Description
Technical field
The invention belongs to chemical fields, and in particular to a method of produce ultralow hydrotrope iron oxide pigment.
Background technique
In pigment manufacturing process, it is impossible to the component complete synthesis of all raw materials in the chemical constituent of pigment, but
It generates a certain amount of insoluble impurity to be mixed into pigment finished product, and generates a certain amount of soluble impurity simultaneously.It is conventionally produced
Ferric oxide red colorant out can contain more impurity, be difficult to apply to high-end field, any impurity is brought into all
Very big difficulty and problems can be brought to subsequent production, so be both to waste social resources while also consuming manpower
With material resources.Therefore, demand of the high-end manufacturer to ultrapure ferric oxide red colorant using ferric oxide red colorant as raw material is compeled very much
It cuts.Since retaining for the hydrotrope can make film and contact with moisture, hole is formed, protective effect of the paint film to ground is destroyed, and
And these salinities can also cause the corrosion of ground.The iron oxide red of low pH value is reduced to its dispersibility in the application is reduced
Properties of product.
Conventional oxidation iron pigment is mainly completed by aoxidizing twice, is formd after secondary oxidation and is existed comprising iron oxide
Interior more substance wet feeds, the specific steps are as follows:
Once oxidation: ferrous nitrate prepares 4Fe+10HNO3 → 4Fe(NO3)2 + NH4NO3 + 3H2O
Ferrous sulfate prepares H2SO4+Fe→FeSO4+H2↑
Secondary oxidation: 44Fe+4Fe (NO3)2 +4FeSO4+ 4NH4NO3+ 5O2+ 40H2O→ 26Fe 2O3 +4(NH4)2SO4+
8NO+32H2↑。
Traditional rinsing process is repeatedly rinsed using water, can reduce the hydrotrope to a certain degree, but data are much not achieved
The data of world-class level.And the content of the hydrotrope can not be reduced again after rinsing to a certain extent, or even can bring into new
Impurity, meanwhile, certain hydrotropes can largely be present in product because the reason of rinse water temperature dissolve seldom
In, it is provided in national standard, the hydrotrope is qualification lower than 0.5%, and existing market default is qualification lower than 0.3%, but a part of
User needs to approve lower than 0.15%, so needing new technique.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide production ultralow hydrotrope iron oxide
The method of pigment.
Technical solution: in order to achieve the above object of the invention, what the present invention was specifically performed by: a kind of ultralow water of production
The method of molten object iron oxide pigment, comprising the following steps:
(1) raw material progress two-step oxidation is obtained into slurry formula semi-finished product, by semi-finished product by obtaining wet feed after filter screen, and will be wet
Material is passed through washing stirred tank, is kept stirring 10 ~ 20r/min of rate；
(2) deionized water being imported into water tank, and water tank is heated, temperature is controlled at 60 DEG C,
(3) deionized water after heating in water tank is squeezed into washing stirred tank with pump to rinse wet feed, is kept stirring speed
Rate；
(4) hydrotrope in wet feed is detected, is to pass lower than 0.15%.
Wherein, steam heating method is used to water tank in the step (2).
Wherein, the filter screen fineness is not more than 200 mesh.
The utility model has the advantages that the present invention compared with traditional technology, uses 60 DEG C of deionized water as rinsing liquid, product can be allowed
Hydrotrope data reach world-class level, the hydrotrope can be reduced to 0.15% hereinafter, even lower than 0.1%, global same
It can be at clear ahead level in industry wide.
