Description
Technical field
The utility model is related to technical field of external wall heat preservation more particularly to a kind of double hot sealing layer high vacuum Obstruct membranes.
Background technology
China is energy consumption big country, and with the economic sustained and rapid development in China, building energy consumption accounts for about Chinese society total energy
The 30% of consumption, building energy conservation form is urgent.China each department climate difference is larger, and the energy-saving design in construction of different regions requires not
Together, GB50176-1993《Code for thermal design of civil buildings》It explicitly points out, the design requirement to hot summer and warm winter region is " necessary
Fully meet summer anti-heat request, can not generally consider Winter protection ", in the industry to " north is to keep the temperature, southern emphasis be every
Heat " has been built consensus.In southern area, the ratio that indoor/outdoor temperature-difference heat transfer accounts in entire heat transfer is small, what solar radiation generated
Fuel factor is the main reason for causing Summer Indoor Thermal.Insulating moulding coating can reflected solar radiation heat, to reduce indoor heat,
Air conditioner refrigerating energy consumption is effectively reduced, numerous research confirms facilitation of the insulating moulding coating to building energy conservation.
The insulation of architectural exterior-protecting construction is one of the key technology for realizing building energy conservation, the heat preservation of architectural exterior-protecting construction
Provision for thermal insulation is essentially divided into several aspects such as the mild wall self-insulation of exterior insulation, exterior wall insulating, and China is with exterior wall at present
Outside wall heat preservation is leading.The external wall heat insulation system being widely used at present has outer patch heat preservation plate thin plastering and uses vacuum heat-preserving
Plate two ways.
Although outer patch, which keeps the temperature plate thin plastering, has good heat insulation effect, there are complicated construction technique, overall costs for it
The shortcomings of high, surface material construction quality is difficult to ensure；Vacuum heat-insulation plate is easy to be punctured and produce during installation or use
Raw bulking effect, can make it lose heat-insulating property in this way.For this purpose, applicant has developed a kind of novel vacuum heat-insulating board, the application
High vacuum Obstruct membrane suitable for the vacuum heat-insulating plate.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the double heat-sealing floor heights of the one kind proposed
Vacuum screened film.
To achieve the goals above, the utility model uses following technical solution：
A kind of double hot sealing layer high vacuum Obstruct membranes, it is characterised in that：Including compound nylon layer, polyester successively from outside to inside
Aluminizer and aluminium foil layer, the hot sealing layer outside composite joint on the outside of the nylon layer, the hot sealing layer in composite joint on the outside of the aluminium foil layer.
Preferably, the outer hot sealing layer is PE films.
Preferably, the outer hot sealing layer is EVA film.
Preferably, the outer hot sealing layer is CPP films.
Preferably, the interior hot sealing layer is PE films.
The utility model has the advantage of：A kind of double hot sealing layer high vacuum Obstruct membranes provided by the utility model, it has
There are double hot sealing layers, after evacuation with the vacuum heat-insulating plate of the high vacuum Obstruct membrane, using heating, interior hot sealing layer and core can be made
Material hot-melt adhesive paste, good seal performance is anti-puncture, its heat-insulating property will not be completely lost being punctured.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of double hot sealing layer high vacuum Obstruct membranes provided by the utility model.
Specific implementation mode

210 μm, wherein：The thickness of the outer hot sealing layer 4 be 20 μm -50 μm, the present embodiment preferably use the thickness of outer hot sealing layer 4 for
25 μm, 30 μm, 35 μm, 40 μm or 45 μm, the thickness of the interior hot sealing layer 5 is 20 μm -50 μm, and the present embodiment preferably uses interior
The thickness of hot sealing layer 5 is 25 μm, 30 μm, 35 μm, 40 μm or 45 μm.
When in use, this double hot sealing layer high vacuum Obstruct membrane is fabricated to bag shaped structure, as high vacuum barrier bag, at this
Device core material in high vacuum barrier bag, obtains interior vacuum heat-insulation plate after vacuumizing, sealing, heat, in interior vacuum heat-insulation plate
Both sides are adjacent to connecting plate-shaped thermal insulation material and are loaded into barrier bag, and barrier bag uses the prior art, it is preferred to use internal layer
The barrier bag of the heat-insulated adhesive linkage of macromolecule with low melting point, again vacuumizes it and is heated to it.The application is carried
Hot-melt adhesive paste between the interior hot sealing layer 5 and core material of the high vacuum Obstruct membrane of confession, heats between outer hot sealing layer 4 and board type insulant
Connection.
