Abstract

The invention relates to a water-based nano pigment-type gel pen ink and a preparation method thereof. The water-based nano pigment-type gel pen ink comprises the following components in percentage by weight: 20-40% of resin-free nano color paste, 10-30% of humectant, 0.1-3% of thickener, 0.2-3% of pH regulator, 0.05-0.5% of defoaming agent, 0.1-3% of lubricant, 0.2-2% of rust inhibitor, 0.2-2% of preservative and the balance of deionized water. The average particle size of the resin-free nano color paste is 100-250nm. The preparation method comprises the following steps: sufficiently stirring and uniformly mixing the components, and defoaming. By using the resin-free nano color paste, the ink has the advantages of favorable stability, proper viscosity, uniform particle fineness, smooth writing and uniform ink release without floating. The ink has the characteristics of bright color, light fastness, high water resistance and high stable quality after long-term storage, and can not have the phenomenon of stratification, precipitating deterioration or the like. The sand mill is used for grinding, so that the particle size of the pigment particles reaches nano scale. The preparation method is simple to operate and reasonable in technique.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a water-based nano-pigment type gel pen ink and a preparation method thereof. Background technique [0002] Neutral ink has the advantages of smooth writing, comfortable writing, clear writing, good color, and writing resistance to water, sunlight, and long storage time. It has been quickly accepted by consumers, and its market share has surpassed oil-based ballpoint pens. The growth trend, although my country has become the largest producer of gel ink pens, so far almost all the ink used in gel ink pens is imported, mainly from Japan, the United States, Germany and South Korea. [0003] Judging the comprehensive performance of neutral ink is rheological performance and stability. Rheological properties are not only related to factors such as the type of thickener, solvent, solution concentration, electrolyte strength, pH value, temperature, etc., but also related to the...
