Description
Technical field
The utility model relates to a kind of modified polyurethane thermal insulating composite panel, belongs to wall External Thermal Insulation field of material technology.
Background technology
Building energy consumption is the emphasis that China pays close attention to always, energy-saving and emission-reduction have been the fundamental state policies that China focuses on, China is as energy consumption big country, since the later stage eighties in last century, progressively implement three energy conservation steps of energy-conservation 30%, 50% and 65%, and start the Beneficial launching the enforcement of higher energy-saving index in city with good conditionsi.Along with the progressively enforcement (Beijing has started the target performing energy-conservation 75%) of energy-conservation 65% target of domestic construction, polyurethane, as the heat insulating material with long-range prospect, captures leading position by progressively heat insulating material market at home.
But the Rigid foam polyurethane existed in the market is generally polyurethane uses interfacial agents to carry out bonding with mortar.The weatherability that there is composite plate is not good, come off after weatherability after a while or ftracture, the phenomenon such as distortion, the safety of External Thermal Insulation Composite Systems brings hidden danger.And the combination property of conventional polyurethanes and production efficiency are not enough to meet the market demand day by day increased.
Summary of the invention
The purpose of this utility model is the weak point solving the existence of above-mentioned technology, provides a kind of good combination property and a kind of modified polyurethane thermal insulating composite panel good with overlay coating adhesive property.
The utility model is achieved through the following technical solutions:
A kind of modified polyurethane thermal insulating composite panel, the cement-based back lining for external overcoat that the Chopped Strand Mat comprising poly-isocyanurate core insulation layer and interpolation polymer mortar is composited, cement-based back lining for external overcoat is arranged on poly-isocyanurate core insulation layer tow sides, be provided with several poly-isocyanurate foaming holes in poly-isocyanurate core insulation layer, poly-isocyanurate foaming hole foaming process produces self bonding performance and cement-based back lining for external overcoat is compounded in poly-isocyanurate core insulation layer tow sides.
Preferably, described modified polyurethane core insulation layer is poly-isocyanurate warming plate.
Preferably, in poly-isocyanurate core insulation layer, arbitrary neighborhood two poly-isocyanurate foaming holes offset.
In the utility model, described modified polyurethane core insulation layer is poly-isocyanurate warming plate, than common polyurethane thermal insulation board, there is higher anti-flammability and dimensional stability, water absorption rate etc., the performance of poly-isocyanurate is also applicable to the production carrying out two-forty simultaneously, significantly can improve speed of production.
In the utility model, described cement-based back lining for external overcoat carries out compound by the self bonding performance produced during poly-isocyanurate foaming, improve the adhesive strength of cement-based back lining for external overcoat and poly-isocyanurate core, overcome coming off of poly-isocyanurate core and common backing overcoat and cause the distortion of external wall system, drop.Simultaneously with the principle that the cement-based back lining for external overcoat of polymer mortar is dissolved each other by the same sex, stronger adhesive property can be produced with bonding adhesive, substantially exceed the technical requirements in national standard, also eliminate interface processing loaded down with trivial details in work progress.
The utility model has the characteristic of high flame retardant, low water suction, and heat insulating effect is good, novel in design, and the mode of production is quick, and production efficiency is high, and construction and installation are simple and convenient.The utility model adopts and utilizes the foaming of poly-isocyanurate foaming hole to produce self bonding performance compound and cement-based back lining for external overcoat compound, and have good weatherability, anti-flammability is high, high comprehensive performance.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram that the utility model proposes a kind of modified polyurethane thermal insulating composite panel.
In figure: 1, cement-based back lining for external overcoat, 2, poly-isocyanurate core insulation layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, Fig. 1 is the cross section structure schematic diagram that the utility model proposes a kind of modified polyurethane thermal insulating composite panel.
With reference to Fig. 1, a kind of modified polyurethane thermal insulating composite panel, comprise poly-isocyanurate core insulation layer 2 and cement-based back lining for external overcoat 1, cement-based back lining for external overcoat 1 is arranged on poly-isocyanurate core insulation layer 2 tow sides, be provided with several poly-isocyanurate foaming holes in poly-isocyanurate core insulation layer 2, poly-isocyanurate foaming hole foaming process produces self bonding performance and cement-based back lining for external overcoat 1 is compounded in poly-isocyanurate core insulation layer 2 tow sides.
Wherein, described cement-based back lining for external overcoat 1 is that the Chopped Strand Mat for adding polymer mortar is composited, and adhesive property is strong.Described poly-isocyanurate core insulation layer 2 is high flame retardant, low water suction, heat insulating effect is good, production efficiency is high poly-isocyanurate warming plate.
The self bonding performance that the utility model is produced in foaming process by poly-isocyanurate foaming hole, is firmly bonded in poly-isocyanurate core insulation layer 2 tow sides by cement-based back lining for external overcoat 1.The principle that the cement-based back lining for external overcoat 1 adding polymer mortar utilizes the same sex to dissolve each other, can carry out well bonding with the bonding adhesive that poly-isocyanurate foaming hole produces, avoid sheet material because weatherability generation sheet material comes off, also eliminate interface processing loaded down with trivial details in work progress, shorten construction period.Meanwhile, because the ingredient of cement-based back lining for external overcoat 1 is all inorganic material, at the scene in installation process, avoid because the electric welding that electric welding field produces uses up to fall to causing fire.Substantially increase safety and the durability of product.Poly-isocyanurate core insulation layer 2 adopt poly-isocyanurate warming plate belongs to high flame retardant, low water suction, heat insulating effect is good, production efficiency is high.Not only can meet the requirement of the building energy conservation 65% of country at present.And also can meet 75% even higher national requirements in future.
Above-mentioned enforcement is only limitted to the utility model is described, raw material wherein and production technology all can change to some extent, and every equivalent or improvement carried out on the basis of technical solutions of the utility model, all should not get rid of outside protection domain of the present utility model.
