Description
Technical field
The invention belongs to solid waste utilizes technical field, it is related to a kind of solid waste sintered porous heat insulation board and uses
Sintering fluxing agent and preparation method and application.
Background technology
Mine tailing is the discarded object after ore dressing, the chief component of industrial solid castoff.Countries in the world extraction every year
Metallic ore, nonmetallic ore, coal, clay etc. are up to 10,000,000,000 more than t, about 5,000,000,000 t of mine tailing amount of discharge, according to incompletely statistics, at present
The mineral products that China finds have kind more than 150, exploitation to establish more than 8000 mine, add up production 59.7 hundred million t of mine tailing, take up an area 80,000 hm2
More than, and still increased with the speed of 3.0 hundred million t every year.Mine tailing had both been occupied big using most of air storage for a long time
The soil of amount, is also easy to cause dust pollution, wherein harmful substance through weathering, drench with rain, the corrosion of rainwash is easy to dirt
Dye water body, endangers environment.
China's mill tailings main mineral constituent is by silicate, aluminosilicate, carbonate mineral and trace metallic mineral group
Into chemical composition is with SiO2、A12O3、CaO、MgO、Fe2O3、K2O、Na2Based on O, building ceramic material, glass and brick is close to
Composition watt required for grade, can as building, pottery, glass industry important raw mineral materials, with mine tailing do raw material make each
Building material product is planted, cost is relatively low, utilization rate is high and consumption big, both make use of waste, and reduced environmental pollution, saved again a large amount of
Soil.Therefore, the whole utilization of mine tailing has important economic worth and development prospect.
Building energy consumption accounts for China's total energy consumption more than 1/3, and insulating layer of external wall effectively can completely cut off heat exchange and substantially reduce energy
Consumption.But, Shanghai " 11.15 " fire incident, the new building big fire of CCTV etc. are taken place frequently by fire caused by building thermal insulation material, are caused tight
The casualties and property loss of weight, makes insulation material fire safety unprecedentedly be paid close attention to by the public.Fire takes place frequently, and has expedited the emergence of China
Most severe building thermal insulation material fire protection regulation in history.On January 20th, 2012, house and town and country construction portion print and distribute《Close
In carrying out State Council with regard to strengthening and improving the notice of firemanic suggestion》, it is desirable to architectural exterior insulation material is strictly held
The row Ministry of Public Security, house and town and country construction portion combine and print and distribute《Civil buildings exterior wall heat-preserving system and the provisional rule of decoration of exterior wall fire prevention
Fixed》（Public logical word (2009) 46）, the combustibility preferably A levels of civil buildings heat insulating material for external, and not lower than B2 levels
（Combustible material）；Using B1（Nonflammable material）During with B2 level insulation materials, fire-blocking belt should be set according to the rules.
At present, the A levels fire-retardant heat-insulation material on market mainly has rock cotton board (bar）, composite cement foam warming plate, aerating
4 class such as concrete slab, exterior insulation, rock wool contain a large amount of inorfils, have a strong impact on environment and health, and easily
Water suction, easily contraction；Composite cement foam warming plate, aerated concrete panel water absorption rate are big, low intensity, easy to crack, and thermal conductivity factor
Affected by production technology larger, wayward；Exterior insulation is a kind of new inorganic ceramic insulation material, using nothing
Machine ceramic material as primary raw material, through the closed-cell foam ceramic thermal insulation material of the high porosity of high-temperature roasting.Have
Good heat insulating, fire-protection rating height, little, anti-aging deformation coefficient, stable performance, good eco-environmental prote and plinth course and wipe one's face
Layer compatibility good, security and stability is good, can with building with the life-span the features such as.It can be seen that, exterior insulation is that one kind compares
Preferable wall heat insulation material, but, due to will be through 1200 DEG C of high-temperature roasting so that its material price itself is slightly higher, advises
Modelling application is restricted.Therefore, if firing temperature can be greatly reduced from suitable flux, and on a large scale using useless
Tail dropping ore deposit, so that it may reduce the production cost of exterior insulation in terms of energy-conservation and environmental protection two, expand its range of application.
Therefore, on the premise of existing production technology and working condition is not substantially changed, exploitation is suitable to high additive mine tailing
The sintering fluxing agent of sintered porous heat insulation board is significant to the production cost for reducing exterior insulation.Chinese special
Profit number for ZL200910023626.3 patent of invention specification in disclose a kind of iron tailing sintered porous heat insulation board, its
In：Iron tailings utilization rate be 10%～40%, Mine Tailings Utilization is relatively low, additionally, flux be borax, potassium feldspar, albite and
One kind in lead oxide, at 1200 DEG C, firing temperature is slightly higher for firing temperature.China Patent No. sending out for ZL201210190895.0
A kind of foamed ceramic material and preparation method thereof is disclosed in bright patent specification, and Mine Tailings Utilization can reach 65～85%, flux
Agent is sodium carbonate, calcirm-fluoride, at least one in sodium phosphate, but swelling temperature be firing temperature for 1225～1300 DEG C, burn
Higher into temperature.In sum, do not account for carrying out reasonable compatibility to flux in foregoing invention patent specification, not from
The high additive mine tailing sintering that high additive proposes to be suitable to existing production technology and working condition using mine tailing and low-temperature sintering angle is more
Sintering fluxing agent of hole heat preservation plate material and preparation method thereof.
