Detailed Description

Referring to fig. 1, a specific structure of a preferred embodiment of the present invention is shown, which includes an acrylic layer 10, an EPU layer 20, an antibacterial layer 30, a silicone layer 40, an upper release layer 50, an adhesive layer 60, and a lower release layer 70.

In the present embodiment, the acrylic using layer 10 is made of soft and transparent acrylic, and the thickness of the acrylic using layer 10 is 120-200 μm.

The EPU layer 20 is attached on the surface of the acrylic using layer 10 by hot pressing, in this embodiment, the EPU layer 20 is made of polyurethane foam, the EPU layer 20 is in a soft transparent state, and the thickness of the EPU layer 20 is 50-125 μm.

This antibiotic layer 30 coats on the surface of EPU layer 20, in this embodiment, this antibiotic layer 30 is the film that contains nanometer zinc oxide powder, and thickness is 20 μm, when the user uses the cell-phone, the bacterium on the finger often can be attached to on the screen of cell-phone, we can often go to wash one's hand, but go to wash the cell-phone rarely, so the cell-phone has a lot of bacteria of accumulation, this antibiotic layer 30 can play antibiotic sterilization and the effect of inhibiting the bacterial growth, the bacterial load on the reduction cell-phone that can be great, prevent that the bacterium from attaching to user's hand from the cell-phone, the effectual human protection is not infringed by the bacterium, improve human health.
