Embodiment 1

[0049] A method for preparing black mobile phone parts from zirconia ceramics, comprising the following steps:

[0050] 1) Put the zirconia powder without coloring agent directly into the kneader;

[0051] 2), add paraffin or pp organic matter, stir evenly to make a blending material;

[0052] 3) Prepare the blank of zirconia ceramic mobile phone accessories by injection molding or dry pressing;

[0053] 4), and then carry out low-temperature immersion dewaxing in gasoline or white electric oil;

[0054] 5) Put the dewaxed body in the tunnel kiln for high-temperature sintering at 1440-1460°C;

[0055] 6) Place the sintered white zirconia ceramic blank in a vacuum furnace, and place the blank neatly on the graphite plate of the vacuum furnace. According to the product shape, length, width, and thickness, generally stack 3 to 6 layers;

[0056] 7) Spread graphite or activated carbon at the bottom or around the stacked product, and raise the vacuum degree of the vacuum furnace...

Embodiment 2

[0063] A method for preparing titanium-silver mobile phone parts from zirconia ceramics, comprising the following steps:

[0064] 1), put the zirconia powder into the kneader;

[0065] 2), add paraffin or pp organic matter, stir evenly to make a blending material;

[0066] 3) Prepare the blank of zirconia ceramic mobile phone accessories by injection molding or dry pressing;

[0067] 4), and then carry out low-temperature immersion dewaxing in gasoline or white electric oil;

[0068] 5) Placing the dewaxed body in a tunnel kiln for high-temperature sintering at 1420-1460°C to obtain a white zirconia rough body;

[0069] 6) After the white zirconia rough body is sintered, the white zirconia ceramic body is obtained by plane polishing and / or barrel polishing;

[0070] 7) Place the sintered white zirconia ceramic blanks in a vacuum furnace, and place the blanks neatly on the graphite plate of the vacuum furnace. According to the product shape, length, width, and thickness, gen...

Embodiment 3

[0078] A method for preparing pink mobile phone parts from zirconia ceramics, comprising the following steps:

[0079] 1), put the zirconia powder mixed with coloring agent as erbium oxide into the kneader, the mass percent content of erbium oxide is 1.5%;

[0080] 2), add paraffin or pp organic matter, stir evenly to make a blending material;

[0081] 3) Prepare the blank of zirconia ceramic mobile phone accessories by injection molding or dry pressing;

[0082] 4), and then carry out low-temperature immersion dewaxing in gasoline or white electric oil;

[0083] 5) Put the dewaxed body in a tunnel kiln for high-temperature sintering at 1420-1460°C to obtain a zirconia blank corresponding to the colorant;

[0084] 6) After the zirconia rough blank corresponding to the colorant is sintered, it is polished by a 200-12,000-mesh diamond grinding wheel or rolled and polished. The rolling and polishing uses a high-alumina ceramic rod with a mass percentage of 90% and a silicon car...

Abstract

The invention discloses a method for preparing cellphone parts in various colors with zirconia ceramics. The method comprises the following steps: zirconia powder or zirconia powder mixed with coloring agents is injection-molded or drily pressed to prepare blanks, the blanks are immersed for dewaxing, the dewaxed blanks are sintered at a high temperature in a tunnel kiln, the sintered blanks are selectively polished or not polished, then the blanks are resintered under the atmosphere of carbon reduction, and the blanks after being resintered are polished once more to obtain titanium silver zirconia ceramics cellphone parts or black zirconia ceramics cellphone parts; if the zirconia powder is mixed with the coloring agents, the blanks after being sintered at the high temperature in the tunnel kiln are directly polished to obtain zirconia ceramics cellphone parts with colors corresponding to the coloring agents, such as pink zirconia ceramics cellphone parts or yellow zirconia ceramics cellphone parts. The method for shaping and preparing zirconia ceramics cellphone parts through the injection molding process is simple; the consistency of the sizes and the specifications of the cellphone parts is high; the appearance of the cellphone parts is delicate; the tactility of the cellphone parts is good; the cost is low; the disadvantages that existing cellphone parts fade, the paint of the existing cellphone parts is peeled, the existing cellphone parts are scratched, the existing cellphone parts are easily broken and the like, are overcome; and the method can be widely applied to cellphones in mid-to-high price ranges.

Description

【Technical field】 [0001] The invention relates to a preparation process of zirconia ceramics, in particular to a preparation method of zirconia ceramics and mobile phone parts prepared by the method. 【Background technique】 [0002] Modern people have very strict requirements on the quality of mobile phones, so mobile phone accessories must have properties such as non-fading, non-fading, scratch resistance, and drop resistance. [0003] The protective plates, buttons and earpieces in the existing mobile phone accessories are mostly made of plastic, metal or glass materials. Mobile phone parts made of plastic materials are very easy to wear and scratch; mobile phone parts made of metal materials are very easy to scratch. Paint peeling or rusting; and mobile phone parts made of glass are easy to scratch and break, making the protective plate, buttons and earpiece on the mobile phone often have poor wear resistance, easy to scratch, and poor drop resistance, easy to break. 【Co...
