Iron oxide pigment with good dispersity

Abstract

The invention discloses iron oxide pigment with good dispersity. The iron oxide pigment comprises the following components: 100 parts by weight of iron oxide pigment, 12 parts by weight of modified graphene, 8-10 parts by weight of a polyurethane thickener, 2-6 parts by weight of ethyl titanate, 1-3 parts by weight of sodium peroxide powder, 2-4 parts by weight of nano silicon dioxide powder, 2-4parts by weight of sodium dioctyl sulfosuccinate, 1-3 parts by weight of polyaluminium chloride, 3-5 parts by weight of hydroxypropyl methyl cellulose and the like. The iron oxide pigment provided bythe invention is reasonable and scientific in composition preparation, dispersion performance of the components is effectively improved, dispersity of the prepared iron oxide pigment is greatly improved, dispersity is good, and liquidity is high. Meanwhile, the added other components are mostly components which have small particle diameters and are easy to disperse, so that dispersion performanceof the iron oxide pigment is further increased. The iron oxide pigment further has the characteristics of high chroma, high oxidation stability, good weather resistance, small flow hue change, high-temperature resistance and the like, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to an iron oxide pigment with good dispersibility. Background technique [0002] Iron oxide pigments are the most widely used pigments in the paint industry, and they are also the main inorganic coloring materials in the color-matching integrated system of paint production lines. Iron oxide pigments mainly refer to iron oxide red, iron yellow, iron black and iron brown four types of coloring pigments based on iron oxides, among which iron oxide red is the main one (accounting for about 50% of iron oxide pigments) , Mica iron oxide used as an anti-rust pigment and magnetic iron oxide used as a magnetic recording material also belong to the category of iron oxide pigments. Iron oxide is the second largest inorganic pigment after titanium white, and also the largest color inorganic pigment. Among all the iron oxide pigments consumed, more than 70% are prepared by chemical synthesis,...
