preparation example Construction

[0022] An embodiment of the present invention provides a method for preparing a glass case, comprising the following steps:

[0023] crushing the glass matrix and mixing it with a binder to obtain a mixture;

[0024] Drying the mixture to obtain glass shell powder;

[0025] Fill the glass shell powder into the preset mold, and press to obtain the pre-finished glass shell;

[0026] A sintering process is performed on the glass envelope preform.

[0027] In the preparation method of the glass shell in this embodiment, the pulverized glass matrix powder is mixed with a binder, and then dried to remove the moisture in the mixture and prevent bubbles and pinholes inside the glass shell, which is beneficial to improve the glass shell. density. Filling the glass shell powder into a preset mold and pressing to obtain a glass shell preform, and then sintering the glass shell preform to obtain a glass shell. The preparation method does not need to cut the whole piece of glass, which...

Embodiment 1

[0045] The glass-ceramic substrate is taken and pulverized by a ball mill to form a slurry with a particle size of 1 μm-10 μm. In the slurry, add 3% polyvinyl alcohol accounting for the quality of the glass-ceramic substrate as a binding agent, and 4% cobalt blue material accounting for the quality of the glass-ceramic substrate as a colorant, so that the slurry, adhesive The binder and the colorant are thoroughly mixed to obtain a mixture.

[0046] The mixture is dried by a centrifugal dryer, the rotational speed of the centrifugal nozzle of the dryer is 250r / s, and the temperature of the drying chamber is 280°C. After drying, a glass shell powder is obtained.

[0047] Fill the glass shell powder into the preset mold, hold the pressure for 10s under the pressure of 25MPa, and press to obtain the pre-finished glass shell.

[0048] The glass shell preform is moved into a sintering furnace for sintering. After debinding at 400°C for 1 hour, sintering at 600°C for 30 minutes, ...

Embodiment 2

[0051] The glass-ceramic substrate is taken and pulverized by a ball mill to form a slurry with a particle size of 1 μm-10 μm. In this slurry, add the polyvinyl alcohol that accounts for 5% of the quality of glass-ceramics matrix as binder, and account for the cobalt black material of 4% of the quality of glass-ceramics matrix as pigment, make slurry, bonding The agent and the colorant are mixed thoroughly to obtain a mixture.

[0052] The mixture was dried by a centrifugal dryer, the rotational speed of the centrifugal nozzle of the dryer was 220r / s, and the temperature of the drying chamber was 265°C. After drying, a glass shell powder is obtained.

[0053] Fill the glass shell powder into the preset mold, hold the pressure for 10s under the pressure of 25MPa, and press to obtain the pre-finished glass shell.

[0054] The glass shell preform is moved into a sintering furnace for sintering. After debinding at 400°C for 1 hour, sintering at 600°C for 30 minutes, and sinteri...

Abstract

The invention relates to a preparation method of a glass shell, the glass shell and an electronic device. According to the preparation method, crushed glass matrix powder and a binder are mixed and subjected to drying treatment, moisture in the mixture is removed, bubbles and pinholes are prevented from appearing in the glass shell, and improvement of the compactness of the glass shell is facilitated. Glass shell powder is filled into a preset mold to be pressed to obtain a glass shell pre-finished product, and then the glass shell pre-finished product is sintered to obtain the glass shell. The preparation method starts from a preparation source of the glass shell, the whole glass does not need to be cut, and cutting waste can be effectively avoided. Meanwhile, the preparation method can be used for preparing the glass shell with the corresponding thickness according to production requirements, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of electronic equipment manufacturing, in particular to a method for preparing a glass casing, the glass casing and electronic equipment. Background technique [0002] With the advancement of technology, more and more electronic devices have entered people's lives, and multi-functional electronic devices are deeply loved by consumers. After years of development, consumers have higher and higher requirements for electronic equipment. On the premise of satisfying various functions, consumers hope that the appearance of electronic equipment will be more exquisite. Glass itself has good performance and a good decorative effect, so more and more electronic equipment casings are now made of glass materials. However, the traditional glass casing is processed by cold engraving, that is, a piece of thick glass is used as a raw material, and the casing structure of the electronic device is carved out by a precision ...
