Gel pen ink for smooth writing

Abstract

The invention relates to gel pen ink for smooth writing, belonging to the technical field of ink. The gel pen ink is characterized by comprising the following raw materials by weight percent: 30-40% of water-based color paste, 10-30% of a wetting agent, 1-8% of a dispersing agent, 0.1-1% of a lubricant, 0.1-15% of a thickening agent, 0.01-0.1% of a preservative, 3-4% of a PH regulator, 30-60% of deionized water, 0.4-0.6% of an anti-rusting agent, 1-2% of a surface active agent and 0.5-1% of a defoaming agent. The gel pen ink has the beneficial effects of excellent refrigerated storage stability, smooth writing handfeel, clear lines and long dry resistance time.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to gel pen ink with smooth writing. 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 technic...
