Problems solved by technology

However, the formula of dye-based ink usually contains some chemical substances that are harmful to the human body, and most of the pigments are not sufficiently colored. When stored for a long time or exposed to water and a slightly higher temperature, the ink is easy to bleed and fade, which is not conducive to the manuscript. preservation

Abstract

The invention relates to an anti-fading high-temperature-resisting water-borne black ink, wherein the ink is prepared from black pigment, anionic waterborne polyurethane-acrylate composite emulsion, carboxymethyl chitosan, polyacrylamide, sodium polyacrylate, chondroitin sulfate, lecithin, ultra-fine aluminium silicate, heavy calcium powder, nano-tin, nano-silica, and de-ionized water. The water-borne black ink improves the ink coloring and color-retention performance; the stability is good; sediment and layered agglomeration cannot appear after long-time storage; the ink is smooth and durable in writing, stable in performance and cannot block a pen point. The ink has very good high temperature resistance, and can prevent ink fading, and prolong the handwriting storage time; the raw material is toxic-free and harmless, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of ink, and relates to an anti-fading and high-temperature-resistant water-based black ink. Background technique [0002] Ink is a liquid that contains pigments or dyes and is used for writing or drawing. Black ink includes carbon ink and dye ink. At present, carbon black ink is more commonly used, which has the advantages of not easy to fade, not afraid of water, corrosion, etc. Since carbon ink uses carbon particles as the raw material for coloring, in order to make the carbon evenly distributed, colloid is used as a solvent, which has high viscosity. And the particles inside are thick, easy to block the pen, and the writing is not smooth, and it is easy to dry up and block the pen if it is written intermittently. The solute of the dye black ink is a chemical pigment molecule, and the pigment molecule is used as a colorant, which has strong fluidity, is not easy to block the pen, and does not hurt the pe...
