High-wear-resistance and high-water-contact-angle hardened film

Abstract

The invention discloses a high-wear-resistance and high-water-contact-angle hardened film which comprises a transparent base material, a bottom coating layer and an AF layer which are sequentially attached from bottom to top; the bottom coating layer is formed by coating the transparent base material with a bottom coating solution for light curing, the AF layer is formed by coating the bottom coating layer with an AF coating solution for heat curing, and the bottom coating solution comprises the components in parts by weight: 10 to 50 parts by weight of a polyurethane acrylate resin oligomer with the functionality of 4 to 20 and the molecular weight of 800 to 5000, 2 to 30 parts by weight of allyl-modified terminal allyl phenolic resin with the functionality of 5 to 30 and the molecular weight of 500 to 5000, 0.3 to 3 parts by weight of a flatting agent, 0.5 to 2.5 parts by weight of a photoinitiator, and 30 to 80 parts by weight of an organic solvent; and an AF coating liquid is a perfluoropolyether coating liquid with the solid content of 0.1% to 2% and with an end group modified by siloxane. The high-wear-resistance and high-water-contact-angle hardened film has the advantages of low friction coefficient, high water contact angle, simple process, low manufacturing cost and benefit for mass production.

Description

technical field [0001] The invention relates to a hardened film, in particular to a hardened film with high wear resistance and high water contact angle. Background technique [0002] With the popularization of electronic products such as smart phones, these electronic products have increasingly become an indispensable part of people's daily life. Because of this, people's demand for electronic products has gradually extended from the pure product performance to more stable, faster and more convenient products, and gradually extends to the requirement that the products themselves have waterproof, no fingerprints after touching, and super smooth touch. sexual needs. In particular, the ultra-smooth touch of the electronic screen is the ultimate experience pursued by countless mobile game players. In order to increase consumers' excellent experience and satisfaction with smart phones and other electronic products, the anti-fingerprint (AFAnti-fingerprint) and super smooth eff...

Problems solved by technology

In this film, since the adhesion between the primer layer and the AF layer is not high, in order to improve the bonding firmness between the two and ensure the wear resistance, an additional bonding stability layer is added to ensure that the primer layer and the AF layer The firmness of the combination leads to its complicated process, which increases the material cost and process cost, and the manufacturing cost is relatively high
