Abstract

The invention provides silver neutral ink with high stability to fill up a gap of the sliver neutral ink. The silver neutral ink comprises the following components in percentage by weight: 0.2-0.3% of xanthan gum, 1-2% of alkali-swellable acrylic acid, 30-50% of water-soluble aluminum silver paste, 10-15% of surfactant, 5-20% of moisturizing and lubricating agent, 0.05-0.1% of antiseptic antimildew agent, 0.2-0.8% of pH value regulating agent and 30-40% of deionized water. The prepared silver neutral ink disclosed by the invention has good rheology and can greatly improve the writing performance.

Description

technical field [0001] The invention relates to a neutral ink, in particular to a silver 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. Silver neutral ink is made by compounding pigments, water, solvents, thickeners and additives. The preparation process of neutral ink is roughly divided into two steps: the first is the dispersion of pigments, that is, the preparation of pigment paste; the second is the preparation of ink. Among them, uniformly dispersing pigments that are neither water-soluble nor solvent-soluble in water and solvents to make pigment pastes with good stability and high concentration is a key link in the preparation of high-quality neutral inks. [0003] Such as 200710070334.6, the invention paten...
