Abstract

The invention discloses a composite titanium dioxide and a processing method thereof. The composite titanium dioxide comprises, by weight, 6-10 parts of barite, 8-12 parts of light calcium carbonate, 3-15 parts of sodium silicate, 2-5 parts of a whitening agent TA, 3-4 parts of PGFE, 0.2-1.2 parts of cerium sulfide, and the balance titanium dioxide. Common titanium dioxide can be adopted to realize the performances of high-quality titanium dioxide, so the cost is substantially reduced.

Description

technical field [0001] The invention relates to titanium dioxide, in particular to a composite titanium dioxide and a processing method thereof. Background technique [0002] Titanium dioxide is an inert pigment and is considered to be the best white pigment in the world. Titanium dioxide has stable physical and chemical properties, excellent optical and electrical properties and excellent pigment performance, so it is widely used in coatings, plastics, papermaking, chemical fibers, inks, rubber, electronics, cosmetics, welding electrodes, enamel Titanium dioxide is used in ceramics, metallurgy, etc. Especially the pigment titanium dioxide, because of its incomparable various excellent properties of other white pigments, so that after its appearance, it soon replaced the traditional white pigments such as lead white, zinc white, lithopone and other white pigments, and became a white pigment. s King. [0003] However, the current production technology of titani...
