Composite titanium white powder

Abstract

A composite titanium pigment consists of titanium pigment 20-70 wt%, kaolin 1-2 wt%, ZnO 0.1-0.5 wt%, brightener 0.1-0.05(OB) wt% and heavy calcium carbonate. It's stable, has excellent whiteness, coloring and covering powers and better heat, light and weather resistances. It can be used as fillers in indoor and outdoor.

Description

technical field

[0001] The invention relates to a chemical filler, in particular to a white composite titanium dioxide that can be widely used in coatings, paints, inks, papermaking, plastics, rubber, building materials and the like. technical background

[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...
