Embodiment Construction

[0016] see figure 1 A housing 10 in a preferred embodiment of the present invention includes a substrate 11 and a base ceramic layer 13 and a transparent ceramic layer 15 sequentially formed on the surface of the substrate 11 . A pattern layer 17 is also provided between the base ceramic layer 13 and the transparent ceramic layer 15 , and the pattern layer 17 is embedded in the base ceramic layer 13 . The casing 10 can be a casing of an electronic device such as a mobile phone.

[0017] The base material 11 is made of stainless steel or titanium alloy.

[0018] The base ceramic layer 13 is composed of oxide ceramics, which include 60-70% by mass of silicon oxide, 15-20% of aluminum oxide, 5-10% of pigment raw materials, and 5-6% of potassium oxide. , 4-6% sodium oxide, 0.4-0.6% magnesium oxide, 0.2-0.4% iron oxide, 0.2-0.4% calcium oxide. Wherein, the pigment material is a metal compound, specifically titanium oxide, iron oxide, ferric oxide or cobalt oxide, which can respe...

Abstract

A shell body comprises base materials. The shell body is characterized by further comprising a base ceramic layer, a crystalline ceramic layer and a pattern layer, wherein the base ceramic layer is formed on the surface of the base materials, the crystalline ceramic layer is formed on the surface of the base ceramic layer, the pattern layer is arranged between the base ceramic layer and the crystalline ceramic layer, the pattern layer is embedded into the base ceramic layer, and the pattern layer is composed of ceramic. A pattern with ceramic texture is formed on the surface of the shell body, and thus the attractiveness of the appearance of the shell body is improved. Besides, the invention further provides a preparing method for the shell body.

Description

technical field [0001] The invention relates to a casing and a preparation method thereof. Background technique [0002] In order to make the metal casing of the electronic device have an attractive appearance, patterns are mainly formed on the metal casing by methods such as laser engraving and chemical etching. However, the pattern produced by this method has weak visual effect and cannot present a unique texture, so it is difficult to attract the attention of consumers. Contents of the invention [0003] In view of this, it is necessary to provide a housing that effectively solves the above problems. [0004] In addition, it is also necessary to provide a method for preparing the above shell. [0005] A shell, which includes a base material, the shell also includes a base ceramic layer formed on the surface of the base material, a transparent ceramic layer formed on the surface of the base ceramic layer; a pattern layer is also arranged between the base ceramic layer ...
