Description
Technical field
The present invention relates to a kind of lagging material, specifically a kind of lagging material that is used for building masonry wall, pipeline, container etc.
Background technology
China pays much attention to building energy conservation, and the mandatory requirement building energy saving rate is not less than 50%, and pertinent data shows, the power loss that the wall heat transfer causes is about 1/3 of the total power consumption of building, so wall thermal insulating is the important step of building energy conservation.
At present in the world with polystyrene foam plate and urethane foam-in-place plate as main lagging material.China also is to use the main construction techniques of this method as wall thermal insulating at present.The essential structure of polystyrene foam plate composite polyphenylene granule exterior wall heat preserving technology: basic unit's metope, polystyrene plate bond, polystyrene board, anticracking grout, reinforced grid cloth, priming paint, putty, finish coat.The essential structure of polyurethane coating External Thermal Insulation Technology for External: basic unit's body of wall, polyurethane primer, polyurethane insulation coating, boundary mortar, lightweight leveling material, anticracking grout, composite gridding cloth, putty, exterior coating (if outer tiling, it is fixed then to add anchoring in alignment material in addition).
There are a lot of problems in use in polystyrene foam plate and urethane foam-in-place plate: the heat insulation effect that (1) will realize, must increase the thickness of thermal insulation layer, when the polystyrene board of light specific gravity or polyurethane foam board increase considerably thickness, bigger distortion can take place owing to the thermal insulation layer thickening in the surface layer of identical load, thereby the junction that causes polystyrene board or polyurethane foam board produces more problem, for example run into and blow, polystyrene board or polyurethane foam board will big area come off, bring great difficulty to construction, be difficult to guarantee construction quality, but also exist potential safety hazard; (2) normally used styrofoam matrix material is a methylcellulose gum mediation sand-cement slurry, because polystyrene board and polyurethane foam board are organism, aging time is difficult to grasp, in case the aging time of lagging material has arrived, hollowing must occur with body of wall agglutinating material so, as run into natural disaster, as meetings such as strong wind insulating layer of external wall is peeled off, lose heat insulation effect, cause the body of wall accumulation of salt in the surface soil, humidity; (3) fusing point of polystyrene foam plate and polyurethane foam board is low, inflammable, in case run into fire, consequence is hardly imaginable.And it contains freonll-11, can produce poison gas after the burning, and is incompatible with the environmental protection system of current each national regulation; (4) external-wall heat-insulation material of polystyrene foam plate and polyurethane foam board, its price of every square metre does not wait in 80-180 unit, and for the people in the countryside that account for Chinese population 69.11%, Ang Gui price is unacceptable like this; (5) energy-saving effect is not remarkable, and the polystyrene foam plate that uses and the thickness of polyurethane foam board are 6 centimetres at present, just can reach energy-conservation 60%.
Except polystyrene foam plate and urethane foam-in-place plate, the lagging material of often using on the market also has Calucium Silicate powder, glass fibre, mineral wool, multicellular glass etc.Easily there is corrosive calcium oxide in calcium-silicate thermal insulation material containing under the moisture state; There are easily absorption moisture in glass fibre and mineral wool, are not suitable for the shortcoming of low temperature environment; Multicellular glass is not owing to the thermal shocking sensitivity, be suitable for temperature state jumpy.
Pearlstone is a kind of fine inorganic heat insulation material, a large amount of application is at home and abroad all arranged, as all disclosing the lagging material that contains pearlstone at Chinese patent literature CN1172869C and CN1176868C, first kind of its component of lagging material comprises sepiolite, pearlstone, quartzy, aluminosilicate fiber cotton, water glass, 1788 glue, second kind of its component of lagging material comprises pearlstone, vermiculite, float pearl, fine particle calcium carbonate, coarse whiting, flyash, semi-hydrated gypsum, cellulose fiber peacekeeping methylcellulose gum, yet the problem that these expanded perlite thermal-nsulation materials exist is, (1) used water glass in large quantities for the intensity that improves material, flyash, inorganic adhesives such as semi-hydrated gypsum, (dry density of material is at 280-300kg/m thereby cause the unit weight of material higher
3, and the dry density of lagging material of the present invention is at 200kg/m
3Below), heat insulation effect poor (thermal conductivity is at 0.06-0.07W/mK, and the thermal conductivity of lagging material of the present invention is about 0.05W/mK); (2) unit weight of material is big, and then the relation owing to gravity is difficult for construction molding under wet condition; (3) pearlstone has a lot of micropores, uses the inorganic adhesive moulding merely, can not these micropores of complete closed, thus cause the water-intake rate of material higher, freeze-thawing resistant, easily aging not; (4) inorganic adhesive is poor in the early solidification cohesive strength, hollowing can occur in the construction, also has problems such as dry shrinkage and cracking when solidifying; (5) the part lagging material also contains just like carcinogenic, radioactive harmful materials such as sepiolites.All these problems have caused the overall performance deficiency of expanded perlite thermal-nsulation material, have directly influenced the application of pearlstone aspect lagging material.
