Abstract

The industrial importance of calcium carbonate as a filler in composite materials such as plastics, textiles, rubbers, paints, pigments and paper is well recognized and the application in the polymer industry is increasing. Therefore, surface modification is a key process in functional calcium carbonate powder preperation. In this study, surface modification of calcium carbonate particles, obtained NiДџde region, using sodium stearate (SDS) and sodium oleate (SO) as modification agents incorporated with the simultaneous wet ultra-fine grinding in the laboratory horizontal stirred mill was investigated. The results indicate that the hydrophilic surface of calcium carbonate is turned into hydrophobic after modification with the reagents.
