Adsorption preventive type screen process film capable of being peeled at high speed and method for preparing adsorption preventive type screen process film

Abstract

The invention discloses an adsorption preventive type screen process film capable of being peeled at the high speed and a method for producing the adsorption preventive type screen process film. The adsorption preventive type screen process film comprises a base material, an efficient conductive layer, a pressure-sensitive adhesive layer, a release film and adsorption preventive conductive layers.The efficient conductive layer is coated on one surface of the base material and then is laminated with the release film by the pressure-sensitive adhesive layer, and the adsorption preventive conductive layers are coated on the other surface of the base material and the back surface of the release film. The adsorption preventive type screen process film and the method have the advantages that the antistatic ability of adhesive surfaces can be greatly improved by the adsorption preventive type screen process film, accordingly, the requirements can be met by the static electricity dissipationspeeds of the adhesive surfaces in screen slice fetching processes with the peeling speeds reaching 10 cm / s, dust suction or screen breakdown due to accumulation of a large quantity of static electricity can be prevented, the production efficiency can be improved, and the yield can be increased; the adsorption preventive type screen process film comprises the adsorption preventive conductive layers, accordingly, electrostatic adsorption conditions can be prevented in the slice fetching processes, and the stability of technological processes can be improved.

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-speed tear-off anti-adsorption type screen process film. Background technique [0002] During the handling or production and use of electronic and electrical products, the surface is extremely susceptible to contact pollution or scratches. It is necessary to use a protective film to cover the surface to prevent it from being polluted or damaged. The protective film used for such electronic or electrical products must also have a characteristic, that is, it must not generate large static electricity when it is removed, so as not to cause damage to electronic and electrical products; with the increase of screen size and the improvement of production efficiency, the The electrostatic dissipation capability of the protective film is required to be improved, and it is required that high voltage breakdown capacitors or dust inhalation ...

AI Technical Summary

Problems solved by technology

[0003] The current anti-static protective film generally can only guarantee the protection of low-speed or small-sized screens. In the case of large-sized screens or high-speed tearing off, the static electricity dissipation speed is too slow, which is easy to cause static electricity to accumulate and generate high voltages of 2-5KV. In this case, it is very easy to break down the capacitor, causing damage to the screen, reducing the yield or production efficiency, and unable to meet large-scale industrial production.

[0004] Moreover, since the protective film will be stacked in large quantities after slitting, it is very easy to cause several contacted films to stick together due to electrostatic adsorption during the film taking process, making it difficult to separate, making it difficult to take the film, affecting production efficiency and stability
