Abstract

In order to solve the stability problem of the existing neutral ink, the invention discloses high-stability neutral ink. The high-stability neutral ink comprises the following components in percentage by weight: 0.1%-0.2% of nonylphenol polyoxyethylene ether, 0.0.3%-0.05% of fluorocarbon surfactant, 50%-70% of mill base with 4%-6% of water-soluble pigment, 10%-15% of thickening agent, 5%-20% of moisture-retention lubricant and 0.05%-0.1% of antiseptic antimildew agent. According to the high-stability neutral ink, a plurality of surfactants are used in a matched manner, so that the proportion of materials is optimized, and therefore, the prepared neutral ink is high in stability and capable of greatly improving the writing performance.

Description

technical field [0001] The invention relates to a neutral ink, in particular to a highly stable neutral ink. Background technique [0002] Gel pens are loved by consumers at home and abroad because of their smooth writing, clear handwriting, and the advantages of water resistance, light resistance and long shelf life. Neutral ink is the abbreviation of medium-viscosity gel-like water-based pigment ink. Neutral ink is a thermodynamically unstable system. Due to its many components, some components such as pigment carbon black and some thickeners that adjust ink viscosity and rheology are insoluble in water and are suspended and dispersed in the ink system in the form of particles. At the same time, the interaction between the various components is also very complicated. Therefore, solving the stability of the neutral ink is the key technology for its development. [0003] Such as CN02104934.3, the invention patent titled "a kind of neutral ink", discloses a kind of neutral ...
