Abstract

The invention discloses composite titanium dioxide and a preparation method thereof, and belongs to the field of composite titanium dioxide. The composite titanium dioxide is prepared from the following raw materials in parts by weight: 80-90 parts of a mineral powder, 60-70 parts of 1000-2000-mesh TiO2, 4-6 parts of an activating agent, 0.5-1 part of a whitening agent, 5-6 parts of an ionic complexing agent, 5-6 parts of sodium silicate, 80-90 parts of calcium carbonate, 80-90 parts of talcum and 80-90 parts of dolomite. The preparation method combines the advantages of a dry process and a wet process, and at different stages of the preparation process, the activating agent, the super dispersing agent, the ionic complexing agent and other components which facilitate full and rapid reaction of various materials are used, so that the performance of the composite titanium dioxide is greatly improved.

Description

technical field

[0001] The invention relates to composite titanium dioxide, in particular to a composite titanium dioxide and a manufacturing method thereof. Background technique

[0002] The so-called titanium dioxide substitute refers to an inorganic powder material that has the performance of titanium dioxide and is more cost-effective than titanium dioxide, and can partially or completely replace titanium dioxide. Since the 1970s, research and development of titanium dioxide substitutes have begun, and have achieved good economic benefits. For example, Japan uses composite SiO2 titanium dioxide for synthetic fibers; the talc composite titanium dioxide produced by the United Kingdom and Germany has been used in papermaking; the United States uses mica, kaolin and TiO2 to prepare composite titanium dioxide products, which are widely used in the cosmetics industry. Composite titanium dioxide obtained by choosing some mineral powders with white powder appearance and soft te...
