Problems solved by technology

Moreover, when the paint formulation is used, often due to poor dispersion, the gloss of the paint decreases and the viscosity increases.
These have greatly increased manufacturing costs and wasted resources

Abstract

The invention relates to the field of titanium dioxide slurry and titanium dioxide preparation, in particular to a titanium dioxide composite material and a preparation method thereof. The titanium dioxide composite material is mainly prepared from a phosphine carboxylic acid compound and a titanium dioxide material with a coating layer, the phosphine carboxylic acid compound has a structure as shown in a general formula (I) or (II). The titanium dioxide composite material has excellent dispersing performance and can be quickly dispersed in water without the aid of external force; in addition, the titanium dioxide composite material also has relatively excellent heat storage stability and application performances such as hue, covering power and glossiness.

Description

technical field [0001] The invention relates to the field of preparation of titanium dioxide slurry and titanium dioxide, in particular to a titanium dioxide composite material and a preparation method thereof. Background technique [0002] When coating companies make titanium dioxide slurry, they generally use TiO 2 Titanium dioxide slurry is prepared by direct high-beating of dry powder, but the titanium dioxide slurry cannot be used up immediately, so when it is stored, in order to maintain the dispersion of the slurry, it needs to be continuously stirred. [0003] At the same time, in order to save costs and meet the demand of downstream coating companies for titanium dioxide slurry, titanium dioxide manufacturers will choose to beat the semi-finished filter cake of titanium dioxide with dispersant, and make it into titanium dioxide slurry, which will be transported to downstream enterprises by tanker . However, this titanium dioxide slurry also has the same problems, ...
