Embodiment Construction

[0025] The technical content, achieved purpose and effects of the present invention are described in detail below.

[0026] Anti-fingerprint paint of the present invention is made by following steps:

[0027] (1) Mixing fluorine-containing polymers with fluorocarbon solvents to obtain fluorine-containing polymer coatings. Specifically, 0.1% to 0.5% of fluorine-containing polymer and 99.5% to 99.9% of fluorocarbon solvent (methoxynonafluorobutane) are mixed to obtain a coating containing fluorine polymer;

[0028] (2) Mix 10g of silica nanoparticles with a particle size of 5-20nm and 100ml of fluorocarbon solvent, then add 0.05-0.2g of fluorine-containing coupling agent, and stir at room temperature for 24 hours. At this time, the silica nanoparticles A layer of fluorine-containing molecules will be modified on the surface of the particles, that is, a silica nanoparticle solution with surface-modified fluorine molecules will be obtained;

[0029] (3) Mix 900ml of the fluorine...

Abstract

The invention discloses a fingerprint-proof paint, a product with a fingerprint-proof coating and a preparation method for the product. The product with a fingerprint-proof coating is prepared by coating the fingerprint-proof paint on the surface of the product. The fingerprint-proof paint is prepared by uniformly mixing a nanoparticle solution with a fluorine-containing coupling agent under agitation so as to obtain a fluorine molecule surface modified nanoparticle solution and then uniformly mixing the fluorine molecule surface modified nanoparticle solution with a paint containing fluorine polymers under agitation. According to the invention, after the fingerprint-proof paint is coated on the surface of a substrate, fluorine-containing polymers and the fluorine-containing coupling agent, which are on the surface of nanoparticles, and the substrate undergo chemical bonding, which enables a fingerprint-proof coating with a thickness of 10 to 100 nm to be formed on the surface of the product; because of low surface energy of fluorine molecules in the fingerprint-proof coating and a stereo barrier formed by the highly regularly arrayed nanoparticles, the product with the fingerprint-proof coating has a good fingerprint-proof effect, and the preparation method for the product is simple.

Description

technical field [0001] The invention relates to a coating and its application, in particular to an anti-fingerprint coating, a product with the anti-fingerprint coating and a preparation method of the product. Background technique [0002] Consumers have higher and higher requirements for mobile phones, personal and industrial computers, PDAs, cameras, ATMs and other electronic products. In addition to having more and stronger functions, they also require more convenience, and touch technology is widely used accordingly. . Therefore, anti-fingerprint (anti-fingerprint) requirements are put forward not only for the casing of the electronic product, but also for the screen of the electronic product. [0003] The substances secreted by the human finger cortex mainly include: about 40% triglycerides (triglycerides), about 25% wax monoesters, about 15% free fatty acids, about 12% squalene and about 7% other substances, all of which are It is oily and oily, and water stains are ...
