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.Technical scheme
The technical scheme of polyurethane heat insulating wall of the present invention: comprise basic unit, insulation layer, leveling layer and finish coat from the inside to the outside, it is characterized in that: at base adhesive one deck polyurethane primer, plug-in one deck longitude and latitude graticule line on polyurethane primer, insulation layer is the polyurethane rigid foam plastic of in-situ spraying, and leveling layer is to be carried out levelling, smeared polymers anti-cracking mortar again or the lightweight plastering mortar is pressed into alkali resistant glass fibre open weave cloth by the lightweight plastering mortar.
Above-mentioned 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.
Polyurethane heat insulating wall of the present invention is executed the technical scheme of technology, its processing step:
A, layer body of wall are handled;
B, brushing polyurethane primer;
C, plug-in longitude and latitude graticule line;
D, coated with hard polyurethane;
E, chipping;
Polymers anti-cracking mortar is smeared in f, the levelling of usefulness lightweight plastering mortar or the lightweight plastering mortar is 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 thickness and equal the insulation layer thickness lattice, 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 heat insulating wall and construction technology have heat-insulating property excellence, short construction period, advantage that comprehensive cost is low.
