Multi-layer texture dazzling mobile phone rear cover

Technical Field

The utility model relates to a lid behind the cell-phone especially relates to a various lid behind cell-phone is dazzled to multi-level texture.

Background

The mobile phone rear cover is an accessory arranged on the back of the mobile phone and mainly plays a role in protection and decoration. In order to realize the texture effect, some mobile phone rear covers are provided with texture layers. When a multi-texture composite effect is required, a plurality of texture layers can be arranged on the rear cover of the mobile phone.

However, the multilayer texture layers of the rear cover of the current mobile phone are all arranged on the same surface, so that the layering sense is poor. In addition, because the texture layer is mostly formed by using the UV glue, the hardness of the UV glue after being cured is higher, and the hardness of the UV glue after being cured is increased by simply overlapping the UV glue with multiple layers of cured layers, but the position is also fragile, and cracks are easy to generate during bending.

SUMMERY OF THE UTILITY MODEL

The utility model discloses technical scheme is to above-mentioned condition, and cover behind the various cell-phone is dazzled to multi-level texture is provided in order to solve above-mentioned problem, the cell-phone back cover includes: first UV texture layer, substrate layer, mirror surface silver-colored ink layer, second UV texture layer, first brightening rete, explosion-proof rete, third UV texture layer, second brightening rete and cover end ink layer, first UV texture layer, substrate layer, mirror surface silver-colored ink layer, second UV texture layer, first brightening rete, explosion-proof rete, third UV texture layer, second brightening rete and cover end ink layer are range upon range of in proper order.

Further, the substrate layer is a composite plate prepared by co-extruding PMMA and PC.

Further, the thickness of the first UV texture layer is 15 to 20 micrometers; the thickness of the second UV texture layer is 15 to 20 micrometers; the thickness of the third UV texture layer is 15-20 mu m.

Further, the thickness of the substrate layer is 500-800 μm.

Further, the thickness of the mirror surface silver ink layer is 4 to 6 micrometers.

Further, the thickness of the first brightening film layer is 0.15 to 0.25 mu m; the thickness of the second brightening film layer is 0.15-0.25 mu m.

Further, the thickness of the explosion-proof film layer is 70 to 80 μm.

Further, the thickness of the under-cover ink layer is 24 to 28 micrometers.

Further, the bottom covering ink layer is formed by sequentially laminating four single ink layers, and the thickness of each single ink layer is 5-7 μm.

After the technical scheme is adopted, the beneficial effects of the utility model are that:

1. because the utility model discloses form first UV texture layer and second UV texture layer respectively at the top surface and the bottom surface of substrate layer to form third UV texture layer in the bottom surface of explosion-proof rete, consequently can realize three-layer texture layer phase separation, form more three-dimensional, the texture effect that has the stereovision more.

2. Because the anti-explosion film layer is additionally arranged in the rear cover of the mobile phone, the anti-explosion effect of the inner layer can be achieved, and the possibility of cracks is reduced.

Detailed Description

The technical solution of the present invention is further described below by way of examples:

the utility model provides a lid behind various cell-phone is dazzled to multi-level texture, as shown in FIG. 1, the lid includes behind the cell-phone: first UV texture layer 1, substrate layer 2, mirror surface silver ink layer 3, second UV texture layer 4, first brightening rete 5, explosion-proof rete 6, third UV texture layer 7, second brightening rete 8 and cover end ink layer 9, first UV texture layer 1, substrate layer 2, mirror surface silver ink layer 3, second UV texture layer 4, first brightening rete 5, explosion-proof rete 6, third UV texture layer 7, second brightening rete 8 and cover end ink layer 9 stack gradually.

The substrate layer 2 is used as a substrate of the rear cover of the mobile phone; the first UV texture layer 1, the second UV texture layer 4 and the third UV texture layer 7 are all used for forming textures of a rear cover of the mobile phone; the mirror surface silver ink layer 3 can enable the base material layer 2 to have a mirror surface effect and is generally used for forming LOGO of manufacturers; the first brightening film layer 5 and the second brightening film layer 8 are used for enhancing the light reflection capability of the rear cover of the mobile phone, so that the brightness is improved; the explosion-proof film layer 6 is used for enhancing the bonding force and tensile force of the mobile phone rear cover; the cover bottom ink layer 9 is used for forming the bottom color of the mobile phone rear cover.

In the production of the first UV texture layer 1 and the second UV texture layer 4, UV glue is transferred to the top surface and the bottom surface of the base material layer 2, and the first UV texture layer 1 and the second UV texture layer 4 are formed by curing the UV glue by ultraviolet irradiation, but it is needless to say that the mirror silver ink layer 3 needs to be printed on the bottom surface of the base material layer 2 before the transfer is performed on the bottom surface of the base material layer 2. In the production of the third UV texture layer 7, a UV paste is transferred to the bottom surface of the explosion-proof film layer 6, and the UV paste is cured by ultraviolet irradiation to form the third UV texture layer 7. After the first brightening film layer 5 is formed on the top surface of the explosion-proof film layer 6 through a film coating process, the explosion-proof film layer 6 is attached to the bottom surface of the base material layer 2, and a three-layer texture structure can be formed.

Because the utility model discloses form first UV texture layer 1 and second UV texture layer 4 respectively at the top surface and the bottom surface of substrate layer 2 to form third UV texture layer 7 in the bottom surface of explosion-proof rete 6, consequently can realize three-layer texture layer phase separation, form more three-dimensional, the texture effect that has the stereovision more.

Because the anti-explosion film layer 6 is additionally arranged in the rear cover of the mobile phone, the anti-explosion effect of the inner layer can be achieved, and the possibility of cracks is reduced.

In addition, although UV texture layer is transparent material, the condition of decay still can appear through multilayer UV texture layer to light, because the lid is provided with two-layer blast rete behind the cell-phone, consequently can improve light reflectivity greatly to two-layer blast rete makes different UV texture layer present respectively and dazzles various effect.

Specifically, the substrate layer 2 is a composite plate prepared by co-extruding PMMA and PC. The composite board is an optical-grade board and has a transparent glass-imitating effect.

Specifically, the thickness of the first UV texture layer 1 is 15 to 20 μm.

Specifically, the thickness of the base material layer 2 is 500 to 800 μm.
