Abstract

The invention relates to waterproof ink for a gel-ink pen and belongs to the technical field of ink. The waterproof ink for the gel-ink pen is prepared from the following materials in parts by weight: 20-35 parts of carbon black, 5-15 parts of amphiphilic carbon material, 3-14 parts of surfactant, 10-16 parts of glycerol, 5-9 parts of phenoxy ethanol, 2-9 parts of pentaerythritol ester, 5-14 parts of triethanolamine, 1-6 parts of sodium benzoate and 40-58 parts of deionized water. According to the waterproof ink for the gel-ink pen, the problem of poor hydrolytic resistance of the ink in the prior art is solved since the carbon black and the amphiphilic carbon material are used as coloring agents together; stable performance is ensured; the permeability is also improved; the waterproof ink has water resistance; and the ink does not fade, deteriorate or decay when wetted with water.

Description

technical field [0001] The invention relates to an ink for a writing instrument, more specifically, the invention relates to a water-resistant ink for gel pens, which belongs to the technical field of ink. Background technique [0002] A ball-point pen with a writing medium whose viscosity is between water and oil is called a gel pen; the gel pen originated in Japan and is a novel writing tool that is currently popular in the world. Gel pens have the advantages of both fountain pens and ballpoint pens, with comfortable writing, low ink viscosity, and added substances that are easy to lubricate, so they are smoother than ordinary oily ballpoint pens, and are an upgraded product of oily ballpoint pens. [0003] Although gel pens are all ballpoint pen products, their writing principle and structure of the nib are similar to those of traditional oil-based ballpoint pens, but there are special requirements for the nib due to the difference in the performance of the ink used.
