Surface Treatment Of Titanium Dioxide And Its Application In Master Batch

Titanium dioxide is widely used in master batch as inorganic pigments, and the size of the particle is valued by micron. The finer pigments must be surface treated before used for its tendency to agglomerate. The surface treatment of titanium dioxide by coupling agent and surfactant was studied in this paper. The surface functional group and property were changed for improving the dispersebility of titanium dioxide. The modified titanium dioxide was used for the manufacture of white color master batch. The influence of surface treatment to performance master batch was studied.The result showed that the TiO₂ surface was changed after coating, and the property of surface variated from hydrophile to hydrophobic. The result is better when the content of the amount of coupling agent A was 2 wt % and coupling agent B was 3 wt % for inorganic coated titanium dioxide. The property of modified titanium dioxide was studied through TG, TEM and so on. The result showed that the dispersibility was excellent, and the particles...
