| Abstract: | The effect of some factors for preparing wollastonite/TiO2 composite particle（WOL/Ti-CPM） by mechano-chemical method,the pigment property of WOL/Ti-CPM and its micro application in the paint were studied in this paper.The results show that the mechanical factors,such as ratio of grinding media to powder feeding and compound time,and TiO2 dosage have significant influences on the properties of WOL/Ti-CPM.WOL /Ti-CPM is similar to that of titanium dioxide,the whiteness is 96.6%,the hiding power is 17.97g/cm2,the oil adsorption is 22.72g/100g.SEM images indicates that TiO2 has been coated on surfaces of wollastonite effectively. |
