preparation example Construction

[0038] The preparation method of the above-mentioned anti-fingerprint hardened film of the present invention may include the following steps: first, coating the anti-fingerprint hardened film on the surface of a substrate to form a hardened coating; then, performing photocuring on the above-mentioned hardened coating to obtain the above-mentioned anti-fingerprint Fingerprint hardening film. Those skilled in the art can set the process conditions of the above-mentioned coating process and photocuring treatment according to the existing technology. Before the anti-fingerprint hardened film is coated on the surface of the substrate, the above-mentioned preparation method may also include the step of diluting the anti-fingerprint coating solution, and the solid content of the anti-fingerprint coating solution after dilution is 20% to 50%, preferably 25% to 50%. 45%, more preferably 30-40%. Limiting the content of the organic solvent to the above preferred parameter range can enab...

Abstract

The invention provides an anti-fingerprint coating liquid and an anti-fingerprint hardening film. The anti-fingerprint coating liquid is prepared from components, in percentage by weight, 20%-50% of fluorine-containing acrylic acid prepolymers, 10%-40% of matrix resin, 1%-5% of a photoinitiator and 30%-50% of an organic solvent. The components of the anti-fingerprint coating liquid are limited in the content range, the fluorine-containing acrylic acid prepolymers can be rapidly subjected to a polymerization reaction under the action of the photoinitiator through UV illumination, fluoride elements float on the surface of the matrix resin, the fluorine-containing aid is added to improve the content of the fluoride elements on the surface and improve the levelling property of the coating liquid, after the anti-fingerprint coating liquid is cured to form an anti-fingerprint coating, the smooth degree and the wear resistance of the surface of the anti-fingerprint coating can be improved, and the anti-fingerprint coating has better hydrophobic performance.

Description

technical field [0001] The invention relates to the field of material technology, in particular to an anti-fingerprint coating liquid and an anti-fingerprint hardened film. Background technique [0002] In today's society, electronic products have been widely used. Fingerprints are easy to remain on the surface of the external display screen during use, causing the surface to be dirty. When the screen is scratched, a large number of scratches are likely to occur, which affects the appearance and appearance of electronic products. Normal use will cause a great impact. A commonly used solution to the above problems is to paste a layer of anti-fingerprint protective film on the surface of electronic products. However, the above-mentioned anti-fingerprint protective film is easy to generate air bubbles during the bonding process, which greatly affects the appearance and display of the display screen. quality. [0003] The external screens of electronic products currently in us...
