Problems solved by technology
[0002] Titanium dioxide (TiO2) and lithopone (ZnS.BaSO4) are fine white powders with good tinting power and hiding power, and are widely used in coatings, paints, inks, papermaking, plastics, rubber, building materials and other products application, but the product has to overcome the environmental pollution caused by many raw materials in the production process, such as: lithopone, titanium dioxide production process to the sewage treatment problem, so the current market price of titanium dioxide and lithopone is relatively high
In order to reduce costs, although there are lithopone or composite titanium dioxide compounded with other substances in the prior art, the use effect is often much worse than that of titanium dioxide or lithopone. For example, in the batching of composite titanium dioxide disclosed in CN1052127 A large amount of wollastonite is added. Due to the high impurity ratio of wollastonite, the whiteness of the obtained product is not enough, the covering property is poor, and it will turn black under acidic conditions
