
Screen technology also develops to directions such as multiple point touching, enlargement and thin lightweights, the antistatic work(of this auxiliary material being also used for
Requirements at the higher level, the protective film that especially TP shipment uses can be proposed, it is desirable that it there must be excellent anti-static function, avoid
It is final remove caused charge breakdown TP when protective film and caused by lose.
Traditional antistatic PET protection film, is that polyurethane contact adhesive is coated in PET base material, and then laminating PET is release
Film.In order to avoid touch screen producer it is final remove protective film carry out it is lower examine together or when assembling procedure, because protective film is torn
Glue-line usually is designed to have certain by the functional assemblies such as the electronic component in electrostatic breakdown or damage TP except generation
The anti-protective film of the pressure sensitive adhesive of anti-static function, i.e. glue.Also there is portioned product in view of right caused by electrostatic in actual use simultaneously
The adverse effect of actual job also has and does the dual anti-protective film that film forming is anti-and glue is anti-in PET base material surface coating antistatic backing
Scheme.
But, with the development of touch screen technology, more and more touch screen factory feedbacks, even with dual anti-protection
Film also will produce a certain proportion of bad functional test that can interfere with TP and lead to occur NG's when operation is examined at the scene
Phenomenon.Its disadvantage is that electrostatic when can not avoid removing release film generates, when carrying out dyestripping voltage tester, in room temperature condition, A4
Size dimension, dyestripping voltage are more than 1kV.Its main cause is as follows, and process for using of the protective film for TP shipment protection is：First
Corresponding protective film is die-cut to suitable size, the guarantor that then field operation person will be die cut according to the gauge size of touch screen
Release film in protection film structure removes (process will produce very big electrostatic), and will be fitted to glue-line needs TP panel areas to be protected
Domain, then quality restriction personnel can to TP carry out functional test, pack shipment after the assay was approved.Therefore, traditional antistatic
PET protection film, the electrostatic generated when removing release film when can not solve field operation doing plastic and resisting.
