Description
Technical field
It is especially a kind of to prepare baking-free lightweight guarantor with mineral wool slag ball the present invention relates to a kind of construction material and preparation method thereof
Warm brick and preparation method thereof.
Background technology
Molten blast furnace slag is one of principal by product of blast furnace, while is also the chief component of steel factory waste residue.It is logical
Often, molten blast furnace slag per ton contains (126~188) × 104KJ sensible heat, equivalent to the energy of 30~40kg heavy oil, Er Qieqi
With higher temperature, about 1450~1600 DEG C, belong to the residual heat resources of high-quality, there is very high recycling to be worth.Return
It will be that enterprise reduces production cost to receive this part sensible heat, create economic benefit.
At present, domestic and international blast furnace cinder is more based on water quenching, although there is minor heat can be by the form of remaining hot water
Reclaimed, but most of energy can not all realize recovery, cause huge energy waste.It is and molten state blast furnace slag is directly raw
It is that an extraordinary blast furnace cinder comprehensively utilizes mode to produce as high value added products such as mineral wools, and it can not only realize blast furnace slag height
The direct utilization of quality waste heat, and the high added value comprehensive utilization of blast furnace slag can be realized, it is China's smelter in recent years
One important development focus.However, blast furnace slag production mineral wool product will necessarily generating unit be divided into fine poor chopped fiber flying chip,
Contaminated fiber flying chip etc. near fiber powder and production line including dust pelletizing system recovery, also have in addition not into the slag ball of fibre
Deng, because it is inorganic lightweight material, pack compression difficult, transport difficult, stockpiling or landfill after be difficult in natural environment
Resolution, causes obvious secondary pollution.And rejoin mineral cotton smelter not only operation difficulty is big, and significantly affect mineral wool production
Efficiency and product quality, processing cost substantially increase.Therefore, the processing of mineral wool production discarded object is as the great of mineral wool industry
Problem.Because mineral wool fiber has the characteristics that anti-corrosion, insulation, tensile strength are high, if insulating brick raw material will be used as not only to disappear
A large amount of mineral wools of receiving produce accessory substances, and can realize the harmless treatment of mineral wool waste material, and economic benefit is obvious.
The Patents of insulating brick are prepared with mineral wool fiber flying chip both at home and abroad and document is not found, it is discarded with blast furnace slag etc.
Thing prepares the related patent of insulating brick and document is relatively more, as Chinese Patent Application No. is 201210542011.3, entitled《One
Kind Superfine slag powder baking-free brick and its production method》Patent of invention, its main contents is：It include mass percent be 15~
25% slag micropowder, 35~45% slag, 8~15% flyash, 20~25% lime stone, 10~15% water,
Each ingredient percent sum is not more than 100%.Described production method includes dispensing, stirring, base, maintenance process.Should
Cement during invention replaces tradition non-burning brick using slag micropowder is used as cementing agent, reduces non-burning brick production cost, and slag adds
The features such as entering to reduce the use of the non-burning brick aggregate of tradition.And for example Chinese Patent Application No. be 200810014015.8, it is entitled《One
Kind steel scoria unburned brick》Patent of invention, its main contents is：Its raw material includes Steel-slag Sand, steel-making slag powder, blast furnace slag, lime.System
Making the method for the steel scoria unburned brick is, adds water to stir load weighted raw material, compressing to brick machine, then through maintenance,
Finished product steel scoria unburned brick is obtained after ageing.Both the above is non-burning brick to have the problems such as big unit weight, poor thermal insulation property, it is difficult to is building
Thing agent structure is built as building main material by laying bricks or stones to use, hence it is evident that limit the application of product, economic benefit is poor.
In a word, in the prior art mineral wool fiber prepare baking-free lightweight insulating brick correlation technique it is less, and in the prior art
The problems such as big unit weight, poor thermal insulation property, high production cost be present in insulating brick.
The content of the invention
The present invention provides a kind of baking-free lightweight insulating brick and preparation method thereof, overcomes the shortcomings of the prior art, can incite somebody to action
Mineral wool produces waste material and chopped fiber and is made non-burning brick, and small investment, technique is simple, and unit weight is small, good heat insulating, sound absorption properties good, raw
It is low to produce cost.
In order to solve the above problems, the present invention uses following technical scheme：
A kind of baking-free lightweight insulating brick, it includes the mineral wool waste material that mass percent is 30~70%, 10~35% water
Mud, 0~22% flyash, 5~10% water.
The mineral wool waste material is slag wool fiber or rock wool fibers containing certain slag ball, its shot content >=50%.
The mineral wool waste material is by broken, fibre length≤15mm, slag spherolite footpath≤3mm.
The cement is 32.5 grades of portland slag cements.
The flyash sieves by removal of impurities, to ensure that wherein the debris such as comprising metal wire, grass roots, granularity are not below 1mm.
A kind of preparation method of baking-free lightweight insulating brick, including dispensing, stirring, base, maintenance process, are specifically included：
Dispensing, prepare mineral wool waste material, cement, flyash, water in proportion；
Stirring, is first put into mineral wool waste material and cement, flyash, is then proportionally added into water and is stirred 10~20min and obtains
To compound；
Base, compound is obtained into adobe through vibrating forming；
Maintenance, baking-free lightweight insulating brick is obtained after the maintenance of adobe normal temperature.
During natural curing, fetch water 3~5 times, maintenance can dispatch from the factory for 5~18 days.
The thermal conductivity factor of the insulating brick is 0.050~0.070W/mK.
The acoustic absorptivity of the insulating brick is 2.10~2.50.
The unit weight of the insulating brick is 850~1150g/cm3。
The present invention has the advantages that compared with prior art：First, realize mineral wool waste residue, the innoxious of fiber of giving up
Processing, solves the problems, such as the secondary pollution of mineral wool waste material；Second, the insulating brick technique that mineral wool waste residue, useless fiber are produced is simple, throw
Money is few, and cost is low, and application is wide；Third, the good heat insulating of insulating brick, sound absorption properties good, unit weight is small, service life length etc..
Therefore, the present invention has obvious economic benefit and environmental benefit, and in industry slag directly produces mineral wool product and uses field
There are obvious economic benefit and popularizing value.
