Abstract

The invention discloses a PET (polyethylene terephthalate) protective film for preparing a flat-panel display, which is characterized by comprising an optical-level PET protective film base material and low-polarity pressure-sensitive adhesive, wherein the low-polarity pressure-sensitive adhesive is coated on the upper surface of the optical-level PET protective film base material. Since the pressure-sensitive adhesive has the characteristics of low polarity and high cohesive force, is inert, and can be instantaneously attached to the surface of the glass material of the flat-panel display, the protective film prepared from the pressure-sensitive adhesive, optical-level PET protective film and the like has the characteristics of no shedding, easy stripping after coating by vaporization, no adhesive residue, no pollution, high temperature resistance and static resistance, and can effectively avoid damaging the glass lens in the stripping process.

Description

technical field

[0001] The invention relates to a PET protective film, in particular to a PET protective film for a flat panel display manufacturing process, and belongs to the technical field of chemical protective films. Background technique

[0002] Flat-panel display technology is the basic technology of the information industry, and it is also an emerging technology in the ascendant in recent years. One of the two main structures of flat-panel displays is the glass substrate made of inorganic glass. The thickness of the glass substrate is becoming thinner and thinner, and the thickness of the thinnest glass substrate is only 0.4mm. This kind of glass substrate is made by cutting large-sized glass into small glass lenses of various shapes and sizes. made and sanded smooth all around. In addition, in order to eliminate the light refraction of the glass substrate and increase its light transmittance, it is necessary to evaporate a layer of ultra-thin metal on the glass le...
