Description
Technical field
The present invention relates to a kind of aeroge energy-saving glass, are substituted for existing simple glass.
Technical background
Aerogel material, because of its excellent property, increasingly causes people from being born till now less than the centenary time
Attention, application is also more and more extensive.The microstructure of aeroge is a kind of nano level microcellular structure, is that one kind is more
Hole, low-density, non-crystalline material have continuous tridimensional network.The porosity can reach more than 90%, and specific surface area can be with
Up to 1000m2/ g, this so that the density of aeroge is very low, can reach 10Kg/m3Below.Therefore, aeroge is in mechanics, light
It learns, calorifics, there is important application value in the fields such as electricity.The wherein most interestingly excellent adiabatic heat-insulation energy of aeroge
Power, unique nanoporous structure make the thermal conductivity of material extremely low, are the best solid materials of current insulation capacity.
The aeroge glass made using aeroge compared with traditional glass, has excellent adiabatic heat-insulation ability, summer can
Heat is effectively reduced to indoor transmission speed, winter can effectively ensure that indoor temperature.At present, the unit energy of China's building field
The developed countries such as the far super America and Europe of consumption, occupy key factor in AND ENERGY RESOURCES CONSUMPTION IN CHINA.13 planning, clearly receive building energy conservation
Enter in planned range.Among these with winter and summer energy consumption highest.In winter, outdoor temperature is relatively low, and a large amount of heat is from indoor stream
To outdoor, among these, sizable a part of heat makes what is be lost at door and window.Summer, outdoor temperature are high, and heat is to interior
It is also greatly to be flowed at door and window in transmittance process.Energy-saving glass is broadly divided into two major class at present, and one kind is hollow glass
Glass by sandwich establishment in glass, reduces the mode of interlayer vacuum-pumping the thermal conductivity of glass, realizes heat preservation energy-saving.It is another
Kind is realized by pasting infrared reflection film, and the mechanism of heat insulation of this kind of glass is mainly infrared by reflecting, while itself
Thermal conductivity factor is relatively low, so as to fulfill heat preservation energy-saving.But its insulating power is simultaneously bad, and cost is higher.
Current existing aeroge glass is prepared by supercritical drying, and complex process is of high cost, and the present invention makes
Constant pressure and dry, simple process and low cost, aeroge glass heat-insulating ability are very good.
