Description
Technical field
The present invention relates to iron oxide brown preparation method, in particular to a kind of energy conservation and environmental protection preparation side of iron oxide brown pigment
Method.
Background technique
Iron oxide brown (Fe203+Fe0)·nH20 is a kind of brown-red powder, and not soluble in water, alcohol, is dissolved in strong acid at ether, simultaneously
Tinting strength, tinting power and covering power are very high, light resistance, and alkali resistance is good, no seepage of water and permeability.Its form and aspect are divided with the difference of technique
For：Reddish brown, yellowish-brown, black palm fibre etc., it is widely used in coloring and the coating of the products such as paint, ink, shoe powder, rubber, building
Coloring.
Traditional cologne earth is by the way that made of three kinds of iron oxide black, iron oxide yellow, iron oxide red pigment physics blendings, unstable product quality is held
Easy to knot groups, and form and aspect are uneven, and three kinds of pigment used, iron oxide black, iron oxide red, iron oxide yellow can all generate largely
Waste water so that environmental pollution is serious, the quality of iron oxide brown produced by the present invention is substantially higher in tradition as obtained by blending
The iron oxide brown arrived.Especially on temperature tolerance, its iron black temperature tolerance only has 110 DEG C after blending.Iron oxide produced by the invention
Palm fibre, heatproof can reach 650 DEG C, high as iron oxide red temperature tolerance.
Cologne earth process cycle is long disclosed in Chinese patent CN102502861A and technics comparing is complicated, there are also in
Iron oxide brown technique disclosed in state patent CN103318967A, reaction temperature is too high and inconvenient for operation, is not suitable for big
Production technology, but also a certain amount of nitrogen can be generated, cause environmental pollution.And the present invention is short reaction time, and benefit completely
With waste by-product, save the cost, if iron oxide red iron oxide yellow waste water is not used, not only increase enterprise's sewage treatment at
This, also results in the serious waste of iron resource, goes back welding, under the increasingly strict background of resource and environmental requirement, this hair
It is bright to be produced from resource-hungry, the production of resource reclaim recycling type is turned to, to improve the utilization rate of resource, is realized energy-saving and environment-friendly
Production requirement is the one third of cologne earth process cycle disclosed in Chinese patent CN102502861A, CN103318967A, and
And the present invention directly oxidative synthesis iron oxide brown pigment at normal temperature, technique is extremely simple, small investment at low cost.
Summary of the invention
In order to achieve the above purpose, the technical issues of purpose of the present invention mainly solves is to provide a kind of iron oxide brown
The energy conservation and environmental protection preparation method of pigment can efficiently use the iron oxide brown pigment of iron oxide red iron oxide yellow mother liquor production high quality,
The iron oxide brown pigment of this method production is rufous, has good tinting strength, tinting power, temperature tolerance, while also improving salvage property
Source utilization rate reduces environmental pollution.
In order to achieve the above purpose, above-mentioned technical problem is solved, present invention employs technical solutions below：
A kind of energy conservation and environmental protection preparation method of iron oxide brown pigment of the present invention, includes the following steps：
Iron oxide red iron oxide yellow mother liquor is added into oxidation barrel, turns waste into wealth by S1, raising resource utilization, energy conservation and environmental protection,
And it is not likely to produce waste water, quality is higher；
The compound alkali solid of macromolecule is added water, prepares saturated solution, operating procedure is simple, with short production cycle by S2；
S3 is passed through air in oxidation barrel, and the compound alkali saturated solution of macromolecule in S2 is added, makes solution pH value 7.5-
13, it carries out oxidation reaction 2-5 hours, obtains mixture, it is easy to operate, it does not need to stir, does not need to heat up, do not generate pollution；
Mixture in S3 is obtained iron oxide brown pigment through filters pressing, rinsing, drying, crushing by S4, easy to operate, production
Period is short.
Preferably, step S3 is carried out under normal temperature environment, simple to operate, is conducive to environmental protection.
Preferably, the pH value of solution is 8-9 in S3, improves resource utilization, energy conservation and environmental protection, quality is higher.
Preferably, oxidation time is 2-3 hours in S3, easy to operate, with short production cycle.
The present invention compared with the existing technology has the following advantages that and effect：Using waste by-product as raw material, simple process is raw
The production period is short, and the iron oxide brown pigment prepared has good tinting strength, tinting power, temperature tolerance and stability, and does not generate new industry
The three wastes, improve the utilization rate of resource, and energy conservation and environmental protection is conducive to the sustainable development of society.
Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
A kind of energy conservation and environmental protection preparation method of iron oxide brown pigment of the present embodiment, includes the following steps：
The recycle-water (mother liquor) for taking iron oxide red iron oxide yellow to produce is pumped into oxidation barrel；The compound alkali solid of macromolecule is taken, water is added
It is configured to saturated solution；Under room temperature, it is passed through air in oxidation barrel, the compound alkali saturated solution of prepared macromolecule is added, adjusts
Saving solution pH value in oxidation barrel is 8-9, is continuously passed through air, and control material liquid PH value is 8-9, is kept for oxidation reaction 2-3 hours；It will
