Abstract

The invention provides an anti-fingerprint coating for a mobile phone and a preparation method and particularly relates to the field of anti-fingerprint coatings. The composition is prepared from thefollowing substances in parts by mass, the coating comprises the following components in parts by weight: 30-50 parts of tetramethyl orthosilicate, 5-20 parts of epoxy acrylic resin, 10-15 parts of aphotoinitiator, 1-5 parts of an antibacterial agent, 10-20 parts of heptadecafluorodecyltriethoxysilane, 10-15 parts of N-vinylpyrrolidone, 2-4 parts of a photoinitiator, 10-20 parts of an organic solvent and 5-10 parts of hollow microspheres. The anti-fingerprint coating has excellent oleophobic and hydrophobic properties and a good anti-fingerprint effect, is easy to remove even if leaving traces, and is simple in preparation process, low in cost and suitable for large-scale mass production.

Description

technical field [0001] The invention belongs to the field of anti-fingerprint coatings, in particular to an anti-fingerprint coating for mobile phones and a preparation method. Background technique [0002] As we all know, the screen is the core component of a mobile phone, and it is also the place where smart devices currently occupy the largest body area. Moreover, the screen size of current smartphones and 3C electronic products is more than 7 inches, and even larger is 12 inches; since the screens of these electronic products are all black panels, fingerprints are very easy to fall off when your fingers touch the screen. on the screen surface. If the hands are relatively dry, it is not too obvious after the fingers are touched, but when the user touches with a lot of sweat, the fingerprint screen will be "horrible"; now it is urgent to improve the anti-fingerprint effect of the mobile phone to improve the experience. ; [0003] In view of the above deficiencies, there...
