Study on Dispersion and Performance of Yellow Lake


Article Preview

In order to study the dispersion and performance of tartrazine aluminum lake, 7 kinds of water-based resins are used to form disperse system. These systems are enviroment friendly (low VOC) and use edible yellow lake as colorant. If proper adjustment is added, these disperse systems can be made into ink and paint. The application field should be printing or coating on all the food or drug packages, toys and decorate materials, which will improve social safe level. Colorant, resin, wetting agent, co-solvent, emulsifier, and deionized water are mixed at certain ratio and pre-dispersed for 15min, then dispersed in GJ-2S high speed sanding mill for 3h. Size distribution, PDI, color characteristics (reflectance spectroscopy and color density), glossiness, abrasion performance, and stability are studied. Results demonstrate particle size of disperse system is 338.1~595.3nm (PDI<0.3) and changed to 428.6~551.2nm after 5 days or so. Reflectance spectroscopy is close to PANTONE standard yellow. Glossiness is referred as Gs(60°)≥32°. Viscosity is 0.2~2Pa·S. Relative stable disperse system is prepared.
