High-stability gel ink

Abstract

The invention relates to a high-stability neutral pen ink, which belongs to the technical field of ink, and is characterized in that it is made of the following raw materials in parts by weight: water-based color paste 30-40%, moisturizing agent 10-30%, dispersant 1 ‑8%, lubricant 0.1‑1%, thickener 0.5‑15%, preservative 0.01‑0.1%, PH regulator 3‑4%, deionized water 30‑60%, rust inhibitor 0.4‑0.6%, Surfactant 1‑2%, essential oil 2‑5%, defoamer 0.5‑1%. The beneficial effects of the present invention are: the ink provided by the present invention has excellent freeze-resistant storage stability, and the writing feels smooth, the lines are clear, and the cap removal time is long.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a high-stability gel pen ink. Background technique [0002] The gel pen is a commonly used writing tool. At present, most of the commercially available gel pens use imported gel ink that can prevent freezing, and some gel pens that use domestic gel ink that can prevent freezing are used during use. On the other hand, there will often be problems such as clogging of the pen head and poor writing, and even the situation that the pen core cannot be continued to write when less than one-fifth of the pen core is used up. An important reason for the above phenomenon is that the domestic antifreeze The ink used for gel pens has poor freeze-resistant storage stability and is prone to sedimentation, causing clogging of the pen head and ultimately making it impossible to write smoothly. Contents of the invention [0003] In order to solve the above-mentioned technical problems, a technical ...
