Abstract
The utility model discloses a PET (Polyethylene Terephthalate) protective film used in the manufacturing process of a flat-panel display, which is characterized in that the PET protective film comprises an optical-grade PET protective film substrate and pressure-sensitive adhesive with low polarity, wherein the pressure-sensitive adhesive with low polarity is coated on the upper surface of the optical-grade PET protective film substrate. Through using the pressure-sensitive adhesive with low polarity and the optical-grade PET protective film substrate, as the pressure-sensitive adhesive has low polarity and large cohesion force, is inert and has the instantaneous pasting and covering performance for the glass material surface of the flat-panel display, the protective film manufactured by the utilization of the pressure-sensitive adhesive, the optical-grade PET protective film substrate and the like has the characteristics that the protective film does not fall off, is easy to strip after evaporated, is free from residual adhesive, is not polluted and is high-temperature resistant and antistatic and can effectively prevent glass lenses from being damaged in the stripping process.
Description
Technical field
The utility model relates to a kind of PET protective membrane, relates to a kind of flat-panel monitor processing procedure PET protective membrane specifically, belongs to chemoproection membrane technique field.
Background technology
Flat panel display is the basic technology of information-based industry, it also is emerging technology in the ascendant in recent years, one of flat-panel monitor two big main structures are the glass substrate of material with the unorganic glass exactly, function needs such as flat-panel monitor is thin, light, little in order to adapt to, high transmission rate, the thickness of glass substrate thins down, the thinnest glass substrate only has 0.4mm thick at present, this kind glass substrate is to become the pieces of glass eyeglass of different shape size to be made large-sized glass cutting, polishes smooth around it then.In addition; in order to eliminate the refraction of light of glass substrate; increase its transmittance; need be with glass mirror local location evaporation one deck super thin metal; and in order in evaporate process, to prevent to damage the shielding of scratch glass mirror and non-evaporated segment, so need with a kind of acid and alkali-resistance, anti-180 ℃ of high temperature, antistatic, easy attaching, easily peel off, free of contamination protective membrane.
What the traditional protection film used is common PP protective membrane base material, and its surface coated be common adhesive-layer, this kind protective membrane has many deficiencies: the one, deflection is not enough, the incompatibility mechanical manipulator is inhaled fast and is put applying; The 2nd, not antistatic, influence quick suction of mechanical manipulator and put; The 3rd, undercapacity is in the thick glass high speed rotating when polishing of protection 0.4mm; Therefore four are to use the clinging power of common pressure sensitive adhesive very high, and unusual difficulty when glass mirror is torn is damaged glass mirror sometimes even therefore; The 5th, not anti-180 ℃ of high temperature.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of polarity is low, antistatic, intensity is big and resistant to elevated temperatures flat-panel monitor processing procedure PET protective membrane.
For solving the problems of the technologies described above, the technical scheme that the utility model is used is:
A kind of flat-panel monitor processing procedure PET protective membrane; it is characterized in that; it comprises the PET protective membrane base material and the low pressure sensitive adhesive and the release film of polarity of optical grade; wherein; the pressure sensitive adhesive that polarity is low is coated the one side of the PET protective membrane base material of optical grade, and release film then is laminated to the upper surface of the low pressure sensitive adhesive of polarity.
Described flat-panel monitor processing procedure PET protective membrane is characterized in that, the low pressure sensitive adhesive of described polarity is with 18～20 gram/m
2Grammes per square metre and 18～19 μ m dry layer thickness one side that is coated on the PET protective membrane base material of described optical grade.
Described flat-panel monitor processing procedure PET protective membrane is characterized in that, the thickness of the PET protective membrane base material of described optical grade is 50～150 μ m.
Described flat-panel monitor processing procedure PET protective membrane is characterized in that, polyester films such as the PET protective membrane base material selection of described optical grade is transparent, blue, black, white.
Described flat-panel monitor processing procedure PET protective membrane is characterized in that described release film is selected from any in polyethylene film, polypropylene film, polyester film, the natural paper.
Described flat-panel monitor processing procedure PET protective membrane is characterized in that, the low pressure sensitive adhesive of described polarity is 2～5gf/25mm 180 ° peeling force.
The beneficial effects of the utility model are: the utility model is by using the low pressure sensitive adhesive of polarity and the PET protective membrane base material of optical grade; polarity is low because pressure sensitive adhesive has, force of cohesion is big, show inertia; and the flat panel display glass material surface had pasting property of moment; therefore utilize the protective membrane of the preparations such as PET protective membrane base material of pressure sensitive adhesive and optical grade to have not come off, easily peel off behind the evaporation, not cull, do not pollute, high temperature resistant, anlistatig characteristic, can prevent effectively that it from damaging glass mirror in the process of peeling off.
