Antifouling and anti-fingerprint coating composite capable of being applied to touch screen panel and preparation method of antifouling and anti-fingerprint coating

Abstract

The invention discloses an antifouling and anti-fingerprint coating composite capable of being applied to a touch screen panel. The antifouling and anti-fingerprint coating composite is characterized by being composed of 10-90 parts of ultraviolet curing film-forming resin, 0-5 parts of a light initiator, 0.1-10 parts of acrylic modified fluorinated resin and 10-90 parts of a solvent. The coating composite is uniformly coated on a substrate to form one layer of optical antifouling and anti-fingerprint coating with good performance through ultraviolet curing so that the contact angle between the antifouling and anti-fingerprint coating and water is more than 80 degrees and the contact angle between the antifouling and anti-fingerprint coating and oleic acid is more than 40 degrees; the antifouling and anti-fingerprint coating composite can effectively prevent dirt including fingerprints, oil stains, sweat and the like from being attached on the surface of the coating; and meanwhile, the coating also has anti-scraping and anti-friction performances and can be widely applied to a display panel of a touch screen.

Description

technical field [0001] The invention relates to an antifouling and antifingerprint coating composition that can be used for touch screen panels. Background technique [0002] As more and more display devices use touch panels, many inevitable problems arise: (1) touch screen panels are easily scratched; (2) touch screen panels are also easily adhered by fingerprints, sweat stains, dust and other dirt , At the same time, it is not easy to erase; thus seriously affecting the service life and visual effect. [0003] Chinese patent 201010140807.7 discloses a fluorine-containing polymer-inorganic nano-hybrid particle modified UV-curable coating and its preparation method, which mainly includes adding hybrid particles of fluorine-containing acrylate monomer into the UV-curable matrix resin Among them, the advantage is that the coating has super-hydrophobic and super-oleophobic functions, and it is suitable for super-amphiphobic modification of UV-curing systems, and at the same ti...

Problems solved by technology

[0002] As more and more display devices use touch panels, many inevitable problems arise: (1) touch screen panels are easily scratched; (2) touch screen panels are also easily adhered by fingerprints, sweat stains, dust and other dirt , and at the same time it is not easy to erase; thus seriously affecting the service life and visual effect

[0004] In order to better suppress fingerprints, sweat, and dirt generated by finger touch on the touch screen, the usual treatment method is to electroplate a layer of inorganic silicon film on the touch screen panel to reduce the surface tension to achieve hydrophobic and anti-fouling, but the investment in coating equipment is expensive. And especially the winding film will produce cracks; or the oxysilane compound additive or the fluorine-based compound additive can be formed into a thin film coating and attached to the substrate. This wet coating is easy to implement, but the antifouling effect is limited, and short life

[0005] The anti-fouling coating obtained by the above technology can only meet the anti-fouling requirements of general daily products. With the increase of use time, the anti-fouling additives are easy to penetrate and migrate on the surface, and can be easily erased and lose the anti-fouling and anti-fingerprint effect. Therefore, with the rapid development of the touch screen display industry, there is an urgent need to have a permanent anti-fouling and anti-fingerprint effect on the screen
