Abstract

The invention relates to a water-based nano-pigment type neutral pen ink and a preparation method thereof. Thickener 10‑30%, thickener 0.1‑3%, pH regulator 0.2‑3%, defoamer 0.05‑0.5%, lubricant 0.1‑3%, rust inhibitor 0.2‑2%, preservative 0.2‑2 %, the rest is deionized water; the average particle diameter of the resin-free nano-color paste is 100-250nm. The preparation method is as follows: fully stir and mix each component evenly, and then defoam. The invention adopts the resin-free nano-color paste to make the ink have good stability, proper viscosity, uniform particle fineness, smooth writing, uniform ink output, no flowering; bright color, light fastness, strong water resistance, and long-term storage quality is stable , There will be no stratification, precipitation and deterioration. The preparation adopts a sand mill to grind, so that the particle size of the pigment particles reaches the nanometer level, and the operation is simple and the process is reasonable.

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...
