Environment-friendly high-concentration neutral ink color paste and preparation method thereof

Abstract

The invention discloses an environment-friendly high-concentration neutral ink color paste in the technical field of neutral ink color pastes. The environment-friendly high-concentration neutral ink color paste is characterized by comprising the following ingredients by percentage: 5-25wt% of dye, 5-15wt% of film former, 30-60wt% of solvent, 5-20% of dispersing agent, 2-10wt% of other assistant, 1-5wt% of strong electrolytic inorganic salt, and 1-15wt% of noble metal nano particle. A preparation method comprises the following steps of putting 50 parts by weight of hot water above 80 DEG C in apreparation container, directly adding 10% of black dye and 5% of acid red dye into 50 parts by weight of water during stirring, performing stirring after complete dissolution and cooling, sequentially adding 8% of film former, 50% of solvent, 13% of dispersing agent, 2% of strong electrolytic inorganic salt and 12% of noble metal nano particle into the container in a stirring process, continuously stirring for 40min, standing for 7 days, and performing filtration.

Description

technical field [0001] The invention relates to the technical field of neutral ink color paste, in particular to an environment-friendly high-concentration neutral ink color paste and a preparation method thereof. Background technique [0002] Neutral ink is mainly composed of three main components: dye paste, solvent, and additives. It is generally used in office book writing, printing and other fields. There are many problems in the use of existing inks, and inks are usually due to the configuration materials. Determine the quality of the ink. When the existing ink is in use, some ink needs to be oxidized with air for a long time to show the color when it is printed or written on paper. It is extremely inconvenient for some workers, and the ink Generally, the concentration of the ink will be uneven, which will make the color of the ink uneven after use, which will affect the quality of printing. In the process, it seeps into areas that should not be reached, resulting in ...

There are many problems in the use of existing inks, and inks are usually due to the configuration materials. Determine the quality of the ink. When the existing ink is in use, some ink needs to be oxidized with air for a long time to show the color when it is printed or written on paper. It is extremely inconvenient for some workers, and the ink Generally, the concentration of the ink will be uneven, which will make the color of the ink uneven after use, which will affect the quality of printing. In the process, it seeps into areas that should not be reached, resulting in waste of paper, waste of resources and pollution of the environment, and different materials need to be replaced with different inks for printing, which is troublesome
