Problems solved by technology

[0003] In the prior art, it is generally chosen to coat a coating containing inorganic particles on the surface of a transparent substrate, and achieve diffuse reflection through the concave-convex structure formed by the particles on the surface of the coating, so as to achieve an anti-glare effect; The personnel found that due to the poor dispersion of inorganic particles, the dispersion in the coating is uneven, and the unevenness of the surface of the substrate is also uneven, so the anti-glare effect is poor.

Abstract

The invention discloses a nano anti-fingerprint anti-dazzle film and a preparation process thereof. Magnetic silicon dioxide is selected and introduced, dispersion improvement is conducted on the magnetic silicon dioxide through a dispersing agent to obtain a magnetic filler, the dispersing agent is tween-20, terminal hydroxyl of the tween-20 can be bonded with hydroxyl on the surface of silicon dioxide, and adsorption is conducted to improve the dispersing performance of the magnetic silicon dioxide, and the magnetic filler with excellent dispersity is obtained. According to the nano anti-fingerprint anti-dazzle film and the preparation process thereof, the process design is reasonable, the operation is simple, and the prepared anti-dazzle film not only has excellent anti-dazzle performance, but also has hydrophobic surface and excellent anti-fouling and anti-fingerprint performance; and magnetic fillers with different particle sizes are adopted for directional arrangement so the prepared anti-dazzle film is excellent in wear resistance and relatively high in practicability.

Description

technical field [0001] The invention relates to the technical field of anti-glare films, in particular to a nano anti-fingerprint anti-glare film and a preparation process thereof. Background technique [0002] Anti-glare film, referred to as AG film for short, can reduce the reflected light of the processed surface and reduce the interference of light on vision. The overall appearance is foggy, but the light transmittance is good and does not affect the viewing effect. The anti-glare film can be widely used in technical fields such as mobile phone screen protection and electronic devices. [0003] In the prior art, it is generally chosen to coat a coating containing inorganic particles on the surface of a transparent substrate, and achieve diffuse reflection through the concave-convex structure formed by the particles on the surface of the coating, so as to achieve an anti-glare effect; The personnel found that due to the poor dispersion of the inorganic particles, the dis...
