Abstract
The invention relates to superfine water-based pigment ink and a manufacturing method thereof. The superfine water-based pigment ink is suitable for high-requirement pens for writing and printers and comprises the following components in weight percent: 1% to 10% of pigment, 5% to 10% of water-based resin, 0.1% to 2% of wetting agent, 0.1% to 2% of dispersant, 0.1% to 2% of foam killer, 10% to 50% of resolvent and 30% to 70% of water, wherein as different kinds of pigment can be used, the particle diameter of the pigment ranges from 40 nm to 80 nm. The manufacturing technique comprises the steps of shearing and dispersing, high-pressure collision, multi-stage sanding and ink compounding. The ink provided by the invention flows out smoothly and is high in storage stability; a manufactured writing pen can be still used normally after being transported at high temperature for a long time.
Description
technical field [0001] The invention relates to a pigment ink, in particular to an ultrafine water-based pigment ink and a manufacturing method thereof. Background technique [0002] Water-based inks are divided into water-based dye inks and water-based pigment inks according to their color properties. The advantage of the dye-based ink is that the dye is dissolved in water, and the ink of the writing pen is smooth, easy to manufacture, and low in cost. The disadvantage is that the ink is not water-resistant and light-resistant. For pigment-based inks, the pigments are highly dispersed in the medium, which overcomes the characteristics of dye-based inks that are not resistant to water and light. However, mechanical sanding of the pigments is required during manufacture, and the manufacturing process requires high requirements. Ordinary water-based pigment inks have large particle sizes and low stability, and are prone to precipitation and particle aggregation and flocculati...
