Abstract
The present invention relates to an improved thermal insulation technology for building wall and features that in the gap between the outer decoration for external wall and wall body, a liquid mixture of polyisocyanate and combined polyether in a ratio of 1.01-1.09 to 1 is injected. The liquid mixture reacts to form hard foamed polyurethane which is combined with wall body and its outer decoration, and has high waterproof, heat insulating and air isolating effects and small load on wall body.
Description
The present invention relates to the heat preserving method of building engineering field body of wall, in particular a kind of method of utilizing polyurethane foam to make wall thermal insulating.
At present, the heat preservation technology of building masonry wall is at first to adopt the splicing of benzene plate, and sieve clinging net, steel nail are fixed then, and be last, smears cement mortar, pastes outer ornament or adopts the antifreeze ceramic tile of subsides to reach heat insulation effect.Before a kind of technology have that waterproofing course destroys easily and the forfeiture waterproof ability, the heat insulating material coefficient of thermal conductivity is big, heat insulation effect is poor, the shortcoming that the body of wall load is big, a kind of method cost height in back, heat insulation effect are also undesirable.
The purpose of this invention is to provide a kind of waterproof, high insulating effect, have the trapping effect, and the little construction wall thermal insulation producing method of body of wall load, overcome the shortcoming that prior art exists.
To achieve the object of the present invention, the method that adopts is included in a kind of mixed liquor that insulation, waterproof, cementation are arranged of injection in the space between outer ornament and the wall, and wherein this mixed liquor is polyisocyanates and combined polyether in (1.01-1.09): 1 ratio mixing is stirred to the mixed liquor that occurs after the milky white rapidly.
The present invention also can adopt ornament and hard polyurethane foams composite material outside precast yard is prefabricated, and then makes heat-preserving wall according to the method described above.
The mixed liquor of polyisocyanates and combined polyether has extremely strong adhesion stress in foaming, can with any material bonding, comprise metal and nonmetal etc.According to the variation of environment temperature, can add delayed catalyst in the combined polyether, generally in 0-10 ℃ of scope, need to consider to add delayed catalyst, can obtain the foam of good quality.The method is applied to domestic balcony insulation, bathing pool insulation, freezer insulation and building exterior wall heat preserving.Hard polyurethane foams is except that having low-down coefficient of thermal conductivity, also has excellent waterproofness, no matter adopt manual batch-foamed, still adopt machinery continuous foamed, the capital forms the froth bed of integral seamless, and the foam density that especially mechanical continuous foamed method forms is even, fine quality, therefore, this method also can be used for building roof waterproof.Do the heat-preservation balcony test by the scene, the hard polyurethane foams coefficient of thermal conductivity reaches 0.023w/m.k, and under subzero 23 ℃ situation, the temperature in the hard polyurethane foams heat-preservation balcony of foam-in-place can reach subzero 2 ℃-6 ℃ above freezing, and heat insulation effect is fabulous.
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 is the structural representation after the invention process;
Fig. 2 is the structural representation of another embodiment of the present invention.
In order to improve speed of application and to consider conveniently, way of the present invention adopts mould so that a large tracts of land cast, as figure-shown in: metope 1, hard polyurethane foams 2, ceramic tile 3, template 4, sucker 5, pin 6.Hold the light face of ceramic tile 3 with sucker 5, pass the sucker hole on the template 4, make the light face contact template 4 of ceramic tile 5, the handgrip of sucker 5 is fastened on the back side of template 4 with pin 6, prevents that ceramic tile 3 strings from moving.Then, the template 4 that is filled ceramic tile 3 is stood in the wall limit, at this moment, in order to stand in the wall limit, need between ceramic tile 3 pitted skins and wall, to come levelling with vertical with making template 4 horizontal vertical, make distance between ceramic tile pitted skin and the wall at 25mm with adjustment piece, spirit level.Polyisocyanates and combined polyether are poured in the plastic cup in 1.02: 1 ratio, stirred for 10 seconds rapidly, closing liquid reaction to this elder brother occurs pouring into after the milky white in the space between template 4 and the wall, repeat repeatedly to be full of the space up to the hard polyurethane foams that generates, after treating 15 minutes, remove pin 6, remove template 4, remove each sucker 5 vacuum, sucker 5 has promptly formed heat-preserving wall with ceramic tile 3 natural separation.For fear of template and adjustment piece, ceramic tile bonding, can on template, smear removers such as lubrication oil, machine oil, butter in advance, in order to prevent that polyisocyanates and combined polyether mixed liquor from producing expansion force in foaming, so that make ceramic tile fracture or template moved, template with another to face wall between need head on to apply support force with long wooden stick.
With thickness is that the wooden density board of 10mm is cut out by the balcony height, sequences by balcony length, with adjusting piece adjustment and wall apart from 25mm, uses the spirit level level of corrections with vertical simultaneously, then, applies top power in the density board front, in case expansion is shifted during foaming.Polyisocyanates and combined polyether are poured in the plastic cup in 1.05: 1 ratio, stirred 12 seconds rapidly, to the space of pouring into after milky white appears in the reaction of this mixed liquor between density board and the wall, repeat repeatedly to be full of the space up to the hard polyurethane foams that generates, after treating 20 minutes, eliminate top power, promptly formed the composite thermal-insulating wall of density board and hard polyurethane foams.
Give boring on the wall earlier, utilize special expansion bolt, promptly be trapezoidal screw rod by rotating tip, thereby shape nut and wall are fixed, shown in figure two: the 1st, the top is trapezoidal screw rod, the 2nd, the shape nut, the 3rd, body of wall, the 4th, polyurethane foam, the 5th, shaving board, because outer ornaments such as shaving board are connected with screw rod, so can suitably select the fixed distance shaving board between shaving board and the wall, make the certain space of formation between shaving board and the wall, then, polyisocyanates and combined polyether are poured in the plastic cup in 1.05: 1 ratio, stirred 12 seconds rapidly, to the space of pouring into after milky white appears in this mixed liquor reaction between shaving board and the wall, repeat repeatedly to be full of the space up to the hard polyurethane foams that generates, after treating 20 minutes, promptly form the composite thermal-insulating wall of shaving board and hard polyurethane foams.
