Embodiment Construction

[0021] The invention provides a method for increasing the hardness and wear resistance of ultra-thin glass, comprising the following steps:

[0022] S1. Take a glass substrate with a thickness of 1.1 mm or less, clean the glass substrate, remove stains on the surface of the glass substrate and dry it;

[0023] S2. Put the cleaned glass substrate into the magnetron sputtering coating equipment, when the vacuum degree of the magnetron sputtering vacuum chamber is 2.5*10 -3 At Pa, bake the magnetron sputtering vacuum cavity, the baking temperature is 60-65°C, the baking time is 20-30min, and the impurity molecules in the magnetron sputtering vacuum cavity are discharged;

[0024] S3. After the baking is finished, use zirconium as the target material and use the radio frequency power supply to carry out the pre-sputtering step first. The purpose of the pre-sputtering is to make the target material glow and remove impurities on the target material surface. The power of the radio fr...

Abstract

The invention discloses a method for increasing the hardness and the wear resistance of ultra-thin glass. The method comprises the following steps: S1. cleaning glass substrate, removing stains on thesurface of the glass substrate, and blow-drying; S2. putting the cleaned substrate into a magnetron sputtering coating device, baking a magnetron sputtering vacuum chamber, and discharging impuritiesin the magnetron sputtering vacuum chamber; S3. after baking, adopting a radio-frequency power supply, taking zirconium as a target material as well as argon and oxygen as sputtering gases, and depositing a zirconia thin film on the surface of the glass substrate on one side through magnetron sputtering; S4. overturning the glass substrate, and adopting a process the same as step S3 to deposit zirconia thin film on the surface of the glass substrate on the other side. Double-sided coating ensures the mechanical strength of coated glass, and the other side is difficult to damage when one sideis subject to force impact; the technological process can be precisely controlled, so that controllable thickness of zirconia thin film is ensured, and the requirement of transmittance is met.

Description

technical field [0001] The invention relates to the technical field of ultra-thin glass manufacturing, in particular to a method for increasing the hardness and wear resistance of ultra-thin glass. Background technique [0002] In order to increase the hardness of glass and improve its applicability, glass is generally treated by tempering at this stage. Tempered glass is very popular in today's market because of its high mechanical strength, good elasticity, high thermal stability, and it is not easy to hurt people after being broken. In the building materials and automobile industries, physically tempered thick glass has become a hot commodity, while in electronic products, chemically tempered glass is the best. The two have deep-processed the glass through different means. [0003] However, among the two tempering methods currently on the market, the process of chemically tempering glass is relatively complicated, the cost is high, and ultra-thin glass cannot be tempere...
