Embodiment Construction

[0023] The present invention will be further described below in combination with specific embodiments.

[0024] The invention provides a production method of a ceramic mobile phone case, which is used for continuous production of the ceramic mobile phone case. The production method of described ceramic mobile phone case, comprises the steps:

[0025] Step S1: mixing zirconia ceramic powder, solvent, and binder to form casting slurry;

[0026] Specifically, the solvent is selected from one of organic solvents such as alcohol and toluene; the binder is selected from one of PVB1, PVB2, and PVB3 produced by BASF;

[0027] Step S2: forming a flat shell material through tape casting, degreasing, sintering, and flat grinding processes;

[0028] The specific process includes:

[0029] Obtain a single-layer film tape of 0.1-1mm by tape casting, and obtain a film tape of the required thickness by lamination and isostatic pressing, and then cut the film tape into a certain size produc...

Abstract

The invention discloses a ceramic mobile phone shell production method. The ceramic mobile phone shell production method comprises the following steps of: mixing zirconium oxide ceramic powder, a solvent and a binding agent to form tape casting slurry; forming a flat shell material by tape casting, degreasing, sintering and surface grinding; putting the flat shell material in a mold, putting the mold in a continuous sintering furnace, causing the mold to pass a heating area, a pressurizing area and a cooling area of the continuous sintering furnace, thereby obtaining a 2.5D or 3D ceramic mobile phone shell, wherein the heating temperature of the heating area is controlled to be 1200-1450 DEG C, the forming pressure of the pressurizing area is 0-10000N, the forming time is 0-30 min, and thecooling temperature of the cooling area is 300-450 DEG C. The ceramic mobile phone shell production method has the beneficial effects that the production efficiency is high, the consistency of products is good, and the size control is accurate.

Description

【Technical field】 [0001] The invention relates to the technical field of mobile phone shell preparation, in particular to a production method of a ceramic mobile phone shell. 【Background technique】 [0002] As a modern communication tool, mobile phones are widely used, and with the development of technology, people's pursuit of the texture of mobile phone cases is also constantly improving. Throughout the development and changes of smartphone casings, from plastic, glass, and metal to 2.5D / 3D glass (2.5D means that the upper and lower surfaces are a plane, but a radian is polished at the edge of the plane, and the radian transitions from one surface to the other. Surface; 3D means that the upper and lower sides are not flat, smooth means that there is a large arc at the edge, making it U-shaped as a whole), in just 2-3 years, the manufacturing process of mobile phone cases has continued to evolve and innovate. [0003] In 2016, 2.5D / 3D glass body became one of the developme...
