Background technology
The housing industry of China, through development rapidly, is in an important developmental stage now, and Chinese Housing is built
If the development intensive by extensive orientation direction, the construction and development of housing stage of sophistication be unable to do without home building industry
Direction.Full assembling dwelling house system promotes dwelling house system as Minstry of Housing and Urban-Rural Development of People Republic of China's emphasis, needs a complete supporting environment badly and pushes away
Its development dynamic, supporting Side fascia system time is the most requisite ring.
Although there being a large amount of sheet material kind on domestic market, but can realize on-the-spot full assembling can meet again insulation, heat insulation,
Sound insulation, durable, in addition it is also necessary to meet the Side fascia of economy few.
Coal is as primary energy, and in China's energy resource structure, proportion reaches, and its main energy position is constant.Coal is wicked
Stone is to open and a kind of solid waste of generation in the course of processing at coal.Coal traitor's stone not only occupies substantial amounts of soil, dirty
Dye environment, more serious threat the healthy of the mining area people.But it practice, coal traitor's stone is also a kind of natural resources, building materials,
The fields such as chemical industry, metallurgy and light industry have a wide range of applications.Therefore, science, reasonably utilize coal hepatolith, good warp can be produced
Ji benefit, social benefit and environmental benefit.
Summary of the invention
For solving the problem that prior art exists, the present invention provides a kind of novel compound external wall panel and production technology, both
Make use of this domestic mass storage of gangue to continue the ep-type material of twice laid, reduce cost and meet national green
The theory of low-carbon (LC), uses again hard polyurethane foams to meet the requirements such as the insulation needed for Side fascia, sound insulation.
For achieving the above object, the technical solution used in the present invention is:
A kind of novel compound external wall panel, including coal gangue concrete, hard polyurethane foam central layer, the word steel of steel wire net rack sum
Silk.
The production technology of described a kind of novel compound external wall panel, comprises the following steps:
A. the production technology of coal gangue concrete
1) selection of raw material: select there is the gangue of following chemical composition as the lightweight aggregate making gangue: loss on ignition 1 ~
20%, SiO230 ~ 40%, Fe2O35 ~ 15%, Al2O320 ~ 30%, CaO 1 ~ 3%, MgO 0.5 ~ 1%；
2) crushing and screening: after gangue crusher in crushing, sieves the lightweight aggregate into different-grain diameter, should reach claimed below:
Coarse aggregate size is: the granule of 5 ~ 30mm, 30 ~ 40mm is less than 10%, and the granule less than 5mm is less than 15%, and fine aggregate is medium and small
In 0.15mm powder less than 10%；
3) stirring: each composition material is weighed according to following proportioning: gangue 40-50%, cement 15-23%, medium sand 25 ~ 28%, water
5-12%, mixing and stirring；
4) molding and maintenance: after stirring, enters mould pouring, extruded with mechanical forming method, uses steam curing method, maintenance
40h, obtains coal gangue concrete；
B. the production technology of compound external wall panel
Selecting steel wire as rack, rack thickness is 76mm, inside fills out hard polyurethane foams central layer, and the thickness of central layer is 50mm,
Central layer is inserted into fixation with steel wire in a zigzag, together with central layer, rack is put into template and is fixed, then on its two sides respectively
Pouring coal gangue concrete, pouring thickness is 50mm, vibrates, floating and steam curing obtains finished product.
The described steel wire as rack is cold-drawn zinc-coated wire.
Beneficial effects of the present invention:
Present invention utilizes this domestic mass storage of gangue and continue the ep-type material of twice laid, reduce cost and full
The theory of foot national green low-carbon (LC).
But the coal gangue concrete lightweight that the present invention uses, high-strength, viscosity good, fire-retardant, good economy performance humidity resistance relatively
Difference, heat-proof quality are general, the caking property of polyurethane foam plastics light weight, heat insulation, moistureproof, corrosion resistant candle and base material well but intensity
Low, inflammable, therefore, the filled board of coal gangue concrete plate with polyurethane foam plastics plate bonding can be reached outside building
Lightweight that wall requires, heat insulation, sound insulation, moistureproof etc. require to meet again cost-effectiveness requirement.
The hard polyurethane foam that the present invention uses is less dense cores, and the density of coal gangue concrete is also mixed less than tradition
Solidifying soil, the coal gangue concrete polyurethane sheet therefore with same load ability is lighter than conventional entity plate, and polyurethane foam
Foam is as damping material, it is also possible to plays damping layer and consumes detrusion energy, becomes constrained damping structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of compound external wall panel.
