Abstract

The invention relates to the field of water-based ink preparation and discloses anti-ultraviolet nano cobalt zinc oxide water-based ink and a preparation method. The preparation method comprises the following steps: (1) mixing zinc nitrate, cobalt nitrate, cetyl trimethyl ammonium bromide and urea, stirring, and heating so as to obtain a nano cobalt zinc oxide; (2) diluting the water-based ink with distilled water, and uniformly mixing with a dispersant so as to obtain a water-based ink mixed liquid; (3) putting 3-5% by mass of the water-based ink mixed liquid into the nano cobalt zinc oxide,and performing ultrasonic dispersion, thereby obtaining an anti-ultraviolet nano cobalt zinc oxide water-based ink material. Compared with conventional anti-ultraviolet water-based ink, the anti-ultraviolet water-based ink provided by the invention is good in anti-ultraviolet absorption property and shielding effect, good in thermal resistance, high in chemical stability, long in service life, good in environment protection, simple and easy in preparation process control, easy in raw material obtaining, low in production cost and good in application prospect.

Description

technical field [0001] The invention relates to the field of preparation of water-based ink, and discloses a nano-cobalt zinc oxide water-based ink for anti-ultraviolet rays and a preparation method. Background technique [0002] The traditional solvent-based inks widely used in the printing industry are mainly organic solvents such as aromatic hydrocarbons, esters, ketones, ethers, etc., which are generally toxic and will pollute the packaged products and the environment. Affect the health of the human body, and there are hidden dangers in production safety at the same time. Therefore, the application of green and environmentally friendly water-based inks is becoming more and more widespread. [0003] Water-based ink is mainly made of water as a solvent through scientific processing. Compared with other printing inks, water-based ink does not contain volatile toxic organic solvents, so it has no adverse effects on the health of printing machine operators during the printin...
