Problems solved by technology

However, the method used in this application needs to dissolve yellow iron oxide in an organic solvent, and then add 0.3 to 15% of elements selected from the 3rd and/or 4th main group, such as aluminum compounds, which makes the production process extremely complicated and reduces the production cost. Greatly improve
Iron yellow pigment is a low-value pr

Abstract

The invention relate to a heavy iron oxide yellow, which comprises high density iron oxide yellow powder. The high density iron oxide yellow powder is made from the iron oxide yellow powder with a ball mill through vibratory milling or milling. The bulk density of the heavy iron oxide yellow manufactured through milling method is increased by 10-70 percent compared with that of the general iron oxide yellow, therefore, the storage and transportation space occupied by the same amount of iron oxide yellow pigment is greatly reduced, and the transportation cost is lowered. The invention also has the advantages of simple technique and low cost.

Description

(1) Technical field [0001] The invention relates to a heavy iron yellow pigment and a preparation method thereof, that is, the iron yellow pigment with relatively high bulk density. (2) Background technology [0002] Iron oxide yellow is iron oxide hydrate, there are two kinds of natural and synthetic, the color light is from lemon yellow to orange yellow to brown, the powder is fine, it is crystalline iron oxide hydrate. Usually refers to ferric oxide hydrate, chemical formula Fe2O3 H2O, English name: Iron oxide yellow, relative molecular weight 177.71 (according to the international atomic weight in 1987). Relative density 2.44-4g / cm 3 , Bulk density: 0.3~0.6g / cm 3 , melting point 350-400 ℃. Insoluble in water, alcohol, soluble in acid, not resistant to high temperature, strong in light resistance, weather resistance and resistance to dirty gas, the tinting strength is almost equal to that of lead yellow. Natural iron oxide yellow iron yellow, also known as khaki, rang...
