Description
Technical field
The utility model is related to thin film technique field, more particularly to a kind of silica gel protected film.
Background technology
Silica gel protected film is mainly used in the screen surface of electronic product, used as the screen protecting film of electronic product.Tradition
Silica gel protected film includes upper substrate layer, lower substrate layer and the adhesive layer positioned at upper substrate layer and lower base material interlayer.Diaphragm
A large amount of electrostatic charges are peeled off and accumulate during fitting, the accumulation of a large amount of electrostatic charges can be produced during the use of diaphragm to electronics
Product produce fatefulue destruction risk, and the generation of a large amount of electrostatic charges can also adsorb dust particle, cause electronic product production process
In it is bad, and fitting with electronic product aeration of easily produce of diaphragm is attractive in appearance.
Chinese utility model patent specification CN 204820501U (day for announcing 2015.12.02) discloses a kind of " anti-quiet
The silica gel protected film of electricity ", including PET sheet layer, release layer, the side of the PET sheet layer arranges antistatic backing, and opposite side is arranged
Layer of silica gel, the release layer is arranged on layer of silica gel outside.The surface impedance of the silica gel protected film antistatic backing is 104-11Ω, tool
There is outstanding antistatic property, but with the prolongation of use time, antistatic backing is subject to a certain degree of abrasion, static electricity resistance
Can also decrease.
Utility model content
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of silica gel protected film.
To achieve these goals, the utility model is adopted the following technical scheme that：A kind of silica gel protected film, including upper base material
