Metal-oxide mixed-phase titanium-chromium brown pigment and preparation process thereof

Abstract

The invention relates to a chemical raw material and a preparation process thereof, in particular to a metal-oxide mixed-phase titanium-chromium brown pigment and a preparation process thereof. The metal-oxide mixed-phase titanium-chromium brown pigment comprises the components of titanium dioxide, dichromium trioxide, diantimony trioxide, lithium fluoride, sodium tetraborate, potassium carbonate, rare earth oxide, cerium oxide and rubidium oxide. According to the metal-oxide mixed-phase titanium-chromium brown pigment and the preparation process thereof disclosed by the invention, a dispersing agent and a color fixing agent suitable for a metal-oxide mixed-phase pigment product are used, and the added quantity and the adding condition of an auxiliary agent are carefully chosen, so that the aim of complete pigment transition and uniform color and luster is fulfilled, the high-temperature transition of the product is effectively controlled, the problem of particle aggregation is solved, the aim of energy saving and consumption reduction is fulfilled, the production cost is reduced, and the equipment utilization ratio is effectively increased.

Description

technical field [0001] The invention relates to chemical raw materials and a preparation process thereof, in particular to a metal oxide mixed-phase titanium chrome brown pigment and a preparation process thereof. Background technique [0002] Metal Oxide Mixed Phase Pigment (abbreviated as MMO) is a new type of environmentally friendly high-performance chemical raw material with wide uses. Its product features are: bright color, easy to disperse, good hiding power, excellent light resistance, weather resistance, thermal stability, Chemical stability, no bleeding and migration, compatible with most thermoplastic and thermosetting resins, is an internationally recognized non-toxic, environmentally friendly pigment, whether organic or inorganic, does not have the above comprehensive functions, Such pigments are suitable for high-performance requirements such as modern coatings and plastics. [0003] Metal oxide mixed-phase titanium chrome brown pigment has a wide chromatograp...

AI Technical Summary

Problems solved by technology

[0004] The metal oxide mixed-phase titanium chrome brown pigment market is widely used and is closely related to the development of the national economy. However, my country's metal oxide mixed-phase titanium chrome brown pigment industry has just started, and more than 90% of the annual demand of about 5,000 tons depends on Europe, America, Japan, etc. Imported from developed countries, foreign products are expensive and often out of stock, and the quality is unstable
