Description

A kind of preparation method and products thereof that can tear off anti-absorbent-type screen process film at a high speed
Technical field
The present invention relates to adhesive tape areas, are specifically related to a kind of preparation that can tear off anti-absorbent-type screen process film at a high speed Method and products thereof.
Background technique
Electronic apparatus class product is highly prone to contact staining or production in its surface during carrying perhaps production and application Raw polishing scratch scratches, and protective film need to be used to carry out covering to make it from getting dirty or being damaged to its surface.This electron-like or electric type Protective film used in product must also have a characteristic, it may be assumed that it not can produce larger electrostatic when removing, in order to avoid to electronic apparatus class product It causes to damage；With becoming larger for screen size, the raising of production efficiency is required to be promoted, to the static dissipation capability of protective film It asks in the case where large scale and high speed are torn off, high electrical breakdown capacitor or sucking dust cannot be generated.And it is used for the protection of screen protection For film other than requirements above, also requiring the protective film is optical grade, and clean surface is visually observed with screen as if one.
Current antistatic protection film can only generally guarantee the screen protection of low speed or small size, in large scale screen or height In the case of speed is torn off, electrostatic dissipation speed is too slow, be easy to cause accumulation of static electricity, generates the high voltage of 2-5KV, in this case Easily puncture capacitor, causes screen damage, reduce yield rate or production efficiency, be unable to satisfy large-scale industrial production.
And can largely be stacked after being cut due to protective film, it is easily made because of the reason of Electrostatic Absorption during taking piece It is not readily separated together at several films of contact are glutinous, causes to take piece difficult, influence production efficiency and stability.
