Ultraviolet light blocking low-radiation double-silver LOW-E hollow glass and ultraviolet-proof and double-silver LOW-E film preparation method

Abstract

The invention discloses ultraviolet light blocking low-radiation double-silver LOW-E hollow glass and an ultraviolet-proof and double-silver LOW-E film preparation method. The hollow glass comprises two glass substrates, a hollow interlayer is arranged between the two glass substrates, an ultraviolet-proof film is arranged on the outer side of each glass substrate and mainly comprises cyanuric chloride, p-aminobenzene sulfonic acid, weather-resistant agents and polyurethane curing agents, a double-silver LOW-E film layer is arranged on the inner side of each glass substrate and comprises a SiZrOx layer, a TiOx layer, a first AZO layer, a first Ag layer, a first NiCrNxOy layer, a ZnO2 layer, a first Si3N4 layer, a second AZO layer, a second Ag layer, a second NiCrNxOy layer, a second Si3N4 layer and a SiZrNy layer which are sequentially arranged on the corresponding glass substrate. The ultraviolet light blocking low-radiation double-silver LOW-E hollow glass has visible light transmittance and high infrared rejection of low-radiation LOW-E glass and can effectively absorb ultraviolet light.

Description

[0001] 【Technical field】 [0002] The invention relates to a coated glass, in particular to a low-radiation double-silver LOW-E hollow glass for blocking ultraviolet light and a method for preparing the ultraviolet-proof and double-silver LOW-E film layer. [0003] 【Background technique】 [0004] Ultraviolet light refers to sunlight between the 100-380nm band. The 100-280nm band is absorbed by the ozone layer; the 280-320nm band will cause dermal blood vessels to expand, redness, blisters, and sunburn the skin; the 320-380nm band will cause skin darkening, wrinkling, aging, loss of elasticity, serious Can cause skin cancer. At present, low-emissivity LOW-E glass is widely used in tall buildings because of its good thermal insulation and thermal insulation properties, and the utilization rate of glass windows in buildings is also increasing proportionally, especially in some high-end hotels and large office buildings. Full glass curtain wall. Although low-emissivity LOW-E gla...

Problems solved by technology

Although low-emissivity LOW-E glass has a high transmission of visible light and a good reflection of near-infrared, it blocks less than 50% of ultraviolet light. As the area of ​​glass used on building exterior walls increases The bigger it is, the more and more ultraviolet light penetrates into the room, which will not only make the indoor items aging, but also cause harm to the human body.
