Abstract

The utility model relates to coated glass with layers, which belongs to the field of glass finishing. The coated glass with layers are made of two or more than two single panes, and between two adjacent single panes is a PVB layer or a SGP layer. At least one side of a single pane is coated with a radiation-protecting film. Integrating the advantages of coated glass and sandwich glass, the utility model has a general thickness of about 50mm. With a higher safety performance and with the sandwiched glass coated on an outer curving surface, the coated glass provided hereby is more energy-saving and more environmentally-friendly.

Description

The interlayer coated glass

Technical field

The utility model relates to glass processing, particularly relates to a kind of interlayer coated glass.

Background technology

Laminated glass is by tough and tensile polyvinyl butyral acetal (PVB) film two sheet glass to be bonded to an integral body under certain temperature and pressure.It can be made by annealed glass, toughened glass or hot-reinforced glass.When laminated glass was broken, glass fragment was bonded on the plastic interlayer.Therefore, laminated glass can reduce the injury of glass fragment to the person and property.Laminated glass not only can be protected the person and property safety but also keep the attractive in appearance transparent of glass.Therefore, it is unique multiduty glassy product, and in addition, it also can reduce noise, control sunlight and the harmful ultraviolet ray that masks at least 99%.

Glass is important material of construction, and along with to the improving constantly of decorating building requirement, the usage quantity of glass in building trade also constantly increases.Yet current people except considering its aesthetics and external appearance characteristic, more pay attention to its heat control, refrigeration cost and inner sunlight and throw problems such as comfortable balance when selecting the glass door and window of buildings.This just make in the coated glass family the upstart--Low-E glass is shown one's talent, become the focus that people pay close attention to.

Low-E glass claims low emissivity glass again, is that the province of English LowEmmissivity is write, and is that to plate the film that multiple layer metal or other compounds form at glass surface be product.Its coatings has and sees through and the characteristic of the high reflection of centering far infrared rays visible light is high, and it is compared with simple glass and traditional coated glass for building, has following clear superiority:

1, You Yi thermal characteristics.The thermosteresis of outer windowpane is the major portion of building energy consumption, accounts for more than 50% of building energy consumption.Relevant research data shows that the heat transfer of interior surfaces of glass accounts for 58% based on radiation, this means the loss that will reduce heat energy from the performance that changes glass, and effective means is the radiation that suppresses its internal surface.The radiant ratio of common float glass is up to 0.84, and after plating the low radiation film of one deck based on silver, its radiant ratio can be reduced to below 0.1.Therefore, make building window, can reduce the indoor heat energy that causes because of radiation greatly, reach the ideal energy-saving effect to outdoor transmission with Low-E glass.Another remarkable benefit that reduction brought of indoor calorific loss is environmental protection.Cold season is because of the discharge of harmful gases such as CO2, SO2 that constructure heating caused are important pollution sources.If use Low-E glass,, thereby reduce discharge of harmful gases because the reduction of thermosteresis can significantly reduce the fuel that consumes because of heating.

2, good optical performance.Low-E glass has high transmittance to visible light in the sunlight, can reach more than 80%, and reflectivity is then very low, and this makes it compare with traditional coated glass, and optical property is greatly taken on a new look.Watch from outdoor, outward appearance is more transparent, clear, has promptly guaranteed the daylighting that buildings is good, and the light pollution phenomenon of having avoided large-area glass curtain wall, double glazing door and window luminous reflectance in the past to be caused is again built more soft, comfortable luminous environment.

The above-mentioned characteristic of Low-E glass makes it obtain increasingly extensive application in developed country.China is the deficient relatively country of an energy, and the occupancy volume per person of the energy is very low, and building energy consumption has accounted for about 27.5% of national total energy consumption.Therefore, develop the production technology of Low-E glass energetically and promote its Application Areas, will bring remarkable social benefit and economic benefit.

As above-mentioned two kinds of glass processing technology are combined, make the interlayer coated glass, will be a be suitable for applying most safer, the building products of energy-conserving and environment-protective more.

Summary of the invention

At the blank in the above-mentioned field, the utility model provides a kind of interlayer coated glass, and its safety performance is very high, and energy-conserving and environment-protective.

The interlayer coated glass comprises the monolithic glass more than two or two that bonds together, and accompanies one deck PVB film or SGP film between the adjacent monolithic glass, and it is characterized in that: the one side of a slice monolithic glass is coated with radiation prevention film at least.

Described monolithic glass has three, and the centre accompanies two-layer PVB film.

The thickness of described monolithic glass is 8-20mm.

The thickness of described PVB film or SGP film is 1-2mm.

Described glass is toughened glass.

Described glass is bend glass.

Described radiation prevention film is positioned on the positive camber of intermediate glass.

The utility model combines laminated glass and coated glass, obtains a kind of interlayer coated glass, has kept both advantages, has more improved its effect in energy saving and environmental protection simultaneously.Between two sheet glass, press from both sides PVB or SGP film after glass can being plated radiation prevention film, form the interlayer coated glass.Accompany two-layer PVB or SGP film in the utility model in preferred three sheet glass, thickness of glass is 8-20mm, and employing curved tempered glass, the thickness of PVB glue is 1-2mm, total thickness reaches more than the 50mm, make that the security of glass is higher, and the energy-conserving and environment-protective performance is good, applicable to the outer decoration for vertical face of buildings.

Preferably, radiation prevention film of the present utility model is plated on the positive camber of intermediate glass, and test result shows, and is better than the energy-saving effect that is plated on other glass-board surface.

The utility model has organically combined the advantage of coated glass and laminated glass, and its general thickness reaches more than the 50mm, and its safety performance is higher, and the mode of intermediate glass positive camber plated film makes that the utility model interlayer coated glass energy-conserving and environment-protective performance is better.
