Abstract
The utility model relates to a building wall, in particular to an environment-friendly thermal-insulation external wall. The environment-friendly thermal-insulation external wall is characterized in that a moisture-proof polyurethane prime layer is applied on the upper surface on the upper surface of a base wall uniformly; a polyurethane rigid foam thermal-insulation layer is uniformly sprayed on the upper surface of the moisture-proof polyurethane prime layer; a polyurethane interface mortar layer is uniformly applied on the interface of the polyurethane rigid foam thermal-insulation layer; an adhesive polystyrene granule thermal-insulation layer is uniformly applied on the upper surface of the polyurethane interface mortar layer; and an external decorative layer is sprayed on the upper surface of the adhesive polystyrene granule thermal-insulation layer. The moisture-proof polyurethane prime layer applied on the base wall can eliminate water and moisture to effectively improve the moisture content of the base wall and to prevent moisture permeation in the later construction process; the polyurethane rigid foam thermal-insulation layer is sprayed directly and can be attached to the base wall firmly to seal the space and to prevent delamination. The environment-friendly thermal-insulation external wall has the advantages of long service life, good waterproof effect, low moisture absorption, reliable waterproof performance, and can prevent increase of the thermal conductivity due to moisture absorption, thereby achieving integration of thermal insulation and water resistance.
Description
One, technical field:
The utility model relates to building thermal insulation material, particularly the building heat preservation body of wall.
Two, background technology:
Hard polyurethane foam (be called for short PUF) is a kind of synthesized polymer material, mainly by polyisocyanates (NCO group) Yu Duo Hydroxyalkyl based compound (OH group) chemical reaction form.That PUF has again is soft, semi-rigid, from the branch of skinning, hard, that wherein building thermal-insulation energy-saving is mainly used is hard PUF.The PUF raw material that hard bubbles mainly is two component liquid form supplies of material, and wherein the A component is a combination ingredient, is made up of multiple components such as polyalcohol (ether type, ester type), blowing agent, catalyzer, foam stabilizer, fire retardants.The B component is that single composition polyisocyanates is formed.At a certain temperature, chemical reaction takes place after mixing in A, B component at short notice, forms urethane polymer---and be called for short polyurethane, himself chemical heat release makes its blowing agent gasification, forms the resin expanded expansion of PU, just forms PUF after solidifying.
There are direct spraying and exterior wall compound when hard-foam polyurethane is applied in exterior wall, roof insulation at present, but find by a large amount of construction experiences, humidity is bigger to the polyurethane heat insulation material influence, when basic unit's body of wall moisture content is high, basic unit's body of wall is relatively poor with the composite effect of the poly-propylhomoserin that hard bubbles, and easily delamination influences heat insulation effect in the use, dealing with improperly of insulation layer outer boundary makes that also heat insulation effect does not reach desired level in addition.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of environment-friendly insulating exterior wall is provided, and simple and reasonable, heat insulation effect is better, long service life.
The technical scheme that the utility model is adopted for achieving the above object is: the environment-friendly insulating exterior wall, the moistureproof prime coat of the even brushing polyurethane of basic unit's body of wall upper surface, the moistureproof prime coat upper surface of poly-propylhomoserin evenly sprays the hard-foam polyurethane insulation layer, hard-foam polyurethane insulation layer interface even brushing polyurethane interface screed, the even daub powder of polyurethane interface screed upper surface polyphenylene granule heat-insulating layer, adhesive polystyrene granule heat-insulating layer upper surface application exterior trim layer.
Described insulation layer hard-foam polyurethane density 35-40kg/m
3
Described basic unit body of wall is masonry wall or concrete wall.
Described exterior trim layer adopts coatings decoration layer, face brick decorative layer or dry-hang stone decorative layer.
Described exterior trim layer adopts the coatings decoration layer, smears the anticracking grout layer on the adhesive polystyrene granule heat-insulating layer, press-fits alkaline-resisting screen cloth in the anticracking grout layer, blade coating putty layer on the anticracking grout layer, brushing paint layer on the putty layer.
Described exterior trim layer adopts the face brick decorative layer, anticracking grout layer on the adhesive polystyrene granule heat-insulating layer, in the anticracking grout layer galvanized electric welded mesh is installed, binding face tile layer on the anticracking grout layer, galvanized electric welded mesh is by the two-way spacing 500mm anchor connection of plastics crab-bolt exterior trim surface layer and basic unit's body of wall.
On the moistureproof priming paint of the even brushing polyurethane of the utility model basic unit body of wall, eliminate water and moisture, not only effectively improve the moisture content of basic unit's body of wall, moisture vapor transmission in the use after preventing to construct, and the compactness of enhancing basic unit body of wall, cleannes, hard-foam polyurethane directly is sprayed at foaming on the moistureproof prime coat of surface of wall, because fluid mix has flowability, permeability, can enter in the basic unit body of wall space and foam, bonding securely and play the effect of sealed airspace with the basic unit body of wall, its adhesion strength surpasses the tearing strength of hard-foam polyurethane itself, thereby make hard-foam polyurethane layer and basic unit's body of wall bonding tightr, delamination does not take place, increase the service life, on the interface, adopt screed and the sealing of adhesive polystyrene granule heat-insulating layer, strengthen heat insulation effect.
Control hard-foam polyurethane layer density, with firm bonding of basic unit and play the effect of sealed airspace, hard-foam polyurethane water resistance and continuous no seam have guaranteed the integral waterproofing performance of whole heat insulation system, so good water-proof effect, water absorption rate is low, and can be because of the moisture absorption does not increase coefficient of thermal conductivity, water resistance is reliable, realizes that thermal-insulating waterproof is integrated.
Whole insulation layer does not have seam, has globality, compare with organic insulation materials such as polystyrene, the ageing-resistant performance of polyurethane is excellent more, stable chemical performance, the temperature range of anti-aging intensity is big, the not embrittlement under low temperature condition of hard-foam polyurethane body, under high-temperature condition, do not trickle, adhesion, can normally use, and chemical substances such as weak acid resistant, weak base corrode longer service life.Simultaneously, hard polyurethane foams can reach national flame-retardant standard B2 level under the effect of suitable fire retardant, do not occur the melt substance drip phenomenon in the burning, is more suitable for the requirement of existing building thermal insulation material.
The utility model body of wall has been eliminated common quality defects such as body of wall is cold thoroughly, seepage, sound insulation effectively.Be applicable to that multilayer that Winter protection, summer are heat insulation and highrise building, public building, old building energy-saving renovation engineering, building energy conservation require the outer heat insulating work greater than 65%.And constructing operation is easy.
