Problems solved by technology

However, limited by the resources of titanium dioxide itself, the resources of titanium dioxide are becoming increasingly tight, and the price is high, and the production cost is relatively high.
[0003] In order to solve the high cost, lithopone, wrought white powder and other products are used to replace titanium dioxide on the market, but the comprehensive performance is far inferior to titanium dioxide, and there are problems such as poor dispersion in water-based coatings, narrow application range, poor hiding ability, and whiteness. Disadvantages of low degree

Abstract

The invention relates to composite titanium dioxide and a preparation process thereof. The composite titanium dioxide is prepared from the following compositions of 40-60 parts by weight of inorganic powders, 40-60 parts by weight of titanium dioxide, 0.2-0.5 parts by weight of stearate and 0.2-0.5 parts by weight of hydrogen containing silicone oil by a series of processes of activating, feeding and forming. According to the composite titanium dioxide and the preparation process thereof, the using amount of the titanium dioxide is extremely low, the oleophylic and hydrophilic stearate and the hydrogen containing silicone oil are adopted for modifying and cladding the inorganic powders, the composite titanium dioxide can be used for not only solvent based coating but also water-based paint and emulsion paint to replace titanium dioxide, the titanium dioxide resources are saved, and the cost of coating manufacturers is lowered, so that the composite titanium diode has the advantages that the whiteness is high, the application range is wide, the covering capability is strong, the using amount of the titanium dioxide powder is low and the production cost is low.

Description

technical field [0001] The invention relates to a composite titanium dioxide, in particular to a composite titanium dioxide with high whiteness, wide application range, low consumption of titanium dioxide and low production cost and a preparation process thereof. Background technique [0002] The scientific name of titanium dioxide is titanium dioxide, which is an inert pigment. It is considered to be a white pigment with the best performance in the world. It is widely used in coatings, plastics, papermaking, printing ink, chemical fiber, rubber, cosmetics and other industries. Especially the paint industry is the largest user of titanium dioxide. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting strength, low consumption, and many varieties. It can protect the stability of the medium and strengthen the paint film. Excellent mechanical strength and adhesion, prevent cracks, prevent ultraviolet rays and moisture from penetrating, and prol...
