Description
Technical field
The invention belongs to building masonry wall lagging material technical field, the uninflammability that particularly a kind of thermal conductivity is low is mixed warming plate and preparation method thereof.
Background technology
Along with the development of society, increasing buildings has consumed a large amount of Nonrenewable resources and the energy; Particularly a large amount of bad buildingss of heat insulating effect not only make the more energy of winter heating and summer refrigeration consumption, also cause a large amount of environmental pollutions, and are incompatible with the present low-carbon economy of advocating; The insulation way of traditionally buildings being taked is to add thick wall body, and so not only cost is high, also consumes a large amount of buildings and resources; Development along with material of construction science and technology, the wall thermal insulating lagging material is more and more, but most of material all is that the building resource that consumes is many, and cost is high, and the insufficient strength of material, quality is unstable, the defect such as hollowing, efflorescence, cracking easily appear, have in addition also do not prevent fires, not only affect construction quality, also be difficult to reach the insulation requirement, even potential fire hazard is arranged.
Main heat-insulating construction material has styrofoam, granular polystyrene and inorganic heat insulation mortar in the market.Wherein the thermal conductivity of styrofoam is low, high insulating effect, but inflammable, do not prevent fires, now banned use of by country.In recent years, do exterior-wall heat insulation because of styrofoam, the fire that causes can't be estimated to the loss that country brings.And its work-ing life can not exceed 25 years, existing building life 70 years is done exterior-wall heat insulation as adopting styrofoam, means that resident family also will drop into 2 times of existing cost in 70 years, do again again.The heat insulation effect of granular polystyrene is also good, but does not inflammablely prevent fires, and bonding strength is poor, belongs to officially eliminated by the State backward products.Although inorganic heat insulation mortar belongs to A level non-fire material, thermal conductivity is higher, and heat insulation effect is general.
The patent No. 200410020984.6 has been announced " compound heat-insulation board of outer wall and production method thereof ", and the method adopts resin or foam production warming plate, and fire resistance is poor, and potential safety hazard is arranged; Number of patent application 200710001005.6 has been announced " cement mixing warming plate and exterior-wall heat insulation technique ", and the method is that heat-insulating granules is bonded to warming plate with cement, is bonded to grout and does thermal insulation layer on the wall face.Although this warming plate can reach certain heat insulating effect, not fire-retardant, in addition combustion-supporting, be not suitable for applying; Number of patent application 2005100296730 has been announced " heat insulating inorganic mortar " this mortar and has been comprised of cement, natural aglite and high molecular polymer, although this mortar can reach heat insulating effect, but own wt is large, and adhesiveproperties is poor, and net effect is also undesirable.
Summary of the invention
Technical problem to be solved by this invention is larger for the currently available products deadweight; not fire-retardant; the shortcoming that intensity is low, adhesive property is low, thermal conductivity is high, organic materials discharges obnoxious flavour; a kind of mixing warming plate take expanded and vitrified small ball, high-strength cement, quality oxide calcium, calcium hydroxide as core is proposed; improve heat insulation usefulness to reach; reduce deadweight, improve adhesive property, incombustible effect.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is to mix warming plate and preparation method thereof, mixes warming plate and is added water and mixed by expanded and vitrified small ball, cement, calcium hydroxide, calcium oxide, Germany's watt gram rubber powder, PP fiber, flyash, hydrophober, air entrapment agent, hardening accelerator, methylcellulose gum; Its thickness is 1-4cm; Its component weight proportion is: expanded and vitrified small ball 350-430 part, cement 250-350 part, calcium hydroxide 10-150 part, calcium oxide 50-80 part, Germany's watt gram rubber powder 70-150 part, PP fiber 10-50 part, flyash 40-150 part, hydrophober 1-3 part, air entrapment agent 2-5 part, hardening accelerator 1-3 part, methylcellulose gum 1-5 part, water 560-1000 part; Wherein the specification of calcium hydroxide is that the specification of 100-150 orders, calcium oxide is that the specification of 200-250 orders, PP fiber is 6mm.
The preparation method who mixes warming plate is.
⑴ fly-cutter type stirs: with the fly-cutter type stirring means cement, calcium hydroxide, calcium oxide, Germany's watt gram rubber powder, PP fiber, flyash are fully stirred, make to stir.
⑵ drum-type stirring: add again expanded and vitrified small ball in the batch mixing after stirring and carry out drum-type stirring.
⑶ mortar processed: then hydrophober, air entrapment agent, hardening accelerator and methylcellulose gum are added to the water, carry out together drum-type stirring with batch mixing again, form mortar.
⑷ fill molded panel: then mortar is sent into vibratory compaction in the warming plate forming mould.
⑸ toast typing: and then the moulding plate toasted, progressively be raised to 150 ℃ of bakings typing in 90-110 hour from 40 ℃, make the mixing warming plate.
The invention has the beneficial effects as follows that to have thermal conductivity low, do not burn, the superior characteristics such as weather resistance is good, intensity is high, adhesive property is good, the easy performance of living is excellent, easy construction, long service life; Particularly the reexpansion of material in stirring, initial set process forms the cellular closed pore of internal diameter 0.5-1.0mm, when reducing thermal conductivity, reduction deadweight, raising heat-insulating property, reduced the usage quantity of material, saved construction cost; Through check, thermal conductivity of the present invention is less than 0.065W/mk, and the present invention is suitable for the construction wall lagging material of Xia Redong cryogenic region, has wide market outlook.
