Description
Technical field
The present invention relates to heat preservation technology field, more particularly to a kind of efficient inorganic vacuum heat-insulating plate.
Background technology
The insulation of architectural exterior-protecting construction is one of the key technology for realizing building energy conservation, the insulation of architectural exterior-protecting construction
Provision for thermal insulation is essentially divided into several aspects such as the gentle wall self-insulation of external wall outer insulation, exterior wall insulating, and wall heat insulation material is not
But can play a part of to protect wall agent structure, while reducing the shadow of ambient temperature, humidity and various rays to agent structure
Ring.Current China is leading with External Thermal Insulation Technology for External, and wide variety of external wall heat insulation system has outer patch to be incubated plate thin plastering
With using vacuum heat-insulation plate two ways, although the former is with good heat insulation effect, there is complicated construction technique, synthesis in it
The shortcomings of high cost, surface material construction quality are difficult to ensure that, the latter is made by the low high molecular foam material of thermal conductivity factor
There is vacuum reduction in core, housing material, getter and adsorbent composition, this warming plate, heat-insulated after long-term use
The shortcomings of heat insulation effect has much room for improvement, and existing warming plate, after barrier bag breakage, core plate easily expands so that warming plate still loses
The performance of heat-insulation and heat-preservation, and the warming plate for being used at this stage not only thickness is larger, and thermal conductivity factor is larger, and using effect is not
It is highly desirable.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of efficient inorganic vacuum for proposing is exhausted
Hot plate.
To achieve these goals, present invention employs following technical scheme：
A kind of efficient inorganic vacuum heat-insulating plate, it is characterised in that：Including core plate, interior barrier bag is wrapped up in core plate outer side seal,
Interior barrier bag outer side seal wraps up outer barrier bag, getter is provided between core plate and barrier bag, in interior barrier bag and outer obstruct
Transition vacuum layer is filled between bag.
Preferably, the block of glass wool that the core plate is made using super glass wool through wet method.
Preferably, the aperture of the core plate is less than 5 μm.
Preferably, the material of the interior barrier bag is the trapping film that layer high molecule material film is composited, and it is wrapped
Include nylon, polyester, polyvinylidene chloride and ethylene-vinyl alcohol copolymer.
Preferably, the compound trapping film of the material multilayer macromolecule material film of the outer barrier bag it include nylon,
Polyester, polyvinylidene chloride and ethylene-vinyl alcohol copolymer.
Preferably, PVDC, PVA, SiO are also coated in the outside of the outer barrier bagXOr Al2O3。
Preferably, the transition vacuum layer is the mixture of getter and adsorbent.
The advantage of the invention is that：This vacuum heat-insulating plate uses two-layer barrier bag, is vacuumized twice, forms secondary true
Altitude, reduces the speed of gas permeation, and stable performance, heat-insulating property reliability, thermal resistance is big, and vacuum is high, and thermal conductivity factor is low, the longevity
Life length, with good heat insulating effect, is not influenceed with expanding with heat and contract with cold, it is adaptable to mass produce by temperature.
Brief description of the drawings
Fig. 1 is a kind of structural representation of efficient inorganic vacuum heat-insulating plate provided by the present invention.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, a kind of efficient inorganic vacuum heat-insulating plate that the present invention is provided, including core plate 1, it is close in the outside of core plate 1
Package wraps up in interior barrier bag 2, and outer barrier bag 4 is wrapped up in the outer side seal of interior barrier bag 2, is also coated in the outside of the outer barrier bag 4
PVDC、PVA、SiOXOr Al2O3.Getter 5 is provided between core plate 1 and barrier bag 2, interior barrier bag 2 and outer barrier bag 4 it
Between fill transition vacuum layer 3, transition vacuum layer 3 is the mixture of getter and adsorbent, and the effect of getter is to maintain thermal insulation
Vacuum in plate.Because in process of production, during sealed after being vacuumized, having a small amount of air and entering in heat-insulating shield, heat-insulating shield
In use, also have a small amount of gas infiltration trapping film to enter in heat-insulating shield, the core of heat-insulating shield can also discharge one
A little gases, such as vapor.
The block of glass wool that the core plate 1 is made using super glass wool through wet method, the aperture of core plate 1 is less than 5 μm, gas
Will not be collided between molecule, there is no heat exchange, also just without heat loss, thermal conductivity factor diminishes.Core plate 1 has certain pressure resistance
Degree, it is to avoid contraction distortion under vacuum, its secondary prevention radiation of heat, and its contact surface is small, heat transfer is low.
The material of the interior barrier bag 2 is the trapping film that is composited of layer high molecule material film, it include nylon,
Polyester, polyvinylidene chloride and ethylene-vinyl alcohol copolymer.For surface trapping film, be important to concern vapor and
The infiltration rate of oxygen, while also requiring that with certain mechanical strength, rigidity and heat resistance.
The compound trapping film of the material multilayer macromolecule material film of the outer barrier bag 4 it include nylon, polyester, poly-
Vinylidene chloride and ethylene-vinyl alcohol copolymer.Its Main Function provides a transition vacuum environment, it is to avoid gas directly by
Air leaks into vacuum insulation intralamellar part, can reduce gas permeation, improves the performance of vacuum heat-insulating plate.
The heat-insulating shield of this programme forms secondary vacuum environment, and such core material of vacuum heat insulation plate part is once to vacuumize ring
Border, barrier bag outer layer re-forms a vacuum environment, and the air of the outside leaked into vacuum heat-insulating plate is needed by transition vacuum
Layer 3 can be leaked into inside sheet material, can effectively reduce the speed of gas permeation, extend the life-span of sheet material.
Using the inorganic vacuum heat insulation materials technology of multifunctional efficient, it is assumed that intralamellar part vacuum is 10Pa, is P1；Transition zone
Initial depression is 20Pa, is P12, and the vacuum of transition zone is P2 after 15 years, and the leak rate of actual measurement group barrier film is。
For one block of VIP plate of 45 × 28 × 2.5cm, its volume V is 3.15 liters, then：
Calculated more than, transition zone vacuum is 144.6Pa after 15 years.
It follows that the vacuum heat-insulating plate leak rate with transition zone is, much smaller than actual measurement group barrier film
Leak rate, leak rate reduces two orders of magnitude, and this is because transition zone effectively reduces evacuated panel
Internal pressure difference.Leak rate reduces 107.9 times, then barrier property is greatly improved.
