Preparation method of gradient three-dimensional pattern mobile phone backboard

Abstract

The invention discloses a preparation method of a gradient three-dimensional pattern mobile phone backboard. The preparation method comprises the following steps: S1, pre-forming a backboard substrate; s2, cleaning and drying the mobile phone backboard base material; s3, carrying out fine carving processing on the three-dimensional pattern; s4, carrying out secondary cleaning and drying; s5, carrying out gradient color processing on the three-dimensional pattern; s6, processing a texture layer; s7, carrying out hardening treatment; and S8, cleaning to obtain the gradient three-dimensional pattern mobile phone backboard. The first groove, the first step protrusion, the second step protrusion and the center protrusion are arranged to form the step protrusion structure, and the first pattern, the second pattern and the logo pattern are finely carved on the surface of the step protrusion structure, so that the three-dimensional pattern is obtained; and then the first gradient color layer is formed on the surface of the first pattern, the second gradient color layer is formed on the surface of the second pattern, and the logo gradient color layer is formed on the surface of the logo pattern, so that the mobile phone backboard has gradient color three-dimensional patterns, the appearance display effect of the mobile phone backboard is improved, and the ornamental value is improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone back plates, in particular to a method for preparing a mobile phone back plate with gradient three-dimensional patterns. Background technique [0002] In daily life, mobile phones have become an indispensable communication tool for people. With the continuous upgrading of mobile phones, people's needs for mobile phones are becoming more and more diverse. Requirements are also more and more important. The appearance of the existing mobile phone backplane is mostly a single solid color, and the color is monotonous. There are scratches or color decay on the surface of the mobile phone back panel, which affects the appearance effect, and the existing mobile phone back panel patterns are mostly flat patterns, and the appearance effect of the three-dimensional pattern with gradient colors cannot be obtained, which cannot meet people's needs for multi-color Demand for mobile phone back panels with ...
