Ceramic mirror and manufacturing method thereof

Abstract

The invention discloses a ceramic mirror which comprises a ceramic substrate and mirror coating. The mirror coating is attached to the ceramic substrate, and target materials of the mirror coating arealuminum, indium, tin, indium tin alloy and other metal materials. According to the ceramic mirror and the manufacturing method thereof, the prepared ceramic mirror has the following advantages that1, the ceramic mirror is high in hardness, abrasion resistant and high-end and elegant; 2, the ceramic mirror is of amorphous material, the ceramic mirror is not prone to broke, splash and hurt people; 3, the ceramic mirror is thinner, the thickness is almost half of that of a glass mirror, the thinnest thickness can be 0.4 mm, when wireless charging conducting material is used, a wireless charging coil is closer to a receiving coil, and the conducting effect is better; 4, the ceramic mirror has high dielectric constant, no shielding signals, the ceramic mirror is very suitable for using as anelectromagnetic or signal conduction scenario; and 5, fingerprint-proof treatment is achieved, and the ceramic mirror is not prone to being stained with oil and fingerprints, and is easy to wipe.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a ceramic mirror and a manufacturing method. Background technique [0002] With the acceleration of people's life rhythm, there are more and more intelligent electronic products, more and more diversified, and the combination is superimposed. Mirrors are essential items in the daily life of women who love beauty. In order to meet the needs of women, many products effectively combine mirrors with charging treasures, wireless chargers, MP3 players, mobile phones, etc. to form electronic products with mirror functions, which makes The lens surface originally protected by the shell will become exposed. The original problems of glass mirrors without shell protection are exposed in use, such as: fragile, splashing and hurting people, easy to get dirty, heavy and so on. Some people also use stainless steel to make mirrors, which can make the mirror thinner, but the hardness of stainless steel...

AI Technical Summary

Problems solved by technology

[0003] In the current technology, stainless steel is the mirror base material. Due to the low hardness of stainless steel and easy scratches and other problems, it has not been accepted by the market. Most of the mirrors are mainly glass mirrors.

[0004] 1. High brittleness, fragile and hurting people by splashing;

[0005] 2. Easy to get dirty, when used as an appearance part, it is easy to stick fingerprints and oil stains;

[0006] 3. Thick and heavy, generally greater than 1mm, when used as a transition layer for wireless charging, it will also have a greater impact on charging efficiency;

[0007] 4. The production process is seriously polluted;

[0008] Due to the above defects, the existing glass mirror materials are rarely used as exterior parts, and generally need to be protected

The stainless steel lens is easy to scratch and is not suitable as an appearance part, especially when used as a wireless charging or mobile phone case, it will seriously shield the charging magnetic field and signal
