Abstract

The present invention relates to a method for producing oxidized iron oxide black, which comprises the following contents: preparing a ferrite watery solution; using sodium hydroxide as a neutralizing agent for reacting with a ferrite watery solution to produce hydroxide ferrous; using oxygenous gas as an oxidant for reacting with the hydroxide ferrous to produce iron oxide black; sieving, filtering, washing, drying and pulverizing the prepared iron oxide black to obtain a blue oxidized iron oxide black pigment product. The oxidized iron oxide black produced by the method has the advantages of high purity and thin crystal grain, the grain size of produced pigment particles is thin and uniform, and the produced pigment particles have a saturated blue ink light black color and stable action on light and atmosphere. The present invention having high staining performance and high hiding power can be used for fine chemical engineering products, such as printing ink, carbon powder, etc. In the further scheme of the present invention, waste residues containing ferrous sulfate discharged in the production of titanium white powder are used for producing a ferrous sulfate water solution so as to produce oxidized iron oxide black, industrial waste materials can be fully used for producing high-quality oxidized iron oxide black products, and environmental pollution is reduced.

Description

A kind of production method of iron oxide black
Technical field
The invention belongs to a kind of production method of pigment, be specifically related to a kind of production method of iron oxide black.
Background technology
Iron oxide black is called for short iron black, and molecular formula is Fe 3O 4, or Fe 2O 3.FeO, chemical name is a Z 250, belongs to spinel type, also can be described as the ferrous and usefulness of ferrous acid
Figure C20051007511200031
Structural formula is represented.
Iron oxide black is because of opacifying power, strong coloring force, and light fastness is good and be widely used in fields such as paint, building materials, cement industry be painted, is widely used in fields such as printing ink, printing, coloring plastic, polishing and metal defect detection in addition.Prior art is generally used the direct addition method, be raw material promptly with the tankage of producing iron oxide red or iron oxide yellow, addition under certain processing condition, dehydration and generate the iron oxide black, the shortcoming of this technology is that the simple particle shape of the iron black product of gained is inconsistent, particle diameter is big and distribute very inhomogeneous, make red partially phase of form and aspect or yellow phase behind the pigment, fullness of shade and tinting strength are lower.In the existing in addition titanium white production, one ton of titanium dioxide of every production can produce the waste residue that the 3-4 ton contains ferrous sulfate, causes serious environmental to pollute.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of with the titanium white production waste residue be the iron black purity height of raw material, product, particle diameter is thin and evenly, tinting strength is high, has the production method of the iron oxide black of blue phase characteristics.
The technical scheme that addresses the above problem is:
1, the waste particle that contains ferrous sulfate that titanium white production is discharged drops into fully dissolving of heating in the water, and impurity titanyl sulfate wherein is hydrolyzed into the metatitanic acid precipitation, after settlement separate, get its clear liquor and makes perferrite solution;
2, make neutralizing agent and perferrite solution reaction generation ferrous hydroxide with caustic soda;
3, make oxygenant with oxygen-containing gas, generate iron black with above-mentioned hydroxide iron oxidation reaction;
4, sieve in the iron oxide black that will generate, press filtration, rinsing, oven dry, pulverizing promptly get blue phase oxidation iron oxide black pigment product.
Described perferrite solution can be that the ferrous waste residue of sulfur acid that Producing Titanium Dioxide is discharged is made ferrous sulfate aqueous solution through refining and edulcoration;
Described perferrite solution concentration is advisable with 5-50%, and preferred version is that ferrous salt content is 40-50%;
Described neutralizing agent caustic soda comprises liquid base, solid caustic soda, sheet alkali etc., and the gel pH value after the neutralization is 7.5-9;
Described oxygen-containing gas can be air or other oxygen-containing gas.
To be temperature carry out oxidizing reaction to described the 3rd oxidation reaction condition under 90-102 ℃, the condition of pH value at 7.5-9.
The inventive method is a raw material with the titanium white production waste residue, reduced environmental pollution, iron oxide black purity height, the crystal grain produced are thin, the pigment particle size of making is thin and even, and has a blue phase character of the black light black of saturated orchid, very stable to light and atmospheric action, strong coloring force, strong covering power can be used for fine chemical products such as printing ink, carbon dust.
Embodiment
Embodiment 1
The method that this example is produced blue phase oxidation iron oxide black pigment is:
1, the waste residue that contains ferrous sulfate of discharging in the titanium white production is put into dissolving tank, use steam heating, after abundant dissolving, standing sedimentation is got the clear liquor on its top, makes concentration and be 45% ferrous sulfate aqueous solution 2000Kg, puts into reaction vessel;
2, will generate ferrous hydroxide in the about 865Kg adding of the liquid caustic soda of neutralizing agent 30% ferrous sulfate aqueous solution while stirring, the system pH value is 8.5;
3, the ferrous hydroxide that makes is gone into the retort of 5000L with pump delivery, at 95 ℃, pH value is about 8.5 with the steam controlled temperature, and feeding flow while stirring is 0.3m 3The air of/min carries out oxidizing reaction and generates iron black;
The reaction formula in above-mentioned 2,3 steps is:
FeSO 4+2NaOH→Fe(OH) 2+Na 2SO 4
Fe(OH) 2+1/2O 2+H 2O→2Fe(OH) 3
Fe(OH) 2+2Fe(OH) 3→Fe(OH) 2·2Fe(OH) 3→Fe 3O 4+4H 2O
4, wet feed sieves: with the screening of sieving of 3 step gained slurries, sieve number is 320 orders;
5, filter-press water-washing: outsifting is put into water washing tank clean after-filtration;
6,5 gained filtrate are dried;
7, will dry thing and pulverize, make blue phase oxidation iron oxide black pigment.
This routine product contains Fe after testing 3O 496.5%; Specify the standard specimen ratio with industry, tinting strength is 160%.
Be the main technical data of embodiment 2-4 production method below:
Embodiment 2 Embodiment 3 Embodiment 4
In perferrite solution (concentration) neutralizing agent and back pH value oxidizing reaction temperature oxidizing reaction pH value 30% solid caustic soda 7.5 90 7.5 40% 42% liquid caustic soda 8 95 8 50% 30% liquid caustic soda 9 100 9
