Description

A kind of porous light effectively insulating brick building face wall iron tailings base low bulk and Preparation technology
Technical field
The present invention relates to insulating brick technical field for building, particularly relate to a kind of face wall iron tailings base low bulk built Porous light effectively insulating brick and preparation technology thereof.
Background technology
Insulating brick is a kind of to have the heat-insulation and heat-preservation of irregular figure, lightweight refracrory, in building roof, inner-outer wall Face, building on the top of slope are built in the heat-insulation and heat-preservation engineering of roofing inside and outside base and are widely used, and are a kind of critically important construction materials, and it is very big The temperature improving building interior, improve the comfort level of house, the most light porous foam heat insulating brick is than traditional Overhead type insulating brick and to empty type insulating brick the most superior at effect of heat insulation and mechanical property, is that building face wall insulating brick is studied Emphasis.The foam heat insulating brick of existing market circulation is primarily present that price is the most expensive, service life is shorter, thermal resistance approach is single etc. and lacks Fall into, need to do further technological improvement.
China has abundant mineral resources, and along with expanding economy, substantial amounts of mineral resources are developed, and also produces simultaneously Substantial amounts of mine tailing waste material, especially iron tailings, volume of cargo in storage is up to tens00000000 tons, and its comprehensive reutilization problem has been subjected to entirely The extensive concern of society, if can will be turned waste into wealth by its rational exploitation and utilization, alleviates environmental problem and the office of shortage of resources Face." iron tailing sintered porous insulation material preparation technology and structural research " literary composition, with iron tailings as major ingredient, is viscous with bentonite Connecing agent, calcium carbonate is foaming agent, and sintering has been prepared as the construction material with certain heat insulation and preservation effect and load bearing effect, But preparation the material porosity on the low side, heat insulation and preservation effect still need to improve, do indoor heat-insulating heat-preserving material still can, in outdoor Face wall especially roof wall surface cannot meet demand, and use is restricted.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of building face wall iron tailings base low bulk Porous light effectively insulating brick and preparation technology.
The present invention is achieved by the following technical solutions:
A kind of porous light effectively insulating brick building face wall iron tailings base low bulk, it is characterised in that this insulating brick by with The raw material of lower weight portion prepares: iron tailings 40-50, lithium slag 20-30, beta-eucryptite 10-14, nano zircite 5-8, potassium nitrate 2-3, plant asphalt 4-5, cement 5-8, solid content are the Ludox 10-15 of 20-25%, sodium lignin sulfonate 4-5, water 30-50.
The preparation technology of described a kind of porous light effectively insulating brick building face wall iron tailings base low bulk includes Following steps:
(1) first after iron tailings, lithium slag, beta-eucryptite mix homogeneously, 200-300 mesh sieve was pulverized；
(2) being mixed with water by sodium lignin sulfonate, stirring adds plant asphalt, Ludox, nano oxidized to it after being completely dissolved Zirconium, adds step (1) material and other residual components after high-speed stirred mixing 4-5h, continues stirring mixing 60-80min, mixing Expect natural drying 2-3d after repressed molding, base substrate subsequently with the ramp of 5-10 DEG C/min to 900-950 DEG C, be incubated 2-3h Rear discharging, to obtain final product.
The present invention is using iron tailings as base material, using lithium slag, beta-eucryptite etc. as adjuvant, and with cement, plant asphalt, The raw material such as Ludox, sodium lignin sulfonate as bonding agent and porogen, after high temperature sintering formed have low thermal coefficient of expansion, The insulating brick base substrate of homogenizing loose structure, the nano zircite of addition gives the effect of heat insulation that brick body is excellent, has toughness reinforcing, increasing simultaneously Strong effect, iron tailings, lithium slag are effectively utilized by the insulating brick of the present invention, it is thus achieved that high fire-resistant compounding crystal phase structure, compounding Bonding agent and porogen make batch mixing more consolidation, base substrate is the most easy to crack, and pore amount is how uniform, effectively improves brick body Heat-insulation and heat-preservation ability, its low production cost, simple production technology, the performance of high-strength refractory so that it is at novel building wall The great market competitiveness in heat-insulation and heat-preservation field, face.
