The hardened film is realized in a roller coating mode, through UV-A wave band ultraviolet curing, the integral thickness of the first hardened film and the second hardened film reaches 3-4um, the wear-resisting times reach more than 1000 cycles, and the hardened film can be widely applied to mobile phone screen protective films.
Description
Technical Field
The utility model relates to a protection film field especially relates to novel sclerosis membrane.
Background
The performance of the currently available hardened film is single, and the common hardened film is limited by the difficulty in realizing the functions of antifogging, antistatic and high wear resistance by integrating the functions of HC coating.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model adopts the following technical scheme: the utility model provides a novel hardening membrane, includes the substrate layer, the substrate layer one side coating has pressure sensitive adhesive layer, and the another side is provided with first sclerosis layer, antistatic coating and second sclerosis layer, first sclerosis layer surface is formed with the recess, the embedding of antistatic coating in the recess, second sclerosis layer and first sclerosis layer lock form enclosed construction.
Further, first sclerosis layer and second sclerosis layer are all through ultraviolet curing's acrylic resin constitution.
Further, the substrate layer is a PET film.
Further, the first hardening layer is solidified on the corona surface of the base material layer.
Furthermore, a release film is attached to the surface of the pressure-sensitive adhesive layer.
Further, the integral thickness of the first hardened film and the second hardened film is 3-4 um.
The utility model discloses a theory of operation does: the special ultraviolet light is adopted to cure the acrylic resin, wherein the acrylic resin contains hydrophilic groups, has good hydrophilic performance and can realize an antifogging function; through the structure that divide into first sclerosis layer, the mutual lock in second sclerosis layer with the sclerosis layer, solidify the ionic antistatic agent for the coating presss from both sides between two sclerosis layers, can realize antistatic function, this hardening film still possesses very strong antifriction performance simultaneously.
The utility model has the advantages that: the hardened film is realized in a roller coating mode, through UV-A wave band ultraviolet curing, the integral thickness of the first hardened film and the second hardened film reaches 3-4um, the wear-resisting times reach more than 1000 cycles, and the hardened film can be widely applied to mobile phone screen protective films.
