Description
Technical field
The present invention relates to glass making techniques field, particularly a kind of preparation method of aerogel thermal insulation glass.
Background technology
Glass is that a kind of transparency, intensity and hardness are all very high, air-locked material, and glass in chemical inertness, also can not work with biology, so purposes widely in surroundings.For the glass of building in prior art, be mainly used for closing, daylighting, insulation.But in the winter of cold district, the heat insulation effect of glass is unsatisfactory, and in the summer of hot-summer and cold-winter area or hot summer and warm winter region, the effect of heat insulation of glass is also undesirable.Simultaneously along with China's rapid development of economy, the requirement of people to quality of life is more and more higher, and building doors and windows, curtain wall are increasing, result through door and window, curtain wall the proportion of exchange heat in building and outside heat exchange increasing.In order to be reduced by the exchange heat of glass door and window curtain wall, recent domestic develops many heat insulation glass, and it mainly contains three kinds by structure, the hollow glass that (1) is made up of two-layer or multilayer simple glass; (2) by the hollow glass being coated with low-radiation film coated glass and forming; (3) by the middle vacuum glass be pumped into negative pressure and formed of double-layer glass.The hollow glass that wherein heat reflection plated film or low-emission coated (low-E) glass are formed is the main product of current energy-saving glass.Heat-reflection coated glass and low radiation coated glass can stop sunshine to enter indoor in summer to greatest extent, and stop the far infrared radiation from outdoor to greatest extent.But needing the winter of heating, it is obviously outdated that the outer heat energy of air lock enters indoor, and affect the transmitance of visible ray.Vacuum glass is because of the reason such as safety and application life, and large-scale application is still needed the time.Therefore a kind of heat insulation glass with good thermal insulation and light transmission of exploitation is badly in need of.
Summary of the invention
The technical problem to be solved in the present invention is: the preparation method providing a kind of aerogel thermal insulation glass, the heat insulation glass that this preparation method produces has good thermal insulation and light transmission, can be widely used in the fields such as the door and window of green building and super low energy consumption building and nearly zero energy consumption building, cladding glass and lighting roof.
