The present invention relates to a low-resistance steel-contained three-silver low-
radiation coated glass and a preparation method thereof, wherein the three-silver coated layer is a laminated structure arranged in sequence: a primer layer, a first
transition layer, a first seed layer, a first functional layer, a first
barrier layer, a second
transition layer, a second
dielectric layer, a second seed layer, a second functional layer, a second
barrier layer, a third
transition layer, a third
dielectric layer, a third seed layer, a third functional layer, a third
barrier layer, a fourth transition layer, a fourth
dielectric layer and a protective layer arranged on a glass substrate. Each functional layer is a silver-
yttrium layer, and the
yttrium content accounts for 2.5%. The low-resistance steel-contained three-silver low-
radiation coated glass of the present invention has a first transition layer of
niobium oxide, which has a high
refractive index and is used as an anti-reflection material to improve the
transmittance of the entire product; the coated glass of the present invention meets the requirements for
tempering, and all indicators before and after
tempering meet the use requirements, and at the same time has the advantages of
low resistance,
high transmittance and good
processing resistance.
