The attached drawings indicate the following:
10. acrylic use layer 20 and EPU layer
30. Acrylic acid glue layer 40 and silica gel layer
50. Upper release layer 60 and lower acrylic glue layer
70. And a lower release layer.
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 upper acrylic glue layer 30, a silica gel layer 40, an upper release layer 50, a lower acrylic glue 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.
The upper acrylic glue layer 30 is coated on the surface of EPU layer 20. in this embodiment, the thickness of the upper acrylic glue layer 30 is 4-5 μm, and the upper acrylic glue layer 30 mainly functions as an adhesive.
The silica gel layer 40 is coated on the surface of the acrylic acid glue layer 30, in the embodiment, the silica gel layer 40 is made of transparent silica gel, the thickness of the silica gel layer 40 is 10-14 μm, the silica gel layer 40 has strong reducibility, and can be quickly restored to the original shape without damaging the original shape even through bending and folding for many times, and the folding strength in the folding mobile phone can be well adapted. The acrylic glue layer 30 has strong viscosity, and can bond the EPU layer 20 and the silica gel layer 40 together, thereby improving the bonding force of the product.
The upper release layer 50 is attached on the surface of the silicone layer 40, in this embodiment, the upper release layer 50 is a transparent fluorine release film, and the thickness of the upper release layer 50 is 25-29 μm. This go up from the silica gel layer 40 that the protection setting that type layer 50 can be fine was last from the type layer 50 below, prevent that silica gel layer 40 from causing the damage to it in the transportation.
The lower acrylic glue layer 60 is coated on the bottom surface of the acryl use layer 10, and in this embodiment, the lower acrylic glue layer 60 has a thickness of 4 to 5 d, and the lower acrylic glue layer 60 mainly plays a role of adhesion.
