High-temperature-resistant flame-retardant iron oxide pigment

Abstract

The invention discloses high-temperature-resistant flame-retardant iron oxide pigment. The iron oxide pigment comprises 95-105 parts by weight of iron oxide red particles, 46-48 parts by weight of polyvinyl alcohol, 4-8 parts by weight of sodium dioctyl sulfosuccinate, 8-12 parts by weight of sorbitan acid ester, 7-11 parts by weight of phosphatidylcholine, 4-6 parts by weight of ethyl titanate, 28-32 parts by weight of a sodium hydroxide solution, 5-7 parts by weight of 2-methyl-4-isothiazolin-3-one, 6-10 parts by weight of sodium silicate, 41-47 parts by weight of butanediol, 72-82 parts byweight of deionized water and 4-8 parts by weight of a high-temperature-resistant flame-retardant assistant. The iron oxide pigment provided by the invention is reasonable and scientific in composition preparation, good in pigment color, high in oxidation stability, good in suspension property and low in sedimentation property, agglomeration does not occur easily, storage and transportation are facilitated, weather resistance is good, wear resistance is achieved, and meanwhile, high-temperature resistance and flame retardancy of the pigment are greatly improved, and the prepared pigment is uniform in texture, good in dispersity and high in liquidity.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a high-temperature-resistant and flame-retardant iron oxide pigment. 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 b...

Problems solved by technology

[0003] However, the performance of the currently commercially available iron oxide pigments is not very satisfactory, its dispersibility and suspension are poor, the sedimentation speed is fast, and it is easy to agglomerate, especially in the aspect of high temperature resistance and flame retardancy. Generally, the performance at 200 ° C is already unstable

Therefore, its application is limited
