Abstract

The invention discloses ultraviolet light curing anti-fingerprint paint, which comprises components with percentage by weight of 5-25 wt% high function aliphatic polyurethane acrylic ester, 10-30 wt% acrylic ester modified by fluorine, 5-20 w% large molecular resin, 10-25 wt% trifunctionanal function aliphatic polyurethane acrylic ester, 5-15 wt% double function acrylic ester, 1-5 wt% photo initiator, 15-40 wt% diluent and 0.01-1 wt% auxiliary agent, wherein high function aliphatic polyurethane acrylic provides hardness and high abrasion resistance, acrylic ester modified by fluorine is formed by grafting fluorine monomer with acrylic ester. The anti-fingerprint paint can permanently reduce the surface tension of painting film, and eliminates the generation of fingerprints.

Description

Technical field [0001] The invention relates to an ultraviolet curing coating, in particular to a coating for anti-fingerprint protection on the surface of digital products. Background technique [0002] Portable electronic products have become fast-moving consumer goods, becoming more and more a part of people's lives, and their appearance requirements are getting higher. Portable electronic products such as mobile phones, laptops, MP3s, and digital cameras often need to be touched by hands. After coating, the casing is as bright as a mirror. Once stained with fingerprints, hand sweat, body oil and other stains, it is difficult to remove it. The beauty of the product, [0003] Chinese patent CN1778851 is a surface anti-fingerprint coating, which includes: a hydrophobic nano material coating, an oleophobic nano material coating or an ultra-double hydrophobic nano material coating formed on the surface of the substrate to be coated. Wherein, the hydrophobic nano-material coating i...
