Abstract

The utility model relates to low-emissivity coated glass which comprises a glass substrate and at least a coating layer arranged on the glass substrate, wherein the coating layer is composed of silver, copper and tin or the compounds of silver, copper and tin. The low-emissivity coated glass has good heat preservation performance and effectively controls solar energy radiation, blocks far infraredray radiation so that the air-conditioning charge in summer is saved and the heating charge is saved in winter, the optical projection ratio is higher and the reflection ratio is low, the light pollution is effectively avoided, the furniture and textile are prevented from dyeing; meanwhile, the low-emissivity coated glass has wide light spectrum selection range and rich color.

Description

Low radiation coated glass

Technical field:

The utility model relates to a kind of glass, particularly a kind of low radiation coated glass.

Background technology:

Existing conventional clear glass is used very extensive, its transmission range just in time overlaps with the solar radiation SPECTRAL REGION, therefore, when seeing through visible light, infrared heat energy in the sunlight also can see through glass in a large number, and the heat energy of 3～5um middle-infrared band is by a large amount of absorptions, thermal radiation more than the wavelength 5um that heating installation is sent, simple glass can not directly see through but be close to fully and absorb, and by conduction, radiation reaches can be heat passage to outdoor with cross-ventilated mode, indoor temperature reduced, in addition, simple glass can not shielding of ultraviolet, easily makes indoor furniture and fabric fading.

Summary of the invention:

The purpose of this utility model is in order to overcome above deficiency, a kind of good heat-insulating property that has is provided, can effectively control solar radiation, the blocking-up far infrared radiation, cost saving has higher light projection ratio and low reflectivity, effectively avoid light pollution, can prevent furniture and fabric fading, and the spectrum range of choice is wide, color is abundant.

The purpose of this utility model is achieved through the following technical solutions: a kind of low radiation coated glass, comprise glass basis, and on glass basis, be provided with one deck coatings at least, described coatings is made up of silver, copper, tin or its compound.

The utility model compared with prior art has the following advantages: low radiation coated glass has good heat-insulating property, can effectively control solar radiation, the blocking-up far infrared radiation, save the air-conditioning expense summer, save heating cost winter, higher light projection ratio and low reflectivity are arranged, effectively avoid light pollution, can prevent furniture and fabric fading, and the spectrum range of choice is wide, color is abundant.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Number in the figure: 1-glass basis, 2-coatings.

Embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show a kind of embodiment of the utility model low radiation coated glass as Fig. 1, comprise glass basis 1, on glass basis 1, be provided with one deck coatings 2 at least, coatings 2 is made up of silver, copper, tin or its compound, can have higher reflection potential to the radiation of 2～25um wavelength region mid and far infrared, this low radiation coated glass is divided into colourless and coloured two big series, the former is used for high latitude area, its visible transmission ratio is greater than 70%, can stop that indoor thermal energy rushes down to outdoor, thereby keep room temp, save heat cost; The latter uses at low latitudes, preventing that indoor heat is to the extraradial while, has certain sunshade effect, can intercept infrared rays very doughtily, the double effects of performance natural lighting and heat-insulating and energy-saving, its visible light transmissivity height, the secondary rays after the object in summer can air lock is subjected to solar light irradiation, more energy-saving and cost-reducing.This low radiation coated glass, than monolithic simple glass energy-conservation 75%, than ordinary insulating glass energy-conservation 40%, can effectively save refrigeration expense and heat cost about 50% more, in other words, two of one cover, 100 square meters occupy, annual heating cost and air-conditioning take with 10,000 yuan of calculating, use low radiation coated glass only with 5000 yuan of costs, reach more the effect of saving, and the color of glass can be transparent, light gray, silver color, shades of colour such as light blue, bluish-green, the spectrum range of choice is wide like this, color is abundanter, and can effectively prevent indoor furniture and fabric fading.

Claims

1, a kind of low radiation coated glass comprises glass basis (1), it is characterized in that: described glass basis (1) is provided with one deck coatings (2) at least, and described coatings (2) is made up of silver, copper, tin or its compound.
