Problems solved by technology

Although the anti-fingerprint film for the touch screen can effectively prevent the screen from being polluted by the outside world, it cannot prevent other appearance parts of the product from being polluted by the outside world. Therefore, with the rapid development of electronic products, each surface of the electronic product is waterproof, antifouling, anti If the fingerprint performance is too poor, it will not be able to meet the market demand

Embodiment 1

[0040] A modified AF coating material, comprising AF raw material and a modifier, the mass ratio of the AF raw material to the modifier is 20:2.5.

[0041] The AF raw material comes from Merck WR6 series coating film material in Germany. WR6 is specially designed for the production of hydrophobic and oleophobic coatings to meet the mature anti-fingerprint, anti-smudge and easy-to-clean surface treatment technology market demand in today's touch screen market , using the method of vacuum evaporation, WR6 can significantly reduce the adhesion of dust and fingerprints on the sensing surface of the touch screen, thus providing an excellent ease of operation.

[0042] The modifying agent includes fatty acid lead salt, methyl hexahydrophthalic anhydride, 4-nonylbenzene powder, nano-layer increasing agent and butylphenol, and the modifying agent is based on the mass ratio of fatty acid lead salt: methyl Hexahydrophthalic anhydride: 4-nonylbenzene powder: nano-layer enhancer: butylphe...

Embodiment 2

[0050] A modified AF coating material comprises AF raw materials and modifiers, and the mass ratio of the AF raw materials to the modifiers is 20:3.

[0051] The AF raw material comes from the EC300X series of PPG in the United States.

[0052] The modifying agent includes fatty acid lead salt, methyl hexahydrophthalic anhydride, 4-nonylbenzene powder, nano-layer increasing agent and butylphenol, and the modifying agent is based on the mass ratio of fatty acid lead salt: methyl Hexahydrophthalic anhydride: 4-nonylbenzene powder: 4-aminobiphenyl: butylphenol = 1:1:1:1:2.

[0053] The nano-layer increasing agent is 4-aminobiphenyl.

[0054] The butylphenol is a mixture of di-tert-butylphenol and sec-butylphenol with a mass ratio of 1:1.

[0055] The modifier also includes bicyclooctane, dioxane, di-n-octyl-bis(2-ethylhexyl mercaptoacetate) tin.

[0056] The bicyclooctane is a combination of cis-isomerization and trans-isomerization, and the mass of the bicyclooctane accounts ...

Embodiment 3

[0060] A modified AF coating material, comprising AF raw material and modifier, the mass ratio of the AF raw material to the modifier is 20:3.5.

[0061] The AF raw material comes from Duen superhard waterproof membrane SH-HT9080.

[0062] The modifying agent includes fatty acid lead salt, methyl hexahydrophthalic anhydride, 4-nonylbenzene powder, nano-layer increasing agent and butylphenol, and the modifying agent is based on the mass ratio of fatty acid lead salt: methyl Hexahydrophthalic anhydride: 4-nonylbenzene powder: nano-layer enhancer: butylphenol=1:1:1:1:2.

[0063] The nano-layer increasing agent is 4-aminobiphenyl.

[0064] The butylphenol is a mixture of di-tert-butylphenol and sec-butylphenol with a mass ratio of 1:1.

Abstract

The invention discloses a modified AF coating material and its preparation method and application. The modified AF coating material includes an AF raw material and a modifier, and the mass ratio of the AF raw material to the modifier is 20:2.5-3.5 , the modifying agent includes fatty acid lead salt, methyl hexahydrophthalic anhydride, 4-nonylbenzene powder, nano-layer increasing agent and butylphenol, and the modifying agent is by mass ratio fatty acid lead salt: methyl Base hexahydrophthalic anhydride: 4-nonylbenzene powder: nano-layer enhancer: butylphenol=1:1:1:1:2. The invention improves the anti-fouling, anti-fingerprint, hydrophobicity and adhesion of the material by modifying the original AF raw material and increasing the thickness of the nano coating.

Description

technical field [0001] The invention belongs to the technical field of optical coating materials, in particular to a modified AF coating material and its preparation method and application. Background technique [0002] AF coating is based on the principle of lotus leaf, coating a layer of nano-chemical materials on the surface of the glass to make it have strong hydrophobicity, anti-oil, anti-fingerprint and other functions. It can easily wipe off dirt, finger prints, oil stains, etc., making the surface smoother and more comfortable to the touch, achieving the effect of waterproof, anti-fouling, and anti-fingerprints. AF coating materials are mainly used in glass coating, such as mobile phone 3D glass coating. [0003] Such as Chinese utility model patent, application number is 201120330917.X, discloses an anti-fingerprint film for touch screen, the upper surface of strengthened glass is a buffer layer, the upper surface of the buffer layer is AF film, and the buffer laye...
