Be applicable to the high temperature resistant protective membrane of non-ITO conducting film; comprise and being cascading: substrate layer, high-temperature Resistance Adhesives layer, release film layer; described high-temperature Resistance Adhesives layer is made by acrylic acid or the like sizing agent; the thickness of described substrate layer is 0.038-0.188mm; under the condition of 180 ℃/60min; longitudinal percent thermal shrinkage of protective membrane is 0.75-1.0%, and laterally percent thermal shrinkage is 0.40-0.65%.
Preferably, aforementioned substrates layer is made by PET film.
Preferably, aforementioned release film layer is made by the PET material with silicon coating.
Preferably, the thickness of aforementioned substrates layer is 0.05-0.12mm.
Preferably, under the condition of 180 ℃/60min, longitudinal percent thermal shrinkage of protective membrane is 0.85-1.0%, and laterally percent thermal shrinkage is 0.5-0.65%.
Preferably, aforementioned high-temperature Resistance Adhesives layer is made by acrylic acid or the like sizing agent, is wherein also added with the isocyanic ester of 5-8wt%.
Usefulness of the present utility model is: high temperature resistant protective membrane of the present utility model, can protect the full processing procedure of non-ITO conducting film, and guarantee quality product, improve product yield, and preparation process is simple and easy to realize; The high temperature resistant protective membrane adopting in the utility model under the condition of 180 ℃/60min without cull, without particle, can not impact the surface quality of product, and protective membrane of the prior art cannot withstand high temperatures, can produce a large amount of culls and particle under the condition of 100 ℃/60min; And; the pyroprocess that also solved high temperature resistant protective membrane of the present utility model well causes the problem of non-ITO conducting film warpage and distortion; by specific base material, coordinate with specific sizing agent; the lateral shrinkage and the longitudinal contraction rate that have realized protective membrane are all suitable with non-ITO conducting film; be that the shrinking percentage of protective membrane and the shrinking percentage of product (non-ITO conducting film) keep mating; the angularity of the finished product is less than 3mm; and adopt protective membrane of the prior art; under equal conditions, angularity is generally all more than 20mm.
Accompanying drawing explanation
Fig. 1 is the structural representation of a specific embodiment of the high temperature resistant protective membrane that is applicable to non-ITO conducting film of the present utility model.
The implication of Reference numeral in figure: 1, substrate layer, 2, high-temperature Resistance Adhesives layer, 3, release film layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1, the high temperature resistant protective membrane that is applicable to non-ITO conducting film of the present utility model, comprises being cascading: substrate layer 1, high-temperature Resistance Adhesives layer 2, release film layer 3.Wherein, substrate layer 1 is preferably by PET(polyethylene terephthalate) film makes, and thickness is 0.038-0.188mm, more preferably 0.05-0.12mm; High-temperature Resistance Adhesives layer 2 is made by acrylic acid or the like sizing agent, preferably wherein also be added with the isocyanic ester of 5-8wt%, further to optimize the performance of sizing agent, practice confirms, this is high temperature resistant protective membrane without cull, without particle, can not impact the surface quality of product after the high bake of 180 ℃/60min of experience; Release film layer 3 is made by the PET material with silicon coating, separated with adhesive layer to facilitate.The high temperature resistant protective membrane of this structure, under the condition of 180 ℃/60min, longitudinal percent thermal shrinkage of protective membrane is 0.75-1.0%, laterally percent thermal shrinkage is 0.40-0.65%, the control of shrinking percentage realizes in conjunction with specific base material by the specific high-temperature Resistance Adhesives of the utility model, and in general, longitudinal percent thermal shrinkage of the non-ITO conducting film on market is 0.75-1.0%, laterally percent thermal shrinkage is 0.45-0.65%, so, just make the shrinking percentage of protective membrane of the present utility model and the shrinking percentage of product keep mating, thereby play the effect that effectively prevents warpage.
