Embodiment 1

[0025] Using vacuum off-line magnetron sputtering coating equipment, on a 6mm high-quality float glass substrate, coatings are sequentially coated from the inside to the outside: the first layer of silicon nitride is 16nm, the thickness of the second layer of nickel-cadmium NiCr is 7.3nm, and the third The thickness of the Ag layer of the first functional layer is 7.6nm, the thickness of the fourth layer of protective layer nickel cadmium NiCr is in the range of 4.7nm, the thickness of the fifth layer of medium-reducing layer zinc aluminum oxide AZO is in the range of 3.3nm, and the sixth layer of anti-reflection layer is oxidized The thickness of titanium TiOx is between 18nm and the thickness of the seventh layer of silicon nitride SiNx is in the range of 21nm.

Embodiment 2-3

[0027] The implementation process of Embodiment 2-3 is the same as that of Embodiment 1. The thickness of the coating layer system is shown in the table below, and the unit of each layer thickness in the table is nanometer.

Abstract

The invention discloses a temperable blue low radiation energy-saving glass, the glass film structure of which comprises, in order: a glass substrate, a first layer of priming silicon nitride, a second layer of nickel-cadmium, a third layer of functional silver, a fourth layer of protective nickel-cadmium, a fifth layer of medium aluminum zinc oxide, a sixth layer of antireflection titanium oxide, and a seventh layer of silicon nitride. The low radiation glass prepared by the invention has a beautiful appearance of blue glass, suitable natural light transmittance and reflectivity. Most importantly, the low radiation glass prepared by the invention has the potential of remote processing, can undergo film coating first and then undergo cutting and tempering processing, thus greatly improving the production efficiency.

Description

technical field [0001] The invention relates to a low-radiation glass, in particular to a blue temperable low-radiation energy-saving glass. Background technique [0002] Low-emissivity energy-saving glass (LOW-E glass), its production process is to plate a multi-layer film system with silver (Ag) as the functional layer on a high-quality float substrate. At present, there are two types of off-line low-emissivity energy-saving glass processing methods: one is to first cut and edge the original float glass, and then temper and coat it to make insulating glass. One is to directly coat the original float film, and then process it by cutting, edging and tempering as required. [0003] The existing technology to produce blue glass is mostly obtained by adding an appropriate amount of metal cobalt (Co) ions to float glass. The advantage of this float glass is that it can be processed and produced in different places, but the disadvantage is that it is not as energy-saving as low-...
