Description of drawings

Fig. 1 is the two silver low radiation coated glass example structure sketch mapes of the high-transparency of the utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.

Referring to Fig. 1; Present embodiment provides a kind of high-transparency two silver low radiation coated glasses; It comprises glass 1; What adopt at this glass 1 is float glass, on this float glass 1, is coated with successively from bottom to top to be useful on first basic unit's dielectric layer 2 of increasing light transmission, second basic unit's dielectric layer 3, first barrier layer 4, first functional layer 5, second barrier layer 6, first interlayer dielectric 7, second interlayer dielectric 8, the 3rd interlayer dielectric 9, the 3rd barrier layer 10, second functional layer 11, the 4th barrier layer 12 and top layer dielectric layer 13.

Wherein, said first basic unit's dielectric layer 2 is Ti _XO, i.e. titanyl compound, the span of said X is any value between the 0.1-0.9, titanyl compound can adopt Ti ₂O ₃Or TiO ₂Said second basic unit's dielectric layer 3, first interlayer dielectric 7, the 3rd interlayer dielectric 9 are Si ₃N ₄NiCr are adopted on said first barrier layer 4, the 3rd barrier layer 10.Aluminium zinc oxide, i.e. AZO are adopted with said the 4th barrier layer 12 in said second barrier layer 6.Said first functional layer 5 and said second functional layer 11 are for containing silver film.Said second interlayer dielectric 8 is zinc tin oxide, i.e. ZnSnO ₃

In the present embodiment, in first basic unit's dielectric layer 2, the value of X is 0.5, and that promptly adopt is TiO ₂, through titanyl compound being set as anti-reflection film, said first basic unit's dielectric layer 2 has the increase light transmission features, and then can increase the light transmission of the visible light of said film system.Simultaneously, present embodiment is specially first functional layer 5 and second functional layer 11 through double-deck low-radiation film layer is set, and greatly reduces ultrared emissivity.Through said first functional layer about in the of 5 face the oxidation that first functional layer 5 has effectively been avoided on second barrier layer 6 and first barrier layer 4 is set; Through the oxidation that second functional layer 11 has been avoided on the 4th barrier layer 12 and the 3rd barrier layer 10 effectively is set up and down in second functional layer 11.Said second barrier layer 6, first barrier layer 4, the 4th barrier layer 12; And the 3rd barrier layer 10 make film system can process preliminary treatment or high-temperature process such as tempering, hot bending, its outward appearance and performance all can not be affected, and have avoided coming off of rete; Wear-resisting, non-oxidizability is better, but long term storage.In addition, the mechanical performance protection that the 3rd interlayer dielectric 9 and first intermediate dielectric 7 have been strengthened film system is set up and down, has improved the workability of film system in second interlayer dielectric 8.Described second interlayer dielectric 8 mixes colours in said film system effectively, and reduced film be before the steel with tempering after color drift.
