Description
Technical field
The present invention relates to glass for building purposes technical field, the hollow glass of specifically a kind of heat-insulating flame-retardant and its preparation
Method.
Background technique
In recent years, with human society science and economic sustainable development, more represent the glass trend of the aesthetics of architecture
Huge numbers of families, building are the natural lighting for building and the aesthetic feeling for increasing building using glass.The natural lighting of building is in benefit
While with visible light, ultraviolet light, infrared ray also enter interior.The shorter ultraviolet light of wavelength in sunlight is not only to furniture
It damages, while can also cause the damage of skin to human body, generate the diseases such as canceration；Infrared ray in sunlight enters the room
Cause indoor object or spacial temperature elevation, this thermogenic action be to the heating in winter it is beneficial, still, the excessive infrared ray of summer
The thermogenic action entered the room impacts the comfort level of human body.How effectively to make glass that there is heat insulating function, is suitable for the summer
Season heat-insulated demand and Winter protection demand building glass exploitation at research importance.
With increasing for skyscraper, great attention of the use of safety glass by various circles of society.In order to avoid high level
For the glass of building in broken disintegrating slag wounding event, what current skyscraper used is all glue doubling steel glass, such as existing
PVB laminated glass is the safety glass that modern architecture uses, and is real safety glass currently on the market with practical significance.
Glass fragment after the glass breakage of PVB laminated glass still firmly sticks on PVB intermediate coat, is effectively prevented glass breakage
Secondary injury accident afterwards occurs.However, common PVB laminated glass is small to the barrier of ultraviolet light and infrared solar radiation, reach
Less than the purpose of the ultraviolet and infrared ray effectively obstructed in sunray.
In the prior art, the safety glass with heat-proof quality has had a large amount of research, such as CN103011622A at present
Disclosing a kind of coated laminated glass and its manufacturing method, the preparation method of the laminated glass is the table in first layer glass
Face metal-plated membrane layer or metal oxide layer, then laminated glass is formed with polymeric film and second layer glass.Because its is heat-insulated
Mechanism is the thermal reflection of metallic diaphragm or metal oxide layer used, therefore the metallic diaphragm or metal oxide layer are to week
Surrounding environment generates light pollution；The metallic diaphragm or metal oxide layer are formed using vacuum plasma method of spray plating, are needed
Expensive equipment production；Metallic diaphragm or metal oxide layer ingress of air are rotten in order to prevent, before preparing laminated glass,
Must also close to glass edge metal layer and metal oxide layer polish off, then with polymer glue film edge sealing, technique
Complicated and equipment investment is big；Heat preservation problem of the patented technology without reference to building glass simultaneously.
In addition, as partition material common in skyscraper, the anti-flammability of glass is also mentioned suitable to heat-insulated demand
Level, and have both fire-retardant and heat-insulated glass at present and be rarely reported.
Summary of the invention
