Abstract
The invention discloses an electrolytic manganese residue (EMR) light-weight insulating brick and a preparation method thereof. The insulating brick comprises the following components according to ratio by weight: 60-70 of EMR, 5-10 of calcium oxide and 0.5-1 of surface active agent, wherein the components are mixed, mechanically stirred through adding water, injected into a mould for vibration moulding, and maintained naturally. The obtained manganese residue brick is greater than 10MPa in compressive strength, is 4.5MPa in flexural strength and 1000kg/m3 in density. Industrial solid wastes are effectively used, pollutions to environment are reduced, and manganese residues are unnecessary to dry during the manufacturing procedure, so that energy consumption can be greatly reduced.
Description
Technical field
The present invention relates to a kind of electrolytic manganese residues light-weight insulating brick, this insulating brick is used for building non-bearing wall body and greenhouse wall body, belongs to novel material and changing rejected material to useful resource technical field.
Background technology
Electrolytic manganese residues is to adopt electrolysis process to produce the acid-soaked waste residue that produces in the manganese metal process, main producing country as world's electrolytic manganese, about 6,000,000 tons of the nearly 1,000,000 tons of discharging electrolytic manganese residues of China recent years output need use a large amount of land resourcess to its stacking, increase the disposal costs of enterprise; Electrolytic manganese residues contains a certain amount of harmful element simultaneously, lets alone discharging and can cause serious environmental pollution.Therefore electrolytic manganese residues is effectively utilized, bring certain economic benefit can not only for electrolytic manganese production enterprise, the more important thing is fundamentally thoroughly to solve electrolytic manganese residues to the pollution of environment.According to domestic existing patent report, the existing electrolytic manganese residues of taking is produced gas concrete; There also have the electrolytic manganese residues of employing to produce to be non-burning brick.But adopt electrolytic manganese residues to produce the baking-free lightweight lagging material and not yet see report.
Summary of the invention
The objective of the invention is, for taking full advantage of discarded electrolytic manganese residues, alleviate it to the pollution of environment, a kind of electrolytic manganese residues light-weight insulating brick and preparation method thereof is provided.
Described electrolytic manganese residues light-weight insulating brick, add the water mixing by electric manganese manganese slag, unslaked lime, cement, pearlstone and tensio-active agent again and make by mould afterwards, the weight ratio of each component is: electrolytic manganese residues 60-70, unslaked lime 5-10, cement 10-20, tensio-active agent 0.5-1.
Described tensio-active agent is alkylbenzene sulfonate or sodium lignosulfonate.
Described electrolytic manganese residues light-weight insulating brick preparation method's step is:
A, outfit starting material: starting material component and each components by weight are: electrolytic manganese residues 60-70, unslaked lime 5-10, cement 10-20, tensio-active agent 0.5-1;
B, unslaked lime is mixed with electrolytic manganese residues and display and carried out pre-treatment in 24 hours;
C, adding cement, pearlstone and tensio-active agent mix, and add water and stir;
D, the compression molding of employing semidrying, natural curing after the moulding.
Electrolytic manganese residues insulating brick ultimate compression strength of the present invention〉10MPa, folding strength 4.5MPa, density 1000kg/m
3, not only can effectively utilize industrial solid castoff, reduce the pollution to environment, and need not dry the manganese slag in the preparation process, can save a large amount of energy consumptions.
