Abstract
The utility model discloses a high temperature resistant protective film used in a conducting glass preparation process. The protective film comprises a PET (polyethylene terephthalate) release film, a low viscose layer and an optical PET base material which are arranged from top to bottom in sequence. The protective film is characterized in that a cover layer is also arranged on the lower surface of the optical PET base material and is a resin coating with nanoparticles inlaid inside. The protective film has the advantages that the cover layer is arranged at the bottom layer, thus preventing atomization caused by precipitation of small molecules in the optical PET base material in a high temperature treatment process and effectively avoiding mistaken testing and misjudgement of the conducting glass preparation process caused by the problem of atomization; meanwhile, nanoparticle structures are inlaid inside the cover layer, thus effectively playing an anti-coupling role and being convenient for rolling.
Description
Technical field
the utility model relates to a kind of high temperature resistant protective membrane, the high temperature resistant protective membrane of especially a kind of conductive glass processing procedure.
Background technology
conductive glass is widely used in technical field of flat panel display, also be emerging technology in the ascendant in recent years, one of flat-panel monitor two large main structures are exactly the glass substrate taking unorganic glass as material, the 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 of glass substrate is to become the pieces of glass eyeglass of different shape size to be made large-sized glass cutting, then its surrounding polished smooth.In addition; in order to eliminate the refraction of light of glass substrate; increase its transmittance; need to be by glass mirror local location evaporation one deck super thin metal; and in order to prevent from damaging the shielding of scratch glass mirror and non-evaporated segment in evaporate process, therefore need be with a kind of acid and alkali-resistance, high temperature resistant, antistatic, easy attaching, easily peel off, free of contamination protective membrane.A kind of protective membrane is provided in prior art; mainly comprise PET protective membrane base material, pressure sensitive adhesive and release film that polarity is low; can effectively address the above problem; but in high temperature deposition process; because the small molecules in PET protective membrane base material is separated out and is easily caused atomizating phenomenon; thereby impact is made test and judgement to ITO conductive glass, and in wrapup procedure, is prone to coupling phenomenon.
Summary of the invention
the utility model object is: provide a kind of simple in structure, effectively prevent from that optics PET base material small molecular from separating out to cause atomizating phenomenon, and anti-coupling, be convenient to the high temperature resistant protective membrane of conductive glass processing procedure of rolling.
the technical solution of the utility model is: the high temperature resistant protective membrane of a kind of conductive glass processing procedure; comprise the PET release film setting gradually from top to bottom; low adhesive-layer and optics PET base material; it is characterized in that; also be provided with capping layer at described optics PET base material lower surface, described capping layer is the resin coating that inside is inlaid with nanoparticle.
preferably, described resin coating is vibrin coating, urethane resin coating or acrylic resin coating.
preferably, described resin-coated thickness is 20～1000nm, and the diameter of described nanoparticle is 5～50nm.
preferably, described PET release film is polyethylene film, polypropylene film, polyester film or natural paper, and its thickness is 20～50um, and one side is provided with silicone release layer.
