Description

Component blending device for preparing high-performance water-based coated titanium dioxide Technical Field The utility model relates to the technical field of preparation of coated titanium dioxide, in particular to a component blending device for preparing high-performance water-based coated titanium dioxide. Background The coated titanium dioxide is a titanium dioxide product treated by a special process, and one or more layers of inorganic oxides (such as oxides of silicon, aluminum, zirconium and the like) are coated on the surface of the common titanium dioxide so as to improve the performance and expand the application field. The preparation of the coated titanium dioxide is based on a surface modification technology, and one or more layers of inorganic oxides are uniformly coated on the surface of titanium dioxide particles by using a physical or chemical method. The coating layer can change the surface properties of the titanium dioxide, such as improving the dispersibility, weather resistance, chemical corrosion resistance and the like, and can adjust the optical properties, such as refractive index, hiding power and the like. Adding titanium dioxide into a proper amount of water, adding a dispersing agent, and fully dispersing titanium dioxide particles in the water by high-speed stirring or sanding to form a stable suspension. The type and the amount of the dispersing agent can influence the dispersing effect of the titanium pigment, and common dispersing agents are sodium hexametaphosphate, sodium polyacrylate and the like. The coating agent solution was slowly added to the titanium dioxide suspension while stirring was continued. Under the condition of a certain temperature and pH value, metal ions in the coating agent can undergo hydrolysis reaction to generate hydroxide or oxide precipitate, and the hydroxide or oxide precipitate is deposited on the surface of titanium dioxide particles to form a coating layer. The mixing and stirring mode of the coating agent solution and the titanium dioxide suspension is different from that of a common reaction kettle, the common reaction kettle is started by a driving structure to quickly stir and mix the stirring piece, and the coating agent solution and the titanium dioxide suspension are mixed to realize collision and mixing among liquids, so that the coating effect is better.
