In recent years, with the stricter environmental regulations of various countries in the world, the traditional solvent-based coating is more and more challenged, and the development trend of the coating towards solvent-free, water-based and high-solid is obvious. There has been a great tendency to develop environmentally friendly coatings to replace the prior solvent-based coatings. The pigment and filler also belong to one of the coatings. The pigment and filler slurry is beneficial to environmental protection, reduces the construction viscosity and VOC discharge amount of the coating, and has lower comprehensive cost.

The pigment and filler are the components of the coating film, and have the functions of enabling the coating film to have various colors as required and providing certain hiding power and having certain influence on the performance of the coating film. The filler is also called extender pigment, and mainly plays a role in 'filling' the coating film to increase the thickness of the coating film and improve the durability, the hardness and the like of the coating film. The existence of water in the pigment and filler greatly affects the dispersion stability of the pigment and filler, usually, the pigment and filler with a polar chemical bond structure easily adsorbs water in the air, and it is often found that the original easily-dispersed pigment and filler has a fineness in a coating which hardly meets the requirement every time the air is humid, even if the fineness meets the requirement after grinding, the pigment and filler often thickens after being placed slightly, and even if a solvent and a resin are added in a paint mixing stage, the thickening phenomenon already appears, and the fundamental reason of the phenomenon is that the surface of the pigment and filler adsorbs too much water, so that not only the diffusion adsorption process to the surface of the pigment and filler is blocked, but also the interaction between the resin and the pigment and filler is greatly weakened. The pigment and filler slurry can keep the dispersion stability of the powder to a great extent.
