Abstract

The invention discloses an antibacterial and anti-fingerprint paint for mobile phones. The paint comprise the following raw materials by weight: 20-38 parts of a urethane acrylate oligomer, 10-30 parts of epoxy acrylic resin, 2.5-5.5 parts of an antibacterial agent, 15-28 parts of trimethylolpropane triacrylate, 5-9 parts of N-vinyl pyrrolidone, 13-30 parts of 1, 6-hexanediol diacrylate, 3-4.8 parts of a photoinitiator, 8-14 parts of nano-filler, and 0.5-1.3 pars of an assistant. The antibacterial and anti-fingerprint paint for mobile phones provided by the invention has good antibacterial properties and scratch resistance, and excellent antifouling and anti-fingerprint properties.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antibacterial and anti-fingerprint coating for mobile phones. Background technique [0002] In recent years, with the rapid development of smart phones, consumers have higher and higher requirements for mobile phone products. In addition to requiring beautiful colors and comfortable handles, they also require good surface scratch resistance, fingerprint resistance, and excellent stain resistance. At present, there are PET film layers on the back shell of mobile phone products and the surface of the touch screen, but because the PET material has the defects of low surface hardness and poor wear resistance, its service life is shortened. In order to make the film layer scratch-resistant, anti-fingerprint and stain-resistant, and improve its short service life, it is often protected by an ultraviolet curing layer on its surface. However, the antibacterial and fingerprint resist...
