Embodiment 1

[0028] A substrate is provided, on which a chromium carbide layer and a titanium nitride layer are sequentially formed. Both the chromium carbide layer and the titanium nitride layer are formed by vacuum coating.

[0029] Preparation of anti-fingerprint agent: provide a silane solution. The silane solution mainly consists of methyltriethoxysilane, ethyl orthosilicate, absolute ethanol, deionized water and dilute sulfuric acid. Wherein, the volume percentage of methyltriethoxysilane is 60%, the volume percentage of ethyl orthosilicate is 2%, the volume percentage of absolute ethanol is 2%, the volume percentage of deionized water is 25% and The volume percentage of dilute sulfuric acid is 5%. The mass percent content of dilute sulfuric acid used to configure the silane solution is 45%.

[0030] Mix the liquid polytetrafluoroethylene and the silane solution at a volume ratio of 0.6:1 to prepare a mixed solution, stir evenly and let stand for 30 minutes; after that, filter the...

Embodiment 2

[0033] A substrate is provided, which is the same as that provided in Example 1.

[0034] Preparation of anti-fingerprint agent: provide a silane solution. The silane solution mainly consists of methyltriethoxysilane, ethyl orthosilicate, absolute ethanol, deionized water and dilute sulfuric acid. Wherein, the volume percentage of methyltriethoxysilane is 63%, the volume percentage of ethyl orthosilicate is 3%, the volume percentage of absolute ethanol is 3%, the volume percentage of deionized water is 26.5% and The volume percentage of dilute sulfuric acid is 9%. The mass percent content of dilute sulfuric acid used to configure the silane solution is 45%.

[0035] Mix the liquid polytetrafluoroethylene and the silane solution at a volume ratio of 0.8:1 to prepare a mixed solution, stir evenly and let stand for 40 minutes; after that, filter the mixed solution to remove a small amount of suspended impurities to obtain the anti-fingerprint agent.

[0036] Forming an anti-f...

Embodiment 3

[0038] An anti-fingerprint layer was formed on the substrate in the same manner as in Example 2, except that a zirconium nitride layer was formed on the substrate instead of the chromium carbide layer and titanium nitride layer. The zirconia layer is formed by vacuum coating.

Abstract

An anti-fingerprint agent is mainly composed of polytetrafluoroethylene and silane solutions. The volume ratio of the polytetrafluoroethylene and the silane solutions is 0.5-0.8. The silane solutions are mainly composed of methyl triethoxysilane, ethyl orthosilicate, absolute ethyl alcohol, deionized water and dilute sulphuric acid. The invention further provides a method and a product applying the anti-fingerprint angent to conduct surface treatment.

Description

technical field [0001] The invention relates to an anti-fingerprint agent, a surface treatment method and a product using the anti-fingerprint agent. Background technique [0002] As 3C electronic products are used more and more frequently, consumers have higher and higher requirements for the appearance of products. In addition to the requirements of beautiful color and comfortable hand feeling, the surface is also required to have good wear resistance, scratch resistance and fingerprint resistance. In order to improve the anti-fingerprint property of the surface of the vacuum coating layer, the anti-fingerprint layer formed by vacuum coating technology in the prior art usually appears foggy, which seriously affects the high-gloss metallic appearance of the vacuum coating product. [0003] In the prior art, a polytetrafluoroethylene layer is deposited on the vacuum coating layer to make the vacuum coating product have good fingerprint resistance. However, the bonding forc...
