Specific embodiment
Embodiment of the present invention is described in detail below in conjunction with embodiment, but those skilled in the art will
Understand, the following example is merely to illustrate the present invention, and is not construed as limiting the scope of the invention.It is not specified in embodiment specific
Condition person, the condition suggested according to normal condition or manufacturer carry out.Reagents or instruments used without specified manufacturer is
The conventional products that can be obtained by commercially available purchase.
According to an aspect of the invention, there is provided a kind of composite aerogel glass, including the first glass plate, the second glass
The gentle gel element of plate, packaging part.
Aeroge component is the critical component that insulation is played in the composite aerogel glass.One kind as the present invention
Embodiment, aeroge component are silica aerogel, silicon dioxide aerogel plate or silica aerogel particles
In one kind.
The film like structures that silica aerogel is formed for silica aerogel particles, aerosil
Plate is the platy structure that silica aerogel particles are formed, and silica aerogel particles are transparent for regular or irregular shape
Particle.
Since the porosity of aerosil is up to 99.8%, and pore-size is only 10-100nm, and specific surface can
Up to 1200m2/ g, these characteristics impart aerosil ultra-low thermal conductivity, low-density, the in a low voice high grade of transparency, speed etc.
Advantage, so that aeroge component also has relatively low thermal conductivity factor.In the present invention, the thermal conductivity factor of aeroge component is
0.002-0.016W/m·K。
The typical but non-limiting thermal conductivity factor of aeroge component is 0.002W/mK, 0.004W/mK, 0.005W/
MK, 0.006W/mK, 0.008W/mK, 0.010W/mK, 0.012W/mK, 0.014W/mK or 0.016W/m
K。
And the low-density due to aerosil in itself, the weight of glass will not be increased substantially, applied convenient for assembling
Work.
The size of first glass plate and the second glass plate is identical, and the two is plate glass.First glass plate and second
The type of the first glass plate of glass plate and the second glass plate may be the same or different.
As a kind of preferred embodiment of the present invention, the first glass plate and the second glass plate are separately selected from tempering
One kind in glass, wire glass or coated glass.
First glass plate and the second glass plate are arranged in parallel relatively.The distance between first glass plate and the second glass plate
It is not particularly limited in the present invention, it is general excellent for 1mm-80mm.Packaging part is located at the first glass plate and the second glass plate edge
Treat sealing-in position, packaging part is connected respectively with the first glass plate and the second glass plate, and by the first glass plate and the second glass
Plate, which encloses, is set as a cavity volume, and the main function of packaging part is exactly to enclose the gap between the first glass plate and the second glass plate to be set as using
In cavity volume, aeroge component is then located in cavity volume.
Bleeding point is additionally provided on packaging part, by bleeding point can by cavity volume vacuum state, packaging part bleeding point
Surrounding is coated with sealing layer.
Glass assembly is placed in vacuum environment and vacuumizes side heating below by sealing layer, when heating temperature reaches the molten of sealing layer
When melting temperature, sealing layer is in molten condition.It is flowed due to holding intracavity gas by bleeding point outside cavity volume, so as to drive pumping
Sealing layer around mouthful is gradually flowed to bleeding point so that bleeding point is less and less until disappearing, and after cooling, sealing layer will be taken out
Gas port is shut so that cavity volume becomes the closed containing cavity with certain vacuum degree.
To realize the above process, sealing layer should be made of the thermoplastic material for having certain adhesive property, i.e., certain
Temperature conditionss under, thermoplastic material can be softened or melted into arbitrary shape, shape invariance after cooling.But need what is illustrated
It is that the temperature that is softened or melted of sealing layer cannot be too low or excessively high.It is too low to be softened or melted temperature, blocks bleeding point
Good sealing layer is softened or melted, and be easy to causeing bleeding point gap occurs, so as to cause the destruction of vacuum degree in cavity volume；Softening or
Melting temperature is excessively high, it is necessary to which higher heating temperature, energy consumption compare in carrying out vacuumizing heating process to glass assembly
Height, while may also can have a negative impact to aeroge component.
As a kind of preferred embodiment of the present invention, sealing layer is softened or melted temperature as 100-500 DEG C.Sealing layer
Thermal plastic high polymer binding agent is chosen as, further preferably thermoplastic resin binder.
The structure of packaging part can there are many, as one embodiment of the present invention, packaging part is equipped at least two
Connecting groove, packaging part are connected by connecting groove with the first glass plate and the second glass plate；
