Abstract
The utility model discloses a kind of PU protective membrane, and this PU protective membrane is made up of the first Polythiophene type antistatic backing, PET base material layer, PU pressure-sensitive adhesive layer and PET release film layer successively; Improve as one, between PET base material layer and PU pressure-sensitive adhesive layer, be also provided with the second Polythiophene type antistatic backing.The thickness of the first Polythiophene type antistatic backing and the second Polythiophene type antistatic backing is 0.02 μm ~ 2 μm; PU pressure-sensitive adhesive layer thickness is 2 μm ~ 30 μm; PET base material layer thickness is 25 μm ~ 250 μm, and transmittance is greater than 85%, and mist degree is less than 6%; PET release film layer thickness is 25 μm ~ 150 μm.PU protective membrane of the present utility model uses under the high temperature conditions can anti-electrostatic effectively, little by humidity effect, avoids white mist problem to occur under hot and humid condition.
Description
Technical field
The utility model relates to a kind of PU protective membrane, belongs to electrical fittings technical field.
Background technology
In recent years; the fast development of electronic product has driven the fast development of touch-screen industry; also the development of the ito thin film relevant to touch-screen has been driven; also the development to the relevant protective membrane of ito thin film has been driven thus; in the high-temperature shrinkage strengthening of ito thin film; the wherein one side of ito thin film can attach PU protective membrane to guarantee not scratched by foreign object or destroy, so it is significant to develop a kind of PU protective membrane producing white mist problem because of anti-static liquid water suction of avoiding.As patent CN203210793U discloses a kind of Antistatic protective film; antistatic cementing layer is silica gel material; but in high-temperature process; silicon molecule in silicon layer can transfer to ito thin film surface; form similar silicon molecular contamination vaporific in vain; this just have impact on the optical property of ito thin film, causes the reduction of yield.At present, in prior art, the antistatic coating of PU protective membrane commonly uses vinylformic acid and modified acroleic acid family macromolecule cooks antistatic agent, but the wetting ability of this type of static inhibitor easily makes PU protective membrane produce white mist problem.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of PU protective membrane not being subject to humidity effect, avoiding white mist problem to occur.
For solving above technical problem, the utility model is realized by following technical scheme.
A kind of PU protective membrane, comprises the first Polythiophene type antistatic backing, PET base material layer, PU pressure-sensitive adhesive layer and PET release film layer successively.
Preferably, the thickness of described first Polythiophene type antistatic backing is 0.02 μm ~ 2 μm.
Preferably, the thickness of described PU pressure-sensitive adhesive layer is 2 μm ~ 30 μm.
Preferably, the thickness of described PET base material layer is 25 μm ~ 250 μm, and transmittance is greater than 85%, and mist degree is less than 6%.
Preferably, the thickness of described PET release film layer is 25 μm ~ 150 μm.
The beneficial effects of the utility model are, adopt Polythiophene type polymer anti-static liquid coating, reasonable design coat-thickness, PU protective membrane uses the effect can playing anti-electrostatic under the high temperature conditions, little by humidity effect, not easily produces white mist problem.
Improve as one of the present utility model, the second Polythiophene type antistatic backing is set between described PET base material layer and PU pressure-sensitive adhesive layer, the effect of two-sided anti-electrostatic can be reached, improve the antistatic performance of this PU protective membrane.
Preferably, the thickness of described second Polythiophene type antistatic backing is 0.02 μm ~ 2 μm.
