Abstract

The invention disclose a mobile phone rear cover with a metal texture, which comprises a mobile phone rear cover matrix and a metal compound coating. A mainboard electronic component is arranged in the mobile phone rear cover matrix, and the mobile phone rear cover matrix is prepared from zirconia; the metal compound coating is prepared by the following method of: spraying a metal material on the surface of the mobile phone rear cover matrix by magnetron sputtering, thermal spraying of electric arc heat, supersonic thermal spraying or plasma thermal spraying so as to form a metal thin film; and oxidizing the metal thin film by corrosion treatment so as to form a metal compound, wherein a thickness of the metal compound occupies for 70 to 80% of a thickness of the metal thin film. Correspondingly, the invention further discloses a preparation method of the mobile phone rear cover. By adopting the mobile phone rear cover and the preparation method thereof, which are disclosed by the invention, not only is an effect that appearance of a metal housing has the unique texture and touch sense of metal achieved, but also a thickness of a mobile phone is reduced by one fifth, cost of the mobile phone is reduced by two thirds, and radio transmission efficiency of the mobile phone is improved by over 2 times.

Description

technical field [0001] The invention relates to the field of mobile phone back covers, in particular to a mobile phone back cover with a metallic texture and a preparation method thereof. Background technique [0002] From the first mobile phones in the field to the current 4G smartphones, extending to the upcoming 5G era, the functions of mobile phones are becoming more and more powerful. The back cover of the mobile phone started from plastic at the beginning, and now plastic, glass, metal and other materials coexist. The diversification of the back cover of the mobile phone meets the needs of different customers. Moreover, in most cases, based on the characteristics of low cost and strong plasticity of plastics, they are mainly used in low-end and mid-range mobile phones. Glass is mainly used in the medium and high-end stages. As for metal, based on its unique texture and touch, it is mainly used in high-end mobile phones. In addition, its process is complicated and the...
