Water-based fluorescent pigment for water-based ink and manufacturing method of water-based fluorescent pigment

Abstract

The invention discloses water-based fluorescent pigment for water-based ink and a manufacturing method of the water-based fluorescent pigment. The water-based fluorescent pigment comprises an antioxidant, polyacrylic resin, ethanol, fluorescent pigment, deionized water and other auxiliaries. The water-based fluorescent pigment is prepared from the multiple raw materials according to a reasonable matching ratio. The other auxiliaries include a wetting agent, a dispersing agent and light stabilizer. The adopted carrier resin in the water-based fluorescent pigment is the polyacrylic resin which is high in tinting strength, environmentally friendly and high in compatibility with water. The water-based fluorescent pigment for the water-based ink has the advantages of being environmentally friendly, sunproof, good in heat resisting performance, high in covering power, bright and pure in color, high in tinting strength, stability and compatibility with water-based ink and the like.

Description

technical field [0001] The invention relates to the field of fluorescent pigments, in particular to a water-based fluorescent pigment used in water-based inks. Background technique [0002] Fluorescent pigments are divided into inorganic fluorescent pigments and organic fluorescent pigments in terms of chemical composition. In terms of performance, inorganic pigments have good light and heat resistance and strong hiding power, but the color spectrum is not very complete, the coloring power is low, the color brightness is poor, and some metal salts and oxides are more toxic. Organic pigments have diverse structures, complete chromatograms, bright and pure colors, and strong tinting power, but they have poor light resistance, weather resistance and chemical stability, and are relatively expensive. The organic pigment carriers used are not environmentally friendly. Therefore, we are eager to invent a fluorescent pigment with good performance and environmental protection. The m...

Problems solved by technology

In terms of performance, inorganic pigments have good light fastness, heat resistance, and strong hiding power, but the color spectrum is not very complete, the tinting power is low, the color brightness is poor, and some metal salts and oxides are more toxic.

Organic pigments have various structures, complete chromatograms, bright and pure colors, and strong tinting power, but their light resistance, weather resistance and chemical stability are poor, the price is relatively expensive, and the organic pigment carriers used are not environmentally friendly.
