Problems solved by technology

Among them, water-based acrylic emulsion is commonly used, which has the advantages of cheap price and stable performance, but poor elasticity, resulting in poor abrasion resistance of printed textiles
Water-based polyurethane emulsion effectively solves this problem, but there are certain problems in the compatibility of ordinary water-based fluorescent pigment pastes with water-based polyurethane emulsion, which may easily lead to uneven printing colors, spots, floating colors, blooming, and even blockage of the mesh.
At the same time, due to the need to use more anionic and nonionic emulsifiers in the preparation of water-based fluorescent pigment pastes, the washability of textile printing is reduced, usually only reaching level 3, which is difficult to meet the requirements of repeated washing of textiles

preparation example Construction

[0031] The preparation method of the emulsifier for improving the compatibility of pigments comprises the following steps: raising the temperature of the monohydric alcohol to 85±2°C, then adding an organic tin catalyst and an aliphatic diisocyanate, raising the temperature to 105-110°C and keeping it warm for 2-2.5 hours , after measuring that the NCO content reaches 10-20%, the temperature is lowered to 85±2°C (for the selection of different materials, the content of NCO groups after the completion of the reaction is different, such as the reaction with tridecyl alcohol and isophorone diisocyanate , NCO reaches 10% as the end point, and at this point in the reaction, the hydroxyl group of tridecyl alcohol reacts with the NCO group of isophorone diisocyanate to reach more than 95%, which meets the requirements of the follow-up reaction), and polyethylene glycol is dropped into the heat preservation reaction After 3.5-4.5 hours, add 370-375 parts of deionized water, cool down t...

Embodiment 1

[0057] 1) Preparation of non-ionic emulsifier: heat 50 parts of tridecyl alcohol to 85°C, then add 0.001 part of dibutyltin dilaurate and 61 parts of isophorone diisocyanate, heat up to 105 and keep it warm for 2 hours to measure the NCO content After reaching 10%, lower the temperature to 85°C, put in 262 parts of polyethylene glycol 1000, add 373 parts of deionized water after 4 hours of heat preservation reaction, drop to normal temperature and discharge, and obtain a nonionic emulsifier containing polyurethane segments.

[0058] 2), preparation of aqueous phase liquid: 2 parts of sodium polyacrylate, 5 parts of sodium dodecylbenzenesulfonate, 5 parts of basic yellow 40 and 40 parts of nonionic emulsifier prepared above are dissolved in 635 parts of deionized water to obtain an aqueous phase liquid;

Embodiment 2

[0065] 1) Preparation of non-ionic emulsifier: heat 48 parts of dodecanol to 83°C, then add 0.0015 parts of dibutyltin diacetate and 60 parts of hexamethylene diisocyanate, heat up to 108°C and keep it warm for 2.5 hours. The measured NCO content reaches 15%. Afterwards, the temperature was lowered to 83° C., 260 parts of polyethylene glycol 1400 were put in, 370 parts of deionized water were added after 3.5 hours of heat preservation reaction, and the material was cooled to normal temperature to obtain a nonionic emulsifier containing polyurethane segments.

technical field [0001] The invention relates to the field of fluorescent pigments, in particular to an emulsifier capable of improving pigment compatibility, a preparation method thereof, a water-based fluorescent pigment color paste containing the emulsifier, and a preparation method thereof. Background technique [0002] Water-based fluorescent pigment paste is used in pigment printing. The commonly used film-forming resins include water-based acrylic emulsion, water-based acrylic vinyl acetate emulsion, water-based polyurethane modified acrylic emulsion and water-based polyurethane emulsion. Among them, water-based acrylic emulsion is commonly used, which has the advantages of low price and stable performance, but poor elasticity, resulting in poor abrasion resistance of printed textiles.
