Abstract

The invention discloses an efficient antistatic process film for attachment of an OLED module and a production method of the efficient antistatic process film. The process film consists of an anti-adsorption conductive layer, a base material, an efficient conductive layer, a pressure-sensitive adhesive layer and a release film, one side of the base material is coated with the anti-adsorption conductive layer, the other side, which is a corona surface, is coated with the efficient conductive layer, and then the base material is attached to the release film through the pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer is a UV light viscosity-reduction adhesive layer and has antistatic performance. The back surface of the release film is coated with the anti-adsorption conductive layer. According to the process film of the invention, the anti-static requirements of a film surface and the back surface of the release film are increased on the basis of the anti-static property of the adhesive surface of the process film, so that electrostatic adsorption cannot be generated in the picking and using processes of the film, and the stability of the process is increased; meanwhile, the resistance of the adhesive surface is greatly reduced, the possibility of dust adsorption and electrostatic breakdown is low, the yield and the efficiency are improved, and the method is mainly applied to the attachment process of an OLED screen module at present.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a preparation method and a product thereof for a high-efficiency antistatic OLED module bonding process film. Background technique [0002] The high-efficiency anti-static OLED module bonding process film has super high adhesion, which can ensure that the OLED module remains stable, does not fall off, does not flash during processing, and protects the unprocessed part. After processing, as long as enough UV light is irradiated, its adhesive force can be reduced, so that the support body can be easily torn off, so that the OLED module can be used normally in the next production process. [0003] However, the traditional support protective film does not consider the anti-static requirements. During the tearing process, static electricity will cause dust adsorption or screen breakdown, which will have a negative impact on the OLED module. At the same time, the piles of films occasiona...
