Abstract
A process for preparing the iron oxide black from the Fe-mud dregs generated by iron powder reducing procedure includes such steps as removing impurities, water washing while sieving washing to pH 6-7, pressure filter, drying at 100+/-10 deg.C, and surface treating by stearic acid and carbon black. Its advantages are high content of Fe3O4 (70-95%), use of waste as raw material, and low cost.
Description
Technical field
The present invention relates to a kind of preparation method of pigment.
Background technology
In the Chemical Manufacture of using iron reduction method production technique, can produce a large amount of iron body refuses, at present, these iron body refuses all are just to be discharged in the environment without handling, and environment is caused serious pollution.
Summary of the invention
The purpose of this invention is to provide a kind of method of from the iron body refuse, producing black iron oxide pigment.
The objective of the invention is to realize in the following way: a kind of iron body refuse that utilizes iron powder reducing method production technique in the Chemical Manufacture to produce is produced the method for iron oxide black: with the selected impurity elimination of iron body refuse, in washing, cross 40 μ m sieve, being washed to PH is 6-7, under 100 ℃ ± 10 ℃ conditions, be dried to water content 0.5%-2% after the press filtration, pulverize, in pulverizing, carry out surface treatment with the stearic acid of 1%-5% and the carbon black of 1%-5%, make the iron oxide black of a kind of Z 250 content at 70%-95%.
The present invention has following beneficial effect, and the one, utilization of waste material has solved the discharging of iron reduction method production technique owing to scum mud, problem of environment pollution caused; The 2nd, the iron oxide black of producing with the present invention is to utilize waste residue to do raw material, and is therefore cheap, has marketable value.
Embodiment
The present invention will be further described below in conjunction with embodiment:
A kind of iron body refuse that utilizes iron powder reducing method production technique in the Chemical Manufacture to produce is produced the method for iron oxide black, with the selected impurity elimination of iron body refuse, in washing, cross 40 μ m sieve, being washed to PH is 6-7, under 100 ℃ ± 10 ℃ conditions, be dried to water content 0.5%-2% after the press filtration, pulverize, in pulverizing, carry out surface treatment with the stearic acid of 1%-5% and the carbon black of 1%-5%, make the iron oxide black of a kind of Z 250 content at 70%-95%.
Claims (1)
1, a kind of iron body refuse that utilizes iron powder reducing method production technique in the Chemical Manufacture to produce is produced the method for iron oxide black, it is characterized in that: with the selected impurity elimination of iron body refuse, in washing, cross 40 μ m sieve, being washed to PH is 6-7, under 100 ℃ ± 10 ℃ conditions, be dried to water content 0.5%-2% after the press filtration, pulverize, in pulverizing, carry out surface treatment with the stearic acid of 1%-5% and the carbon black of 1%-5%, make the iron oxide black of a kind of Z 250 content at 70%-95%.
