High-stability gel ink and production method thereof

Abstract

The invention relates to the technical field of ink and provides high-stability gel ink and a production method thereof with an aim to provide the high-stability gel ink stable in ink system, free from precipitation and pig skin, good in storage stability and excellent in writing performance. The high-stability gel ink is prepared from, by weight, 10-40% of a humectant, 1-8% of a dispersing agent, 0.1-1% of a lubricant, 20-40% of water-based color paste, 0.5-15% of a thickener, 0.01-0.1% of a corrosion remover, 0.5-5% of PH regulator and 30-60% of deionized water; wherein the water-based color paste is prepared from, by weight, 10-40% of a water soluble dispersant, 1-8% of water-based wetting agent, 20-50% of carbon black powder, 0.1-1% of a corrosion remover, 30-70% of a deionized water and 0.01-0.1% of PH regulator.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a highly stable gel pen ink and a manufacturing method thereof. Background technique [0002] The gel pen is a popular writing tool, mainly because the gel ink used in the gel pen has both the advantages of the wetting of the oily ballpoint pen and the smoothness of the water-washed ballpoint pen. Therefore, the gel pen The quality of ink is an important criterion for evaluating the quality of gel pens. At present, most of the commercially available gel pens use imported gel pen ink, and some gel pens that use domestic gel pen ink often have problems such as clogging of the pen head and poor writing during use, and even the refill is used. Less than one-fifth of the situation where you can’t continue writing happens from time to time. An important reason for the above phenomenon is that the stability of domestic gel pen ink is not good, and it is easy to settle, causing the tip of t...

Problems solved by technology

At present, most of the commercially available gel pens use imported gel pen ink, and some gel pens that use domestic gel pen ink often have problems such as clogging of the pen head and poor writing during use, and even the refill is used. Less than one-fifth of the situation where you can’t continue writing also happens from time to time. An important reason for the above phenomenon is that the stability of the domestic gel pen ink is not good enough, it is easy to settle, causing the tip of the pen to clog, and eventually you can’t write smoothly.
