Traditional pigments are usually supplied to users in the form of fine powder, which has the advantages of strong versatility, good stability, and convenient transportation; the disadvantage is that they cannot be used directly alone, and often need to be added with dispersants, wetting agents, etc. for strong mechanical grinding. There is a lot of dust during use, polluting the environment, and inconvenient color matching. In addition to the development of high-performance pigments, how to improve the application performance of existing products, increase the use value, and expand the application range is also very necessary.
At present, human beings are paying more and more attention to the environment, and the pollution of "three wastes " is the concern of all paint manufacturers. The use of water slurry pigments (color paste) and other non-powder pigment preparations (such as various pigment dispersions, masterbatches, color backs, dispersible pigments, etc.) can effectively solve the pollution of dust and sewage. It is easy to use and easy to match colors; it saves the energy-intensive and time-consuming dispersing and grinding process ; improves the application performance of pigments (such as improving color development, effectively preventing color floating and blooming, etc.), and improves work efficiency. Therefore, new preparations of pigments are one of the main directions for the development of pigment varieties. However, the versatility is limited to a certain extent, and the specialization is becoming stronger and stronger. Various formulations of pigment preparations have appeared (such as paint color paste, leather color back, plastic color masterbatch, pigment printing paste, ink color paste and industrial color paste, etc.) .
Paint color paste refers to a colorant used for color mixing of paint, which is a kind of pigment preparation. Pass the powder pigment, solvent (water or organic solvent), resin, pigment dispersant and various functional stabilizers through the strength machine
