Abstract
The invention discloses an ore tailings ceramsite air brick and a preparation method thereof. The ore tailings ceramsite air brick is prepared from the following raw materials in parts by weight: 20-30 parts of slate, 30-50 parts of coal gangue, 15-20 parts of building rubbish, 10-15 parts of modified loess, 8-12 parts of quicklime powder, 15-25 parts of ore tailings, 5-10 parts of rice husk, 8-12 parts of barite, 10-15 parts of limestone, 5-10 parts of volcanic ash, 3-6 parts of aluminum silicate fiber, 2-4 parts of calcium sulfate whisker and a defined amount of water. According to the invention, ore tailings are taken as the main raw material to prepare ceramsite to produce the air brick, which not only reduces a great amount of cultivated land occupied by accumulated iron ore tailings and environment pollution, but also improves the heat-insulating property and mechanical strength of the air brick. The air brick provided by the invention has the advantages of high strength, low density, good heat-insulating property, anti-seismic property and weatherability, environmental friendliness, energy conservation and the like and is suitable for large-scale popularization and application.

Hollow brick is building trade body of wall master material commonly used, due to light weight, consume the advantages such as former material is few, has become the product that at first national construction sector is recommended.But the heat insulation property of the hollow brick on market, ultimate compression strength etc. still can't reach country's insulation or quality control requirement now.
Summary of the invention
The object of the present invention is to provide a kind of ore tailing ceramsite hollow brick and preparation method thereof, the haydite production hollow brick that the ore tailings of take makes as main raw material, not only reduced adopting iron ore tailings because accumulation has taken a large amount of arable lands, reduce environmental pollution, also improved heat-proof quality and the physical strength of hollow brick.
The technical solution used in the present invention is as follows:
A kind of ore tailing ceramsite hollow brick, by the raw material of following weight part, made: shale 20-30, coal gangue 30-50, building waste 15-20, modified Loess 10-15, calcium lime powder 8-12, ore tailings 15-25, rice husk 5-10, barite 8-12, limestone 10-15, volcanic ash 5-10, aluminum silicate fiber 3-6, calcium sulfate crystal whiskers 2-4, water are appropriate.
Described ore tailings is selected from one or more in iron ore tail sand, Copper Ores tailings, Gold Ore tailings, zinc ore tailings, aluminum ore tailings, tungsten ore tailings.
Described modified Loess preparation method is as follows: get wollastonite powder, the vermiculite power of 3-5%, the cinder of 2-3% and vinyl three ('beta '-methoxy oxyethyl group) silane of 1-2% that a certain amount of loess adds 2-3%, 2000-3000rpm stirs 10-15min, calcine 1-2h under 740-760 ℃, cooling rear fragmentation adds the Starso that is equivalent to loess weight 2-3%, the carboxymethyl cellulose of 2-3% and the tripoly phosphate sodium STPP of 3-4% again, and 1500-2000rpm stirs 20-30min and gets final product.
A kind of preparation method of ore tailing ceramsite hollow brick comprises the following steps:
(1) by ore tailings, rice husk, coal gangue, limestone, volcanic ash, aluminum silicate fiber, calcium sulfate crystal whiskers through the mechanical disintegration powder, by formula rate, stir, then add the water that volume ratio is 10-15%, then make through nodulizer the raw material ball that particle diameter is 2-5mm, dry 3-5h under 110-120 ℃; Dried raw material ball, at 1150-1250 ℃ of lower high-temperature roasting 6-8min, is obtained to the ore tailing ceramsite;
(2) surplus stock is added to appropriate water and stir, then add the above-mentioned ore tailing ceramsite made, rear input ageing storehouse ageing stirs, raw material after ageing is carried out to the secondary mixing, stirring velocity is 800-1000rpm, and churning time is 10-20min, and moisture control is at 15-20%;
(3) compound after stirring is through the brick extruding machine extrusion moulding, and extrusion pressure is 2.0-2.5MPa;
(4) adobe is sent into to drying in dry kiln, then the adobe of oven dry is sent into to the roasting kiln roasting and be finished bricks.
Beneficial effect of the present invention:
The present invention be take the haydite that the ore tailings makes as main raw material and is produced hollow brick, not only reduced adopting iron ore tailings because accumulation has taken a large amount of arable lands, reduced environmental pollution, also improved heat-proof quality and the physical strength of hollow brick.Hollow brick of the present invention has the advantages such as intensity is high, density is low, thermal and insulating performance is good, anti-seismic performance is good, good weatherability, environmental protection and energy saving, is applicable to large-scale promotion application.
