Embodiment 1

[0053] During concrete implementation preparation, select following technology for use,

[0054] A preparation process for a double-layer textured back shell, comprising the steps of:

[0055] One: Prepare the glare texture layer:

[0056] A1) Select the high-transparency glare texture to draw the glare texture on the substrate, and make it into a mask. The mask is made of soda glass, and one side of the soda glass contains a chrome layer. and the opaque area, the wide line spacing is generally 0.25um-0.5um;

[0057] A2) Use a lithography machine manufactured by the Chinese Academy of Sciences for ultraviolet exposure. There is a photoresist plate under the mask (the thickness of the photoresist plate determines the depth of the texture), and the ultraviolet rays shine on the photoresist plate through the light-transmitting area. , carry out non-contact exposure to the blank mask plate with photoresist plate (that is, non-contact exposure to the position of the mask plate in...

Abstract

The invention provides a preparation process of a double-layer texture back shell. The preparation process of the double-layer texture back shell comprises the following steps of: 1, preparing a dazzle light texture layer; 2, preparing a ramp texture layer; and 3, bonding the dazzle light texture layer and the ramp texture layer through light-transmitting glue, and bonding a light-transmitting plate to the upper part of the dazzle light texture layer. According to the preparation process of the double-layer texture back shell provided by the invention, the texture display of the back shell with the ramp effect and the bottom layer effect combined is adopted, and the texture display is added on the basis of the ramp effect, so that the ramp effect and the dazzle light texture form the combined display, and the display diversity is increased.

Description

technical field [0001] The invention relates to the technical field of a back case, in particular to a preparation process for an electronic device back case, in particular to a preparation process for a double-layer textured back case. Background technique [0002] With the development of electronic products, the appearance is getting lighter and thinner, and the surface treatment of electronic products is becoming more and more refined. In order not to scratch the surface of mobile phones, a back case is often purchased for the surface of electronic products. Or colored translucent material flexible material, and for the selection of colorful texture, in the currently disclosed technology, the patent with reference publication number is: "CN111497512A" discloses a single-layer gradient color 3D dazzling texture decorative sheet The preparation method, the single-layer gradient color 3D glare texture decorative sheet prepared by it is changed from a two-layer material compo...
