Description
Technical field
The present invention relates to compound and industrial waste recovery and utilization technology field, particularly a kind of method for preparing alumina sol.
Background technology
Alumina sol is a kind of inorganic polymer multivalence polymkeric substance, and its molecular formula is Al
2(OH) Cl
6-n, can be considered a kind of hydrolysate between aluminum chloride and aluminium hydroxide, therefore be called aluminium chlorohydroxide again.The preparation of alumina sol is by hydrochloric acid and metal aluminum shot thermopositive reaction to take place under certain condition, and aluminium dissolves in hydrochloric acid, hydrolytic polymerization forms, and chemical equation is as follows:
2Al+(6-n)HCl+nH
2O＝Al
2(OH)Cl
6-n+3H

Mainly as the caking agent of catalytic cracking catalyst, it can strengthen the abrasion resistance of catalyzer to alumina sol, can improve its reactivity again.In addition, alumina sol also can be used for preparing sapphire whisker, Electrostatic Treatment agent, permeability-reducing admixture, water conditioner etc.Use metallic aluminium production among the existing preparation method, not only cost is higher, and produces hydrogen in the preparation process, has potential safety hazard; And use organoaluminum as feedstock production aluminium colloidal sol, expensive raw material price, inflammable, poisonous is difficult for preserving, and brings difficulty to industrialization.
And the aluminium ash is the solid waste that aluminium electrolytic industry produces, and 1 ton of aluminium of general every production will produce 30～50 kg aluminium slag aluminium ashes.Usually all contain oxide compound, nitride and carbide, the salt of metallic aluminium, aluminium in the aluminium ash, other metal oxides are (as SiO
2, MgO) and some other compositions.Contain a lot of direct or indirect environmentally hazardous elements or compound in the aluminium ash (as Al
4C
3Meet water with AlN and can produce CH respectively
4And NH
3), if directly its landfill can be caused serious threat to environment.Therefore the recovery of aluminium ash and utilize the problem that become international.
Summary of the invention
The invention provides a kind of method that from the aluminium ash, prepares alumina sol, not only solved the problem that alumina sol prepares the raw material costliness, and provide new approach for harmless treatment aluminium ash.
Technical scheme of the present invention is:
A kind of method for preparing alumina sol comprises step:
A, the aluminium ash is added in the hydrochloric acid that concentration is 10-30%, keep 70-100 ℃, continue to stir 2-10h, filter behind the ageing 4-20h, described aluminium ash is 1: 5 to 1: 9 with the mass ratio of hydrochloric acid;
Dripping concentration in B, the filtrate that obtains after filter is ammoniacal liquor and the auxiliary agent of 1%-10%, and keeping temperature is 80-100 ℃, and described auxiliary agent is at least a in polyvinyl alcohol, polyoxyethylene glycol, acrylic resin, aluminum phosphate, the trimagnesium phosphate; Regulate pH value and stir 30min to 8-9, obtain alumina sol behind the ageing 6-12h.
Preferably, the interpolation speed of described aluminium ash is 1-5g/min.
Preferably, the described auxiliary agent adding proportion 0.1-0.3% that is described filtrate quality.
The method for preparing alumina sol from the aluminium ash provided by the invention has following advantage:
1, handles the aluminium ash: with the raw material of aluminium ash as the preparation alumina sol, consume industrial solid wastes aluminium ash, solve the environmental problem of the difficult difficult landfill of aluminium ash; And turn waste into wealth, reduce the preparation cost of alumina sol;
2, technology is succinct: aluminium ash and mixed in hydrochloric acid, metallic aluminium in the aluminium ash and acid-respons are become aluminum ion, after hydrolysis, polymerization form complicated polyvalent cation, add ammoniacal liquor and auxiliary agent again and regulate pH value, control aluminum ions hydrolysis, prevent from forming aluminum hydroxide precipitation; The various auxiliary agents that add then improve the dispersiveness of aluminium glue grain, prevent from reuniting, and make the alumina sol that obtains stable, transparent.
