Abstract

The invention discloses quick-drying carbon ink and a preparation method thereof. The ink comprises the following raw materials in percentage by weight: 3-4 percent of a dispersing agent, 23-30 percent of carbon black, 8-12 percent of amphiphilic carbon materials, 0.05-1 percent of methyl silicone oil, 1-2 percent of gelatin, 0.05-0.15 percent of triethylamine, 10-15 percent of alkali-swelling acrylic acid, 0.03-0.08 percent of polyvinyl alcohol, 0.05-0.1 percent of sodium benzoate, 0.01-0.02 percent of nano titanium dioxide, 0.02-0.04 percent of nano-zinc oxide, 8-15 percent of alcohol and 30-40 percent of water. The preparation method comprises the steps: preprocessing carbon black and amphiphilic carbon materials; mixing methyl silicone oil, gelatin, triethylamine, polyvinyl alcohol, sodium benzoate, nano titanium dioxide and nano-zinc oxide with water; adding alkali-swelling acrylic acid; adding the dispersing agent, carbon black and amphiphilic carbon materials; dispersing; centrifuging, adding alcohol, dispersing, and defoaming to obtain the quick-drying carbon ink.

Description

technical field [0001] The invention relates to the field of office technology, in particular to a fast-drying carbon ink and a preparation method thereof. Background technique [0002] Carbon ink is a kind of black ink. The main component of carbon ink is carbon. Since carbon is chemically stable at normal temperature and pressure, it is not easy to react with other substances, so the text written in carbon ink is easy to save. Not easy to fade. However, in the process of using carbon ink, there is a big problem: due to the long condensation time, it is very easy to cause contamination of body clothes and hands, especially the smear of the previous handwriting, resulting in blurred information, which is difficult to print. identify. Therefore, it is of great significance to study a kind of fast-drying carbon ink. Contents of the invention [0003] The object of the present invention is to provide a fast-drying carbon ink with good coloring strength, permeability, water...
