Problems solved by technology

However, surfactants are often similar in structure to pigment dispersants in colorants and thickeners in neutral inks, such as commonly used commercial non-ionic alkylphenol polyoxyethylene ether surfactants (APEO series) And non-ionic fluorocarbon surfactants (FSO series) have a strong polar group hydroxyl group in the molecule, and the hydroxyl group will associate with the hydrogen bond between the pigment dispersant and the thickening system in the colorant, resulting in pigment dispersion and thickening Thick system is unstable

Abstract

The invention discloses a multifunctional auxiliary agent, which is prepared by removing one molecule of water from the catalytic condensation reaction between a nonionic fluorocarbon surfactant (FSO) and a nonionic alkylphenol polyoxyethylene ether surfactant (APEO). have to. By removing the strong polar group hydroxyl groups in FSO and APEO molecules, condensation builds longer chains of weakly polar hydrophilic polyoxyethylene ether segments, which not only eliminates the presence of hydroxyl groups in surfactants. The effect of the hydrogen bond association with the pigment dispersant and the thickening system has an adverse effect on the pigment dispersion and thickening system, and because the condensate can form a larger space network structure with the pigment dispersant and thickener, Further improved the stability of pigment dispersion and thickening system. The obtained condensate can be used as a multifunctional additive for neutral ink because it acts as a surface tension regulator, a lubricant and a humectant at the same time.

Description

technical field [0001] The invention belongs to the technical field of stationery, and in particular relates to a multifunctional additive for gel pen ink. Background technique [0002] Medium-viscosity gel-like water-based pigment ink, referred to as neutral ink, is a matching ink for gel pens. Gel pens are a new type of ballpoint pen products. Because of their smooth writing, clear handwriting, good color, and excellent characteristics such as water resistance, light resistance, and long shelf life, they are deeply loved by consumers at home and abroad. The market share keep improving. [0003] The preparation of neutral ink generally adopts the preparation of color paste first, and then adds rheology regulator and other functional components such as surface tension regulator, lubricant, humectant, defoamer, corrosion inhibitor (anticorrosion agent), anticorrosion and anti-mildew Agents, etc., are formulated into finished inks through a certain process. [0004] By adju...
