Description
Technical field:
The utility model relates to exterior wall external insulation technology of buildings field, a kind of light heat-insulation mortar bed rigid foam polyurethane external thermal insulation system that comprises specifically, the planeness on polyurethane composite plate exterior wall outer thermal insulation system surface be can obviously improve, system weatherability and crack resistance improved.
Background technology:
At present, hard-foam polyurethane warming plate, because its coefficient of thermal conductivity is low, high insulating effect is widely used in thin plastering exterior wall exterior insulation work, is being widely used aspect old cell energy-saving transformation and newly-built Energy Conservation Green Construction.
Tall buildings is many at present, and the construction period is fast, and base course wall planeness level is uneven, and part metope can not strictly reach the requirement of heat preservation construction planeness.
The inside and outside both sides of Rigid foam polyurethane core are fire-retardant cement-based interface mat.This class mat contains cement-based interface composition, can have good interface cementitiousness with polyurethane core and with polymer mortar.But the compound rear material of fire-retardant cement-based interface mat is harder, should not polish, polishing can destroy the interface bond effect of Rigid foam polyurethane and polymer bonding mortar.Rigid foam polyurethane, in upper wall bonding process, is subject to the impact of wall leveling degree and construction precision, between adjacent composite plate plate seam, has certain planeness difference.Conventional thin plastering construction technique is to remove plate seam both sides difference in height by polishing.And Rigid foam polyurethane external surface can not be polished.Conventional thin plastering exterior wall exterior heat preserving construction technique, is used the finishing mucilage of embedded alkaline-resisting grid cloth to carry out the processing of levelling cracking resistance, and mortar average thickness only has 3-6 millimeter.After part heat insulating work is wiped one's face and processed or use visible plate seam distortion vestige after a period of time, affect building facing appearance effect.
The Rigid foam polyurethane outer heat preservation system of thin plastering technique can be subject to sizable thermal stress effect in actual use, and this effect is mainly manifested on topping.Because the thermal and insulating performance of Polyurethane Thermal Insulation Building Materials is good especially, its finishing mucilage topping temperature can be up to 80 ℃ in summer.The caused surface temperature that suddenly rains cats and dogs after lasting fine day summer changes can reach 50 ℃ more than.The high temperature in summer also can aggravate the aging of topping.Some organic binding material in topping finishing mucilage can be destroyed due to the effect of oxygen and moisture in high temperature, air.Summer body of wall through high temperature Exposure to Sunlight processus aboralis fall heavy rain and winter diurnal temperature repeated action.Cause finishing mucilage intensity to decline.Powerful thermal stress and freeze thawing circulation cause finishing mucilage topping craze and transfiguration.Deformation effect finishing effect, cracking easily causes outside rainwater to infiltrate, and then destroys basic body of wall.
Sum up the reason that Rigid foam polyurethane can not be applied mechanically EPS external insulating system for thinly plastered external wall construction technology, mainly contain following some: 1, wall leveling degree is uneven; 2, Rigid foam polyurethane surface is difficult for polishing levelling; 3, the thin finishing mucilage thinner thickness of plastering, is difficult to effective covering to Rigid foam polyurethane plate seam planeness defect; 4, Rigid foam polyurethane directly contacts with finishing mucilage with thin plastering, and hard-foam polyurethane core density is less, and flexibility is larger, and thermal insulation is good, and finishing mucilage is contrary; Materials at two layers performance difference is excessive, lacks flexible gradual change excessive; 5, outer heat preservation system external heat stress is larger, and the thin plastoring system topping of hard-foam polyurethane flexibility is poor; These defects have restricted the extensive use of Rigid foam polyurethane aspect exterior-wall heat insulation.
Utility model content:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of light heat-insulation mortar bed rigid foam polyurethane external thermal insulation system that comprises is provided, mainly solve the problem that existing Rigid foam polyurethane cannot extensive use aspect exterior-wall heat insulation.
The technical solution of the utility model is: comprise light heat-insulation mortar bed rigid foam polyurethane external thermal insulation system, its special character is, it comprises rigid foam polyurethane layer, between rigid foam polyurethane layer inner side and base course wall, there is polymer bonding mortar layer, light heat-insulation mortar bed, the alkaline-resisting grid layer of cloth of finishing mucilage composite glass fiber is established in rigid foam polyurethane layer outside successively, and fix with anchoring piece, outermost layer is finish coat.
Further, described light heat-insulation mortar bed thickness is 8-20 millimeter.
Further, described light heat-insulation mortar bed be glass bead or glue powder polyphenyl particle.
Further, described rigid foam polyurethane layer thickness is 10-120 millimeter.
Described in the utility modelly comprise light heat-insulation mortar bed rigid foam polyurethane external thermal insulation system and compared with the prior art there is following good effect: owing to spreading the light heat-insulation mortar bed of 8-20 millimeters thick at Rigid foam polyurethane layer external surface, the direct effect that can bring is:
1, appearance effect and the anti-cracking performance of rigid foam polyurethane external thermal insulation system have been improved greatly; First transition leveling layer is used light heat-insulation mortar (glass bead or glue powder polyphenyl particle); coating thickness 8-20 millimeter; can hide easily the plate seam difference in height that Rigid foam polyurethane may bring when assembled, so just without leveling that Rigid foam polyurethane plate seam is polished.Secondly, light heat-insulation mortar bed is flexibly thermal insulation material, flexible between polyurethane heat insulation material and finishing mucilage, and the cracking resistance that meets outer heat preservation system flexible gradual change is theoretical, obviously improves system anti-crack ability.Finally, light heat-insulation mortar bed being positioned at below topping, is directly connected with finishing mucilage topping, and the thermal stress that can effectively disperse topping to receive summer, in brief, has directly improved the heat capacity of topping, causes topping temperature rising amplitude to reduce;
2, light heat-insulation mortar bed use is glass bead or glue powder polyphenyl particle, and this leveling layer belongs to fireproof inorganic heat insulating material, can obviously improve the fire-fighting performance of hard bubble polyurethane exterior wall outer heat preservation system;
3, light heat-insulation mortar bed use own is exactly ripe inorganic heat insulation material, can further improve the heat-insulating property of system;
4, use light heat-insulation mortar bed after, to building foundation wall leveling degree, can relax requirement.By pasting sheet material and smearing light heat-insulation mortar bed two subsequent steps and can correct the planeness of basic body of wall;
5, because of light heat-insulation mortar bed, Rigid foam polyurethane plate is sewed with to well long-term covering power, so be not limited to the relief carving decorative surface of strong covering power during to selection coating, also be not limited to flexible true mineral varnish coating, coating is selected to use cheap flat painting, also can use other high-grade paints;
6, light heat-insulation mortar bed is a kind of topping to architecture noumenon, can protect major structure of construction, improves building life.
