Abstract
The present invention relates to a polyurethane thermal-insulation wall and a construction technique thereof. The construction technique comprises: a base layer wall is treated; base polyurethane paint is brushed; longitude and latitude lattice lines are suspended externally, and a small lattice of which the thickness is equal to that of the thermal-insulation layer is made on the surface of the outer wall by using a nonmetal wire or metal wire with the diameter of smaller than 1.0mm; hard polyurethane is sprayed; surface defects are trimmed; light-weight finishing mortar is used for leveling the wall, polymer crack-resistance mortar or light-weight finishing mortar is plastered and pressed in alkali-proof glass-fiber lattice cloth, and the light-weight is prepared by mixing organic high-molecular polymers and inorganic silicates used as main gelled materials with different light-weight skeletal materials with different grades; finally, flexible putty is plastered, or relievo paint is sprayed and surface layer paint is brushed. The present invention solves the technical problems that when the hard polyurethane plastic foam is sprayed on site, the surface evenness of the outer thermal-insulation wall is difficult to control, the adhesive force between the surface layer and the polyurethane hard-bubble thermal-insulation layer, and the surface layer easily cracks. The present invention has the advantages of favorable thermal-insulation performance, short construction period and low comprehensive cost.
Description
(1) technical field
The present invention relates to a kind of heat-preserving wall and job practices.
(2) background technology
In the power-saving technology of present building external envelope structure, outer heat preservation technology is not owing to take advantage such as the interior space, and its application is very extensive.Existing external heat insulating wall mainly contains the granular polystyrene slurry, pastes bodies of wall such as polyphenyl plate, on-site casting polyphenyl plate, rock cotton board, foam glass, the heat-insulating property of these bodies of wall, application property, security and stability are different, the heat insulating material coefficient of thermal conductivity that has is higher, be not suitable for the needs of the heat preservation energy-saving of severe cold area and higher energy-conservation requirement, wayward in the security and stability construction that has, the construction complexity that has, the quality control difficulty is big, and the surface layer cracking resistance problem that has is difficult to resolve determines.Also do not have at present a kind of external heat insulating wall and job practices have simultaneously good heat insulating, construction easily, the cycle is short, the surface layer effect of anti-cracking is good characteristics.RPUF is applied to the building heat preservation field, occurs with the RPUF filled board mostly at present, on-the-spot directly foaming, only be confined to waterproofing and thermal insulation of roofing.On-the-spot directly foaming RPUF is applied to the vertical body of wall of outer insulation of veneer coating layer, a main difficult problem such as have that surface finish is difficult to control, poor adhesive force, outside finish between finish coat and the RPUF are easy to crack.
(3) summary of the invention
The present invention will solve that in-situ spraying RPUF external heat insulating wall surface finish is difficult to control, poor adhesive force, surface layer technical barrier easy to crack between surface layer and the hard polyurethane foam insulation layer.
The technical scheme of polyurethane external heat insulation body of wall of the present invention, it is characterized in that: at body of wall basic unit brushing one deck polyurethane primer, plug-in one deck longitude and latitude graticule line on polyurethane primer, in-situ spraying polyurethane rigid foam plastic insulation layer in the longitude and latitude graticule line, insulation layer is outward that lightweight plastering mortar leveling layer, leveling layer are smeared polymers anti-cracking mortar outward again, and being pressed into alkali resistant glass fibre open weave cloth, finish coat is flexible waterproof putty, planomural shape coating or textured coating.
The line of above-mentioned plug-in longitude and latitude graticule line footpath is less than 1.0mm, and the distance of it and body of wall equals insulation layer thickness.
The lattice of above-mentioned plug-in longitude and latitude graticule line is square or the rectangle of the length of side less than 1m.
Above-mentioned plug-in longitude and latitude graticule line is non-metal wire or wire.
The job practices of this polyurethane external heat insulation body of wall is characterized in that processing step is as follows:
A, basic unit's body of wall are handled;
B, brushing polyurethane primer;
C, plug-in longitude and latitude graticule line;
D, coated with hard polyurethane foam plastic, thermal-insulation layer;
E, chipping;
F, the levelling of usefulness lightweight plastering mortar are smeared polymers anti-cracking mortar and are pressed into alkali resistant glass fibre open weave cloth;
G, scrape flexible putty or spray textured coating, brushed surface coating.
Above-mentioned c step be at exterior wall surface with line footpath less than the non-metal wire of 1.0mm or wire is vertical through hanging, cover side, bullet control line, make the lattice that thickness equals insulation layer thickness, lattice is square or the rectangle of the length of side less than 1m.
The lightweight plastering mortar of above-mentioned f step is that organic high molecular polymer and inorganic silicate are made main cementitious material, forms with the aglite mixed preparing of different gradation.
Above-mentioned aglite is the mixture of caoutchouc elasticity particle, granular polystyrene, expanded vermiculite, expanded perlite, float stone, broken gas concrete quarrel or above-mentioned aglite.
Beneficial effect:
1. adopt the insulation layer material of RPUF as external wall outer insulation, it is little to have coefficient of thermal conductivity, the heat-insulating property excellence, water-fast, cold-resistant heat, acidproof, alkaline-resisting, the chemical-resistance product are good, are fit to the heat preservation energy-saving of severe cold area and the needs of higher energy-conservation requirement.
2. pass through at the plug-in longitude and latitude graticule line of vertical wall, the unmanageable technical barrier of surface finish when having solved the coated with hard polyurethane foam plastics, and be convenient to check and accept.
3. adopt the on-the-spot airless spraying RPUF of high pressure airless spraying apparatus, operation pressure is not less than 100kg/cm
2, the material temperature is constant about 25 ℃, and the combination material mixes by high-pressure vaporization, foam-in-place on building wall, one-shot forming, whole being molded over about 1～5 minute finished, and solidifies can enter next working procedure after 0.5 hour.Characteristics such as have that speed of application is fast, stable molding, compliance are strong.
4. the levelling of lightweight plastering mortar is adopted in the levelling of RPUF surface layer cracking resistance, be pressed into alkali resistant glass fibre open weave cloth with polymers anti-cracking mortar or lightweight plastering mortar again, integrate levelling, cracking resistance, construction easily, once plastering can reach more than the 2cm, and anti-crack ability is strong.
5. the lightweight plastering mortar adopts organic high molecular polymer and inorganic silicate to make main cementitious material, by forming with the aglite of different gradation is composite, solve surface layer mortar and the bad problem of RPUF insulation layer adhesive power effectively, can prevent the cracking of surface layer simultaneously.6. putty layer adopts the outer wall flexible water proof putty, can prevent the putty layer cracking and decoration, the protection effect of influence surface coating.
Polyurethane external heat insulation body of wall and job practices have heat-insulating property excellence, short construction period, advantage that comprehensive cost is low.
