Antibacterial photocuring printing ink

Abstract

The invention relates to the photocuring field, in particular to an antibacterial photocuring printing ink. The antibacterial photocuring printing ink comprises, by weight, 15-25 parts of adipic acid divinyl esters, 20-30 parts of polyurethane modified acrylic resin, 5-15 parts of pigment, 5-15 parts of nanometer titanium dioxide, 3-8 parts of nanometer bamboo charcoal fibers, 2-6 parts of photoinitiators, 2-6 parts of graphene and 1-4 parts of assistants. The antibacterial photocuring printing ink has good bacteria resistance and inhibition functions.

Description

technical field [0001] The invention relates to the field of photocuring, in particular to an antibacterial photocuring ink. Background technique [0002] Because of its ability to produce economical, high-quality, color prints, inkjet technology has expanded its application to high-speed, commercial and industrial printing in addition to home and office use. The technology is a pressureless printing method in which electronic signals control and direct ink droplets or streams that can be deposited onto a wide variety of substrates. Inks used in such techniques may be liquid dispersions, solutions or emulsions, and may include oil-based inks, non-aqueous solvent-based inks, water-based inks, and solid inks. Current inkjet printing techniques involve propelling ink droplets through small nozzles onto the surface of the media by thermal spraying, piezoelectric pressure, or vibration. The deposited ink droplet is then dried, for example by heating or using a pressurized air s...
