Abstract

The invention aims at solving a writing performance problem of existing gel inks, and provides a gel ink with good writing performance. The ink comprises the components of, by weight, 0.042-0.043% of acetylene-modified polysiloxane emulsion, 2-3% of a thickening agent, 30-50% of a color paste containing 4-6% of a water-soluble pigment, 10-15% of a surfactant, 5-20% of a moisturizing lubricant, 0.05-0.1% of a preservative fungicide, 0.2-0.8% of a pH value adjusting agent, and 30-40% of deionized water. According to the invention, the acetylene-modified polysiloxane emulsion is adopted as a defoaming agent, and the ratio of the materials is optimized, such that the writing performance of the prepared gel ink is greatly improved.

Description

technical field [0001] The invention relates to a neutral ink, in particular to a neutral ink with good writing performance. 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. Generally, the surface tension of the writing substrate is 35-40 mN / m. Only when the surface tension of the neutral ink is lower than that of the writing substrate can an effective coverage without spots be formed on the writing substrate. Therefore, the surface tension of neutral ink is generally controlled at 25-30mN / m. The low surface tension of neutral ink systems causes the system to be prone to foaming. The introduction of air bubbles will seriously affect the writing performance of the ink. [0003] Such as CN02104934.3, the invention patent titled "a kind of neutral ink", discloses a kind of neutral ink, which is to add 10-15% thicken...
