Abstract

The utility model discloses single silver LOW-E glass capable of being toughened. The single silver LOW-E glass comprises a glass substrate; and five film layers are adjacently combined on a combining surface of the glass substrate in sequence from inside to outside. The single silver LOW-E glass is characterized in that the first film layer, namely the innermost layer is a Si3N4 layer, the second layer is a TiO2 layer, the third layer is an Ag layer, the fourth layer is an NiCr layer, and the fifth layer, namely the outermost layer is a Si3N4 layer. The utility model provides the special film system single silver LOW-E glass capable of being toughened, which has the advantages of high transmittance and low radiant emittance.

Description

But tempering list silver LOW-E glass

[technical field]

The utility model relates to a kind of coated glass, but especially a kind of tempering list silver LOW-E glass.

[background technology]

Glass is the indispensable integral part of buildings and automobile, is bearing many important function, comprises the outward appearance of beautifying constructure and automobile, daylighting and give the indoor open visual field of bringing.But simple glass sunlight transmitance is general, and infrared reflectance is very low, and most of sunlight sees through glass and in the inlet chamber, thus heating object, and the energy of these indoor objects can lose by glass with forms of radiation.

For this reason, the inventor has designed this patent, to overcome the problems referred to above.

[utility model content]

The utility model has overcome the deficiency of above-mentioned technology, but provides a kind of transmitance height, radiant ratio the low two silver-colored LOW-E glass of special film system tempering.

For achieving the above object, the utility model has adopted following technical proposal:

But a kind of tempering list silver LOW-E glass includes glass substrate, is adjacent to successively from inside to outside be compounded with five retes on the composite surface of glass substrate, and it is characterized in that: wherein first rete is that innermost layer is Si ₃N ₄Layer, the second layer is TiO ₂Layer, the 3rd layer is the Ag layer, and the 4th layer is the NiCr layer, and the layer 5 outermost layer is Si ₃N ₄Layer;

The Si of described first rete ₃N ₄The thickness of layer is 17～23nm; The TiO of the described second layer ₂The thickness of layer is 20～25nm; The thickness of described trilaminar Ag layer is 8～14nm; The thickness of described the 4th layer NiCr layer is 5～10nm; The Si of described layer 5 ₃N ₄The thickness of layer is 40～50nm.

Compared with prior art, the utility model has following advantage:

1, the coatings of this glass has the high characteristic that reaches the high reflection of centering far infrared rays that sees through of visible light.In winter, the thermal radiation that it distributes room heater and indoor object can be as a hot mirror, and most reflected backs are indoor, guarantees that indoor heat does not does not scatter and disappear to outdoor.In summer, it can stop in the thermal radiation inlet chamber that outdoor ground, buildings send.Make building window with LOW-E glass, can reduce the indoor heat energy that causes because of radiation greatly, reach the ideal energy-saving effect to outdoor transmission.

2, this glass transmittance T (seeing through the optical throughput of transparent or semitransparent body and the percentage of its incident flux) 〉=80%; (radiant ratio is the ratio of unit surface radiating heat commensurability area black matrix radiations heat energy under uniform temp, the same terms of object in this glass radiant ratio≤0.06.The radiant ratio definition is the ability of object absorption or reflecting heat.The radiant ratio of glass approaches zero more, and its heat-insulating property is just good more).

3, this glass can be realized tempering behind the first plated film, and rete to stablize heat-resisting ability strong, the rete look diminishes after pyroprocessing.

Fig. 1 is the utility model structural representation.

[embodiment]

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:

Referring to Fig. 1, but a kind of tempering list silver LOW-E glass includes glass substrate 1, is adjacent to successively from inside to outside be compounded with five retes on the composite surface of glass substrate, and it is characterized in that: wherein first rete is that innermost layer is Si ₃N ₄ Layer 21, i.e. silicon nitride layer; Si ₃N ₄Be a kind of adamantine material, it has guaranteed that whole coating has the favorable mechanical weather resistance.Si ₃N ₄The thickness of layer is that (nm is a nanometer to 17～23nm, 1m=10 ⁹Nm).

The second layer is TiO ₂Layer 22, i.e. titanyl compound---titanium dioxide.Adopt the TiO of high refractive index n=2.5 ₂Be in order to improve the transmittance of glass, and glass is neutral color, TiO ₂The film surface is very smooth, thereby has improved the electric conductivity of silverskin.TiO ₂The thickness of layer is 20～25nm.

The 3rd layer is Ag layer 23, and argent provides lower radiant ratio, plays environmental protection and energy saving; The thickness of Ag layer is 8～14nm.

The 4th layer is NiCr layer 24; nicr layer is in order further to protect silverskin; to avoid silverskin to be subjected to etch at reactive sputtering process, also to increase so-called " blocking layer " in thin silverskin one or both sides, this NiCr has very good anti-chemistry and mechanical property for coating.The thickness of NiCr layer is 5～10nm.

Layer 5 is that outermost layer is Si ₃N ₄Layer 25, i.e. silicon nitride layer; It has guaranteed that whole coating has the favorable mechanical weather resistance.Si ₃N ₄Film is very hard, and scratch resistance, and its hardness is three times of glass, is TiO ₂Two times; Si ₃N ₄Specific refractory power be 2.05, specific absorption is almost nil, so it is fit closely as the top layer of Low-E coating.Si ₃N ₄The thickness of layer is 40～50nm.

LOW-E glass also is called low radiation coated glass.
