METHOD OF PREPARING A WELL-DISPERSABLE MICROCRYSTALLINE TITANIUM DIOXIDE PRODUCT, THE PRODUCT, AND THE USE THEREOF

摘要

The invention relates to a method of preparing a well-dispersable, rutile-structured, microcrystalline titanium dioxide product, a product prepared by the method, and an effect paint and a lacquer provided by means of the product. In the method, the titanium dioxide starting material is first treated with a base to have an alkaline pH value, after which it is treated with an acid to have a hydrochloric acid content of 8 to 30 g/l, neutralized, processed, and calcinated. In particular, the preparation method is characterized by the use of a pretreatment chemical before the calcination stage to improve the dispersability.
