Problems solved by technology

[0003] There are four types of structures: white glass+AF, AR+AF, AG+AF, AG+AR+AF, which are made by traditional technology, and the surface morphology Ra of the AF bonding layer can only be below 1.0nm. None of them can adjust and optimize the surface morphology through their own process, so that the combination of AF and the underlying film layer is not strong enough. With the AF wear-resistant evaluation method commonly used in the industry, the common white glass + AF cover plate can only achieve 3000-5000 abrasion resistance. The water drop angle is more than 100° after one time; the other three types of covers such as AR+AF

Embodiment 1

[0024] To process the AF layer on the white glass, the main steps are: soft polishing treatment on the surface of the bonding layer of the AF surface to be processed → wet cleaning with pure water → plasma dry cleaning → spraying AF → standing at room temperature for 12 hours.

[0025] The specific steps are:

[0026] 1) Install the 10mm thick high-quality wool wheel to the head of the sander;

[0027] 2) Rotate the grinder, apply a pressure of 1.5kgf, and grind the surface of the AF layer of the white glass to be processed X, Y cross each circle, so as to ensure that each area is polished. The grinding route is as follows: figure 1 As shown, the surface morphology Ra of the substrate after polishing reaches more than 2nm, and the surface morphology of one of the samples is as follows figure 2 As shown; the pressure during the grinding process should not be too heavy, so as not to increase the appearance of grinding and scratching;

[0028] 3) After polishing, use pure wate...

Embodiment 2

[0034] The main steps to prepare the anti-fingerprint touch screen cover plate with white glass + AR + AF structure are: soft polishing treatment on the surface of the bonding layer (AR) on the AF surface to be processed → wet cleaning with pure water → dry cleaning with plasma plasma → spraying AF → static at room temperature Set 12h.

[0035] The specific steps are:

[0036] 1) Install the 10mm thick high-quality wool wheel to the head of the sander;

[0037] 2) Rotate the grinder, apply a pressure of 1.2kgf, and grind the surface of the AF layer of the white glass to be processed X, Y cross each circle, so as to ensure that each area is polished, and the surface morphology of the substrate after grinding Ra reaches above 2nm, and the surface morphology of one of the samples is as follows image 3 The displayed Ra is 2.161nm; the total color difference △E of the color variation before and after polishing is ≤0.25, so as to avoid color change NG and scratch NG caused by exc...

Embodiment 3

[0044] The main steps to prepare the anti-fingerprint touch screen cover plate with the structure of white glass+AG+AR+AF are: soft polishing treatment on the surface of the bonding layer (AR) on the AF surface to be processed→wet cleaning with pure water→plasma dry cleaning→spraying AF→ Stand at room temperature for 12h.

[0045] The specific steps are:

[0046] 1) Install the 10mm thick high-quality wool wheel to the head of the sander;

[0047] 2) Turn the grinder, apply a pressure of 1.0kgf, and grind the surface of the AF layer of the white glass to be processed X, Y cross each circle for a circle, so as to ensure that each area is polished, and the surface morphology of the substrate after grinding The Ra reaches above 2nm, and the surface morphology Rp change of the base material before and after polishing is less than or equal to 0.01μm; the total color difference △E before and after polishing is 0.06, so as to avoid color change NG and scratch NG caused by excessive ...

Abstract

The invention discloses a preparation method of an anti-fingerprint touch screen cover plate. The method specifically comprises the following steps: polishing a bonding layer base material below an AFproduct by using a polishing machine to enable the surface appearance Ra of the base material to reach 2.0 nm or above, and then carrying out AF processing to obtain the anti-fingerprint touch screencover plate. According to the preparation method of the anti-fingerprint touch screen cover plate, soft polishing treatment is added to the surface of the base material of the AF to be processed, sothat the surface appearance of the bonding layer base material of the AF reaches 2.0 nm or above, and the abrasion resistance of the finally obtained AF product can reach the water drop contact angleof 100 degrees or above after 10000 times; and for mobile phone consumer electronics of a white glass + AF structure, the anti-fingerprint effect of the prepared product is prolonged by 2-3 times, andfor AR + AF, AG + AF and AG + AR + AF touch screen products, the anti-fingerprint effect is prolonged by 5 times or above.

Description

technical field [0001] The invention relates to the technical field of anti-fingerprint film indicators, in particular to a preparation method of an anti-fingerprint touch screen cover. Background technique [0002] Anti-fingerprint AF touch screen cover, the main application fields are: white glass + AF structure, used for mobile phone touch screen cover, tablet computer touch screen cover, etc.; AR + AF structure, used for touch computer display screen, TV display screen, etc.; AG+AF structure, used for medical and other industrial touch screen covers; AG+AR+AF structure, used for vehicle display screens, etc. [0003] There are four types of structures: white glass+AF, AR+AF, AG+AF, AG+AR+AF, which are made by traditional technology, and the surface morphology Ra of the AF bonding layer can only be below 1.0nm. None of them can adjust and optimize the surface morphology through their own process, so that the combination of AF and the underlying film layer is not strong e...
