As a typical functional additive in the production of architectural coatings, the addition of the dispersant can make the pigments and fillers to be dispersed more completely and avoid the film defects including floatings, delamination and caking, etc. However, most of the dispersants in the market are liquid and are not suitable for the powder products such as diatom mud. In this paper, different kinds of powder dispersants are selected, and their dispersing effects on conventional organic and inorganic pigments are compared. Meanwhile, the effect of powder dispersant on the water resistance and UV resistance of diatomite mud after molded is studied. According to the test results, the type and amount of powder dispersant suitable for diatom mud products are obtained.
Key words: powder dispersant; diatom mud; pigment dispersing; water resistance; UV resistance
