Description
Technical field
The present invention relates to a kind of building energy conservation glass and manufacture method thereof, be specifically related to a kind of sandwiched heat-insulating safety glass and manufacture method thereof.
Background technology
In recent years, along with human society science and economic sustainable development, the glass that represent the aesthetics of architecture moves towards huge numbers of families more, and building adopts glass to be the aesthetic feeling that the natural lighting in order to build is built with increase.The natural lighting of building is while utilizing visible ray, and ultraviolet, infrared ray also enter indoor.The shorter ultraviolet of wavelength in sunshine not only damages furniture, also can cause the damage of skin, produce the diseases such as canceration human body simultaneously; Infrared ray in sunshine enters indoor and causes indoor object or spacial temperature elevation, and the heating of this thermogenic action to winter is useful, but the excessive infrared ray in summer enters indoor thermogenic action, impacts the comfort level of human body.Glass accounts for 30 ~ 70% of building envelope area, in architectural exterior-protecting construction, the heat transfer coefficient of glass is little compared with body of wall, so, winter is greater than body of wall by the heat loss of glass, import indoor heat into by glass summer and be also greater than body of wall, the whole year exceedes exterior wall by the energy consumption of glass, and great majority account for more than 40% of building total energy consumption.Therefore, there is the heat insulation functional requirement becoming building glass with the energy-saving glass of Winter protection in summer.Along with increasing of skyscraper, the use of safety glass is subject to the great attention of various circles of society.China geographical position is severe cold area, cold district, hot-summer and cold-winter area, hot summer and warm winter region according to climatic classification, and each department require it is different to the thermal characteristics of building glass.How effectively to make glass not only have heat insulating function, but also have heat insulation function, be applicable to summer heat insulation demand and Winter protection demand building glass be developed to the importance of research.
The patent document of report insulating mold coating of transparent glass and prepared transparent heat insulating glass is a lot, and its technology is quite ripe, and transparent heat insulating glass application is also very extensive.Such as, CN1232599C discloses a kind of nano transparent heat-insulation composite coating, and employing fluoropolymer resin is film forming matter, ITO, ATO are the transparent heat insulating dope of insulation medium.Owing to being the heat-protecting glass being coated with insulating moulding coating formation on the basis of monolithic glass, its energy saving does not change substantially, and the improvement of its heat insulating ability is limited.
Existing PVB laminated glass is the safety glass that modern architecture uses, and is the real safety glass in the market with practical significance.Glass fragment after the glass breakage of PVB laminated glass still sticks on PVB intermediate coat firmly, effectively prevents the secondary injury accident after glass breakage from occurring.But the common obstruct of PVB laminated glass to ultraviolet and infrared solar radiation is little, does not reach and effectively intercept ultraviolet in sunray and ultrared object.
The safety glass with heat-proof quality has had large quantifier elimination at present, as CN103011622A discloses a kind of coated laminated glass and manufacture method thereof, the preparation method of described laminated glass is, at ground floor interior surfaces of glass metal-plated membrane layer or metal oxide layer, then form laminated glass with polymeric film and second layer glass.Because of the heat reflection effect that its insulating mechanism is metallic diaphragm used or metal oxide layer, therefore this metallic diaphragm or metal oxide layer produce light pollution to surrounding enviroment; This metallic diaphragm or metal oxide layer adopt vacuum plasma method of spray plating to be formed, and needs expensive device fabrication; In order to prevent metallic diaphragm or metal oxide layer ingress of air from going bad, before preparing laminated glass, also must polish off near the metal level of glass edge and metal oxide layer, then using polymer glued membrane edge sealing, its complex process and equipment investment large; This patented technology does not relate to the insulation problem of building glass simultaneously.
