Abstract

Abstract

Aiming at the differences in the application performance of titanium dioxide at home and abroad, the morphology of different titanium dioxide products including GT1, GT2 and MT were analyzed by SEM, TEM, EDS, XPS and FTIR. The influencing factors of the glossiness of titanium dioxide in coatings were studied. The results show that the MT particle size is centrally distributed in the range of 0.1-0.5 μm, with a mean particle size of 0.249 μm. The MT surface envelope has a high degree of integrity, with the thickness of the envelope layer ranging from 1.2 to 4.5 nm. The MT surface has a high hydroxyl content, with low oil absorption and specific surface area, and good dispersion in the coating. This is because the surface structure of foreign titanium dioxide MT is better than that of GT1 and GT2, so that the gloss of MT in coatings is higher than that of domestic titanium dioxide products GT1 and GT2.
