Problems solved by technology

The first traditional yellow color paste prepared using cadmium yellow as toner has low transparency and low chroma, and cannot meet the color requirements for high color; in addition, due to the use of cadmium yellow as toner, it is difficult to It is harmful to the health of workers and consumers. During the cleaning process, paint scrapping treatment, coating film aging and other processes, the loss of cadmium will seriously pollute water quality and soil. The country has strictly ordered the use of cadmium yellow as a yellow colorant in paint Toner, the addition of cadmium is strictly prohibited
The second type uses organically synthesized yellow dyes as coloring agents for yellow colorants. Due to the poor weather resistance of dyes, most of them are used in papermaking, ink and other industries. For industries with strict weather resistance requirements such as automotive coatings, very few The dye can meet the requirements; in addition, it is also a bottleneck in the preparation of yellow color paste in terms of manufacturing formula and process
[0004] At present, the defects of yellow color paste mainly include: first, the use of toner containing heavy metals such as lead and cadmium will cause heavy metal pollution to water and soil, and cannot meet the requirements of laws and regulations; second, the use of organically synthesized yellow dyes as coloring Color paste, complex manufacturing process, high cost, poor weather resistance, poor workability, can not meet the requirements of high-end coatings such as automobiles
