Abstract

The invention discloses a neutral ink, which comprises the following components in parts by weight: 3 to 7 parts of carbon black, 11 to 17 parts of methacrylic acid, 24 to 28 parts of deionized water, 4 to 6 parts of methyl methacrylate, 3 to 4 parts of polyacrylamide, 1 to 3 parts of sodium pyrophosphate, 2 to 6 parts of dimethyl ethanol amine, 2 to 5 parts of sodium tripolyphosphate, 2 to 4 parts of oleic acid, 1 to 3 parts of tributyl phosphate, 5 to 8 parts of sodium stearate, 1 to 2 parts of dispersant, 1 to 3 parts of thixotropy and rheology conditioning agent, and 0.5 to 1 part of mildew inhibitor. The dispersant is prepared by compounding an anionic dispersant and polyethylene glycol 200; the viscosity of the neutral ink is adjusted to a proper range by the thixotropy and rheology conditioning agent; and the viscosity stability is maintained so as to prepare a high quality neutral ink.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a neutral ink and a production process thereof, belonging to the technical field of fine chemicals. Background technique [0002] Ink is one of the necessary writing materials for people in all social activities. China's pen-making industry has been established in the early 1950s, and now it has a considerable scale, creating a relatively complete production system with multiple categories and varieties. The output and export volume of various pen products in China have ranked first in the world, and China's pen industry has become a major producer and exporter of the world's pen industry. Although China has become a big country for making pens, it is not yet a powerful country for making pens, because the technology and materials for production, especially ink and nibs, have not been fully resolved. Although many companies are developing neutral inks, the quality of do...
