Problems solved by technology

For example, a Chinese patent application (publication number: 103232171A) discloses a glass cover for a touch screen and a preparation method thereof. The glass cover for a touch screen is made by first tempering ultra-thin glass and then coating a layer of diamond-like film. Although it can improve the scratch resistance and impact resistance of the glass cover plate, due to the large internal stress of the film deposited on the surface of the glass substrate, the formed film is easy to release, which restricts the development of the film.

Embodiment 1

[0023] The size of the glass substrate can be adjusted according to actual needs. For example, according to the size of the display screen of a mobile phone or a computer display screen, the Corning glass substrate with a thickness of 0.7 mm is preferably used in the present embodiment, and the Corning glass substrate with a thickness of 0.7 mm The sheet was washed with deionized water, lye degreasing, isopropanol degreasing, and deionized water successively for 15 minutes. After the above-mentioned treatment, the oil stains and other stains on the surface of the glass substrate were removed, and then dried for later use; the above-mentioned treated After the glass substrate is clamped (according to the conventional clamping method), it is put into the coating chamber of the vacuum coating machine. The vacuum coating machine can adopt a conventional vacuum coating machine, and then, vacuumize the coating chamber. Make the vacuum in the coating chamber reach 5.0x10 -5 At the sa...

Abstract

The invention relates to a preparation method of diamond-like film glass and belongs to the technical field of glass coating. In order to solve the conventional problems of poor binding force and low hardness, the preparation method of the diamond-like film glass is provided and comprises steps as follows: a glass substrate is clamped and placed in a film coating chamber, argon is introduced into the film coating chamber after vacuum pumping, plasma is generated, and plasma cleaning is performed; after cleaning, argon supply is stopped, the film coating chamber is subjected to vacuum pumping again, then argon is introduced again, a carbon target emission source is opened simultaneously, a pulse direct-current power supply is started, plasma is generated, and a diamond-like film is deposited; the diamond-like film is formed by alternating depositing of a diamond-like film with high sp <2> bond content and a diamond-like film with low sp <2> bond content; after deposition is finished, an AF (anti-fingerprint) film is deposited on the surface of the diamond-like film, and the diamond-like film glass is obtained. The product obtained with the method has better binding force, high scratch resistance, high wear resistance, anti-fingerprint and anti-dust effects and non-conductive performance.

Description

technical field [0001] The invention relates to a method for preparing diamond-like film glass, which belongs to the technical field of glass coating. Background technique [0002] With the rapid development of information technology and flat-panel display technology, touch screen has played a pivotal role in all walks of life as a symbol of the progress of the times, especially in electronic products such as smart phones and tablet computers. At the same time, the large demand of consumers for touch screen products and the technological progress of the industry have further promoted the continuous development of touch screen technology. [0003] As far as the touch screen itself is concerned, the outermost protective element of the glass cover touch screen has very high performance requirements. It needs to have the characteristics of high light transmittance, scratch resistance, impact resistance and portability. Ultra-thin glass, now commonly used 0.7mm soda-lime glass, ...
